Subject: [prometheus-users] Re: How to define metric type as a variable
No, because binary operators like division are designed to work between
different metrics (with the same set of labels, but different metric name), e.g.
node_filesystem_avail_bytes / node_filesystem_size_bytes
You can however generate your alerting rules programatically: make a script
that writes out a rules file, then hits the
reload<https://prometheus.io/docs/prometheus/latest/management_api/#reload>
endpoint.

Hi:
Our prometheus database contains around 5k+ unique type of metrics. With time,
we have defined alerting rules to detect deviations.
However, given the number of growing metrics, it is becoming difficult to
expand the alerting rules.
Generally we are interested in increase/decrease of values in the metrics when
compared to a previous time-interval. Keeping this in mind, is it possible to
write a query where metric name is not specified, instead it picks up all
metric names available in database in sequence.
e.g. #metrics(5min) /#metrics(30 mins) > 50
all unique metric names are picked from database.
Thanks,
Naveen
