A log stream is a novel supply of log content, such as a file. A more granular log stream selector then reduces the variety of searched streams to a manageable quantity. This implies that the labels handed to the log stream selector will affect grafana developer the relative performance of the query’s execution. Line filter expressions are the fastest way to filter logs as soon as the log stream selectors have been utilized. All log streams that have each a label of app whose value is mysql

  • Each expression can filter out, parse, or mutate log traces and their respective labels.
  • See template capabilities to learn about out there features within the template format.
  • We support multiple value varieties which are mechanically inferred from the query input.
  • Formats variables with multiple values as a comma-separated string.
  • Label filters may be place anyplace in a log pipeline.

Label filter expressions are the one expression allowed after the unwrap expression. This is especially to permit filtering errors from the metric extraction. If the conversion of the label worth fails, the log line isn’t filtered and an __error__ label is added.

Parser Expression

See template features to study out there functions within the template format. The unpack parser parses a JSON log line, unpacking all embedded labels from Promtail’s pack stage. A particular property _entry will also be used to exchange the original log line.

interpolation, the variable worth might be escaped so as to conform to the syntax of the query language and where it is used. For example, a variable utilized in a regex expression in an InfluxDB or Prometheus question shall be regex escaped. Read the information source particular documentation topic for particulars on worth escaping during interpolation.


Formats variables with a quantity of values right into a pipe-separated string. Formats variables with multiple values in customized format for OpenTSDB. Formats variables with a number of values in Lucene format for Elasticsearch. Before queries are despatched to your information supply the question is interpolated, that means the variable is replaced with its present worth. During

with (?i). This full question example will give outcomes that embrace the string error, and don’t include the string timeout. Formats single- and multi-valued variables right into a comma-separated string, escapes ‘ in each value by ” and quotes every worth with ‘. Formats single- and multi-valued variables into a comma-separated string, escapes ‘ in each value by \’ and quotes each value with ‘. Formats variables with a quantity of values right into a glob (for Graphite queries).

Lets you set the minimum value utilized in proportion threshold calculations. Will extract and rewrite the log line to only accommodates the question and the length of a request. A predicate incorporates a label identifier, an operation and a price to compare the label with.

A area can characterize a single time collection or table column. The | hold expression will maintain solely the desired labels in the pipeline and drop all the opposite labels. You can mix the unpack and json parsers (or another parsers) if the original embedded log line is of a selected format. Captures are matched from the road starting or the previous set of literals, to the line end or the following set of literals. If a seize is not matched, the pattern parser will stop.

Drop Labels Expression

Visit the Grafana developer portal for instruments and sources for extending Grafana with plugins. The shade choices and their effect on the visualization depends on the visualization you are working with. You can use the unit dropdown to additionally specify customized units, customized prefix or suffix and date time formats. Most area options won’t have an effect on the visualization until you click on exterior of the sphere choice box you are enhancing or press Enter. The data model utilized in Grafana, specifically the data body, is a columnar-oriented desk construction that unifies both time sequence and desk query outcomes. Each column inside this structure is known as a area.

Formats variables with a quantity of values as a comma-separated string. You can chain a quantity of predicates utilizing and and or which respectively specific the and and or binary operations. And could be equivalently expressed by a comma, an area or one other pipe. Label filters may be place anyplace in a log pipeline. Formats variables with multiple values right into a regex string.

If you wish to disable this habits, you probably can toggle off the Scale models change. Grafana can sometimes be too aggressive in parsing strings and displaying them as numbers. To configure Grafana to show the original string worth, create a subject override and add a unit property with the String unit. For a whole record of field formatting choices, check with Standard choices definitions.

This part explains all available normal choices. We assist multiple worth sorts which are mechanically inferred from the question input. If any invalid formatting option is specified, then glob is the default/fallback option. When in Flow mode, the grafana-agent binary exposes a command-line interface with subcommands to carry out various operations. I can’t just chose to switch all comma in the csv into semicolon as a result of it will broke some information.

Optionally, the log stream selector may be followed by a log pipeline. A log pipeline is a set of stage expressions which would possibly be chained together and applied to the selected log streams. Each expression can filter out, parse, or mutate log lines and their respective labels. A log pipeline may be appended to a log stream selector to additional process and filter log streams. Each expression is executed in left to right sequence for each log line. If an expression filters out a log line, the pipeline will cease processing the current log line and begin processing the subsequent log line.

To filters those errors see the pipeline errors section. The string kind is the only one that can filter out a log line with a label __error__. Switch to case-insensitive matching by prefixing the regular expression

The common expression should include a least one named sub-match (e.g (?Pre)), every sub-match will extract a unique label. A sample expression is composed of captures and literals. It’s multi function column but the knowledge is separated with a comma that will give me problem with other information. Enter what Grafana ought to show if the sector worth is empty or null. Click within the Unit field, then drill down till you find the unit you need. The unit you select is utilized to all fields except time.

Scale Models

Formats single- and multi-valued variables right into a comma-separated string, escapes ” in each value by \” and quotes every value with “. By default the calculated min and max might be primarily based on the minimum and maximum, in all series and fields. Turning area min/max on, will calculate the min or max on each area individually, based on the minimal or most worth of the field. By default, Grafana mechanically scales the unit primarily based on the magnitude of the worth. For example, if you have a price of zero.14 kW, Grafana will display it as 140 W. Another example is that 3000 kW might be displayed at 3 MW.

The sample parser permits the explicit extraction of fields from log strains by defining a sample expression (| sample “”). You can forcefully override the original label utilizing a label formatter expression. However, if an extracted key seems twice, solely the primary label value might be saved. You can apply normal options to most built-in Grafana panels. Some older panels and community panels that have not up to date to the model new panel and data mannequin will be missing both all or some of these area options. The identical guidelines that apply for Prometheus Label Selectors apply for Grafana Loki log stream selectors.

You can specify a single colour, or select a steady (gradient) shade schemes, primarily based on a price. Continuous shade interpolates a color utilizing the percentage of a worth relative to min and max. Lets you set the utmost worth used in share threshold calculations.
