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
    FreeNAS 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_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/
