metricbeat version 7.10.1 (amd64), libbeat 7.10.1 [v7.10.1 built 2021-02-02 03:16:09 +0000 UTC]
Hi,
According to the reference ([System memory metricset | Metricbeat Reference [7.11] | Elastic](https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-metricset-system-memory.html)) the memory metricset is available for FreeBSD.
However, when enabling it - you get the following error:
2021-03-05T16:40:58.220+0100 INFO module/wrapper.go:259 Error fetching data for metricset system.memory: VMStat: failed to read self process information: unimplemented
VMStat seems to be called from metricbeat/module/system/memory/memory.go#89 and declared in libbeat/metric/system/memory/memory.go#156
and imported from:
sysinfo "[github.com/elastic/go-sysinfo](http://github.com/elastic/go-sysinfo)"
sysinfotypes "[github.com/elastic/go-sysinfo/types](http://github.com/elastic/go-sysinfo/types)"
Looking at the go-sysinfo it seems this does not yet support FreeBSD: [GitHub - elastic/go-sysinfo: go-sysinfo is a library for collecting system information.](https://github.com/elastic/go-sysinfo)
Any chance we could fallback to sigar when OS is FreeBSD?
Thanks

In order to disable VMStat (as this won't work on a FreeBSD system) I changed the code as such:

memory is once again working for me 😉
