When creating an Alarm tab page in the alarm console, use Filter to create a tab page.
If you try to add Severity durations with the Add column function, the Severity durations column does not exist.
I would like to ask if the "Severity duration" column is not available when using Filter.
The severity duration is a column value that is calculated in the client application, while the filter defined in your custom tab filter is a filter that is sent to the server.
And while I know a user doesn't really care about those details, it's important to know in this case. Because if we allow filters that are done client side alongside the others, 2 things will happen:
- The server would need to send ALL of the alarms, causing a lot of bandwidth usage
- The client would then need to filter them afterwards, causing a slower user experience overall.
There is currently no way to do client side filtering with other operators than (not) equal, although I do admit it's an interesting feature idea.
