Active Directory is critical Windows infrastructure that allows users to access network resources and authenticate. It is important to monitor Active Directory to prevent outages that can block all users. OpManager monitors Active Directory by checking the availability and performance of services, resources, processes, and event logs to detect and alert on issues before they seriously impact users. It monitors over 50 Active Directory parameters and provides dashboards and alerts to help administrators address problems promptly.

"Wire Encryption In HDFS: Protect Your Data From Others, Not Yourself"
ApacheCon 2019, Las Vegas.
SPEAKERS: Chen Liang, Konstantin Shvachko. LinkedIn
Wire data encryption is a key component of the Hadoop Distributed File System (HDFS). HDFS can enforce different levels of data protection, allowing users to specify one based on their own needs. However, such enforcement comes in as an all-or-nothing feature. Namely, wire encryption is enforced either for all accesses or none. Since encryption bears a considerable performance cost, the all-or-nothing condition forces users to choose between 'faster but unencrypted' or 'encrypted but slower' for all clients. In our use case at LinkedIn, we would like to selectively expose fast unencrypted access to fully managed internal clients, which can be trusted, while only expose encrypted access to clients outside of the trusted circle with higher security risks. That way we minimize performance overhead for trusted internal clients while still securing data from potential outside threats. We re-evaluate the RPC encryption mechanism in HDFS. Our design extends HDFS NameNode to run on multiple ports. Depending on the configuration, connecting to different NameNode ports would end up with different levels of encryption protection. This protection then gets enforced for both NameNode RPC and the subsequent data transfers to/from DataNode. System administrators then need to set up a simple firewall rule to allow access to the unencrypted port only for internal clients and expose the encrypted port to the outside clients. This approach comes with minimum operational and performance overhead. The feature has been introduced to Apache Hadoop under HDFS-13541.

In this session, we walk through the Amazon VPC network presentation and describe the problems we were trying to solve when we created it. Next, we walk through how these problems are traditionally solved, and why those solutions are not scalable, inexpensive, or secure enough for AWS. Finally, we provide an overview of the solution that we've implemented and discuss some of the unique mechanisms that we use to ensure customer isolation, get packets into and out of the network, and support new features like VPC endpoints.
Many applications are network I/O bound, including common database-based applications and service-based architectures. But operating systems and applications are often untuned to deliver high performance. This session uncovers hidden issues that lead to low network performance, and shows you how to overcome them to obtain the best network performance possible.
Learn to recognize the many ways in which attackers can tamper with DNS servers and records, and the measures you can take to prevent this.

The high level of automation for the container and microservice lifecycle makes the monitoring of Kubernetes or Swarm more challenging than in more traditional, more static deployments. Any static setup to monitor specific application containers does not work because orchestration tools like Kubernetes or Swarm make their own decisions according to the defined deployment rules. In this talk you will learn how DevOps can cope with challenges in Monitoring and Log Management on Docker Swarm and Kubernetes. We will start with the basics of container monitoring and logging, including APIs and tools, followed by an overview of the key metrics of both platforms. We will speak about cluster-wide deployments for monitoring and log management solutions and how to discover services for log collection and monitoring, tagging of logs and metrics. Finally, we will share insights derived from monitoring a 4700 node Swarm cluster, as part of the Swarm3k project.

Securing Your Enterprise Web Apps with MongoDB Enterprise MongoDB
Speaker: Jay Runkel, Principal Solution Architect, MongoDB
Level: 200 (Intermediate)
Track: Operations
When architecting a MongoDB application, one of the most difficult questions to answer is how much hardware (number of shards, number of replicas, and server specifications) am I going to need for an application. Similarly, when deploying in the cloud, how do you estimate your monthly AWS, Azure, or GCP costs given a description of a new application? While there isn’t a precise formula for mapping application features (e.g., document structure, schema, query volumes) into servers, there are various strategies you can use to estimate the MongoDB cluster sizing. This presentation will cover the questions you need to ask and describe how to use this information to estimate the required cluster size or cloud deployment cost.
What You Will Learn:
- How to architect a sharded cluster that provides the required computing resources while minimizing hardware or cloud computing costs
- How to use this information to estimate the overall cluster requirements for IOPS, RAM, cores, disk space, etc.
- What you need to know about the application to estimate a cluster size

