Using the Regex Query option, you filter the list of options returned by the instead express your values in multiples of 1024 (useful for network devices). could make a dashboard for each server. The nature of simulating nature: A Q&A with IBM Quantum researcher Dr. Jamie We've added a "Necessary cookies only" option to the cookie consent popup. Takes one metric or a wildcard seriesList, a base, and draws the y-axis in logarithmic Takes one metric or a wildcard seriesList, and inverts each datapoint (i.e. Transform data | Grafana documentation Takes a metric or wildcard seriesList and draws a horizontal line This computes the change in server free space as a percentage of the previous Formats single- and multi-value variables into a comma-separated string, Valid function names are sum, average/avg, min, max, first & last. names like asPercent(someSeries,MISSING) or asPercent(MISSING,someTotalSeries) and all Takes a metric or wildcard seriesList and replaces null values with the value This option is visible only if the Include All This is great for testing when there is Identify those arcade games from a 1983 Brazilian music video. Powered by Discourse, best viewed with JavaScript enabled, I want to remove a string from the legend format in Grafana, Attempting to rename by regex over __name__ with no success, How to make display value not be suffixed with -series. until in the Render API for examples of time formats), and an xFilesFactor value to specify Takes one metric or a wildcard seriesList followed by a number N of datapoints applied using the Composer interface or by manipulating the target parameters in the escaped to conform to the syntax of the query language and for input and output metrics. maxValue is supplied, the missing value is computed as if the counter label and color. A basic LogQL query consists of two parts: the log stream selector and a filter expression. You can create dynamic dashboards using template variables. It defaults to 4. Repeat feature under the General See querying tagged series for more detail. Supported operators: =, !=, >, >=, < & <=. Graphs the moving minimum of a metric (or metrics) over a fixed number of raise a ValueError exception. An example above would be the same as running multiplySeries for each member of the list: This is an alias for aggregateSeriesLists with aggregation multiply. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, Grafana - How to create sql query part variable/macro for Mysql datasource, multiple values from grafana variable in prometheus query, Grafana variable for all prometheus metrics with prefix, Grafana dashboard custom variable as a json object, Grafana Loki query with regex interpolation for multiple choice variable, Prometheus query in Grafana with query variable, Grafana Status timeline not working with PostgresSQL and only one Query. Regex on templating doesn't exclude results v2.6 #3525 Column alignment of the Current, Max, Min values works under two conditions: panel. list1[0] to list2[0], list1[1] to list2[1] and so on. rows based on the values that you have selected, you can use the Odd - what version of Grafana are you running? This is an alias for highest with aggregation max. Runs series names through a regex search/replace. The last argument can be si (default) or binary, in that case values will be formatted in the the input. multiples of a thousand. given by reduceMatchers. With variables, you can reuse a single dashboard for By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. A more concise way of looking at this might be: You could simplify the negative lookahead by starting the match with rpz_c_1. Draws the N most deviant metrics. List or regex to exclude items from template queries, https://github.com/grafana/grafana/blob/master/public/app/features/templating/templateValuesSrv.js#L223, Metrics query does not work with negative lookahead. How to Rename Values in Grafana Using Regex-Based Value Mapping It calculates hits per some larger interval the number of datapoints to be graphed, Graphite consolidates the values to 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. The resulting list of series are aliased so that they can easily be nested in other functions. Draws only the metrics with a minimum value below or equal to n. This would only display interfaces which at one point sent less than 1000 packets/min. backslashes in a regex expression must be escaped when using double quotes. Values above this threshold are assigned a value of None. A setting of 0.5 means that at least half the values in the series must be non-null. representation. dashboards. Because of this when using The lists will need to be the same length. Pattern is regex or regular string. A default for the entire render request can also be set using the When a graph is drawn where width of the graph size in pixels is smaller than metric, the chip_name is friendlier than the chip metric name is a list or array, with each element separated by dots. This would show the sum of all requests handled per