The NFS plugins for Munin depend on the /proc filesystem in Linux for
|
|
|
|
|
statistics which does not exist in FreeBSD by default. While one can
|
|
|
|
|
add the linproc package to their installation to emulate this
|
|
|
|
|
functionality, I felt it would be better to write plugins that made use
|
|
|
|
|
of native tools.
|
|
|
|
|
|
|
|
|
|
I'm leveraging the nfsstat command to create these plugins. I'm sure
|
|
|
|
|
there is a better primary data source in FreeBSD to gather this output
|
|
|
|
|
from but for my purposes, using nfsstat is adequate and acceptable.
|
|
|
|
|
Unfortunately this means if the output of the nfsstat command changes
|
|
|
|
|
due to updates, these plugins will likely report inaccurate data.
|
|
|
|
|
These are the days of our lives, as they say. Someone with appropriate
|
|
|
|
|
levels of FreeBSD knowledge can probably improve these plugins
|
|
|
|
|
trivially.
|
|
|
|
|
|
|
|
|
|
I'm specifically targeting FreeNAS/NAS4Free, but the code should work
|
|
|
|
|
on any FreeBSD system with minimal package additions. Installing munin
|
|
|
|
|
on FreeNAS is not supported in general, but it's easy enough to do and
|
|
|
|
|
I wanted it monitored, ergo we are here.
