The difference between in-depth analysis of virtual infrastructures & monitoringBettyRManning
This document discusses the differences between monitoring virtual infrastructures and performing in-depth analysis. Monitoring tools provide real-time insight into infrastructure health by alerting administrators if thresholds are exceeded. However, in-depth analysis goes further by systematically evaluating data according to rules and best practices to identify issues proactively and determine root causes. In-depth analysis tools can automate this process and provide recommendations to optimize systems. Such analysis reduces troubleshooting burden on administrators and helps ensure high performance, security and reliability compared to monitoring alone.

CA Infrastructure Management 2.0 vs. Solarwinds Orion: Speed and ease of mana...Principled Technologies
Infrastructure and operations support time is valuable, and every second is critical when a performance, capacity or application response issue begins to manifest. A management, alerting, and root cause analysis system that allows staff to quickly locate and troubleshoot a problem is key to providing five-nines uptime SLAs, as well as keeping a business’s own staff working at peak efficiency.
In our tests, we found that CA Infrastructure Management 2.0 outperformed the SolarWinds Orion tools in tests of ease of use and required-time-to-complete. The testing demonstrated timing wins for CA Technologies in our four simulated scenarios, by factors of 2.3 to 11.4 times over SolarWinds Orion.
When managing large-scale infrastructures, the ability to efficiently triage a large number of devices and network links is essential for maintaining high availability, consistent performance and routine business operations. This is particularly evident when calculating the aggregate time saved when performing the same operations multiple times in a given day. Over time, these aggregate figures can lead to significant savings of time and money for your organization.

This is a paper was written by David Reine, an IT analyst for The Clipper Group, and highlights IBM’s SAN Volume Controller new features, capabilities and benefits. These new capabilities were announced on October 20, 2009Virtualization is at the center of all 21st Century IT systems, yet many CIOs fail to fully understand all of the benefits it can deliver to the data center operation. When we think of virtualization, we think compute, network, and storage—and we mostly think about driving up utilization on each. Storage controllers have always offered the ability to carve out pieces of real storage from a large pool and deliver them efficiently to a number of hosts, but it is storage virtualization itself that offers improvements that drive operational efficiency. IBM has been quietly addressing storage virtualization with SAN Volume Controller (SVC) for the last six years, building up a significant technical lead in this space.
Strange but true: most infrastructure architectures are deliberately designed from the outset to need little or no change over their lifetimes. There are two main reasons for this:
1. Change often means outages and customer impact and must be avoided
2. Budgets are set at the beginning of a project and getting more cash later is tough
Typically, then, applications are configured with all of the storage capacity they need to support the wildest dreams of their business sponsors (and then some extra is added for contingency by IT). Equally, storage is always configured with the performance level (storage tier) set to cope with the wildest transactional dreams of the business sponsor (and guess what? IT generally adds a bit more for good measure.).
No wonder storage is now one of the largest cost components involved in delivering and running a business application.

