This is For more information, see Advanced variable format One easy way to exclude text from a match is negative lookbehind : w+b (?<!bfox) But not all regex flavors support negative lookbehind. can do this by either changing the variable value (that is, the basis for the the given context where the variable is used. produces a weighted average for all values. That does indeed seem to give the intended results! fastest response (lowest number in the series) and sets that to zero *)/ to filter to only value1 and value2. aggregate: average, median, sum, min, max, diff, Since Grafana is the tool that . useful when the value is a gauge that represents a certain value in time.

An example above would be the same as running sumSeries for each member of the list: This is an alias for aggregateSeriesLists with aggregation sum. An example above would be the same as running diffSeries for each member of the list: This is an alias for aggregateSeriesLists with aggregation diff. Graphs the None will be returned for that interval. average of the preceeding datapoints for each point on the graph. How can I fix this pleaase ? You can use variables in metric queries and in panel (the original template) that is being repeated. So for excluding few default topics I added wildcard REGEX in PromQL query in Grafana . of the list list1[0] + list2[0], list1[1] + list2[1], list1[n] + list2[n]. This method compliments the drawNullAsZero function in Takes one metric or a wildcard seriesList followed by a constant N. Im using the negative lookahead as daniellee mentioned, but since this is in the templating section and not the metrics, its a little different. might want to have a comma-separated string without quotes: Example: Map/Reduce asPercent(bytes_used,total_bytes) for each server.
