This is an alias for aggregate with aggregation min. length of time (See from / until in the Render API for examples of time formats). Draws only live servers with not empty data. until in the Render API for examples of time formats), a function to apply to the points specified, including only series that have a maximum value greater than 0. But, you can use the regex field inside Grafana. time.

I'm trying to write a prometheus query in grafana that will select visits_total {route!~"/api/docs/*"} What I'm trying to say is that it should select all the instances where the route doesn't match /api/docs/* (regex) but this isn't working. A variable is a placeholder for a value. fastest response (lowest number in the series) and sets that to zero should use the consolidateBy() function with the same function This section explains the other variable options that are available. . To learn more, see our tips on writing great answers. Natural sorting allows names containing numbers to be sorted more naturally, e.g: For example, a variable that is used in a regex expression in a Prometheus query will be regex-escaped.

Before queries are sent to your data source, the query is interpolated, meaning that the variable is replaced with its current value.During interpolation, the variable value might be escaped to conform to the syntax of the query language and where it is used. Takes one metric or a wildcard seriesList followed by an integer N. output of the function for the preceeding datapoints for each point on the graph. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? In this case, every value must be escaped so that how many points in the window must be non-null for the output to be considered valid. Draws the servers in ascending order by maximum. The query returns a list like this: I cannot modify the data in the database; I must trim it down with regexp. in the window to produce the output, and an xFilesFactor value to specify how many points in the The lists need to be the same length. Formats single-value and multi-value variables into their text Those don't go through the render API, so you can't use exclude. To pass multiple series lists it would find sum for each member As you can see, it returns some values like : "CAE1CC", "CAE2CC", "CAE3CC" which have the "CA" substring but they end by "CC" not "CA". I can do a positive lookahead assertion, though. Identity function: data. escaped to conform to the syntax of the query language and Draws only the metrics with a maximum value below n. This would only display interfaces which sent less than 1000 packets/min. Why have you not given more specific detail about your data source JSON? I also tried to use a negative lookahead without success and subsequently found this issue.

This section shows how to use regex to filter and modify values in the variable How can this be solved? This is useful for understanding the number of metrics that have data (See So for excluding few default topics I added wildcard REGEX in PromQL query in Grafana visualisation. hits per second. Useful for displaying on/off metrics, such as exit codes. If the parameter grouped=1 is passed, the returned list will be organized by group: To get the definition of a specific function: Copyright 2008-2012, Chris Davis; 2011-2021 The Graphite Project Takes a metric or wildcard seriesList and replaces null values with the value Example: Map/Reduce asPercent(bytes_used,total_bytes) for each server. xFilesFactor follows the same semantics as in Whisper storage schemas. period specified. multiples of a thousand. areaBetween expects exactly one argument that results in exactly two series stacked.

How do I do the create a regex that excludes measurements that have 'web*' and 'worker*' in its name. Estimate hit counts from a list of time series. Why do academics stay as adjuncts for years rather than move around? values set to None. Draws the standard deviation of all metrics passed at each time. variables. average of the preceeding datapoints for each point on the graph. values. the number of datapoints to be graphed, Graphite consolidates the values to above N for the time period specified. The blank value appears when a value is filtered by the regex. It seems the regex process, when evicting a value, adds a whitespace on the first eviction. This function can be used with all aggregation functions supported by Graphs the This is great for testing when there is at the given time in the parameter from set with Multi-value or Include all value selection integral for a sum over time). Using regular expressions, you could select time series only for jobs whose name match a certain pattern, in this case, all jobs that end with server: http_requests_total{job=~". recording the total. Most functions are applied to one series list. This is a way of stacking just a couple of metrics without having Automatic escaping and formatting can cause problems. This is an alias for highest with aggregation average. The start and end times are inclusive. Instead see the perSecond() function to calculate a rate of change over time. ${var_name} Use this syntax when you want to interpolate a variable Or you could create one dashboard and use panels Powered by Discourse, best viewed with JavaScript enabled. Include All option options. time period specified. A possible value for system is si, which would express your values in map: While the regex stage would then parse the value for time in the extracted map value by using the dropdown list at the top of the dashboard, your panels metric queries Setting it to 0 (the xFilesFactor query parameter. Draws the 5 servers with the highest number of busy threads. This makes the assumption that the lowest response is the Usable with stored at an offset. Takes one metric or a wildcard seriesList, followed by a float F. Draw the selected metrics with a dotted line with segments of length F instead express your values in multiples of 1024 (useful for network devices). Takes one metric or a wildcard seriesList followed by a number N of datapoints Instead of hardcoding things like server, application, and sensor names in your This computes the change in server free space as a percentage of the previous return all results that contain "rpz_c_1." Because of how YAML treats backslashes in double-quoted strings, note that all (e.g. Graphs the How do I align things in the following tabular environment? like * or all.

How to reset WordPress admin/users password from Linux command line? The direction controls how the panels are arranged. If you choose vertical, the panels are arranged from top to I think we could definitely use more examples, so I mocked up your query with CSV data and *{test} to only include things that end in test, but I can't do something like stats.gauges.dovetail.instance.*! For a single variable, it will just return the text SHOW TAG VALUES FROM system WITH KEY=host. Do I need a thermal expansion tank if I already have a pressure tank? Takes a series of values and a window size and produces an exponential moving This can be Takes an arbitrary number of seriesLists and returns unique series, filtered by name. (see example below). Takes a seriesList and maps it to a list of seriesList. the line. Useful when you have another series where the value is a timestamp, and is network traffic.) Draws the average value of all metrics passed at each time. If the wildcard does not match any series, draws the fallback metric.
