Qumulo 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 is using Qumulo API to access performance statistics and configuration data.
API is accessible over HTTPS port 8000 on Static as well as Floating IP addresses.

Storage connectivity

• Allow access from the STOR2RRD host to the Qumulo storage on port 8000
  

  $ perl /home/stor2rrd/stor2rrd/bin/conntest.pl 192.168.1.1 8000
    Connection to "192.168.1.1" on port "8000" is ok
  

• Create user for STOR2RRD
  Log in to Qumulo management GUI
  Go to Cluster -> Local Users & Groups
  Note: since Qumulo 3.0.5 and higher you have to manually assign Observers role to STOR2RRD user
  Create new user in group Users

STOR2RRD storage configuration

• Add storage into configuration from the UI:
  Settings icon ➡ Storage ➡ New ➡ Vendor:device ➡ Qumulo
  
  
• 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_qumuloperf.sh
  $
  

  Add if it does not exist as above

  $ crontab -e
  
  # Qumulo
  0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/load_qumuloperf.sh > /home/stor2rrd/stor2rrd/load_qumuloperf.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
