ESXi host version identification
A report of the versions of VMWare ESXi actively running within your virtualization environment can help you identify version inconsistencies or older versions in need of upgrade.
- 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.
- Ensure that you have installed the IT Essentials Work app to onboard VMware data and provide the various VMware entity type configurations and dashboards.
- 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.
- 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
The table provides an explanation of what each part of this search achieves. You can adjust this query based on the specifics of your environment.
|| mcatalog values(os_version) AS esxiversion WHERE index=vmware-perf-metrics AND entity_type=vsphere.esxihost BY name||
Search VMWare metric indexes for ESXi version values by ESXi host.
| dedup name sortby - _time
Remove duplicate ESXi hosts from the results.
|| stats count BY esxiversionmoid="*"||
Provide a count of the results, sorted by version ID.
Upgrade versions as needed.
