Need some help configuring performance monitoring for your storage systems and switches?
Find solutions to common problems that you might encounter when using IBM
So, you've followed the instructions in Moni
But your performance charts are still not showing up to date performance metrics for your storage.
Help is at hand. Let’s take a look at some of the common problems and suggest some possible solutions.
A performance monitor was defined for the resource, but is not running
Start the immediate collection of performance data from the monitored resource. A successful probe must be completed on the resource before a performance monitor can start.
Go to the resource list page. For example, for block storage, go to Storage > Block Storage Systems. Right-click your storage system and click Data Collection > Start Performance Monitor.
On the resource list page, you can also check the performance monitor status and the most recent date when the performance monitor successfully collected data. Depending on when the performance monitor last ran successfully, try adjusting the time range and data resolution on the performance view. You might need to change the data resolution to hourly or daily.
A performance monitor was defined and is running, but cannot collect any data
Try the following actions:
Right-click the performance monitor row and click Open Logs. You can view detailed informational, warning, and error messages that are related to the performance monitor job. In the log, click on a message ID to view recommended actions to help you troubleshooting the error or warning.
A problem with the database or product servers is preventing the collection of performance data
Try the following actions:
If the system management overview shows the component servers with an error status, click Component Servers to view detailed server information and to restart the Data, Device, or Alert server.
Similarly, if the overview shows that the database has an error status, click Database to view detailed information, such as the memory usage, capacity, and version of your Db2 instance.

The performance chart is not showing values for the selected metrics
The selected metrics might not be available for the resource.
The metrics that are available for a resource are determined by a number of factors, such as the type of resource, release version of a resource, and level of SMI-S provider. For example, some SAN Volume Controller metrics are available only to storage systems whose firmware version is 7.3 or later.
For a list of performance metrics that are available for the different storage systems and switches, check out the Performance metrics section in the knowledge center.
