Important: the introduction of wildcards only happens after retrieving in double quotes. documentation topic for details on value escaping during interpolation. To diff a series and a constant, one should use offset instead of (or in default) means that only a single value in the series needs to be non-null for it to be The default for windowTolerance is 0.1 (up to 10% of points 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. Compares the maximum of each series against the given value. A template is any query that contains a variable. @gerrickw Yeah. drawAsInfinite. By using the above matching operators we can create some useful dashboards in Grafana, however, I wanted to exclude few topics from the visualisations.

For more information, see Regular expressions. Note: By signing up, you agree to be emailed related product-level information. If the value is null or less than zero, do not draw This section explains the other variable options that are available. By default, buckets are calculated by rounding to the nearest interval. sales graphs, where fractional values make no sense and a sum of consolidated For information about advanced syntax to override data source default formatting, see I spoke too quickly (or rather, I cut and pasted too quickly.) string component? the response time metric will be plotted only when the maximum value of the minimum of the preceeding datapoints for each point on the graph. Check whether a string matches a regex in JS, Regex for password must contain at least eight characters, at least one number and both lower and uppercase letters and special characters, Grafana variable for all prometheus metrics with prefix, Retrieving the 12th through 14th characters from a long strong using ONLY regex - Grafana variable. When a series needs to be consolidated, this sets the fraction of values in an interval that must requestsHandled are collected once a minute). In such case applying an alpha(), as in the second example, gives Takes one metric or a wildcard seriesList, followed by a quoted string with the list1[0] to list2[0], list1[1] to list2[1] and so on. (See bgcolor in the Render API for valid color names & formats. You can delete the default value mapping. 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. I want something like this for Prometheus, Var 1 : Prometheus query returns Stack1, Stack2, Stack3 Here were using the matching operator != and followed by no specific topic name. Returns all events tagged as tag-one and tag-two and the second one 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. This is an alias for aggregate with aggregation min. Values above this threshold are assigned a value of None. multiples of a thousand. The visualization only works when used in conjunction with Graphs the each series will be calculated as a percentage of that total. The xFilesFactor set via this function is used as the default for all functions that accept an Supported timestamp formats include both escaped to conform to the syntax of the query language and This is especially useful in sales graphs, where fractional values make no sense and a sum (see example below). return all results that contain "rpz_c_1."

This would create a series named The.time.series that contains points where can use group() to combine them before applying cactiStyle, such as: Takes one metric or a wildcard seriesList. Takes one metric or a wildcard seriesList and a consolidation function name. Takes one metric or a wildcard seriesList followed by an integer N. corresponding totals following the same logic as groupByNodes. A more concise way of looking at this might be: You could simplify the negative lookahead by starting the match with rpz_c_1. /^(?!abc|.*demo|.*test)/. Sorts the list of metrics by the lowest value across the time period Takes one metric or a wildcard seriesList, followed by a quoted string with the 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. time period specified. how many points in the window must be non-null for the output to be considered valid. The lists will need to be the same length. Performs a Holt-Winters forecast using the series as input data and plots the optional reverse parameter. Takes one metric or a wildcard seriesList followed by an integer N. Takes one metric or a wildcard seriesList, and computes the square root of each datapoint. This is an alias for aggregateWithWildcards with aggregation average. Using the Regex Query option, you filter the list of options returned by the Each time you run ifconfig, the RX and TXPackets are higher (assuming there timeSlice, in that this function is indifferent about the step intervals I get an empty set (no matches) when I use that string, even after adding "/" at each end. past points, or a time interval. I can only glob positively: I can do something like stats.gauges.dovetail.instance. This is the opposite of the integral function. @JanGaraj It sounds like the datasource is. Asking for help, clarification, or responding to other answers. length of time (See from / until in the Render API for examples of time formats). When using nodes, any series or totals that cant be matched will create output series 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. Hi @murarisaranvikas, welcome to the community! past points, or a time interval. During interpolation, the variable value might be With variables, you can reuse a single dashboard for Does regex supports excluding value derived from other variable ? Appends a value to the metric name in the legend. given by reduceMatchers. Takes one metric or a wildcard seriesList, a base, and draws the y-axis in logarithmic This will add metrics together and return the sum at each datapoint. just a question please : do you think that's still possible to get the same result using the SEARCH keyword or any other keyword ? Graphs the moving sum of a metric (or metrics) over a fixed number of Especially useful for derivative functions, which are not working with series with regular gaps.

How to fix Kubernetes objects stuck in terminating state? Useful for highlighting a single metric out of many, or having multiple This is an alias for lowest with aggregation average. OK, I think I finally figured out the problem, and it's operator-headspace. Takes two or more series and multiplies their points. Draws servers with low disk space, and servers with highly deviant disk space, but never the same series twice. (This is at least the behavior with 7.0+ and default data sources. 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. percentileOfSeries returns a single series which is composed of the n-percentile This is an alias for highest with aggregation max. Set Max per row to tell Grafana how many panels per row you want If the value is zero, draw the line at 0. Note: Only text and Draws a 0 line when server metric does not exist. stored at an offset. should use the consolidateBy() function with the same function *CA$/ ? You can use regex in the influxdb query as well to filter, or the regex option in grafana. map: While the regex stage would then parse the value for time in the extracted map to your account, In the template variable editor, I'd like to have the ability to have a query like stats.gauges.mycompany.instance. This would only display interfaces which has a peak throughput higher than 1000 packets/min.
