System/Performance feedback
Metrics works well with in containers but with some Olimex SBC I observe that data from pcp may be not found as in this issue or are not well dated as above.
My guess is that we may need to find a workaround the lack of good clock at early boot time and/or maybe a JS problem in cockpit code (unfortunately I still need to learn to debug with Firefox 
).
By the way, doing tests to try understanding, it seems that disabling Performance App may not suspend cron pcp associated tasks, if I notice correctly this may be a kind of bug.
And also:
munin samples
I am happy to run two Olimex LIME2 and recently intend to run a public Tor relay. Tor Relay Guide, Relay Post-install and good practices suggests munin that helps me as you may want to see 
I would like to make, with your help, munin as a FreedomBox available app.
Do you thing this could be planed ?
