Hello,
We are just diving into using collectl to monitor out lustre filesystems
and compute nodes. For the time being we just have our lustre data going
into graphite collector on an vmware VM. It is working well and has
already helped us identify some problems with our filesystems.
I would like to start collecting slab summary info
(/slab,InUse,Avail,SizeK,Number,UsedK,TotalK,Change,Pct) for our mds
servers and send this to graphite but it is not working as I expect.
We are running collectl as a service using this for our /etc/collectl.conf
DaemonCommands = -f /var/log/collectl -P -sy --export graphite,172.23.0.53
-r00:00,7 -m -F60 -s+YX
This does not populate slab info in our graphite server. the command
collectl -sy works
mds1:~ # collectl -sy
waiting for 60 second sample...
# SLAB SUMMARY
#<------------Objects------------><--------Slab
Allocation-------><--Caches--->
# InUse Bytes Alloc Bytes InUse Bytes Total Bytes InUse
Total
9167806 2966M 10079K 3146M 778419 3228M 778573 3229M 111
204
What should I put in /etc/collectl.conf to gather this information in
addition to what I am already grabbing?
mds1:~ # collectl -v

Thank you and thanks for the software, very useful.
