Troubelshooting Tip: Discovery page showing blank in FortiSIEM
Description
This article describes how to resolve an issue where the Discovery page appears blank and configured discovery definitions are not visible in the GUI.
Scope
FortiSIEM.
Solution
When navigating to:
Admin > Setup > Discovery
The Discovery page may appear blank and no discovery definitions are displayed, even though discovery configurations exist in the system.
An investigation shows that a large number of stale discovery result files have accumulated under the following directories:
/data/cache/discoveryResults//data/cache/discoveryResults/locid//data/cache/discoveryResults/completed/
These directories contained many old XML files generated by previous discovery tasks.
To resolve the issue:
Stop the discovery-related processes, including phDiscover and Java process.
Review and stop any unnecessary background discovery schedules.
Make a backup and remove the stale discovery result files from the following directories:
/data/cache/discoveryResults//data/cache/discoveryResults/locid/Restart the discovery processes.
Refresh the GUI, log out, and log in again.
After clearing the stale discovery cache files and stopping the affected discovery processes, the Discovery page displays the configured discovery definitions correctly, and normal Discovery operations are restored.
