After working with SNMP for quite a while we’ve repeatedly run into issues
where monitoring software is unable to accurately determine the utilization
of volumes on some Linux partitions due to regular processes being unable
to access the reserved file space. I believe that the best way to correct
this issue is to include an additional data point in the Host Resources MIB
(RFC2790) that will return available space. This should have no negative
impact on systems that do not utilization reserved space, but will allow
for a much more accurate picture of the space that is truly available on
those partitions using reserved space.
I’ve been reading through the IETF site a bit, but I’m still not sure as to
the best process to get this implemented. I was hoping someone on here
could give me some tips on proceeding with this. From what I can see, I
just need to update RFC2790 with the below information and resubmit.
RFC 2790
Add:
hrStorageAvail OBJECT-TYPE
SYNTAX Integer32 (0..2147483647)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
“The amount of the storage represented by
this entry
that is available to non-superusers, in
units of
hrStorageAllocationUnits.”
::= { hrStorageEntry 8 }
Thanks,
Sheppy Reno
