Hi Folks, This is my first question here and it is not specifically about prometheus but about the way metrics are logged to a file. I hope you can help.
We've implemented a service which logs metrics in the open metrics format and as recommended in this page <https://prometheus.io/docs/instrumenting/exposition_formats/#text-based-format>. So typical metric entries will look like this: app_disk_used_bytes 5.20941207552e+13 1588085025536 app_disk_free_bytes 7.1712562479104e+13 1588085025536 app_io_counters_read_bytes 2.4027136e+07 1588085025536 My doubt is - if/when errors occur when gathering a metric, how do we log them in this file? Can the "value" be replaced with a text indicating an "error". Or is the recommendation that errors not be logged and be recorded elsewhere? I asked this question on the git repo <https://github.com/prometheus/docs/issues/1644> and was advised to try asking here instead. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
