Dear Grafana Community!
I am quite new in the world of Grafana and I am looking for showing metrics from log content parsed with Promtail to labels.
Did I get it right from the newsletter of the Loki 0.4.0 that via new Prometheus compatible API it is possible to do it?
If it is not necessary I would like to keep the tools I am using as minimum it is possible: Promtail, Loki, Grafana.
My use case would be to get out/parse metrics from log lines and show on Grafana. E.g. in every 10 seconds a new log line is appearing in log file showing some characteristics of the system like free memory, network usage, etc.
I am already able to parse the log lines with Promtail as labels and send to Loki.
Is is possible to reference only the labels by its name to show the values over time?
