Hi,
i have this output from prometheus-postfix-exporter via web.page.get:
For getting values i need to remove headers on beginning and the trash on the end after metrics. But my regular preprocessing doesn't work:
Option A:
1. regex to remove headers - works
2. regex to remove ending trash after metrics - works on preprocessing test, fail on collected item
Option B:
1. regex to get all # and metrics only - fails on preprocessing tests
Any idea? I don't want to use http agent.
Thanks.
