[gpfsug-discuss] Gathering node/fs statistics ?

[Jan-Frode Myklebust]

I'm considering writing a Performance CoPilot agent (PMDA, Performance
Metrics Domain Agent) for GPFS, and would like to collect all/most of
the metrics that are already available in the gpfs SNMP agent -- ideally
without using SNMP..

So, could someone help me with where to find GPFS performance data? I've
noticed "mmfsadm" has a "resetstats" option, but what are these stats /
where can I find them? All in mmpmon?

Also the GPFS-MIB.txt seems to point at some commands I'm unfamiliar
with:

	-- all other node data from EE "get nodes" command
	-- Status info from EE "get fs -b" command
	-- Performance data from mmpmon "gfis" command
	-- Storage pool table comes from EE "get pools" command
	-- Storage pool data comes from SDR and EE "get pools" command
	-- Disk data from EE "get fs" command
	-- Disk performance data from mmpmon "ds" command:
	-- From mmpmon nc:


Any idea what 'EE "get nodes"' is? And what do they mean by 'mmpmon
"gfis"', "nc" or "ds"? These commands doesn't work when fed to mmpmon..
