Watcher Field Value Based Alerts

Hi,

I have an app which returns different statuscodes based on URL being hit. I want to generate make a watcher alert based on the values in the same field with different outputs. I do not want the collective count/aggregated alerts. For example:

statuscode field can have values 220, 221, 222
the single alert should check each statuscode count separately
apply the threshold separately for each aggregated value
generate unique alert for each.

Currently I am using this which gives the collective count of each value. I want to separate the searched ctx.payloads.hits.total for each of the value

}

There are a couple of possibilities.

First, have a dedicated watcher for every status code. If you are using throttling/acknowleding alerts, then this probably makes most sense.

Second, keep using aggregations and have dedicated action for each statuscode, by using a condition as part of the action filtering for the status code.

Hope that helps as a start!
