I would like to monitor the health of my HP ProCurve switches, but there is no dedicated sensor. Additionally, SNMP CPU and Memory don't work on the appliance. Any workaround?
Introduction
This works with the SNMP Custom Advanced Sensor, which allows you to query specific device OIDs within one sensor. In combination with the Lookups, this will give you the metrics you're looking for, nicely formatted.
The finished sensor, monitoring the Health of your ProCurve Switch
Installation
Remarks
- SNMP Sensors need to work in general on your appliance. Check out our SNMP Guide if you need to set this up first.
- You installed the Lookups at the end
Setup
- Create a new SNMP Custom Advanced Sensor on the device
- Configure the channels like in the below table:
| Name | OID | Value Type | Unit / Lookup |
|---|---|---|---|
| CPU Load | 1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0 | Gauge | CPU |
| Free Memory | 1.3.6.1.4.1.11.2.14.11.5.1.1.2.1.1.1.6.1 | Gauge | Bytes Memory |
| Fan State | 1.3.6.1.4.1.11.2.14.11.1.2.6.1.4.1 | Gauge | prtg.customlookup.hp.procurve |
| Primary Power Supply State | 1.3.6.1.4.1.11.2.14.11.1.2.6.1.4.2 | Gauge | prtg.customlookup.hp.procurve |
| Secondary Power Supply State | 1.3.6.1.4.1.11.2.14.11.1.2.6.1.4.3 | Gauge | prtg.customlookup.hp.procurve |
| Temperature State | 1.3.6.1.4.1.11.2.14.11.1.2.6.1.4.4 | Gauge | prtg.customlookup.hp.procurve |
| Average Temperature | 1.3.6.1.4.1.11.2.14.11.1.2.8.1.1.9.0 | Gauge | Temperature |
You're done! Apply some limits to the CPU Load / Memory channel. It should look something like in the screenshot.
