Cohesity DataProtect 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 collects preformance and configuration data from Cohesity using REST API.

Storage connectivity

  • Allow access from the STOR2RRD host to Cohesity’s nodes on port 443
            $ perl /home/stor2rrd/stor2rrd/bin/ 443
              TCP connection to "" on port "443" is ok
  • Create a new user for STOR2RRD with the Viewer role
    • Login to Cohesity GUI
    • Go to Settings -> Access management
    • Add Local User and assign “Viewer”
      Cohesity Storage management

  • STOR2RRD storage configuration

      Add storage device to configuration in the UI:
      Settings icon ➡ Storage ➡ New ➡ Vendor:device ➡ Cohesity : Cohesity DataProtect
      Cohesity Storage management

      Use Cohesity Cluster loadbalancing FQDN in STOR2RRD device configuration

    • Ensure you have enough disk space on the filesystem where STOR2RRD is installed
      You will need approximately 2 - 30 GB per storage system (it depends on the number of volumes - 30GB will cover 5000 volumes)
      $ df -g /home   # AIX
      $ df -h /home   # Linux
    • Schedule the storage agent in stor2rrd crontab (lpar2rrd on Virtual Appliance)
      Check there is no entry for Cohesity yet
      $ crontab -l | grep
      Add an entry if it doesn't exist
      $ crontab -e
      # Cohesity  
      0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/ > /home/stor2rrd/stor2rrd/load_cohesityperf.out 2>&1
    • Ensure there is an entry to build STOR2RRD UI every hour in the crontab
      $ crontab -e
      # STOR2RRD UI (just ONE entry of must be there)
      5 * * * * /home/stor2rrd/stor2rrd/ > /home/stor2rrd/stor2rrd/load.out 2>&1
    • Let the storage agent run for 15 - 20 minutes to collect data, then:
      $ cd /home/stor2rrd/stor2rrd
      $ ./
    • Go to the web UI: http://<your web server>/stor2rrd/
