Debian 11 bullseye has been released in August and is now largely deployed. Will this patch be merged soon? There has been no release of this asset since nearly 2 years :-(

FWIW @GwennG I've largely moved over to the Sensu Golang-based equivalents to these monitoring-plugins also due to the lack of maintenance on this repo.

Ones like:

• https://bonsai.sensu.io/assets/sensu/check-cpu-usage
• https://bonsai.sensu.io/assets/sensu/check-memory-usage
• https://bonsai.sensu.io/assets/sensu/check-disk-usage

I've already switched most checks to other assets but I did not find any equivalent to some checks from this package.

I'm looking to prep a release for this so I'll be merging this in soon. But yes in general, if we can get golang replacements built it would be easier to maintain.

While its possible to maintain assets that involve runtime detected C libraries, its a significant burden to keep up with linux distribution targets.

statically compiled anything ends up being easier, hence the preference to build in golang if the intent is to have asset packages.
