Free Storage, SAN and LAN Performance and Capacity Monitoring

FreeNAS, TrueNAS

Back to storage installation home.

In case of usage of Virtual Appliance
  • Use local account lpar2rrd for hosting of STOR2RRD on the virtual appliance
  • Use /home/stor2rrd/stor2rrd as the product home
STOR2RRD uses REST API interface natively provided by the storage to get all necessary data.

It is not released yet (expected release Jan 2020 with next STOR2RRD release).
If you want to try it let us know via support@stor2rrd.com.


Storage connectivity

  • Allow access from the STOR2RRD host to the storage on port 443 (80 in case http)
    $ perl /home/stor2rrd/stor2rrd/bin/conntest.pl 192.168.1.1 443
      Connection to "192.168.1.1" on port "443" is ok
    
  • Storage user: root account must be used, unfortunately only root can connect REST API.

STOR2RRD storage configuration

  • Add storage into configuration from the UI:
    Settings icon ➡ Storages ➡ New ➡ Vendor:device ➡ iXsystems : FreeNAS
    Storage management

  • Assure you have enough of disk space on the filesystem where is STOR2RRD installed
    Roughly you might count 2 - 30 GB per a storage (it depends on number of volumes, 30GB for 5000 volumes)
    $ df -g /home   # AIX
    $ df -h /home   # Linux
    
  • Schedule to run storage agent from stor2rrd crontab (lpar2rrd on Virtual Appliance, it might already exist there)
    $ crontab -l | grep load_freenasperf.sh
    $
    
    Add if it does not exist as above
    $ crontab -e
    
    # FreeNAS, TrueNAS  
    0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/load_freenasperf.sh > /home/stor2rrd/stor2rrd/load_freenasper.out 2>&1
    
    Assure there is already an entry with the UI creation running once an hour in crontab
    $ crontab -e
    
    # STOR2RRD UI (just ONE entry of load.sh must be there)
    5 * * * * /home/stor2rrd/stor2rrd/load.sh > /home/stor2rrd/stor2rrd/load.out 2>&1
    
  • Let run the storage agent for 15 - 20 minutes to get data, then:
    $ cd /home/stor2rrd/stor2rrd
    $ ./load.sh
    
  • Go to the web UI: http://<your web server>/stor2rrd/
