In a Prometheus timeseries database, there are two sets of data (for M1 and M2) collected with following schema
Write a PromQL query that creates a new time-series N, that tracks the max(M1, M2) for each time period the query is run.
I tried using max(), but it takes only 1 argument.
PromQL allows selecting time series with multiple different names via regexp filter on __name__
pseudo-label. See these docs. For example, the following query selects all the series with names m1
and m2
:
{__name__=~"m1|m2"}
So, the following query would select the max values over all the series with names m1
and m2
per each requested timestamp:
max({__name__=~"m1|m2"})