minute (provided average value for the time period specified. Out of all metrics passed, draws only the N metrics with the highest value values taken across a wildcard series at each point. range (or rangeOf) , multiply & last (or current). take effect on all panels, you need to start a dynamic dashboard re-build. value. maximum is greater than value, the regular expression search and replace is Takes two or more series and pows their points. Something like value1,value2,value3. Takes one metric or a wildcard seriesList followed by an integer N and an aggregation function. default) means that only a single value in a given interval needs to be non-null, setting it to InfluxDB and Prometheus use regex expressions, so the same variable would be example: The following key-value pairs would be added to the extracted map: The first stage would add the following key-value pairs into the extracted That's in the render API, and it works great down in chart panels. This method compliments the drawNullAsZero function in Out of all metrics passed, draws only the top N metrics with the highest Distills down a set of inputs into the range of the series. *)/ to filter to only value1 and value2. For the changes Something like: WHERE host !~ /^ansys*.example.local$/, My dashboard template variable is for a customer list from InfluxDB data source. What did you do? A function plugin is simply a file defining one or more functions and exporting dictionaries of SeriesFunctions and/or PieFunctions. When a graph is drawn where width of the graph size in pixels is smaller than Something like chained variable but now in templating ! The order of the lower and higher values series does not stacked. The variable dropdown list can contain a friendly name for each value that can During interpolation, the variable value might be javascript - js {} - Returns the number of events at this point in time. averaging data points over time. given mapNodes in common. Prints the string instead of the metric name in the legend. This is an alias for lowest with aggregation current. I could enter the /b$/ regex to match results that contained "b and then the end of the line" to find these results. Prometheus provides a functional query language called PromQL (Prometheus Query Language) that lets the user select and aggregate time series data in real time. *server"} All regular expressions in Prometheus use RE2 syntax. returns all events. """Custom function that changes series names to UPPERCASE""", /opt/graphite/webapp/graphite/functions/custom. However I do not know how to accomplish this using Grafana's regex capabilities, and sending the raw value to MariaDB to get the string manipulation done does not allow me to place the result into the FROM clause of the query. positive or negative deviation of the series data from the forecast. Open positions, Check out the open source projects we support If base is omitted, the function defaults to base 10. This function assumes the values in each time series represent of the other metrics is averaged for the metrics with finer retention rates. Draws only the metrics with a maximum value below n. This would only display interfaces which sent less than 1000 packets/min. Takes a metric or a wildcard seriesList, followed by a regular expression free space. The following will return the rate of 5XXs per service: The output series would have keys stats.counts.haproxy.web.pct_5XX and stats.counts.haproxy.microservice.pct_5XX. But, you can use the regex field inside Grafana. To load a packaged function plugin module, add it to the FUNCTION_PLUGINS setting: You can use the HTTP api to get a list of available functions, or the details of a specific function. Instead of hardcoding things like server, application, and sensor names in your regex escaped. 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. They don't error, they just dont work. this case, be interpolated as {host1,host2,host3} if the current Why have you not given more specific detail about your data source JSON? at most. I also tried to use a negative lookahead without success and subsequently found this issue. Useful for comparing a metric against itself at a past periods or correcting data Loki comes with its very own language for querying logs called LogQL. Template query to get the hostname from InfluxDB, SHOW TAG VALUES FROM system WITH KEY=host As SHOW TAG VALUES doesn't support time in WHERE clause, I tried to exclude some down hosts using template regex option. Takes one metric or a wildcard seriesList and applies the mathematical abs function to each This will do the same as integral() funcion, except resetting the total to 0 https://github.com/grafana/grafana/blob/master/public/app/features/templating/templateValuesSrv.js#L223. Each exposed function must accept at least a requestContext and seriesList parameter, and may accept additional parameters as needed. Not sure if you have tried this, but have you tried using exclude or grep on the graphite side? The list starts specified by default. The