HWNPM2150W Performance data could not be collected for device device name, because of an unresponsive target. 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. The problem is an unresponsive target. This condition can occur when the target server is powered off, or when the server is not listening on the port which is the target of the communication (for example if the web server or CIMOM is not operational). This type of failure can usually also be idenfied via a java.net.ConnectException printed in the trace logs.
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.
