  12. 12. Preface This IBM® Redbook is a study guide for IBM Tivoli® Monitoring Version 6.1 and is aimed at the people who want to get an IBM Professional Certification for this product. The IBM Tivoli Monitoring Version 6.1 Certification, offered through the Professional Certification Program from IBM, is designed to validate the skills required of technical professionals who work in the implementation of the IBM Tivoli Monitoring Version 6.1 product. This book provides a combination of theory and practical experience needed for a general understanding of the subject matter. It also provides sample questions that will help in the evaluation of personal progress and provide familiarity with the types of questions that will be encountered in the exam.

  26. 26. 2 Chapter 2. Planning The keys to a successfully deployment of IBM Tivoli Monitoring V6.1 are proper architecture planning and requirements collection. This chapter summarizes the various core IBM Tivoli Monitoring V6.1 components and how each one relates to one another. We examine several common architecture designs based on several factors: number of agents, hardware availability, and network restrictions. In this chapter, we discuss the following topics: IBM Tivoli Monitoring V6.1 components IBM Tivoli Monitoring V6.1 deployment scenarios Scalability© Copyright IBM Corp. 2006. All rights reserved. 11
  27. 27. 2.1 IBM Tivoli Monitoring V6.1 components An IBM Tivoli Monitoring V6.1 installation consists of several components collectively labeled the Tivoli Monitoring Services framework. This framework consists of several core components. There are optional components that can be installed to extend the monitoring framework features. In the following sections, we discuss these core and optional IBM Tivoli Monitoring V6.1 components.2.1.1 Tivoli Enterprise Monitoring Server Tivoli Enterprise Monitoring Server (referred to as the monitoring server) is the first component installed to begin building the IBM Tivoli Monitoring Services foundation. All other core components directly interface with this one single core component. Tivoli Enterprise Monitoring Server acts as a collection and control point for alerts received from agents and collects their performance and availability data. Tivoli Enterprise Monitoring Server is responsible for tracking the heartbeat request interval for all the Tivoli Enterprise Monitoring Agents connected to it. The monitoring server stores, initiates, and tracks all situations and policies. It is the central repository for storing all active conditions and short-term data about every Tivoli Enterprise Monitoring Agent. The responsibility of Tivoli Enterprise Monitoring Server includes initiating and tracking all generated actions that invoke a script or program on the Tivoli Enterprise Monitoring Agent. The Tivoli Enterprise Monitoring Server storage repository is a proprietary database format (referred to as the Enterprise Information Base, EIB) grouped as a collection of files located on Tivoli Enterprise Monitoring Server. These files start with the file name prefix qa1 and are in: <installation_dir/tables/<tems_name> <installation_dir>: IBM Tivoli Monitoring V6.1 home directory <tems_name>: Tivoli Enterprise Monitoring Server name Note: <tems_name> is the monitoring server name, not necessarily the Tivoli Enterprise Monitoring Server host name. The primary Tivoli Enterprise Monitoring Server is configured as a hub (*LOCAL). All IBM Tivoli Monitoring V6.1 installations require at least one Tivoli Enterprise Monitoring Server configured as a hub. Additional remote12 Certification Guide Series: IBM Tivoli Monitoring V6.1
  28. 28. (*REMOTE) Tivoli Enterprise Monitoring Servers can be installed afterward to introduce a scalable hierarchy into the architecture. This hub/remote interconnection provides a hierarchical design, enabling the remote Tivoli Enterprise Monitoring Server to control and collect its individual agent status and propagate the agent status up to the hub Tivoli Enterprise Monitoring Server. This mechanism enables the hub Tivoli Enterprise Monitoring Server to maintain an infrastructure for wide visibility of the entire environment. This visibility gets passed to the Tivoli Enterprise Portal Server for preformatting, ultimately displaying within the Tivoli Enterprise Portal client. If security validation is