I have some data I am querying from Prometheus, a range vector, that I am currently getting via sum by (label1, label2) (series_name), and as expected, it gives me the most recent results of the sums by the labels. I am trying to change it to get the results over a timeframe (let’s say 1 minute with a resolution of 5 seconds).

I was going through promQL querying basics and noticed a statement which does not make sense.

I have a promQL expression like this- sum(metric_1) by (label_1). Now, I want to filter out the output of the expression using another label label_2. Something like this- (sum(metric_1) by (label_1)){label_2="some_value"}. But, this is not working and is giving a parse error. How can I achieve this?

I have a set of applications which are being monitored by Prometheus. Below are sample time series of the metrics:

I am trying to write an alert based on runaway thread growth and while playing around with PromQL. And the numbers don’t add up at all.

Lets assume Prometheus instance is scrapping data each 15 sec

I’m encountering a small issue with Prometheus. I’m relatively new to it, so I’m not yet very experienced.

How can I create a query in PromQL so that it displays all the metrics that contain the xxx label? I can’t find which metric the label belongs to.
