Since v4.50 you can monitoring HMC itself.
Following data is collected and graphed from all connected HMCs:
OS CPU utilization of user/sys/IO wait/idle in %
Memory utilization of used/fs cache/free memory in MB
Paging rate in MB/sec
You have to install v4.50 OS agent on the LPAR2RRD server.
If you run LPAR2RRD on Intel Linux then get agent rpm package from here:
Agent download (lpar2rrd-agent-4.XX-0.Linux.noarch.rpm)
You have to activate standard LPAR2RRD daemon
set: LPAR2RRD_AGENT_DAEMON=1 in etc/lpar2rrd.cfg
it gets started in the next LPAR2RRD run or manually by ./load.sh
Schedulle HMC data load from crontab:
0,5,10,15,20,25,30,35,40,45,50,55 * * * * . /home/lpar2rrd/lpar2rrd/etc/lpar2rrd.cfg; /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl -c localhost > /var/tmp/lpar2rrd-agent-hmc.out 2>&1
When is all set up then you will see graphs in menu --> HMC --> __YOUR_HMC__ --> CPU/Memory/Paging
Typical CPU/Mem/Paging usage on a HMC managing 4 x POWER7 servers with 100 LPARS:
