Performance information is not displayed for a resource

Performance information is not displayed for a resource in performance views and charts.

Problem

For some resources and metrics, performance information is not displayed during a specific time range and resolution (granularity).

Action

If performance data is not being displayed for a resource and metric, one of the following situations might have occurred:
  • A performance monitor was never defined for the resource. You must run a performance monitor to collect and view performance data. To schedule a performance monitor, go to the resource list page, right-click a resource, and select Data Collection > Schedule.
  • A performance monitor was defined for the resource, but is not running. Accordingly, depending on when the most recent performance monitor completed, try adjusting the time range and data resolution on the performance view. You might need to change the data resolution to hourly or daily. Alternatively, start the performance monitor so that it can collect new data. To start a performance monitor, go to the resource list page, right-click a resource, and select Data Collection > Start Performance Monitor.
  • A performance monitor was defined and is running, but cannot collect any data. Check the values of Status and Latest Error (message) for the performance monitor on the Home > Performance Monitors page. To resolve some common problems, try the following actions:
    • Verify that the local area network is available and a firewall is not preventing network access to the resource and product services.
    • Verify that the resource you want to monitor is up and available.
    • If an SMI-S provider (CIM agent) is being used to communicate with the resource, ensure that the provider can be accessed, and is up and available.
  • None of the selected metrics is available. 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 (if used). Select different metrics to view performance data.
  • An internal component of Spectrum Control is not available or is down. To investigate the issue, try the following actions:
    • Check the status of the product servers and database repository on the Home > System Management page. In Component Servers, ensure that the servers are up and running. In Database, ensure that the database repository is up and running.
    • Check the log files that were generated for the internal components. External link iconLocation of log files.
  • For IBM Storage FlashSystem 900, SNMP is not enabled on the storage system. IBM Spectrum Control communicates with the SNMP agent on port 161 (UDP) to collect performance data.

    To enable the SNMP agent, open the management GUI of a storage system, go to Settings > Notifications > SNMP, click Agent, and enter a community name.
