This is better illustrated by looking at a metric like EnqueueCount:Notice that we have multiple points being gathered across differing “destinationName” objects.Here are some examples of a Grafana Prometheus dashboard.Once we have the right metric coordinates captured, it’s time to create our first Dashboard in Grafana. For now, copy the SystemCPULoad query that we pulled from Prometheus earlier into the query line:Upon clicking off of the query, you’ll see that Grafana immediately executes the query and starts rendering graph data:Move to the General tab, and let’s give our Graph a suitable name:Now let’s label our Y axis and change our number format to Percent(0.0-1.0). Grafana is a graphic interface with a dashboard which supports Promethus as a back-end to query for the data to generate the graph. Con esto echo ya tenemos instalado Grafana en nuestro sistema.
