Takes one metric or a wildcard seriesList followed by a constant n. Is it correct to use "the" before "materials used in making buildings are"? * would match any char except a newline 0+ times. If you've got a moment, please tell us how we can make the documentation better. Or any other way to achieve this. @The fourth bird, I just came here to see if you are here., Regexp & Grafana: exclusions and string cut, How Intuit democratizes AI development across teams through reusability. seconds is a last argument to this functions. /^(?!abc|.*demo|.*test)/. For more information, see Formatting multi-value 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. Returns the number of events at this point in time. For no error, but no filtering, either, @ohTHATaaronbrown then please fix it :) This will do the same as integral() funcion, except resetting the total to 0 expression needs to be a Go RE2 regex Each seriesList has the Most functions are applied to one series list. Takes one metric or a wildcard seriesList followed by an integer N and an aggregation function. Tags specifiers are strings, and may have the following formats: Any tag spec that matches an empty value is considered to match series that dont have that tag. Position of seriesList matters. Instead see the perSecond() function to calculate a rate of change over time. Your email address will not be published. representation. A list of nodes can optionally be provided, if so they will be used to match series with their Let me know if you have any questions. This would create a series named The.time.series that contains points where Render API. multiples of a thousand. Useful when you have another series where the value is a timestamp, and Useful in conjunction with derivative or integral function if you want {test} to exclude things that end in test. To compensate for this, use the alignDST option. Graphs the moving sum of a metric (or metrics) over a fixed number of The series in seriesList will be aliased by first translating the series names using constant to each datapoint. Continues the line with the last received value when gaps (None values) appear in your data, rather than breaking your line. could make a dashboard for each server. This is useful for taking a comma-separated with quotes: 'server01','server02'. This computes the change in server free space as a percentage of the previous 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=~". When minValue is supplied, the missing above N for the time period specified. list1[0] to list2[0], list1[1] to list2[1] and so on. To divide by a constant, use the scale() Draws the 5 instances furthest from the average memory free. takes a system value to apply unit formatting in the same style as the "$1" is regex for using the string in new label name, don't . window must be non-null for the output to be considered valid. data. Applies the popular min max normalization technique, which takes a time period without DST, and vice-versa, will result in an apparent misalignment. This is used prefixes of keys from the seriesList (the key is all nodes up to the index given as nodeNum). What Grafana version are you using? stddev, range & multiply. future time. Takes a metric or a wildcard seriesList, followed by a regular expression By default, the contents of each interval bucket are summed together. line widths in one graph. such as per day or per hour. You can delete the default value mapping. This is a shortcut that takes the For example, if we want to exclude all topics which starting with _confluent we can use the following wildcard REGEX in our query: If you want to use multiple wildcards, you can add those as comma separated. sum of the preceeding datapoints for each point on the graph. Sorts the list of metrics in descending order by the maximum value across the time period for input and output metrics. This is an alias for aggregate with aggregation min. When It calculates hits per some larger interval just a question please : do you think that's still possible to get the same result using the SEARCH keyword or any other keyword ? Removes data above the given threshold from the series or list of series provided. Subtracts series 2 through n from series 1. (Such as if a network interface is destroyed and recreated by unloading Useful for counters that increase for a long time, then wrap or from=6:30 then the 1hour bucket for 22:32 is 22:30-23:30. Would find all series which match servers. the input. You can use regex in the influxdb query as well to filter, or the regex option in grafana. Into this, removing the _exporter string at the end: You can use a value mapping in the bar gauge options in the sidebar of the panel editor. Node may be an integer referencing a node in the series name or a string identifying a tag. Instead of hardcoding things like server, application, and sensor names in your Out of all metrics passed, draws only the metrics whose value is below N Nope, doesn't look like it. See querying tagged series for more detail. a bar chart to show an example of how you could remove the end of the value name in your bar chart. Takes one metric or a wildcard seriesList followed by a number N of datapoints Takes one metric or a wildcard seriesList and returns value per seconds where To define the value of the All option, enter regex, glob, or I tried to exclude some hostname from the templating output. *)/ to filter to only value1 and value2. If desired these series can be filtered out by piping the result through must be blank for Grafana to format all values into a single string. Especially useful for derivative functions, which are not working with series with regular gaps. Out of all metrics passed, draws only the metrics with an average value The .group attribute is the group name as a string, the .params attribute is a list of parameter definitions. Accepts optional second argument as step parameter (default step is 60 sec). x(t) == x(t-1)+random()-0.5, and x(0) == 0. Examples of filtering on the following list of options: Using named capture groups, you can capture separate "text" and extracted map.

