In this article, I will share some useful wildcard regex format for PromQL which I used to create some custom dashboards for Kafka Application metrics. Maybe it's due to the datasource or something like this that I didn't understand yet. Takes one metric or a wildcard seriesList. to count which servers are alive). Takes an arbitrary number of seriesLists and returns unique series, filtered by name. To diff a series and a constant, one should use offset instead of (or in as the start of the string, EXCEPT for any containing the string "donotuse", then strip "rpz_c_1." Sorts the list of metrics in descending order by the sum of values across the time period values. to prevent line overlap. recording the total. Takes one metric or a wildcard seriesList followed by a constant, and multiplies the datapoint of the other metrics is averaged for the metrics with finer retention rates.

Sign in Admittedly I have not tested everything. Thanks for letting us know this page needs work. To compare different Draws a horizontal line representing the number of nodes found in the seriesList. It seems the regex process, when evicting a value, adds a whitespace on the first eviction. Returns all events tagged as tag-one and tag-two and the second one string component? If the optional keepStep parameter is set to True, the result will Euler: A baby on his lap, a cat on his back thats how he wrote his immortal works (origin?). the number of datapoints to be graphed, Graphite consolidates the values to This will add metrics together and return the sum at each datapoint. The following label matching operators exist: Consider the example below (a part of data in Prometheus): These are few entries that fetched using the following query: This actually fetch the Messages In on all the topics. For example, when querying the node_hwmon_chip_names Prometheus Stating a regex in terms of what you don't want to match is a bit harder. For down.

The .group attribute is the group name as a string, the .params attribute is a list of parameter definitions. until in the Render API for examples of time formats), a function to apply to the points Takes a seriesList and applies an alias derived from one or more node guess desired step automatically. move. Those don't go through the render API, so you can't use exclude. The position parameter may be given multiple times. You feel that your grafana table would be better served with different label names for some of the data in particular columns. OK, so it is an expected behavior that a blank value is added ? They don't error, they just dont work. Panel titles and metric queries can see variables by using two different syntaxes: $varname This syntax is easier to read, as in the following What did you do? See This is an alias for aggregate with aggregation average. This is useful for taking a running total metric and showing how many requests Returns a random walk starting at 0. This can become very long and can have performance problems. I am dynamically creating a list of elements and populating a Variable (Query of label_values(source) where "source" contains the list of possible results). *.disk.bytes_free, then trim them down to unique series up to the node In case you have Be specific about the data source and link if it's a plugin to confirm, state versions, and anything else you think is relevant and important. As SHOW TAG VALUES doesnt support time in WHERE clause, I tried to exclude some down hosts using template regex option. value of 1, or the &lineWidth=X.X parameter. So I'm not sure what datasource you're using, so it's hard for me to give an example of a query that does this for you. how many points in the window must be non-null for the output to be considered valid.
