If you've installed a Sumo Logic App and no data appears in an App's Dashboards, it could be due to an improper Source Category selection.
Apps are dependent on the Source Category metadata associated with your logs. This metadata is established when Collectors and Sources are configured. Because each organization uses their own metadata methodology, you may need to check with your Sumo Logic account's Administrator to get a better idea of which Source Category would be the best fit for a given app.
How can I change the Source Category associated with an app?
To change the Source Category used by an app, you can simply reinstall the same app. (Currently, apps cannot be uninstalled or edited in any other way.)