configured, a separate procedure is necessary to manage the OS-level user IDs at the hub Tivoli Enterprise Monitoring Server. User access is managed within IBM Tivoli Monitoring V6.1 through the Tivoli Enterprise Portal GUI only. A matching user ID must be defined at the hub Tivoli Enterprise Monitoring Server (including the Hot Standby) using the standard user management process for that hub Tivoli Enterprise Monitoring Server operating system. How the Hot Standby works: When there is a failure on the acting primary hub Tivoli Enterprise Monitoring Server When the switch is initiated by a user on a Tivoli Enterprise Monitoring Server There is no automatic switch when the primary comes back up. The Hot Standby expects the primary hub Tivoli Enterprise Monitoring Server and the alternate (standby) hub Tivoli Enterprise Monitoring Server to be at the same capacity. Internally, Hot Standby considers them peers and does not distinguish in terms of a primary and a secondary. Instead, it handles them as acting-primary and acting-secondary. Both hub Tivoli Enterprise Monitoring Servers alternate between being acting-primary and acting-secondary. By default, the algorithm that the Hot Standby follows to determine which is the acting-primary hub Tivoli Enterprise Monitoring Server is to query the two monitoring servers to determine how long they have been up. The hub Tivoli Enterprise Monitoring Server that has been up the longest wins.2.1.2 Tivoli Enterprise Portal Server Tivoli Enterprise Portal Server (referred to as the portal server) is a repository for all graphical presentation of monitoring data. The portal server is responsible for the management of user IDs and user access controls for the monitoring workspaces, situations, and policies. Tivoli Enterprise Portal Server provides the core presentation layer that allows for retrieval, manipulation, analysis, and Chapter 2. Planning 13
  29. 29. preformatting of data. It manages this access through user workspace consoles. The portal server keeps a persistent connection to the hub Tivoli Enterprise Monitoring Server, and can be considered a logical gateway between the hub Tivoli Enterprise Monitoring Server and the Tivoli Enterprise Portal client. Any disconnection between the two components immediately disables access to the monitoring data used by the Tivoli Enterprise Portal client. An RDBMS must be installed on the same physical system prior to the Tivoli Enterprise Portal Server installation. This prerequisite is necessary because the portal server installation will create the mandatory Tivoli Enterprise Portal Server database, along with the supporting tables. Additionally, an Open Database Connectivity (ODBC) data source name is configured to connect directly to the Tivoli Data Warehouse RDBMS. This OBDC connection is used whenever a pull of historical data from the Tivoli Data Warehouse is requested. Note: Even though technically valid, implementing a remote RDBMS for the Tivoli Enterprise Portal Server is not recommended. Tivoli Enterprise Portal Server is closely coupled to the RDBMS and the complexity of a remote RDBMS is difficult to maintain. When the Tivoli Enterprise Portal Server, a propriety integrated Web server is installed for use with the Tivoli Enterprise Portal client in browser mode. Depending on the network topology and possible security implications, this might play a role in constructing the solution. Instead, an external Web server installed on the same system as the portal server can be used. Refer to Chapter 9 of IBM Tivoli Monitoring Installation and Setup Guide, Version 6.1.0, GC32-9407, for additional details. In large installations, we recommend that you install multiple Tivoli Enterprise Portal Server that connects to one single hub Tivoli Enterprise Portal Server.2.1.3 Tivoli Enterprise Portal The Tivoli Enterprise Portal client (referred to as the portal client) is a Java™-based user interface that connects to the Tivoli Enterprise Portal Server to view all monitoring data collections. It is the user interaction component of the presentation layer. Tivoli Enterprise Portal consolidates all these views into a single window, enabling complete visibility to any non-functioning component. The client offers two modes of operation: a Java desktop client and an HTTP browser. Assuming a default installation, for the browser mode Tivoli Enterprise Portal client, use the following URL: http://<hostname>:1920///cnp/kdh/lib/cnp.html14 Certification Guide Series: IBM Tivoli Monitoring V6.1
