Grafana Support. For example the following template will output the value of the path label: You can take advantage of pipeline to join together multiple functions. Then, we assign it the label of “MTA Bus Route.”. Grafana Labs uses cookies for the normal operation of this website. Examples: Following template variables available for using in setAlias() and replaceAlias() functions: Returns given alias instead of the metric name. // Applied against the extracted node) This would allow one to extract a given node index out of the query, as opposed to always using the last one. Enter your email to receive our newsletter for the latest updates. Signature: min(a interface{}, i ...interface{}) int64. Scalable monitoring system for timeseries data. I’ve used a SQL query in the example, since in practice you often want variables to take on values that aren't hard-coded but that change based on data in the database, such as customer names, cluster names, etc. You can see the Values field has been auto-populated by Grafana once we chose the interval variable type. Create your free account. The values selected in the picker will define what our $route variable will be. 6. The replacement string is substituted directly, without using Expand. Horizontally scalable, multi-tenant log aggregation system inspired by Prometheus. Indeed, all Prometheus metrics are time based data. Signature: replace(old string, new string, src string) string. On y est ! For learning, it might be easier tostart with a couple of examples. In the template variable editor, I'd like to have the ability to have a query like stats. You can also see the change takes place in multiple panels, since they all use the variable, $route in their query. grafana@groups.io; Topic × Close Search. Get a substring from a string. Now, we define a SQL query whose results will define our route variable. The strings.substring() function returns a substring based on start and end parameters. With the following query, you can see the queries that do not use the bind variable and the number of copies of these queries. See a demo of new and updated Loki features so you can learn how to create metrics from logs and alert on your logs with powerful Prometheus-style alerting rules.

Return the smallest of a series of integers. Note: In Loki 2.1 replace (as opposed to Replace) is available with a different signature but easier to chain within pipeline. We could also use a query that’s more advanced, but gives the additional benefit of human readable names rather than using symbols or acronyms: Here, we define four key value pairs to be the set of possible values for our route variable, where the key is the human readable name of the bus type and the value is the letter corresponding to the route type. There are 4 types of bus routes: M, B, S, and Q - corresponding to New York’s boroughs of Manhattan, Brox and Brooklyn, Staten Island and Queens.

For instance, if you have a website that you refer to by the name "some_site" in your systems, but you have an AWS S3 … You can combine multiple functions using pipe. Then, we use Grafana’s threshold settings to assign each bus type to a color: Notice that there are 5 colors - one for each bus route M,B,Q and S, as well as one for routes that don’t fall into those categories.

You’ll find everything from how to create visuals for Prometheus metrics to how to visualize geo-spatial data using a World Map. Note: Added in Loki 2.1. Those of us that work with data often want to make useful dashboards that make it easier for ourselves and other people within our team and organization to make sense and get insight about the data we collect. The hard parsing process in the database will increase when bind variable is not in use. It would be nice if Grafana template variables could have some string manipulations applied. Otherwise, this calls value[start, end]. Use this function to remove given characters from the front or back of a string. Signature: nindent(spaces int,src string) string. If that is all you query you get a bunch of columns back. Supports multiple numbers. Signature: Trim(value, cutset string) string. This could be useful to be able to refer to data about the same thing from various datasources from a variable, where that thing is named slightly differently for technical reasons. Execute Flux queries; Query fields and tags; Group; Sort and limit; Window & aggregate How to create a variable of type Query. Note: In Loki 2.1 trim, trimAll, trimSuffix and trimPrefix have been added with a different signature for better pipeline chaining. This document is meant as a reference. Signature: trunc(start int,end int,value string) string. Prints n - length elements of the array (if only one integer n is passed) or n - m elements of the array (if two integers n and m are passed). Once we’ve modified the query, we save our changes and check if our variable works as expected. TrimLeft and TrimRight are the same as Trim except that it trims only leading and trailing characters respectively. By defining variables, we can control the behavior of graphs within a dashboard flexibly but not hard coded. If start is < 0, this calls value[:end].
