HWNPM2133W Performance data could not be collected for device device name due to an unknown error. 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 immediate operation of the running performance monitor is unaffected. However the next performance data sample recorded into the database might represent an average over more than the configured interval length.
Action
If the problem persists for an hour or longer, ensure that your device and device agent (if applicable) are operational, and that performance data collection is still enabled. Try cancelling and restarting the performance monitor job. If the problem is still not resolved, contact your IBM support representative.
