Hi Brian, thank you for you replay. The first thing with "*GaugeMetricFamily" * I figured out just a few minutes after my first reply.
To the second thing you pointed out: Can you give me an example for how to create a registry per request? If i try to use "*req = REGISTRY()*" i get the error "'*CollectorRegistry' object is not callable*". Brian Brazil schrieb am Dienstag, 22.