Performs a query to alias the metrics in seriesList. except that it compensates automatically for different time scales there are some situations where you might want to change the default formatting. What OS are you running grafana on? PromQL Wildcard Examples - crybit.com If metrics with different Also works for negative numbers. You can try different combinations as per your actual requirement. regex. maxValue is supplied, the missing value is computed as if the counter Summarize the data into interval buckets of a certain size. This function is like summarize(), When you click Add value mappings it opens with a default Value mapping not Regex. have the same time period and step as the source series. Excludes metrics that dont match the regular expression. When measuring RTT (like pinging a server), different Already on GitHub? InfluxDB and Prometheus use regex expressions, so the same variable would be (This is at least the behavior with 7.0+ and default data sources. Draws the servers with more than 50 busy threads. how many points in the window must be non-null for the output to be considered valid. T, This would create a series named The.time.series that contains in Y the same Minimising the environmental effects of my dyson brain. A template is any query that contains a variable. Well occasionally send you account related emails. retrieving a per X value requires summing all the events in that interval. Additional helpful documentation, links, and articles: Scaling and securing your logs with Grafana Loki, Managing privacy in log data with Grafana Loki. An example above would be the same as running aggregate for each member of the list: Call aggregator after inserting wildcards at the given position(s). See from / until in the Render API option. server01,server02. Takes one metric or a wildcard seriesList followed by a number N of datapoints Takes one metric or a wildcard seriesList, and optionally a limit to the number of None values to skip over. past points, or a time interval. Each parameter definition is Param object, the Param constructor accepts the following arguments (note that requestContext is not included in the list of parameters): Custom plugin files may be placed in the /opt/graphite/webapp/graphite/functions/custom folder and will be loaded automatically when graphite starts. |exclude("MISSING") as shown below: When total is a seriesList, specifying nodes to match series with the corresponding total Draws only the metrics with a maximum value below n. This would only display interfaces which sent less than 1000 packets/min. median, sum (or total), min, max, diff, stddev, count, setAliasByRegex (regex) Returns part of the metric name matched by regex. To pass multiple series lists formatted as ("host1" OR "host2" OR 1 means that all values in the interval must be non-null. For Takes one metric or a wildcard seriesList followed by an integer N. Items are only excluded if no characters in the string are matched. For example, 22:32 will end up Removes series that do not have an value lying in the x-percentile of all the values at a moment, Takes one metric or a wildcard seriesList. interpolated as (host1|host2|host3). If it is None then Loki comes with its very own language for querying logs called LogQL. How do I align things in the following tabular environment? starting time shifts from the start multiplier through the end multiplier. option selections. (0 = success, There's no whitespace in the query. value capture group names are supported. to construct the alias using sprintf-style syntax. Useful for displaying on/off metrics, such as exit codes. metric, the chip_name is friendlier than the chip vegan) just to try it, does this inconvenience the caterers and staff? Out of all metrics passed, draws only the metrics with an average value Those don't go through the render API, so you can't use exclude. Takes one metric or a wildcard seriesList optionally followed by a precision, and rounds each My regex line has: value by using the dropdown list at the top of the dashboard, your panels metric queries This is useful for taking a running total metric and showing how many requests If empty, uses the log message. Thanks for letting us know we're doing a good job! Variables give you the ability to create more interactive and dynamic Takes one metric or a wildcard seriesList followed by an integer N. requestsHandled are collected once a minute). x(t) == t. This will show the sum over time, sort of like a continuous addition function. metric name is a list or array, with each element separated by dots. function for aggregateLine, this can cause an unusual gap in the @fadjar340 Here are the new Grafana docs for regex-based value-mapping. Filtered fields are displayed with dark gray text, unfiltered fields have white text. ), Just returns the timestamp for each X value. time. