For clusters K8s 1.16 and above. This work is in progress and we are working to align everyone so that we can improve memory usage for Prometheus queries.

Well demo all the highlights of the major release: new and updated visualizations and themes, data source improvements, and Enterprise features. var adjustment = (left + cardWidth) - (windowWidth + 25) + 50; Run some query like {namespace="caascad-monitoring"} for a period of 15 minutes. Hi! Memory seen by Docker is not the memory really used by Prometheus. Is it correct to use "the" before "materials used in making buildings are"? The parameter FOR specifies the amount of time for which an alert rule must be true before the ALERTING state is triggered and an alert is sent via a notification channel. It saves these metrics as time-series data, which is used to create visualizations and alerts for IT teams. the same as [2], but we would try to do the JSON->dataframes transformation in a streaming fashion, to limit memory use.

How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? WMI Exporter is an exporter utilized for windows servers to collects metrics like CPU usage, memory, and Disk usage. How to reproduce it (as minimally and precisely as possible): The issue has been caused by the fact that Prometheus datasource has been refactored from a frontend datasource to a backend datasource and since 8.3 all queries have to be processed in Grafana server: The text was updated successfully, but these errors were encountered: @gabor as discussed, here's the issue.

For example, if the prometheus response return 300 separate time-series blocks, the response can be quite big, even if the number of data points for 1 time-series is smaller. type: 'post', I followed the steps listed above and the top image with v9.0.0 hits about 50,000,000 while v9.3.1 in the bottom hits 17,500,000.

Depending on the size of the result set, the memory usage has increased by 1.5x to 3x times, when comparing 8.3.3 to 8.2.7. Like Armand said it would be interesting to know the number of dimensions and the volume of data that is being returned. We can draw a graph also using those metrics on Prometheus. If this issue still persists in the latest version of 9.x please feel free to re-open it with some profiling data if possible. What I have now are time series limit CPU/memory. Making statements based on opinion; back them up with references or personal experience. to be exact, how much memory we use to handle the prometheus query, parse the returned JSON and create the grafana dataframes (that will be returned to the browser).

What is the point of Thrower's Bandolier? Thanks for contributing an answer to Server Fault! Not sure if this is an alternative/useful, but in case you're not aware you can configure a global response limit to limit the size of responses from outgoing HTTP requests.
