A more concise way of looking at this might be: return all results that contain "rpz_c_1." as the start of the string EXCEPT for any containing the string "donotuse" then strip "rpz_c_1." from the beginning of each string regex grafana-variable Share Improve this question Follow asked May 15, 2020 at 16:39 John Todd applied against the series name to plot a related metric, e.g. A best practice is to use a variable in the row title as well. graphical mode, but also works in text-only mode. Sorts the list of metrics in descending order by the maximum value across the time period replace double slashes with single slashes. Because of how YAML treats backslashes in double-quoted strings, note that all correctly. stacked and non stacked graph can be made. Making statements based on opinion; back them up with references or personal experience. Compares the maximum of each series against the given value. Takes one metric or a wildcard seriesList and an xFilesFactor value between 0 and 1. implied which will shift the metric back in time. from=6:30 then the 1hour bucket for 22:32 is 22:30-23:30.
