This repository contains a Powershell script sensor for Paessler PRTG which allows you to monitor the health of Aruba switches with ArubaOS-CX operating system (6000 series, 8000 series).

The sensor allows you to monitor the following parameters of individual switches and VSF stacks as well as members of VSX stacks

• Current usage of PoE budget per Switch in percent
• State of power supplies in percent
• State of fan trays in percent
• highest currently measured CPU temperature (of all chassis in the stack)
• highest currently measured intake temperature (of all chassis in the stack)

The script uses the REST API 10.08 of the ArubaOS-CX switches. It is therefore necessary that the switches to be monitored have at least version 10.08.

To install the sensor, copy the files (AOS-CX folder and AOS-CX-Sensor.ps1) to the PRTG Network Monitor\Custom Sensors\EXEXML folder on your PRTG core server and remote probes that are supposed to use the script sensor.

The Windows login data for the device set in PRTG is passed to the script as environment values.

In order to use the REST API of a ArubaOS-CX switch, the web server must be enabled in the VRF, which is used to access the switch from PRTG. Additionally, a password must be set for the admin user to enable the API feature.

# access via default vrf
https-server vrf default

# access via OOB management port
https-server vrf mgmt 

# access-mode can be set to readonly
https-server rest access-mode read-only

# (optional, but recommended) add a separate monitoring user 
user monitoring group operators password plaintext <securepassword>

The API credentials must be stored in the Windows credentials of the device (or inherited to the device via the group).

In the PRTG sensor settings, the "Environment" setting must be set to "Set placeholders as environment values" so that the switch hostname/IP address and windows login data is passed to the script as environment variables.

For a VSF stack only one sensor needs to be added, VSX stacks need to be monitored individually (one sensor per device).
