Free SAN and storage performance and capacity monitoring

Storage data sample rate

The tool had been supporting only 5 minutes data rate. Althought there were prepared configuration parameters for custom setup that they were ignored.

Since 1.31-7 (not public available yet as per Sep 2016) has been implemented even 1 minute data rate.
It is actually supported and tested only with IBM SVC/Storwize storages.
We planing to enhance it to Hitachi VSP G, HUS-VM and HPE 3PAR soon.

How to se it up? you have 2 possibilities:
  • Global setting for all storages (do not use it you you have other than 60sec supported storages)!
    vi etc/stor2rrd.cfg
  • Local setting only for particular storage (last "1" is sample rate in minutes)
    vi etc/storage-list.cfg
After that change you have to stop all svcperf processes and remove all already collected data.
Data files must be created from the scratch!
ps -ef | grep svcperf
  stor2rrd 16384120 1 0 17:20:25 - 0:03 /usr/bin/perl -w /home/stor2rrd/stor2rrd/bin/ storwize-home
kill 16384120
rm -r data/storwize-home
Now wait about 20 minutes, then run and you should see minute data in graphs
cd /home/stor2rrd/stor2rrd
Use zoom feature to check data granalurity.