Challenge
Managing uptime and performance is critical to any environment. With virtualization, however, it changes the game
significantly when you consider the increased complexities involved in managing the interdependencies between
virtual machines (VMs) and the underlying physical infrastructure that supports them. As organizations become more
dependent on virtualization, it’s becoming increasingly critical, and challenging, to manage it effectively and to ensure
optimal uptime and availability.
As organizations mature in their use of virtualization, they encounter challenges along the way that are unique to
virtualized environments. These challenges eventually disrupt many of the management techniques traditionally
used. A reactive management approach typically only provides a temporary fix, which allows problems to resurface
later. The challenge ensues because many organizations are simply unaware of the extent of the additional
complexities virtualization introduces and why it makes management more complicated. A few examples of the
complexities introduced by server virtualization are:
Traditional infrastructure assigns specific hardware to specific applications, or ―share nothing,‖ providing
exclusive use of resources (except maybe disk)
Virtual infrastructure, in most cases, is share everything: shared resources across CPU, memory, network
and disk
More complicated still is the fact that a virtual machine (VM) is just a process that co-exists with others, sharing time
and access to resource availability and prioritization of needs. The impact of shared resources can have a resounding
effect on the performance of your overall VM environment – the source of many performance bottlenecks can be
directly traced to one form of resource contention or another. An example of this includes one VM starving another of
resources, like storage, CPU and memory – this happens when there are too many VMs running on one host.
The hypervisor itself can introduce specific issues. This becomes evident when attempting to manage memory
contention on VMs and running into memory limit issues, which are often difficult to detect, yet easy fix. The guest VM
may be configured to use a larger amount of memory than what is configured on the hypervisor (a hard limit setting).
This results in the guest requesting more memory than the hypervisor is allowing, leading to serious performance
problems. Reliance on metrics commonly used to measure physical environments (e.g. time metrics like I/O per
second) within a VM guest are misleading and do not provide any value in this case.
This tech brief explores the primary attributes of a solution that not only detects, diagnoses and resolves performance
bottlenecks in virtualized infrastructures quickly and efficiently, but also reduces risk and improves performance,
uptime and efficiency.
4. Tech Brief – Destroying Performance Bottlenecks Across Diverse VM Environments 4
Determining the Real Root Cause
Determining the root cause of problems is the most important step to reducing overall mean-time-to-resolution
(MTTR). In virtualized environments, however, finding the root cause is even more elusive. Sharing resources across
physical hosts and multiple virtual guests not only makes it difficult to pinpoint the genuine underlying root cause of a
problem, it also makes it difficult to get relevant information required to solve the issue.
Inefficient and costly practices – like blindly throwing more disk, memory, processor or hardware at a problem – are
not sufficient. In most cases, this approach simply masks the situation (and in all probability, the problem will return
with worse consequences). This situation provides a good example where virtualization-specific solutions are
needed. Traditional physical monitoring tools simply do not provide sufficient visibility into the virtual layer.
For example, let’s say a VM is experiencing a performance slowdown. Manual and simplistic management
techniques may reveal high disk swapping, but without insight into the virtual layer and proper virtualization-specific
diagnostics, users may not know that swapping had occurred because of an inflated balloon memory driver. This
could lead the user to a false diagnosis. In this case, a virtualization-specific solution provides the user with relevant
data, visibility into the root cause, and a resolution course of action (e.g. resetting the balloon driver).

A fast path to resolution is a required course of action for effectively killing bottleneck issues. A competent tool can
achieve this quickly, providing certainty that the root cause was isolated, addressed and resolved. This can best be
accomplished through the establishment of automated best-practice responses to remediating performance
bottlenecks.
Having the ability to be notified of relevant alarm details and then launch workflows specific to fast remediation of the
problem applies consistency to problem solving and speeds MTTR. This approach accelerates problem diagnosis
and correction, as well as increases staff efficiency by taking manual troubleshooting out of the equation. When using
an effective detect, diagnose and resolve (DDR) foundation, users must rely on a tool to present data on the
following:
Best Practices: A tool must alert users to conditions that are not satisfactory under normal ―best practices,‖
such as setting limits and thresholds
Impact Visibility: Visibility into whether configuration settings are correct, or are the root of a larger issue

Achieving the Level of Visibility You
Need
Effective virtualization performance monitoring and management also hinges on having sufficient visibility and control
of diverse and increasingly complex virtual environments. Users must rely on the necessary visibility (from their own
view), and either verify that problems were fixed, or continually monitor the state and health of their virtual
environment (Figure 3). Many tools make it overwhelming to zero in on the values and systems they are concerned
with at any given time. Administrators must be able to take any data point, or observation value, and tailor the
information to what they want/need to see, and not be hindered by a dashboard that only presents limited information.

Custom dashboards should also include the necessary visibility into the virtual infrastructure through the display of
important information relevant to the specific job functions of various stakeholders. Service views, such as in Figure
4, provide a comprehensive view of a service while being managed in a virtual environment, complete with data
supporting overall service levels and real-time state and health indicators. These views, along with detailed reporting,
act as invaluable resources for communicating with the rest of the business.
