We had a customer contact us via a support ticket about a similar issue.
In this particular case, the monitored device did not provide all the OID's required by the sensor. And this results in the error. We'd recommend anyone encountering this issue to first of all update the device's firmware to the latest version and then deleting and re-creating the sensor.
Background:
For temperatures, we need three distinct OID's:
- 1.3.6.1.4.1.9.9.13.1.3.1.2.index Temperature Descr
- 1.3.6.1.4.1.9.9.13.1.3.1.6.index Temperature State
- 1.3.6.1.4.1.9.9.13.1.3.1.3.index Temperature Value
With this particular case/customer, the Temperature Value readings were missing, which caused the sensor to fail..
Don't hesitate to contact us if you encounter a similar issue so that we can confirm the precise cause.
Best Regards,
Luciano Lingnau [Paessler Support]
