Hi, I using Prometheus to collect Spring Boot service metrics in Java.
But I found a problem that data still exsit after pull, that made the
instant data is not correct.
Like at now there has one label like 'app_version{version=a} 100',
then the metrics updated, and add a new label value b, the metrics
come to 'app_version{version=a} 50' and 'app_version{version=b} 50';
Then, label a no longer update, and metrics come to
'app_version{version=b} 100'.
When I pull metrics form Spring Boot service, the metrics is
'app_version{version=a} 50' and 'app_version{version=b} 100'. But
expect data should be 'app_version{version=b} 100' only.
How could I fix this issue? Thanks.
I think possibly you aren't using labels in the way expected.
Labels are used to "slice & dice" the data, so for example to be able to
see which specific HTTP response code was returned from a web call, etc.
What is the value of the metric app_version supposed to signify?
