Description

Use Case

Currently using [[inputs.vsphere]] to get data from vSphere and output them to influxDB using [[outputs.influxdb_v2]]. Then using Grafana to visualise the data. As far as I can see, currently, no metric(s) get VM snapshot data. This feature request is to see if it's possible to pull VM snapshot information via the [[inputs.vsphere]] plug-in, so this information can be visualised via Grafana.

Expected behavior

VM snapshot data is collected via the [[inputs.vsphere]] plug-in

Actual behavior

Currently this not happening

Additional info

Telegraf version 1.32.1 InfluxDB version 2.7.10 vSphere vCenter version 8.0.2.00200

The request is similar to #7741, but I'm not looking for specific storage usage, only to see if a snapshot exists and the age or the time the snapshot was created.

Research direction
Examine the existing vsphere input plugin at plugins/inputs/vsphere/ to understand how other metrics are collected. Check the vSphere API documentation for snapshot related properties (e.g., snapshot.currentSnapshot, snapshot.createTime). Look at issue #7741 which requested similar functionality for storage usage. The implementation would likely involve adding a new metric collector that queries snapshot information and adds it to the measurement.
