Displaying match result only

[alicemara]

I am trying to figure out a good way to only show values of a field that matches a filter in a jira alert.
I'm looking for all results on a wildcard filter that's formatted like "email: *domain.com"

So if I had three matches aggregated over a day, I would hopefully end up with something like this in the body:

[email protected]
[email protected]
[email protected]

The closest I've gotten is:

alert_text: "{0}"
alert_text_args:
- email

The above txt will give me the match, but then follows it with the json of the the entire doc the match is part of.
I have tried with alert_text_type: alert_text_only as well, but that only shows the first result.

Any suggestions are highly appreciated!

Have you tried using the summary_table_fields setting? There's some additional documentation on this under the Aggregation configuration setting.

I had tried the summary_table_fields, but had missed the aggregation_key option, which looks like it's exactly what I am looking for. Thank you so much!