  30. 30. Where <hostname> is the host name of the Tivoli Enterprise Portal Server. Note: IBM Tivoli Monitoring V6.1 only supports Microsoft® Internet Explorer on the Microsoft Windows® platform in browser mode. The following products have integrated interfaces into Tivoli Enterprise Portal: IBM Tivoli OMEGAMON Z IBM Tivoli OMEGAMON Distributed IBM Tivoli OMEGAMON XE for WebSphere Business Integration IBM Tivoli Monitoring V5.1.2 IBM Tivoli Monitoring V6.1 IBM Tivoli NetView® for z/OS® (Release 5.2) IBM Tivoli Enterprise Console IBM Tivoli Composite Application Manager for Response Time Tracking IBM Tivoli Composite Application Manager for SOA IBM Tivoli Composite Application Manager for WebSphere Note: In 2006, additional products such as IBM Tivoli Service Level Advisor, System Automation, and IBM Tivoli Business System Manager will also be integrated into Tivoli Enterprise Portal. IBM Tivoli Service Level Advisor integrations will be available with Tivoli Data Warehouse V2.1.1.2.1.4 Tivoli Enterprise Monitoring Agent The agents (referred to as managed systems) are installed on the system or subsystem requiring data collection and monitoring. The agents are responsible for data gathering and distribution of attributes to the monitoring servers, including initiating the heartbeat status. The agents test attribute values against a threshold and report these results back to the monitoring servers. An alert icon is displayed in Tivoli Enterprise Portal when a threshold is exceeded or a value is matched. These tests are called situations. The following situations prompt the monitoring server to gather data samples from the agents: Opening or refreshing a workspace that has data views (table or chart views). When this happens, Tivoli Enterprise Portal Server sends a sampling request to the hub Tivoli Enterprise Monitoring Server. The request is passed to the Chapter 2. Planning 15
  31. 31. monitoring agent if there is a direct connection, or through the remote Tivoli Enterprise Monitoring Server to which the monitoring agent connects. The monitoring agent takes a data sampling and returns the results through the monitoring server and portal server to the portal workspace. The sampling interval for a situation (a test taken at your monitored systems). This situation can have an interval as often as once per second or as seldom as once every three months. When the interval expires, the monitoring server requests data samples from the agent and compares the returned values with the condition described in the situation. If the values meet the condition, the icons change on the navigation tree. Optionally, the agents can be configured to transfer data collections directly to the Warehouse Proxy Agent instead of using the remote Tivoli Enterprise Monitoring Server. If firewall restrictions are disabled or at a minimum, we recommend that you configure all the agents to transfer directly to the Warehouse Proxy Agent. Otherwise, firewall security is a key factor in the location of the Warehouse Proxy Agent respective to the firewall zone and agents. Warehousing data through the remote Tivoli Enterprise Monitoring Server is limited and should only be used as a last resort. Tivoli Enterprise Monitoring Agents are grouped into two categories: Operating System (OS) Agents Operating System Agents retrieve and collect all monitoring attribute groups related to specific operating system management conditions and associated data. Application Agents Application Agents are specialized agents coded to retrieve and collect unique monitoring attribute groups related to one specific application. The monitoring groups are designed around an individual software application and provide in-depth visibility into the status and conditions of that particular application. The examples of included common monitoring agents include: Microsoft Windows OS Agent Linux OS Agent UNIX® OS Agent UNIX Log Agent (also supports logs on Windows) IBM i5/OS® Agent IBM Tivoli Universal Agent The Universal Agent is a special agent that leverages a full application programming interface (API) to monitor and collect data for any type of16 Certification Guide Series: IBM Tivoli Monitoring V6.1
