Grafana Alerts: different conditions for different labels?

Assuming I have a counter with 3 different labels, how can I create an alert with a different condition for each of the labels, without splitting the query into 3?

So instead of 3 queries like this:rate(my_counter{mylabel=1}[30s]) I’d like to use just a single query: rate(my_counter[30s]), and create different conditions for mylabel=1, mylabel=2, mylabel=3. Is it possible?

Grafana v7.1.5 (9893b8c53d)

You can use a regex match (=~ instead of =) to match all three of the
values in a single query.

Thank you but it's not what I meant (I think). To make it clear, what I meant is instead of this:

I'd like to do something like this:

In the first one I separate the conditions by query, and in the second one I want to separate by label value. Is this possible?

That sounds like a Grafana specific question, so while there are
probably some people on this mailing list who might know I'd also
suggest posting to one of the Grafana lists...

In the meantime I posted to community.grafana.com . What are the Grafana lists?

Hello, You can store your thresholds in a metric that has the same values of that label, that way you can compare on that label in only one query, look at this https://www.robustperception.io/using-time-series-as-alert-thresholds

Thank you, but how can I implement this in Grafana?
