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