  32. 32. software. The Universal Agent can monitor and retrieve data from any application that produces data values. Essentially, IBM Tivoli Monitoring V6.1 can now monitor any unique application regardless of whether the base product supports it. Examples of optional monitoring agents include: Monitoring Agent for IBM Tivoli Monitoring 5.x Endpoint DB2® Agent Oracle Agent Microsoft SQL Agent Microsoft Exchange Agent Active Directory Agent2.1.5 Warehouse Proxy Agent The Warehouse Proxy Agent is a unique agent that performs only one task. The Warehouse Proxy Agent collects and consolidates all the historical data collections from the individual agents to store in the Tivoli Data Warehouse. If using Tivoli Data Warehouse, one Warehouse Proxy Agent is required for each IBM Tivoli Monitoring V6.1 installation. It uses Open Database Connectivity (ODBC) to write the historical data to a supported relational database. Restriction: IBM Tivoli Monitoring V6.1 currently only supports the Warehouse Proxy Agent under the Microsoft Windows platform. UNIX operating support for the Warehouse Proxy Agent will be in a post-GA release of IBM Tivoli Monitoring V6.1.2.1.6 Warehouse Summarization and Pruning Agent The Summarization and Pruning Agent is a unique agent that performs the aggregation and pruning functions for the historical raw data on Tivoli Data Warehouse. It has advanced configuration options, enabling exceptional customization of the historical data storage. A Summarization and Pruning Agent is recommended to manage the historical data in Tivoli Data Warehouse. Due to the tremendous amounts of data processing necessary, we recommend that you always install the Summarization and Pruning Agent on the same physical system as the Tivoli Data Warehouse repository. Chapter 2. Planning 17
  33. 33. 2.1.7 Tivoli Data Warehouse IBM Tivoli Data Warehouse is the database storage that contains all the historical data collection. A Warehouse Proxy must be installed to leverage the Tivoli Data Warehouse function within the environment. In large-scale deployments, Tivoli Data Warehouse can be shared between monitoring installations.2.1.8 Optional IBM Tivoli Monitoring V6.1 components Note the following optional IBM Tivoli Monitoring V6.1 components. Monitoring Agent for IBM Tivoli Monitoring 5.x Endpoint This integration agent enables the collection and visualization of IBM Tivoli Monitoring V5.x resource models in Tivoli Enterprise Portal. The visualization is the direct replacement for the Web Health Console. Additionally, the agent provides a rollup function into the Tivoli Data Warehouse. Tivoli Enterprise Console event synchronization The event synchronization component sends updates to situation events back to the monitoring server that are forwarded to the event server. Actions performed at the Tivoli Enterprise Console for IBM Tivoli Monitoring V6.1 situations are reflected in Tivoli Enterprise Portal Server.2.2 IBM Tivoli Monitoring V6.1 deployment scenarios Deployment scenarios attempt to provide a realistic understanding of architecture design. Use these scenarios for guidance to assist in the planning and deployment strategy used for a production installation. It is important to recognize that every deployment strategy is unique, and only proper planning can guarantee a successful implementation.2.2.1 Small/medium installation (500 agents maximum) The small/medium installation is the fundamental design using only the minimum required components. This scenario is perfect for prototyping IBM Tivoli Monitoring V6.1 or using it within a production installation consisting of 500 agents. In fact, IBM Tivoli Monitoring V6.1 by design excels in superiority for the small/medium installation. The out-of-the-box monitoring collections, GUI presentation layer, historical data collection, and robustness provide a full monitoring solution with a modest total cost of ownership (TCO).18 Certification Guide Series: IBM Tivoli Monitoring V6.1

It is implemented with the minimum hardware requirements necessary for aproduction IBM Tivoli Monitoring V6.1 installation.The installation consists of the following components: Tivoli Enterprise Monitoring Server Tivoli Enterprise Portal Server Tivoli Enterprise Portal Tivoli Warehouse Proxy Agent Tivoli Data Warehouse Summarization and Pruning AgentFigure 2-1 on page 19 depicts the small/medium topology.