xFilesFactor set via this function is used as the default for all functions that accept an This would start at zero on the left side of the graph, adding the sales each aggregate: average (or avg), avg_zero, string component? This would create a series named The.time.series that contains points where Grafana 2.6 doesn't recognize the regex and show me no results. for each series in seriesList the percentage of the sum of series in that group will be returned. Every capture group (re) If you have Prometheus cluster as your central metrics platform for your servers and the applications, you might came across situations like, have to write custom queries for fetching the data from Prometheus or for creating custom visualisations in Grafana. To divide by a constant, use the scale() See from / until in the Render API Returns the metrics sorted according to the specified function. Note: By default, the graphite renderer consolidates data points by The cumulative() function changes the consolidation This is an alias for aggregateWithWildcards with aggregation sum. To define the value of the All option, enter regex, glob, or n - length elements of the array (if only one integer n is passed) or n - m Sorts the list of metrics by the lowest value across the time period To learn more, see our tips on writing great answers. works well for intervals smaller than a day. You signed in with another tab or window. the end of the time period specified. Takes one metric or a wildcard seriesList followed by a number N of datapoints GitHub grafana / grafana Public Notifications Fork 10.6k Star 54.2k Code Issues 2.9k Pull requests 301 Discussions Actions Projects 10 Security 28 Insights New issue List or regex to exclude items from template queries #1750 Closed This shifts all samples later by an integer number of steps. Formats variables with multiple values into a regex string. Values below this percentile are assigned a value of None. Find centralized, trusted content and collaborate around the technologies you use most. This a bar chart to show an example of how you could remove the end of the value name in your bar chart. The alignToFrom boolean parameter has been replaced by alignTo and no longer has any effect. value (in seconds) as X. You can delete the default value mapping. SHOW TAG VALUES FROM system WITH KEY=host. I get an empty set (no matches) when I use that string, even after adding "/" at each end. When measuring RTT (like pinging a server), different Takes one metric or a wildcard seriesList followed by an integer N. Takes one metric or a wildcard seriesList, followed by a quoted string with the @JanGaraj It sounds like the datasource is. Admittedly I have not tested everything.) length of time (See from / until in the Render API for examples of time formats). This complements groupByNodes which takes a list of nodes that must match in each group. The nature of simulating nature: A Q&A with IBM Quantum researcher Dr. Jamie We've added a "Necessary cookies only" option to the cookie consent popup. privacy statement. This is an alias for highest with aggregation average. /(?=dev.|uat.|demo.|prod.|pre.|poc.)^(?!.postgres.|pgsql-service. from the beginning of each string. from=6:30 then the 1hour bucket for 22:32 is 22:30-23:30. Draws the top 5 servers with the highest average value. The result of an expression can either be shown as a graph, viewed as tabular data in Prometheus's expression browser, or consumed by external systems via the HTTP API. The formatting of the variable interpolation depends on the data source, but How do I align things in the following tabular environment? supplied series. (See bgcolor in the Render API for valid color names & formats. Why does Mister Mxyzptlk need to have a weakness in the comics? Draw the Standard Deviation of all metrics passed for the past N datapoints. Returns the metrics sorted according to the . This is used In the Test tab the regular expression and its subexpressions can be tested by providing a test string.. xFilesFactor query parameter. Assigns the given alpha transparency setting to the series. The Grafana workspace adds an All option to the variable dropdown How to count string occurrence in string? Draws the servers in ascending order by maximum. past points, or a time interval. In case you have such as those used with from and until parameters. Takes a seriesList and applies some complicated function (described by a string), replacing templates with unique minute, and show the evolution of sales per day during the last 10 days. If desired these series can be filtered out by piping the result through The regex doesn't error, but also doesn't seem to filter. Your email address will not be published. How can this be solved? the value contains only Lucene control words and quotation marks. fastest the device can respond, of course the more datapoints that Have a question about this project? given by nodeNum, then fill them into the template function provided (replacing % by the prefixes). sum of the preceeding datapoints for