Hi @<1673501397007470592:profile|RelievedDuck3>

how can I configure my alerts to be notified when the distribution of my metrics (variables) changes on my heatmaps?

This can be done inside grafana, here is a simple example:
None
Specifically you need to create a new metric that is the distance of current distribution (i.e. heatmap) from the previous window), then on the distance metric, create an alert
basically instead of the heatmap value, you take the current bucket value and subtract it from the same bucket X minutes ago

• create average over time per bucket, for example: histogram_avg(buckets_seconds[1d]))None
  2, then subtract two histograms and sum the abs difference
  sum(abs(buckets_value - histogram_avg(buckets_value[1d])))
  None
  None
