HWNPM2151W Performance data could not be collected for device device name, because a communication time-out for communication that uses UDP rather than TCP. The current samples are skipped.
Explanation
The current attempt to retrieve a set of performance data from the device failed. No performance data will be inserted for the device in this time period. The next performance data sample recorded into the database might represent an average over more than the configured interval length. This condition can occur when the target server cannot be reached, or when the SNMP data source is disabled on the target server, or when the SNMP port (161) is blocked by a firewall.
The immediate operation of the running performance monitor is unaffected.
Action
If the problem persists for an hour or longer, ensure that your device and device agent (if applicable) are operational. Also ensure that a network path exists between the TPC server and the device or device agent, including any appropriate firewall pass-throughs. If there is nothing wrong with the device or device agent, or with the network path, try cancelling and restarting the performance monitor job. If the problem is still not resolved, contact your IBM support representative.