Planning 19
  35. 35. installation allows the use of only one Tivoli Enterprise Monitoring Server. Implementing a hub/remote architecture in the early stages allows for growth and scalability. Furthermore, this design builds around IBM Tivoli Monitoring V6.1 built-in fail-over capabilities. The small/medium installation supports approximately 250 managed systems. This estimate assumes that each managed system will have two agents each. The actual distribution of agents will not necessary be proportionate in a real installation, but this calculation provides the recommended total amount for one IBM Tivoli Monitoring V6.1 installation. All the agents will connect to the remote Tivoli Enterprise Monitoring Server, only using the hub Tivoli Enterprise Monitoring Server as a fail-over monitoring server. We recommended installing the optional the Hot Standby node. However, the Hot Standby is not required for the small/medium installation, especially if cost restrictions exist for hardware deployment. Always consider the Hot Standby, because it offers failure protection with a minimum increase in the total cost of ownership. Note: A small/medium installation cannot use a remote Tivoli Enterprise Monitoring Server as a Hot Standby node. Hot Standby nodes always need to be configured as *LOCAL. It is permitted to use the hub Tivoli Enterprise Monitoring Server to handle agent tasks directly. However, we do not recommend using the hub Tivoli Enterprise Monitoring Server for this purpose. The hub Tivoli Enterprise Monitoring Server should focus on data collecting and processing tasks between the Tivoli Enterprise Portal Server and itself. If the environment expands, install additional remote Tivoli Enterprise Monitoring Servers to process the additional agent requirement. Additional agent deployments increase the processing requirements for the hub Tivoli Enterprise Monitoring Server, which can degrade if the hub is allowed to handle agent tasks directly. For an average Tivoli Data Warehouse installation within a small/medium installation, it should be sufficient to have the Warehouse Proxy Agent and the Tivoli Data Warehouse repository on the same system. This installation provides historical data collection without the additional hardware. It is still a wise decision to monitor the Tivoli Data Warehouse after the installation to ensure that the processing rate is on target.2.2.2 Large installation (5000 agents maximum) The large installation builds on the fundamentals of the small/medium installation. This design focuses on scalability. This IBM Tivoli Monitoring environment consists of 5000 agents within a single Tivoli Monitoring installation.20 Certification Guide Series: IBM Tivoli Monitoring V6.1
  36. 36. It requires the recommended hardware specification or higher to properly scalethe infrastructure.The installation consists of the following components: Tivoli Enterprise Monitoring Server Tivoli Enterprise Portal Server Tivoli Enterprise Portal Tivoli Warehouse Proxy Agent Tivoli Data Warehouse Summarization and Pruning Agent Tivoli Enterprise ConsoleFigure 2-2 on page 22 depicts the comprehensive architecture for allinterconnected components.

In a large installation, we strongly recommend that you implement the Hot Standby node. Performing an accurate plan and assessment stage is imperative for the large installation. Mapping all component topology with the recommended hardware specifications is critical in order to achieve a highly distributed environment with realistic goals. We recommend having a thorough understanding of the monitoring environment before preceding to implement any architectural design. It is important to account for all variables within the topology. Substantial consideration should be given to the infrastructure hardware requirements and the underlying network topology. Network bandwidth, latency, and firewall restrictions all require assessments.22 Certification Guide Series: IBM Tivoli Monitoring V6.1
  38. 38. A large monitoring installation will support approximately 1,500 managed systems within an environment. For the large installation, the estimate is three agents per managed system. In this installation, a disproportionate distribution of agents is highly anticipated, and this scenario should compliment your own environment analysis phrase. The recommended distribution is 500 agents across 10 remote Tivoli Enterprise Monitoring Servers. Keeping 500 agents as the high point per monitoring server allows for capacity expansion without exhausting the resources of the infrastructure. Tip: Because IBM Tivoli Monitoring V6.1 supports primary and secondary communication paths, we highly recommend that you install several backup remote Tivoli Enterprise Monitoring Servers that exist solely for Tivoli Enterprise Monitoring Agent fail-over capabilities. When a failure of a remote Tivoli Enterprise Monitoring Server occurs, it is not advisable to double the maximum load of a production remote Tivoli Enterprise Monitoring Server. Best practices should direct these orphan Tivoli Enterprise Monitoring Agents to the idle remote Tivoli Enterprise Monitoring Server. The Tivoli Data Warehouse data requirement will be a substantial amount. We advise separating the Tivoli Warehouse Proxy Agent and the Tivoli Data Warehouse repository between two systems. Install the Summarization and Pruning Agent on the Tivoli Data Warehouse system. We always recommend that you keep these two components together. The large installation introduces IBM