Performance: Logging

The Grexx Platform Developer Tools include a number of overviews that you can use to monitor the performance of your application. To launch Developer Tools, open your application in any environment and press CTRL + ALT + S (on Windows) or CMD + ALT + S (on MacOS).

Active requests

The Active requests tab (available under Platform) displays the requests that Grexx Platform is currently processing. If your application has become unresponsive, you can use this to identify the cause. Equally, if multiple rows are displayed and/or the Started column shows that a request has been active for several minutes or more, there may be cause for investigation.

Performance

The Performance tab (available under Platform) lists all client-side requests (i.e. those made by the browser). The Total duration column shows how long each request took. Toggle to Error and slower than 5 seconds to filter the list to show long-running requests.

You can gain further insights by enabling additional columns. For example, a high value in the SELECT count column (available from the Columns pane) indicates that a dataset analysis might be useful.

API Requests

The API Requests tab (available under Platform) lists all server-side requests. The L2 duration column shows how long each request took. Toggle to Error and slower than 5 seconds to filter the list to show long-running requests.