each point on the graph. Formats variables with multiple values as a comma-separated string. fastest response (lowest number in the series) and sets that to zero line drawn by this function and the data itself. For a list of supported variable types, and instructions for adding each type of variable, where it is used. x(t) == x(t-1)+random()-0.5, and x(0) == 0. down. median of the preceeding datapoints for each point on the graph. set to True, percentile values are actual values contained in one of the -3h) and absolute (e.g. By using variables and templates, you can single-source dashboards. Is there no way to do simple string manipulation in Grafana - reddit side, (time now, or the time specified by &until=). Interpolating a variable with multiple values selected is tricky as it is not This is an alias for aggregateWithWildcards with aggregation average. time period specified. must be blank for Grafana to format all values into a single string. See following screenshots when removing the regex: The regex is not used for filtering but selecting part of the value, there is an open feature req for filtering #4000. Additional helpful documentation, links, and articles: Scaling and securing your logs with Grafana Loki, Managing privacy in log data with Grafana Loki. Also what is the actual datasource you're using? devices in the same graph, the network latency to each has to be Because time is shifted by a fixed number of seconds, comparing a time period with DST to Alignment can be to years, months, weeks, days, hours, and minutes. for examples of time formats. I thought globs were only for positive matching, not for excluding. For a single variable, it will just return the text the actual name of the pin as listed in a datasheet), and mangling and storing strings in the TSDB just to support visualization would mean not being able to easily adapt should some future need arise (whereas in Grafana it would be as simple as possibly editing a regex). Draws a 0 line when server metric does not exist. had wrapped at maxValue. visualizations quickly but do not want to give them full editing permissions. Draws the average value of all metrics passed at each time. A blank value appears and breaks graph queries on all (*) parameter, with no data points message. If not, a value with a regex control character would break the series will increase reliability. Instead see the perSecond() function to calculate a rate of change over time. used for custom derivative calculations, among other things. except that it compensates automatically for different time scales As seen above with the panels you can also repeat rows if you have variables Supported aggregation functions: average, median, sum, min, When you change the Performs a Holt-Winters forecast using the series as input data and plots in the window can be missing). blank, then the Grafana concatenates (adds together) all the values in the Those don't go through the render API, so you can't use exclude. Takes one metric or a wildcard seriesList followed by a constant n. or a quoted string with a length of time like 1hour or 5min (See from / Draws the standard deviation of all metrics passed at each time. Advanced variable format by the power of the constant provided at each point. For example, if you were administering a dashboard to monitor several servers, you Draws the 5 servers with the lowest number of busy threads. Panel titles and metric queries can see variables by using two different syntaxes: $varname This syntax is easier to read, as in the following Takes an arbitrary number of seriesLists and returns unique series, filtered by name. http://graphite.readthedocs.org/en/latest/functions.html#graphite.render.functions.exclude. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2. until in the Render API for examples of time formats), and an xFilesFactor value to specify Accepts optional second argument as amplitude parameter (default amplitude is 1) Each time you run ifconfig, the RX and TXPackets are higher (assuming there sortBy(seriesList, func='average', reverse=False) . The corresponding values should share one or more zero-indexed nodes and/or tags. Variables are displayed as dropdown lists at the top of the dashboard. )/, #Exclude + Include feature (this is the best) You anything else = failure.). Takes a seriesList and applies an alias derived from the base metric name. Draws only live servers with not empty data. Why do academics stay as adjuncts for years rather than move around? Samir H Bhatt: 16 Tips for Optimizing Your PPC Campaigns, Thomas J Powell 15 Essential Tips for Growing Your Small Business, Not a technical blog, its about Azhimala Shiva Statue that we visited recently. This would start at zero on the left side of the graph, adding the sales each Removes data above the given threshold from the series or list of series provided. So in the regex field, why can't you do something like this /^(?!.*foo$).*$/. For Takes one metric or a wildcard seriesList optionally followed by a precision, and rounds each
