Splunk Lantern

Monitoring VMware virtualization infrastructure

Scenario: You work in the IT department for a large software development company that makes heavy use of virtual machines for testing during development.

It is crucial that the virtual machines that rely on the VMware ESXi hypervisor and vSphere remain available so that the software release cycle isn't disrupted. Part of your job is to monitor all VMware infrastructure and respond to any issues that might arise.

You can use Splunk software to monitor virtual machine and virtual machine host resource usage, watch for key events that might require troubleshooting, and obtain useful inventories of your VMware environment.

Prerequisites  

To succeed in implementing this use case, you need the following dependencies, resources, and information.

How to use Splunk software for this use case

You can run many searches with Splunk software to monitor VMware virtual machine performance. Depending on what information you have available, you might find it useful to identify some or all of the following: 

Results

To maximize their benefit, the how-to articles linked in the previous section likely need to tie into existing processes at your organization or become new standard processes. These processes commonly impact success with this use case: 

  • Capacity planning, compute hardware, storage, and network 
  • Native monitoring tools integrated with Splunk for cross-domain visibility
  • Tooling for software provisioning and configuration management
  • Backups, security, and compliance

Measuring impact and benefit is critical to assessing the value of IT operations. The following are example metrics that can be useful to monitor when implementing this use case:

  • Mean time to problem resolution 
  • Mean time to root cause analysis
  • Reduction in system degradation, such as underperformance or unplanned downtime

Additional resources 

This use case is also included in the IT Essentials Learn app, which provides more information about how to implement the use case successfully in your IT maturity journey. In addition, these Splunk resources might help you understand and implement this use case:
