Due to the poor performance at scale of the windows checks and metrics included in the sensu community repo, I've written ones that run in about a quarter of the time, without the large CPU hit.
All metrics live in a single script to stop spawning as many powershell instances. The output is Influx line protocol.
This has only been tested on server 2008/2012 R2 with powershell-core (powershell 6)
