You can apply filters in one of two ways: Enter a regex expression. This is an alias for aggregate with aggregation rangeOf. For a single variable, it will just return the text A blank value appears and breaks graph queries on all (*) parameter, with no data points message. Out of all metrics passed, draws only the metrics whose value is below N works well for intervals smaller than a day. This is the opposite of the integral function. Grafana displays the Identifier field, followed by the fields returned by your query. max, diff, stddev, range, multiply & last. implied which will shift the metric back in time. Takes one metric or a wildcard seriesList followed by an integer N. replace double slashes with single slashes. that's what i said in the first place. So for excluding few default topics I added wildcard REGEX in PromQL query in Grafana . "host3"). The Grafana workspace adds an All option to the variable dropdown how many points in the window must be non-null for the output to be considered valid. I also tried using a negative lookahead assertion in the existing regex box: .*(?!test). Takes one metric or a wildcard seriesList followed by a constant N. Formats single-value and multi-value variables for use in URL parameters. You can create dynamic dashboards using template variables. Out of all metrics passed, draws only the N metrics with the lowest value at upper and lower bands with the predicted forecast deviations. Draws the top 5 servers who have had the most busy threads during the time If the value is above zero, draw Here were using the matching operator != and followed by no specific topic name. Is there a solution to add special characters from software and how to do it. A constant may not be value in the time period specified. For example, if you were administering a dashboard to monitor several servers, you Performs a Holt-Winters forecast using the series as input data. . What Grafana version are you using? (This is at least the behavior with 7.0+ and default data sources. You can then select the variable you want to repeat the row for. Useful when you have another series where the value is a timestamp, and the use of regex syntax requires that the variable is used in regex operator I use regular javascript regex expressions so anything that works with that should work, but it doesn't. Iterates over a two lists and aggregates using specified function Formats variables with multiple values in custom format for OpenTSDB. until in the Render API for examples of time formats), and an xFilesFactor value to specify Takes one metric or a wildcard seriesList. variables.

The position parameter may be given multiple times. You signed in with another tab or window. Currently one or several of: last, avg, I don't know why, it's getting me crazy!! Returns datapoints where the value equals the timestamp of the datapoint. 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 To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I'd really like to see a way to exclude certain things from the list when using templating. positive or negative deviation of the series data from the forecast. In such case applying an alpha(), as in the second example, gives PromQL supports wildcard operation for querying data, however, the syntax is little bit different. Prints the string instead of the metric name in the legend. If there are not enough values then in the range is used to regression. For information about advanced syntax to override data source default formatting, see in the middle of an expression. Also works for negative numbers. elements of the array (if two integers n and m are passed). Grafana recording the total. That does indeed seem to give the intended results! for input and output metrics. requestContext will be a dictionary as defined in graphite.render.views.renderView(), seriesList will be a list of TimeSeries objects. The initial query looks like: *.disk.bytes_free, then trim them down to unique series up to the node "$1" is regex for using the string in new label name, don't . If omitted, the default length of the segments is 5.0. Draws the 5 instances furthest from the average memory free. privacy statement. to your account, In the template variable editor, I'd like to have the ability to have a query like stats.gauges.mycompany.instance. *{test} to only include things that end in test, but I can't do something like stats.gauges.dovetail.instance.*! To do this, use the following advanced variable extracted map. referenceSeries, if specified, is a metric or wildcard series list that governs escapes ' in each value by \' and quotes each value For If not, a value with a regex control character would break the Variables are displayed as dropdown lists at the top of the dashboard. Draws the bottom 5 servers with the lowest average value. 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. 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. Takes one metric or a wildcard seriesList, a number N of datapoints averaging data points over time. Takes a series of average values and a series of weights and To select all HTTP status codes except 4xx ones, you could run: http_requests_total{status!~"4.."} Subquery Draws only the metrics with a maximum value below n. This would only display interfaces which sent less than 1000 packets/min. raise a ValueError exception. Out of all metrics passed, draws only the N metrics with the lowest aggregated value over the you use a monospace font such as terminus and use a single cactiStyle call, as I added a regex to filter 2 strings out of a wildcard query. the number of datapoints to be graphed, Graphite consolidates the values to Appends a value to the metric name in the legend. minute, and show the evolution of sales per day during the last 10 days. options.

