ESXi host version identification

Data required

• VMware. This procedure depends on data primarily obtained from the Splunk Add-on for VMware Metrics; however, log and event data from the VMWare environment can also provide additional insights into general VMWare environment health. Therefore, for best performance, you should also download and install Splunk Add-on for VMware ESXi Logs and Splunk Add-on for vCenter Logs.

Procedure

1. Ensure that you have installed the IT Essentials Work app to onboard VMware data and provide the various VMware entity type configurations and dashboards.
2. Ensure that you are collecting VMware data through one or more Data Collection Nodes, which are essentially Splunk heavy forwarders with specific VMware collection configurations.
3. Run the following search. You can optimize it by specifying an index and adjusting the time range.

| mcatalog values(os_version) AS esxiversion WHERE index=vmware-perf-metrics AND entity_type=vsphere.esxihost BY name
| dedup name sortby - _time
| stats count BY esxiversion
