What’s New in System Center Operations Manager (SCOM) 2016?

Later this month, System Center Operations Manager (SCOM) 2016 along with the System Center suite and Windows Server 2016 will be available to the public. With that said, what’s new in SCOM 2016? Is it work the upgrade? etc., etc.

In previous posts, I did a walk-through on Maintenance Mode schedulesManagement Pack Updates, and how to integrate your SCOM environment with Operations Management Suite (OMS) go here for those.

While there isn’t exactly a change-log provided by Microsoft/System Center team(s), there is an article indicating the new features introduced in System Center Operations Manager SCOM 2016:

  • Management Pack Updates and Recommendations
  • Alert Data Management
  • Extensible Network Monitoring
  • Monitoring Nano Server and Workloads
  • Console User Interface Performance Improvements
    • HTML5 dashboards? Bye-bye Silverlight!?
  • Scalability Improvement with Unix/Linux Agents Monitoring
  • Maintenance Schedules
  • Extend Operations Manager with Operations Management Suite
  • Partner Program in Administration Pane

For the complete breakdown for what’s new in SCOM 2016, go HERE.

How to deploy OMS Agent on Linux

There are multiple ways how to deploy the OMS agent on your Linux server. In my post,  I am going to make use of GitHub and do a quick install on a Linux server.

In my environment, I am deploying the OMS Linux (Preview) agent (version 1.1.0-124) on a 64-bit Ubuntu server, version 14.04.4. Your Ubuntu server will of course need an Internet connection (directly or via Proxy). At the time of this post, the following Linux Operating systems are currently supported, and I am deploying the Linux agent version 1.1.0-124.

*image/source, Technet.Microsoft.com

Let’s get started…

Copy and save your OMS Workspace ID and Primary Key, as your OMS agent will need these to authenticate against. These can be found within your OMS Settings > Connected Sources:

Within your Ubuntu shell/terminal, you will need to execute the following three commands in order to download and install the OMS Agent. First we will download the latest OMS Agent from GitHub.

1

  • Followed by,
    • sha256sum ./omsagent-1.1.0-124.universal.x64.sh

2

  • Finally,
    • sudo sh ./omsagent-1.1.0-124.universal.x64.sh –upgrade -w <WORKSPACE ID> -s <WORKSPACE PRIMARY KEY>

If all goes well, you should now have an added server to your Connected Sources. Yay!

Very quickly, I can see my Ubuntu server is already transmitting data to OMS.

Like Windows servers, we can now start collecting data from the Syslog, collecting performance metrics in Near Real Time, and if your Linux box is deployed with Nagios and/or Zabbix, we can link this data into OMS too!

For additional information on configuring Linux Performance Counters, please visit the following page, HERE.

Lastly, don’t forget to add some important syslog OMS Data Log Collection, here is what I have configured:

Monitoring VMware (ESX/ESXi) with OMS

We all know monitoring Hyper-V and/or SCVMM with OMS is rather straight forward, and native. However, what about VMware (ESX/ESXi)?

In my VMware environment, I am using ESXi Host version 5.5 and vCenter version 6.0.

The following post is to help you monitor your ESX/ESXi environment with OMS.

  • First, you will need to enable the ESXi Shell, or SSH on your ESXi host, see HERE how
  • Next, you will need to configure the syslog(s) on your ESXi host, see HERE how

My ESXi server’s IP 10.10.10.30, and I will be forwarding the syslog(s) to my vCenter Windows Server IP 10.10.10.34. To be safe, I am going to configure both port 514 UDP and TCP .

ConfiguringSyslogOnESXiviaSSH

  • Remember to disable the firewall(s) on your vCenter Windows server
  • Now on your vCenter Windows Server, you will need to deploy the OMS Agent (Microsoft Monitoring Agent), see HERE how
    • Once your vCenter server is communicating with OMS, we can move on to the next step
  • Within OMS, if you haven’t already, you will need to enable “Custom Logs“; Settings > Preview Features > Enabled Custom Logs

EnableCustomLogs

  • Next, set up the following syslog file as your custom log on your vCenter server. In my case, my ESXi hostname is ‘RaviESXi’ and its IP is 10.10.10.30.
  • Followed by importing your syslog into OMS for the first time (see below for instructions)

C:\ProgramData\VMware\vCenterServer\data\vmsyslogcollector\yourESXiHostnameHere\syslog.log

For me, that path translates to, “C:\ProgramData\VMware\vCenterServer\data\vmsyslogcollector\RaviESXi\syslog.log

In my example, I then created an OMS custom log named “VMwareWin” for ESXi syslog. (By default, _CL suffix will be automatically added, which will result as, “VMwareWin_CL”) If you are unfamiliar with OMS’ Custom Logs, see HERE.

Once you have completed this step, it make take some time for your data to start showing up in OMS. Give it an hour or so…

  • Now we can start creating some custom fields within OMS. For example, ESXi Hostname, vmkernel, hostd, etc. See HERE about OMS’ custom fields in log analytics.
    • If you have done everything correctly, you should have custom logs and custom fields similar to this:

CreatingCustomLogs(2)

CreatingCustomFields

  • Now  you can start creating some dashboards with some custom queries!

For example, here’s one query I tested with and thought was worthy for its own dashboard:

All events and number of occurrences:

Type=VMwareWin_CL | measure count() by VMwareProp_CFDashboard1Example

Of course the number of queries and dashboards is endless at this point. Feel free to let me know your thoughts and some queries/dashboards you have come up with!

Lastly, don’t forget to add some important syslog OMS Data Log Collection, here is what I have configured:
