Free Storage, SAN and LAN Performance and Capacity Monitoring

Storage data sample rate

The tool supports only 5 minutes sample rate for storage and SAN devices.
Whatever else setup in configuration files is ignored.

Since version 1.35 has been implemented 1 minute data rate but only for IBM SVC/Storwize/FlashSystem storages.

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_alias
kill 16384120
rm -r data/storwize_alias
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.
