And to be able to show us the data in nice pretty graphs that we can manipulate, drill-down on, and even set up. however, the relabeling causes the job name to be mysql for all fetches, making this metric unusable for all 3 mysql scrapes. Here is the Corefile for coredns. Each microservice uses the most appropriate technique for horizontal scaling; most are stateless and can handle requests for any users while some (namely the ingesters) are semi-stateful and depend on consistent hashing. Try to increase the default value of the connection timeouts. py3-none-any. Depending on your Ingress config, the export may take too long and timeout. Grafana will give you a plethora of query, calculation, and visualization options that go far beyond this simple UI.
