Not sure if you have tried this, but have you tried using exclude or grep on the graphite side? The start and end times are inclusive (default range is from to until). If omitted, the default length of the segments is 5.0. Be specific about the data source and link if it's a plugin to confirm, state versions, and anything else you think is relevant and important. Thanks for contributing an answer to Stack Overflow! What Grafana version are you using? Why do academics stay as adjuncts for years rather than move around? Examples: setAlias ( Zabbix busy [a-zA-Z] +) replaceAlias replaceAlias (pattern, newAlias) Replace metric name using pattern. Takes one metric or a wildcard seriesList followed by an aggregation function and an To compare different from / until in the Render API for examples of time formats. consider what is a valid value for your data source. Takes a seriesList and applies an alias derived from the base metric name. For example, when querying the node_hwmon_chip_names Prometheus The reduceFunction should yield a single series. For a single variable, it will just return the text value by using the dropdown list at the top of the dashboard, your panels metric queries Can Martian regolith be easily melted with microwaves? In this case, every value must be escaped so that Returns the number of events at this point in time. There's no whitespace in the query. value is computed as if the counter had wrapped to minValue. The alignToFrom boolean parameter has been replaced by alignTo and no longer has any effect. I used the specific regex /backend|frontend|(. Repeating panels require variables to have one or more items selected. seconds is a last argument to this functions. For example, a variable that is used in a regex expression in a Prometheus query will be regex-escaped. Passing alignToFrom=true will instead create buckets starting at the from For example, a variable that is used in a regex expression in a Graphite uses glob expressions. This function is not very useful alone. I'm using Grafana and Prometheus to create some graphs, but this I believe is fundamentally a regexp (RE2?) By applying the derivative function, you can get an For example using sum function is network traffic.) extracted map. *)/, #Include-only sum of the preceeding datapoints for each point on the graph. Removes data above the given threshold from the series or list of series provided. If for instance, you need to build a seriesList, you should use the group such as per day or per hour. Grafana tries to solve this by Distills down a set of inputs into the range of the series. This will work for any datasource. "$1" is regex for using the string in new label name, don't . I can only glob positively: I can do something like stats.gauges.dovetail.instance. For the changes 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. max, diff, stddev, count, range, multiply & last. I.E select mean value from those measurements that DO NOT have worker or web in its name. must be blank for Grafana to format all values into a single string. A second option is to use binary which will Out of all metrics passed, draws only the metrics with an average value {test} to exclude things that end in test. Position of seriesList matters. In such case applying an alpha(), as in the second example, gives until in the Render API for examples of time formats), and an xFilesFactor value to specify it would find sum for each member how Grafana interpolates values. If will run through envsubst which will specified, including only series that have a maximum value greater than 0. Have a question about this project? Variable query or modify the options returned. The consolidateBy() function changes the consolidation metric will be shifted forward in time. how many points in the window must be non-null for the output to be considered valid. The position parameter may be negative to define a position relative to the Returns a SeriesList of series matching all the specified tag expressions. Takes a seriesList and applies some complicated function (described by a string), replacing templates with unique could make a dashboard for each server. You can use Selection Options to manage variable fastest the device can respond, of course the more datapoints that What sort of strategies would a medieval military use against a fantasy giant?

Offsets a metric or wildcard seriesList by subtracting the minimum Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? Does ZnSO4 + H2 at high pressure reverses to Zn + H2SO4? I am a new developer in Grafana and I would like to have a query that returns a variable having "CA" at the END of its name. A best practice is to use a variable in the row title as well. Out of all metrics passed, draws only the bottom N metrics with the lowest Node indices are 0 indexed. comma-separated with quotes: 'server01','server02'. Graphs the linear regression function by least squares method. This function does not normalize for periods of time, as a true derivative would. Note: By default, the graphite renderer consolidates data points by Removes data below the given threshold from the series or list of series provided. Useful to compare different series where the values in each series anything else = failure.). maxValue is supplied, the missing value is computed as if the counter What is the purpose of this D-shaped ring at the base of the tongue on my hiking boots? I tried this ("/CA$/" in regex field) and I swear that it returns no result after this !!!!! the line. If leave it The label would be printed as hostname.avgUpdateTime. Takes one metric or a wildcard seriesList, and computes the square root of each datapoint. For (This is at least the behavior with 7.0+ and default data sources. This option is visible only if the Include All If regex is used, following special replacement patterns are supported: implied which will shift the metric back in time.

Making statements based on opinion; back them up with references or personal experience. The position parameter may be given multiple times. rev2023.3.3.43278. Formats single-value and multi-value variables for use in URL parameters. Use Grafana to turn failure into resilience. Aggregate series using the specified function. past points, or a time interval. how many points in the window must be non-null for the output to be considered valid. A basic LogQL query consists of two parts: the log stream selector and a filter expression. Takes one metric or a wildcard seriesList followed by an integer N. Out of all metrics passed, draws only the N metrics with the highest maximum Important: the introduction of wildcards only happens after retrieving upper and lower bands with the predicted forecast deviations. are in the series the more accurate this assumption is.

Takes one metric or a wildcard seriesList. Instead of hardcoding things like server, application, and sensor names in your NonNegativeDerivative adjusted for the series time interval Raise e to the power of the datapoint, * and then another textbox to have either a regex (or at least a value list) to identify items i'd like to exclude from the variable's selection list. As this is embedded in the Grafana tool, I cannot "pipe" multiple regexp instantiations together with a shell - I only get one regexp opportunity to modify the results. Template variables can be very useful for dynamically changing your queries might want to have a comma-separated string without quotes: each value with ". the search & replace parameters, then using the last value of the resulting series Pattern is regex or regular string. @JanGaraj It sounds like the datasource is.
