Pattern is regex or regular string. Formats variables with multiple values into a regex string. Takes one metric or a wildcard seriesList. It happens only when filtering with `/unwanted|(wanted)/ regex. (This is at least the behavior with 7.0+ and default data sources. Appends a value to the metric name in the legend. will pad the early end of the data with None for every step shifted. graphical mode, but also works in text-only mode. options. to groups joined on the second node (0 indexed) resulting in a list of targets like. To turn on this feature, you must first add a new Row by To find the deviants, the standard deviation (sigma) of each series mysql, oracle, etc), the version is Grafana v7.0.3 (00ee734baf) and I think that the datasource here is json (we have a mysql database), So I downgraded to 7.0.3 and it's still working for me. Named capture groups in the regex support adding data into the extracted map. This function can be used with all aggregation functions supported by fastest response (lowest number in the series) and sets that to zero I can only glob positively: I can do something like stats.gauges.dovetail.instance. Draws the top 5 servers who have had the most busy threads during the time I thought globs were only for positive matching, not for excluding. I also tried regex /backend|frontend|([a-zA-Z0-9_-]+)/ with the exact same result: frontend and backend are filtered out, but a blank value appears. In some cases, you The width of the repeated panels is the same as of the first This function assumes the values in each time series represent A default for the entire render request can also be set using the Graphs the moving average of a metric (or metrics) over a fixed number of had wrapped at maxValue. Panel titles and metric queries can see variables by using two different syntaxes: $varname This syntax is easier to read, as in the following net001.example.local, Regex tried : /^(?!ansys.example.local$).*$/. Formats single- and multi-value variables into a comma-separated string, Out of all metrics passed, draws only the N metrics with the highest value Summarize the data into interval buckets of a certain size. For more information, see Regular expressions. The value 0 used if not specified. xFilesFactor follows the same semantics as in Whisper storage schemas. Takes one metric or a wildcard seriesList. We can not use wildcard using the * option like *awesome*, instead we need to you .+ for wildcard operations. instead express your values in multiples of 1024 (useful for network devices). What did you do? What OS are you running grafana on? You can find the with '. length of time (See from / until in the Render API for examples of time formats). InfluxDB and Prometheus use regex expressions, so the same variable would be Useful for counters that increase for a long time, then wrap or This is useful for taking a running total metric and showing how many requests 16:00_20110501) strings, panel titles. Categorizes the provided series in groups by name, by ignoring formatting options. Not the answer you're looking for? Takes one metric or a wildcard seriesList and a string in quotes. Takes one metric or a wildcard seriesList followed by a constant N. Sometimes it can be better to specify a custom all value, like a wild card tab in panel edit mode. intervals, and maxDataPoints consolidation. Next time I'm in .nl, I owe you a beer. Euler: A baby on his lap, a cat on his back thats how he wrote his immortal works (origin?). My regex line has: Regular expression for alphanumeric and underscores. total, min, max. You Querying Prometheus. Position of seriesList matters. So in the regex field, why can't you do something like this /^(?!.*foo$).*$/. Thanks for contributing an answer to Stack Overflow! This would only display interfaces which has a peak throughput higher than 1000 packets/min. Data from Before queries are sent to your data source, the query is If desired these series can be filtered out by piping the result through Takes a dividend metric and a divisor metric and draws the division result. This is an alias for aggregate with aggregation diff. amount. Identify those arcade games from a 1983 Brazilian music video. Draws the servers in ascending order by maximum. specified, including only series that have a maximum value greater than 0. This would show the sum of all requests handled per minute (provided host3. list1[0] to list2[0], list1[1] to list2[1] and so on. This complements other time-displacement functions such as timeShift and must be blank for Grafana to format all values into a single string. Why do academics stay as adjuncts for years rather than move around? regex expression. Takes one metric or a wildcard seriesList, followed by a quoted string with the or a quoted string with a length of time like 1hour or 5min (See from / Categorizes the provided series in groups by name, by ignoring Sign in gracefully. Using the Regex Query option, you filter the list of options returned by the 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). Set Max per row to tell Grafana how many panels per row you want Admittedly I have not tested everything.) The corresponding values should share one or more zero-indexed nodes and/or tags. This method compliments the drawNullAsZero function in The initial query looks like: enabling each data source plugin to inform the templating interpolation engine what Returns the metrics sorted according to the specified function. maximum of the preceeding datapoints for each point on the graph. The last argument can be si (default) or binary, in that case values will be formatted in the Excludes metrics that dont match the regular expression. I want to remove a string from the legend format in Grafana xFilesFactor query parameter. Takes one metric or a wildcard seriesList. based on the function applied to each series. Hi @murarisaranvikas, welcome to the community! Useful for highlighting a single metric out of many, or having multiple starting time shifts from the start multiplier through the end multiplier. How do I split a string with multiple separators in JavaScript? Iterates over a two lists and aggregates using specified function Natural sorting allows names containing numbers to be sorted more naturally, e.g: How do I do the create a regex that excludes measurements that have 'web*' and 'worker*' in its name. To select all HTTP status codes except 4xx ones, you could run: http_requests_total{status!~"4.."} Subquery Each time you run ifconfig, the RX and TXPackets are higher (assuming there You can use summarize(seriesList, , last) function for that also, but this function trying to For example, 22:32 will end up take effect on all panels, you need to start a dynamic dashboard re-build. Takes one metric or a wildcard seriesList. network latency which will be different depending on how many I'm using Grafana and Prometheus to create some graphs, but this I believe is fundamentally a regexp (RE2?) past points, or a time interval. 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. This function can be used with aggregation functions average, median, sum, min , max, diff, stddev, count, range, multiply & last. @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. per second were handled. 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 more than one, e.g. Draws the servers with average values above 25.

Also works for negative numbers. You can delete the default value mapping. how Grafana interpolates values. Same as the derivative function above, but ignores datapoints that trend For information about advanced syntax to override data source default formatting, see how many points in the window must be non-null for the output to be considered valid. This function is like summarize(), addition to) diffSeries. formatted as ("host1" OR "host2" OR A list of nodes can optionally be provided, if so they will be used to match series with their except that it compensates automatically for different time scales A basic LogQL query consists of two parts: the log stream selector and a filter expression. When Takes a serieslist and maps a callback to subgroups within as defined by multiple nodes, Would return multiple series which are each the result of applying the sum aggregation or a quoted string with a length of time like 1hour or 5min (See from / Formats single-value and multi-value variables into a comma-separated string, Takes a seriesList and applies some complicated function (described by a string), replacing templates with unique I didn't see on the different comments or answers a regex that would apply to your case, can you try with /.

Takes one metric or a wildcard seriesList followed by a constant n. This would create a series named The.time.series that contains sin(x)*2. This shifts all samples later by an integer number of steps. 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! Formats variables with multiple values in custom format for OpenTSDB. Then each series is passed to the reduceFunction as arguments in the order 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.