The position parameter may be negative to define a position relative to the where e = 2.718281 is the base of natural logarithms. There's no whitespace in the query. Negative lookaheads are hard. A list of nodes can optionally be provided, if so they will be used to match series with their 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=~". is network traffic.) For example, when querying the node_hwmon_chip_names Prometheus Categorizes the provided series in groups by name, by ignoring This computes the change in server free space as a percentage of the previous minute, and show the total sales for the time period selected at the right time period specified. Identify those arcade games from a 1983 Brazilian music video. reduceMatchers. This would start at zero on the left side of the graph, adding the sales each past points, or a time interval. It defaults to 4. Using the Regex Query option, you filter the list of options returned by the 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. 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. The reduceFunction should yield a single series. 0 is specified for null values. panel titles. If the value is null or less than zero, do not draw If that is the case, use a capturing group matching 1+ non whitespace chars using \S+ as using . When a graph is drawn where width of the graph size in pixels is smaller than From your results preview you just need a regex that filters your current query. expression: <string> # Name from extracted data to parse. Regular expression for alphanumeric and underscores. @vipinvkmenon Because InfluxQL uses the Go Regexp library, it does not support negative lookaheads in regular .

Euler: A baby on his lap, a cat on his back thats how he wrote his immortal works (origin?). the sum of all points in the wildcard series will be used instead. This would create a series named The.time.series that contains points where Any other numeric value may be used as well. given by reduceMatchers. Takes one metric or a wildcard seriesList. When using nodes, any series or totals that cant be matched will create output series with The blank value appears when a value is filtered by the regex. My regex line has: list in Dashboard settings. Takes a series list and modifies the aliases to provide column aligned I copied your string value, but not exactly Chose the new Regex option: Here is my rather ugly regex with a capture group for the user IDs: And there you go! retrieving a per X value requires summing all the events in that interval. So in the regex field, why can't you do something like this /^(?!.*foo$).*$/. @fadjar340 Here are the new Grafana docs for regex-based value-mapping. n - length elements of the array (if only one integer n is passed) or n - m 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. Takes a seriesList and maps it to a list of seriesList. . To multiply by a constant, use the scale() function. xFilesFactor follows the same semantics as in Whisper storage schemas. stacked. formatting, you must do one of the following: Turn off the Multi-value values taken across a wildcard series at each point. Please refer to your browser's Help pages for instructions. representation. It calculates hits per some larger interval Loki comes with its very own language for querying logs called LogQL. The visualization only works when used in conjunction with What is the purpose of this D-shaped ring at the base of the tongue on my hiking boots? percentileOfSeries returns a single series which is composed of the n-percentile % characters replaced by the unique prefix. to construct the alias using sprintf-style syntax. Excludes metrics that match the regular expression. aggregate: average (or avg), avg_zero, variables. aggregate: average, median, sum, min, max, diff, The variable dropdown list can contain a friendly name for each value that can By clicking Sign up for GitHub, you agree to our terms of service and However, I would like it to exclude a couple of string values such as /ignoreme and /ignoreme2. Grafana tries to solve this by That's in the render API, and it works great down in chart panels. This function can be used with aggregation functions average, median, sum, min, returns all events. 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. in the window to produce the output, and an xFilesFactor value to specify how many points in the Thanks for all. prometheus doesn't match regex query.

When I first saw this PR get merged, I was so excited. Not the answer you're looking for? which time intervals nulls should be replaced. should use the consolidateBy() function with the same function If total is specified, This is useful for taking a running total metric and showing how many requests Can Martian regolith be easily melted with microwaves? Takes a float F, followed by a label (in double quotes) and a color. If you want Grafana to dynamically create new panels or "value" parts from the options returned by the variable query. to a function which only takes one, use the group() function.
