Enterprise Level Monitoring with SCOM and Splunk

Posted by Sandeep Chanda on Aug 25, 2014

Enterprise monitoring needs over the years have been addressed by Microsoft Systems Centre Operations Manager to a large extent. The problem however is that SCOM produces a lot of noise and the data could very quickly become irrelevant for producing any actionable information. IT teams very easily fall in the trap of configuring SCOM for every possible scheme of alerts, but do not put effective mechanisms in place to improve the alert to noise ratio by creating usable knowledge base out of the alerts that are generated by SCOM. Splunk and its cloud avatar, Hunk could be very useful in the following aspects:

  1. Providing actionable analytics using the alert log in the form of self-service dashboards
  2. Isolation of vertical and horizontal monitoring needs
  3. Generating context around alerts or a group of alerts
  4. Collaboration between IT administrators and business analysts
  5. Creating a consistent alerting scale for participating systems
  6. Providing a governance model for iteratively fine tuning the system.

In your enterprise, Splunk could be positioned in a layer above SCOM, where it gets the alert log as input for processing and analysis. This pair can be used to address the following enterprise monitoring needs of an organization:

  1. Global Service Monitoring - Provides information on the overall health of the infrastructure, which includes surfacing actionable information on disk and CPU usage. It could also be extended to include the network performance and the impact specific software applications are having on the health of the system. Splunk will augment SCOM in creating dashboards from the data collected that could help make decisions. For example, looking at the CPU usage trends on a timeline, IT owners can decide increasing or decreasing the core fabric.
  2. Application Performance Monitoring - Splunk can be extremely useful in making business decisions out of the instrumentation you do in code and the trace log it generates. You can identify purchase patterns of your customers. The application logs and alerts generated by custom applications and commercial of the shelf software (COTS) could be routed to Splunk via SCOM using the management packs. Splunk can then help you create management dashboards that in-turn will help the executive team decide the future course of business.

Using Splunk in conjunction with SCOM provides you a very robust enterprise monitoring infrastructure. That said, the true benefit of this stack can be realized only with an appropriate architecture for alert design, a process guidance on thresholds, and identification of key performance indicators to improve the signal to noise ratio.
