Return all time series with the metric http_requests_total: Return all time series with the metric http_requests_total and the given VictoriaMetrics handles rate () function in the common sense way I described earlier! Since we know that the more labels we have the more time series we end up with, you can see when this can become a problem. Please see data model and exposition format pages for more details. The more labels you have, or the longer the names and values are, the more memory it will use. Run the following commands on the master node, only copy the kubeconfig and set up Flannel CNI. One or more for historical ranges - these chunks are only for reading, Prometheus wont try to append anything here. Is there a solutiuon to add special characters from software and how to do it. Those memSeries objects are storing all the time series information. The next layer of protection is checks that run in CI (Continuous Integration) when someone makes a pull request to add new or modify existing scrape configuration for their application. SSH into both servers and run the following commands to install Docker. This helps Prometheus query data faster since all it needs to do is first locate the memSeries instance with labels matching our query and then find the chunks responsible for time range of the query. It saves these metrics as time-series data, which is used to create visualizations and alerts for IT teams. Ive added a data source(prometheus) in Grafana. When you add dimensionality (via labels to a metric), you either have to pre-initialize all the possible label combinations, which is not always possible, or live with missing metrics (then your PromQL computations become more cumbersome). For that reason we do tolerate some percentage of short lived time series even if they are not a perfect fit for Prometheus and cost us more memory. The main motivation seems to be that dealing with partially scraped metrics is difficult and youre better off treating failed scrapes as incidents.