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Monitoring active-directory
1. Monitoring Active Directory Using OpManager
Active Directory is Microsoft’s implementation of LDAP directory services for Windows
environments. It allows administrators to implement company wide policies on access to
resources and services by the users. Active Directory is usually installed in Windows 2003 or 2000
server and together they are called the Domain Controllers. If active directory fails, it would
affect the entire user base, as they won’t be able to logon to their systems, access critical
information from other servers, or send/receive emails.
In this section lets see how a Network Monitoring Tool such as OpManager can help
administrators prevent Active Directory nightmares!
2. A Sample Active Directory Nightmare
Imagine a scenario where your CEO logs into his laptop and it says access denied. Probably he
just forgot to release the CAPS LOCK key (you are saved) or the Kerberos Key Distribution Center
Service that plays a vital role in user authentication has stopped functioning and is forcing every
Windows user from logging into the domain (you are in trouble). There is no way your CEO could
imagine that a simple service running at a server in an isolated room could stop him from
working. All that everybody wants is uninterrupted network access.
Most of the IT helpdesk tickets originate from issues spawning from users trying to access
resources outside one’s computer. Active directory forms the crux of this ever-active access
system. For instance common operations such as user authentication, exchange mail routing,
depend on Active Directory. This makes continuous monitoring of Active Directory and related
services very important – so that you may also stay away from nasty nightmare!
What should you monitor in active directory?
There are a little over half-a-dozen Active Directory components that can cause an access
problem to a user. Few important factors that you need to monitor on AD are:
• System Resources Availability
• Responsiveness of LDAP
• Availability of DNS Client Service
• Availability of Kerberos Key Distribution Center Service
• Availability of Net Log On Service
• Health of File Replication Service (FRS)
System Resources Availability: Hardware failures, insufficient disk space etc., are common
problems causing a server to crash. Requests to the Active Directory need to be served fast. This
requires the CPU, Memory, and Disk Space of the server that hosts Active Directory to be running
at optimal levels and monitored 24*7.
Responsiveness of LDAP: LDAP is the client used to retrieve directory information. Monitoring
LDAP parameters like LDAP Bind Time, number of Active Connections, LDAP Searches, and LDAP
Writes is a proactive step in ensuring its availability.
Availability of DNS Client Service: DNS lookup failure can cause problems. The Domain
Controller might not have been able to register DNS records, which actually vouches for the
Domain Controllers availability. This results in the other Domain Controllers, users, and
computers in the domain in not locating this DC which again might lead to replication failure.
Refer this article for troubleshooting AD related DNS problems.
Availability of Kerberos Key Distribution Center Service: Active Directory depends on this
service for authentication. Failure of this service leads to log-on failures. Refer this article to
know how this service works.
Availability of Net Log On Service: Request to authenticate users is served by this service.
Failure of this service also makes the log-on impossible. The Domain Controller will not be able
3. to accept log-on requests if this service is not available.
Health of File Replication Service (FRS): FRS service replicates the objects in Active Directory
among all the Domain Controllers in a network (if you have more than one domain controller).
This is done to ensure round-the-clock accessibility to the information on the AD. This can be
across the LAN or the WAN. When the FRS fails, the objects are not replicated on the other
Domain Controllers. In the event of the primary DC failing, when the secondary (the slave) takes
over the request, it will not have the user account replicated. This will cause the log-on failure.
The replication failure can also occur because of incorrect DNS configuration.
Miscellaneous: There can be other reasons like no network connectivity, too many applications
accessing the DC at a time etc.
Active Directory monitoring with OpManager
OpManager monitors all the services and resources on which Active Directory relies for proper
functioning. You can configure thresholds and get instantly notified if something is crossing safe
limits.
Monitor domain controller’s availability
OpManager offers a dashboard view of your domain controller’s availability with options to see
availability statistics for the past week, month etc.
Monitor domain controller’s health
System resources usage gives you real-time status of the health of your domain controller.
Details such as CPU utilization, Memory utilization, and disc utilization can be viewed from here.
4. Monitor the performance counters
Active directory performance counters such as directory reads, directory writes, Kerberos
authentications etc can be viewed from here.
Monitor the Active Directory services
Key active directory services such as Windows Time Service, DNS Client Service, File Replication
Service, Inter-site Messaging Service, Kerberos Key Distribution Center Service, Security Accounts
Manager Service, Server Service Workstation Service, RPC Service, and Net Logon Service.
5. Complete list of active directory parameters monitored by
OpManager
Here’s a tree view of the entire set of parameters monitored by OpManager to ensure that your
Active Directory doesn’t popup unlikely surprises.

Monitoring active directory using event logs
Active Directory writes detailed event logs during failure. You can view event logs from your
Windows Event Viewer (start - settings - control panel- administrative tools - event viewer). Each
active directory component failure has a pre-defined event ID with a detailed message for the
failure event. OpManager allows monitoring these windows event logs using pre-defined event
log rules. OpManager monitors the event logs and based on the rule it generates OpManager
alarms.
Event Logs Monitoring for the Domain Controllers is configured as follows:
• Click 'Event Log Rules' on the right in the DC's snapshot page
• Scroll down to 'File Replication Service' and 'Directory Service' sections and select
the rules for the failures for which you want to be notified. The selected rules
will be associated to the devices.
Besides receiving alarms for the default rules, you can configure new rules for the
required Windows Event IDs.
7. Here are some IDs for which you might want OpManager to raise an alarm. (Please note that this
is only a subset of a whole lot of Windows Event Logs for various services and parameters
related to Active Directory.)
Service Event ID
Net Logon Service 5774, 5775, 5781, 5783, 5805
FRS Service 13508, 13509, 13511, 13522,
13526
Windows Time Service 13,14, 52 to 56, 60 to 64
LDAP related 40960, 40961
LSASS related 1000, 1015
Kerberos related 675, 676, 1002, 1005, 9004
(last three are related to
Exchange server)
NTLM authentication 680, 681
Instant notification from OpManager
Besides monitoring the Active Directory components, OpManager raises alarms when a service is
unavailable. Configuring response time or resource utilization thresholds for the critical services
and parameters alerts you much ahead of the actual problem. OpManager allows you to create
and assign notification profiles to Domain Controllers. When any of the monitors fail, an email or
SMS alert is sent to the pre-configured Ids.
