[gpfsug-discuss] Aggregating filesystem performance

[Brian Marshall]

All,

I have a Spectrum Scale 4.1 cluster serving data to 4 different client
clusters (~800 client nodes total).  I am looking for ways to monitor
filesystem performance to uncover network bottlenecks or job usage patterns
affecting performance.

I received this info below from an IBM person.  Does anyone have examples
of aggregating mmperfmon data?  Is anyone doing something different?

"mmpmon does not currently aggregate cluster-wide data. As of SS 4.1.x you
can look at "mmperfmon query" as well, but it also primarily only provides
node specific data. The tools are built to script performance data but
there aren't any current scripts available for you to use within SS (except
for what might be on the SS wiki page). It would likely be something you
guys would need to build, that's what other clients have done."


Thank you,
Brian Marshall
