Missing Usage Viewer and System Assessment data

Pega Predictive Diagnostic Cloud™ (PDC) gathers hourly usage information from monitored systems to create usage and system performance statistics that are divided by requestor type and by application. You can view these statistics on the Usage Viewer and System Assessment landing pages. If the agent that sends this information stops running, or if sending the usage tracking information is disabled in your application configuration, PDC does not display the usage and system performance information.

Symptoms

On the Usage Viewer and System Assessment landing pages, usage data is missing and a warning banner informs you either that an agent that feeds data to PDC is not running, or that the configuration setting for usage tracking is disabled.

The following warning banners are displayed:

  • Warning. The Agents Push Hourly/Daily Log Usage Data agents that feed usage data to PDC is not running.
  • Warning. The usage/usagetrackingenabled setting is disabled. Enable it to feed usage data to PDC.

Explanation

This error might occur in the following circumstances:

  • When the agents that send hourly and daily log usage information are not running. For example, the agents were stopped or disabled manually or because of an exception.
  • When usage tracking in your application is disabled.

Solution

Use the following approach to troubleshoot and resolve the usage tracking agent issues.

  • If you see a warning about agents that are not running correctly, verify the status of the agents that send hourly and daily log usage information:
    1. In the PDC navigation pane, click System Resources > Agents.
    2. In the Agent details section, search for the Push Daily Log Usage Info agent and for the Push Hourly Log Usage Data By App Info agent.
    3. Expand the agent, and then check whether it is running on all nodes.
    4. In the Agent details section, search for the Push Hourly Log Usage Data By App Info agent.
    5. Expand the agent, and then check whether it is running on all nodes.
    6. If at least one of the agents is not running correctly, start that agent. For more information, see Managing agents.
  • If you see a warning about disabled usage tracking, check your application settings:
    1. In the PDC navigation pane, click System Resources > Nodes.
    2. In the Node details section, expand any of the util nodes, and then click Configuration setting info.
    3. Search for the usage/usagetrackingenabled setting, and then verify that the setting is set to True.
    4. If the setting is set to False, or if the setting does not exist in your application, contact Pega Support, and then request enabling usage tracking for your application.
