FreeNAS and TrueNAS monitoring

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 FreeNAS REST API interface natively provided by the storage to get all necessary data.
Supported are FreeNAS firmwares 11.2+.

Storage connectivity

• Allow access from the STOR2RRD host to the FreeNAS 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 FreeNAS REST API.

STOR2RRD storage configuration

• Add storage into configuration from the UI:
  Settings icon ➡ Storage ➡ New ➡ Vendor:device ➡ iXsystems : FreeNAS
  
  
• 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_freenasperf.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/
