Dell EMC² MetroNode Capacity monitoring

It's necessary to enable automatic generation of capacity CSV files.
STOR2RRD uses CapacityClusters.csv generated by the storage as a main data source
Without that you won't see capacity statistics in the STOR2RRD UI. It is only the way how to get any capacity information from the storage.

MetroNode 7 and older

1. Set up automatic generation of capacity CSV files via VPlexcli on the first node of your MN cluster (where stor2rrd has allowed SSH read only access) via VPlexcli
   

   VPlexcli:/> schedule add "5 * * * *" "report capacity-clusters --verbose"
   

2. Check if the job was set properly (via VPlexcli)
   

   VPlexcli:/> schedule list
     [0] 5 * * * * report capacity-clusters --verbose
   

3. After an hour, check if the CSV file was automatically created (as stor2rrd user) with the recent timestamp
   

   stor2rrd@director-1-1-a:>; ll /var/log/VPlex/cli/reports
     -rw-r--r-- 1 service groupSvc  39347 Nov 23 12:05 CapacityClusters.csv
     -rw-r--r-- 1 service groupSvc 748435 Nov 23 12:05 CapacityClustersStorageVolumes.csv
     -rw-r--r-- 1 service groupSvc 557572 Nov 23 12:05 CapacityClustersVolumes.csv
   

4. When this is done, STOR2RRD automatically recognizes it and get capacity data from these files.
   

MetroNode 8

1. Navigate to /var/log/VPlex/cli/reports and create the generate_report.py file. Add t he following script to the file:

   service@director-1-1-b:/var/log/VPlex/cli/reports> cat generate_report.py
   #!/usr/bin/env python3
   from smsv2.jsonrpc_client import jsonrpc_request
   jsonrpc_request("yyapi", ["report capacity-clusters", "--verbose"])
   

2. Make the script executable by running the following command:

   chmod u+x generate_report.py
   

3. Open the crontab editor with the command crontab -e, and add the following line to run the script once per hour

   0 * * * * /var/log/VPlex/cli/reports/generate_report.py
