Troubleshooting- Hewlett Packard devices - Invalid Certificate

Context

It occurs that some Hewlett Packard devices are unreachable.

However, we can verify that the Focalist Agent is installed and connected.

Cause

The Agent cannot access the HP device web page (EWS) due to an invalid certificate. This is used to read counters with the default policy HP_FUTURE_SMART.

Resolution

It is advisable to proceed to a meter reading in pure SNMP by changing the strategy to HP_LASERJET_ACCOUNTING.
