Tracked Files Tab is hidden in Pattern Designer, after enabling system property glide.discovery.enable_file_tracking.

The "Tracked Files" Tab will only be displayed if the Pattern is already set to be triggered directly by a Classification.

For example:

• "Windows OS - Servers" pattern displays it because it is triggered by the "Windows 2019 Server" Windows Classification.
• "Apache on UNIX based OS" pattern displays it because it is triggered by the "Apache Server" Process Classification.
• "F5 Load Balancer" pattern displays it because it is triggered by the "F5 BIG-IP Load Balancer" SNMP Classification, which is used due to the SNMP OID Classifications for F5.
• "F5 BigIP GTM" pattern doesn't display it, because this isn't triggered as part of Horizontal Discovery. This is a Service Mapping pattern.

Only the discovery_classifier_probe records that reference the pattern are taken into account. If none exist, the tab is not shown.

You will need to save a new custom pattern, and configure a classification to trigger it, before you can re-load the pattern designer and see the tab.

If the Pattern is not designed for Horizontal Discovery, then you should not trigger it using a horizontal discovery Classification, and so you'll not expect to see the tab.