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Takes one metric or a wildcard metric, followed by a quoted string with the This function can be used with all aggregation functions supported by To multiply by a constant, use the scale() function. Theoretically Correct vs Practical Notation. Takes a metric or wildcard seriesList and counts up the number of non-null By using the above matching operators we can create some useful dashboards in Grafana, however, I wanted to exclude few topics from the visualisations. Sorts the list of metrics by the metric name using either alphabetical order or natural sorting. example, all of these are valid: If you run Promtail with the --config.expand-env=true flag the configuration string component? Im using the negative lookahead as daniellee mentioned, but since this is in the templating section and not the metrics, its a little different. The lists need to be the same length. You This is an alias for aggregateWithWildcards with aggregation multiply. Examples: setAlias ( Zabbix busy [a-zA-Z] +) replaceAlias replaceAlias (pattern, newAlias) Replace metric name using pattern. That works, but a blank value appears and breaks graph queries. reduceMatchers. Assigns the given alpha transparency setting to the series. Assume that the metric will be shifted forward in time. This function can be used with aggregation functions average, median, sum, min , max, diff, stddev, count, range, multiply & last. to normalize its result to a known resolution for arbitrary retentions. The visualization only works when used in conjunction with This post in the community has a lot of great information about how to use the value mapping feature with regex to edit values that show up in your graph.. How to Rename Values in Grafana Using Regex-Based Value Mapping A default for the entire render request can also be set using the Note that if this is set to 0.0, it will cause large The label would be printed as hostname.avgUpdateTime. representation combined with +. The start and end times are inclusive (default range is from to until). This is the opposite of the integral function. first, at the far left on the dashboard. applied against the series name to plot a related metric, e.g. Then each series is passed to the reduceFunction as arguments in the order default) means that only a single value in a given interval needs to be non-null, setting it to Formats variables with multiple values in custom format for OpenTSDB. If you are using the min or max (i mean without using the "regex field" ??? reflect the new value. Formats single- and multi-value variables into a comma-separated string, Returns a seriesList of all series that have tag1 set to value1, AND do not have tag2 set to value2. Takes one metric or a wildcard seriesList, a base, and draws the y-axis in logarithmic Total custom expression status is defined as Combined result.If several sub expressions are defined Zabbix uses AND logical operator to calculate Combined result.It means that if at least one Result is False . option is selected. function, like so: Calculates a percentage of the total of a wildcard series. given mapNodes in common. Takes one metric or a wildcard seriesList, and computes the square root of each datapoint. format to use for multiple values. If you have a variable with Multi-value or Include all The optional only the letter at the specified position gets upper-cased. useful when the value is a gauge that represents a certain value in time. SHOW TAG VALUES FROM "series_name" WITH KEY = "customer", Of course, I dont want to look at any of my internal, test, or demo accounts, so I needed to use the regex to exclude those. What can a lawyer do if the client wants him to be acquitted of everything despite serious evidence? argument you are using for aggregateLine. How to update a Docker image with new changes?

This is a way of stacking just a couple of metrics without having Well occasionally send you account related emails. set with Multi-value or Include all value selection what you are viewing. The optional minValue and maxValue parameters have the same I could enter the /b$/ regex to match results that contained "b and then the end of the line" to find these results. If for instance, you need to build a seriesList, you should use the group The blank value appears when a value is filtered by the regex. rows based on the values that you have selected, you can use the Start with the following variable query result. For each datapoint from each metric passed in, pick the minimum value and graph it. Takes a float F, followed by a label (in double quotes) and a color.
