Events Event Limit is counterintuitive, throws a system error

[drewmiranda-gl]

Graylog Events using "Filter & Aggregation" Condition Type have 2 options for 'Create Events for Definition if...'

1. Filter has results
2. Aggregation of results reaches a threshold

When using 'Filter has results', you are now REQUIRED to specify an event limit, between 1 and 1000. Once this limit is reached (not exceeded) a Graylog system alert is generated:

Event limit »1« reached for event definition »EventDefinitionTitle(<Event_definition_id>)«. Try to use a more specific search query or use aggregations. Otherwise try to raise the limit.

However this is confusing for a couple of reasons:

• you are not allow to remove this limit (technically you can edit the event definition and set the limit to 0 but this is not a good idea)
• This is the only way to control how many events get generated and preventing a flood of events (which is this features original intent)

This is to say, its 100% expected that this event limit will be reached. I don't think a system alert should be generated and the advice it gives is counter to the intended outcome.

Expected Behavior

Using Event limit as its intended should not throw a system alert

Current Behavior

Once the event limit is reached (even if the limit is set to 1 and 1 message is returned), a system event is generated.

Possible Solution

Remove this system alert, or at least allow the user to disable it either globally or per event.

Steps to Reproduce (for bugs)

1. Create a "Filter & Aggregation" event
2. Set 'Create Events for Definition if...' to 'Filter has results'
3. Set limit to 1
4. Allow event to fire

Context

Attempting to create a simple event that fires if the search query is met and prevent more than a single event from being created. This generated a system event which is not actionable and technically not solvable other than changing 'Create Events for Definition if...' to 'Aggregation of results reaches a threshold' which is the workaround i will use.