Tivoli Enterprise Console as part of the topology. IBM Tivoli Monitoring V6.1 has built-in capabilities for event processing that work extremely well in the small/medium installation. However, the large installation can contain a reasonable increase in volume of event flow, and IBM Tivoli Enterprise Console is better adapted for large event flow management and correlation. Tivoli Enterprise Console can be considered an event consolidation manager of managers. The TCO is still nominal compared to IBM Tivoli Monitoring V6.1 functionality, despite the large hardware requirements necessary to scale this installation properly. The entire large installation can be managed from a single GUI presentation layer down to installing and upgrading agents.2.2.3 Huge installation (more than 5000 agents) The huge installation scenario provides a guideline for any IBM Tivoli Monitoring installation that exceeds 5000 agents, or approximately 1,500 managed systems. The scope of the huge installation is similar to the large installation, except for additional configuration guidance. Chapter 2. Planning 23

Enormous amounts of data can be collected between two large IBM Tivoli Monitoring V6.1 installations. Best practice design is critical to ensure a stable, scalable environment. Chapter 2. Planning 25
  41. 41. The two installation are still built separately from each other. The only deviation is that one IBM Tivoli Monitoring V6.1 installation requires a logical association as the master control for the Summarization and Pruning Agent. Restriction: There can only be one Summarization and Pruning Agent for a single Tivoli Data Warehouse. Because the Summarization and Pruning Agent requires connections to a Tivoli Enterprise Monitoring Server, one of the monitoring installations needs a logical designation as the master. This is not a programmatic assignment, but a logical identification for the configuration and management of the Summarization and Pruning Agent. Communications protocol selection If installing IBM Tivoli Monitoring V6.1 components across firewalls, we recommend that you configure the IP.PIPE (TCP communication) protocol. The IP (UDP communication) protocol is insufficient for firewall configurations. The connectionless UDP protocol requires opening up multiple ports across firewalls to allow multiple connections from each individual IBM Tivoli Monitoring V6.1 component. For example, a Tivoli Enterprise Monitoring Agent communicating to the Tivoli Enterprise Monitoring Server using IP (UDP communication) protocol requires multiple ports to operate properly. Secondly, using the IP.PIPE (TCP communication) will enable the Ephemeral Pipe Support (EPS) operation automatically if certain conditions match. Table 2-1 depicts the default listening ports for the IBM Tivoli Monitoring V6.1 components. Use this table as a quick reference to understand the standard ports for an installation. Although supported, we recommend that you do not modify these default values. Table 2-1 Default port usage for IBM Tivoli Monitoring V6.1 IBM Tivoli Monitoring V6.1 component Listening port Tivoli Enterprise Monitoring Server (IP.PIPE) 1918/TCP Tivoli Enterprise Monitoring Server (IP.SPIPE) 3660/TCP Tivoli Enterprise Monitoring Server (IP) 1918/UDP Tivoli Enterprise Portal Server 1920/TCP 15001/TCP Tivoli Enterprise Console 5529/TCP Tivoli Warehouse Proxy Agent 6014/TCPa a. Refer to the calculation on page 27.26 Certification Guide Series: IBM Tivoli Monitoring V6.1
  42. 42. Using IP.PIPE allows a few well know ports to be open through the firewall. Use Table 2-1 on page 26 to calculate which port to open. If the firewall is not using network address translation (NAT), the computation should be sufficient to have the components connect through the firewall. Every system that has IBM Tivoli Monitoring V6.1 installed will automatically reserve the well-known port (default 1918) for Tivoli Enterprise Monitoring Server communication. It does not matter in which order components start on a system that has several IBM Tivoli Monitoring V6.1 components installed; the default well-known port is only used by Tivoli Enterprise Monitoring Server. Note: Port 1918 is the default well-known port. Any well-known port can be configured, as long as the entire environment matches this port number. For all other components except for the Tivoli Enterprise Monitoring Server, the following calculation is used internally by IBM Tivoli Monitoring V6.1 to reserve the listening ports. “reserved port” = well-known port + (N*4096) Where: N= startup sequence For example, the IBM Tivoli Monitoring V6.1 component startup on the system Izmir follows this sequence: 1. The Universal Agent starts first: port 6014 (1918 + 1*4096). 2. The remote Tivoli Enterprise Monitoring Server starts second: port 1918 (always reserved for Tivoli Enterprise Monitoring Server). 3. The Windows OS Agent starts third: port 10110 (1918 + 2*4096). 4. The Warehousing Proxy starts fourth: port 14206 (1918 + 3*4096).2.3 Scalability A distributed networking infrastructure inherits scalable characteristics by design. After all, a distributed system is built to expand and shrink through the increment and decrement in hardware capacity. Scalability is not the same as performance tuning. Performance tuning deals with increasing the output from the current capacity without adding additional resources. You must make this decision carefully, because different sources have their own reasons for providing sizing metrics. Chapter 2. Planning 27
