PRTG-PureStorage

You can use this script to monitor some essential information about your PURE storage system using PRTG EXE/Advanced sensor. For this to work you need to install the PURE PowerShell module from PSGallery onto your PRTG probe using the following command:

Install-Module -Name PureStoragePowerShellSDK

As PRTG runs in 32-bit environment (even on 64-bit Windows installation), be sure to install the module in 32-bit PowerShell, else it will not work.

After installation is complete, save this script to the Custom Sensors\EXEXML file on your probe servers. Now create a new *EXE/Advanced" sensor and select the PowerShell file you just saved from the dropdown. You need to provide two parameters:

  1. StorageAddress This is the IP address or hostname of your PURE storage system, which can be fetched from the parent object in your PRTG tree using the variable %host
  2. ApiToken Instead of providing a username and password, you can retrieve an API token for a user account (READ access to PURE is sufficient) from your PURE storage webconsole. Use this token here to authenticate the scripts requests.

Example: -ApiToken "abcde-a9d7a87-000000" -StorageAddress %host

The sensor will provide the following channels:

  1. Hardware ok count The script retrieves the count of devices that report the status ok.
  2. Hardware not installed count This is the number of devices, reporting not installed.
  3. Hardware NOT ok count Every other hardware state except for OK and NOT INSTALLED will be counted here.
  4. Volumes (Bytes Reports the size in TB assigned to volumes in the PURE storage system.
  5. Total used space (Bytes) is the really occupied storage on the system.
  6. Total sorage capacity (Bytes) represents the total capacity of the system. This value should only change, if there is a hardware extension.
  7. Free space (Bytes) shows the total capacity reduced by the total used storage in TB.
  8. Free space (%) The free space in percent.
  9. IOPS - Writes/sec shows the current write operations per second.
  10. IOPS - Reads/sec shows the current read operations per second.
  11. Write latency (ms) represents the time in milliseconds, the write IO currently takes.
  12. Read latency (ms) represents the time in milliseconds, the read IO currently takes.
