New Monitor: remote queries via ssh

wsw70 commented 4 months ago

This is a preliminary PR for a new Monitor that uses SSH to connect to a remote machine, run a command, parse it results to extract a value which is then monitored.

Why preliminary?

it is fully working but since the paradigm is different than other monitors I am looking for comments and ideas for changes. A RFC of sorts.
it uses match which is a Python 3.10+ feature. I will make it retro-compatible with 3.7 as a new branch when this PR is tested/reviewed, awaiting for Simplemonitor to be, someday, bumped to 3.27 (EBV - Expected Bump Version)
I have it working for some time already with various systems and, well, it works. But YMMV. And I want to know typical mileages to account for them in the code.

Important note for @jamesoff : I had to change in envconfig.py ConfigParser to RawConfigParser otherwise the regex I read in was escaped (see the commit). I do not think it changes anything because as far as I could tell you do not rely on escaping when reading the configuration.

So try it out (git checkout monitor_remote_ssh) and let me know!

Thanks! I'm away until next week so won't be able to take a proper look at this until then - I'm not ignoring it :)

I just bumped the version of parakimo on the develop branch btw (finally merged dependabot's PR)

I'm fine with the change to ConfigParser, don't think that will cause any issues.
