maxcache monitoring

[arekm]

Feature request about monitoring of maxcache status. It's a cache that uses SSD disks.

Probably it's enough to monitor this part:

NOT PARSED: [maxCache 3.0 information] [   Status of maxCache                       : Optimal] at /usr/share/perl5/vendor_perl/App/Monitoring/Plugin/CheckRaid/Plugins/arcconf.pm line 263, <$fh> line 1179.

and maybe

NOT PARSED: [maxCache 3.0 information] [   Failed stripes                           : No] at /usr/share/perl5/vendor_perl/App/Monitoring/Plugin/CheckRaid/Plugins/arcconf.pm line 263, <$fh> line 1185.

hi, I've bumped into the same issue, the NOT PARSED lines are coming from the arcconf GETCONFIG 1 AL exec, here is the relevant output(the full output is fairly large, 11598 lines):

[glensc]

please include ALL output, do not truncate at your will. will be used to seed tests. see CONTRIBUTING.md

[Tyrael]

I've seen the CONTRIBUTING.md but pasting 16k lines which mostly irrelevant sounds bad.
I can look into cooking up a pull request if that's easier for you.

[glensc]

the point of the output is that when changes are made to code-base, existing systems can stay working. for example parser is changed. you can't possibly predict which information is relevant or not. you may obfuscate values of course. you may think omitting repeated values can be omitted, but then different output is related together you create broken relations if you did not account that value X in block A may be related to value Y in block B.

In above

looks weird. Shouldn't be that some "cat /proc/mdstat"?

Anyway back to the issue:
