Here are two query examples: PostgreSQL. SELECT hostname FROM host WHERE region IN($region) PromQL. query_result(max_over_time(<metric>[${__range_s}s]) != <state>) For more information about writing a query for your data source, refer to the specific Grafana data source documentation. Query tab UI. The Query tab consists of the following elements:

Add annotation queries using the Annotations view in the Dashboard menu. An example query: SELECT title, description from events WHERE $timeFilter ORDER BY time ASC For InfluxDB, you need to enter a query like the one in the example above. The where $timeFilter component is required. If you only select one column, then you do not need to enter anything in the column mapping fields.

InfluxDB query guide. ... There are currently two separate datasources for InfluxDB in Grafana: InfluxDB 0.8.x and InfluxDB 0.9.x. ... For example:.

When the Multi-value or Include all value options are enabled, Grafana converts the labels from plain text to a regex compatible string. Which means you have to use =~ instead of =. Example dashboard: InfluxDB Templated Dashboard Query variables If you add a query template variable, then you can write an InfluxDB exploration (metadata) query.

Organization: Your InfluxDB organization name or ID.. Token: Your InfluxDB API token.. Default Bucket: The default bucket to use in Flux queries.. Min time interval: The Grafana minimum time interval.. Click Save & Test.Grafana attempts to connect to the InfluxDB 2.1 datasource and returns the results of the test.

For InfluxDB, you need to enter a query like the one in the example above. The where $timeFilter component is required. If you only select one column, then you do not need to enter anything in the column mapping fields. The Tags field can be a comma-separated string.

For example: InfluxDB-InfluxQL; InfluxDB-Flux. InfluxQL (classic InfluxDB query). These options apply if you are using the InfluxQL query ...

Jul 16, 2020 · Do more in your Grafana dashboard queries. With Grafana 7.1, you can create much more powerful queries to populate your dashboard charts, by using Flux queries to do things that just aren’t possible in InfluxQL: Joins, to create graphs that span multiple buckets. For example, you might want a Grafana chart that displays both bytes transferred and requests per second; Flux allows you to query these two measurements and join them into a single table.

For example, you might want a Grafana chart that displays both bytes transferred and requests per second; Flux allows you to query these two ...

May 16, 2018 · I'm using influxdb to store some service metrics. These are simple metrics, such as read bytes or active connections. Then, with grafana, I'm composing some visualizations on top of this. Displaying something as 'read bytes' is quite simple, it's basically summing up values, grouped by a time interval.

Using variables in InfluxDB queries. There are two syntaxes: $<varname> Example: SELECT mean("value") FROM "logins" WHERE "hostname" =~ /^$host$/ AND $timeFilter GROUP BY time($__interval), "hostname" [[varname]] Example: SELECT mean("value") FROM "logins" WHERE "hostname" =~ /^[[host]]$/ AND $timeFilter GROUP BY time($__interval), "hostname"

16.07.2020 · For example, you might want a Grafana chart that displays both bytes transferred and requests per second; Flux allows you to query these two measurements and join them into a single table. Math across measurements, which go beyond simple joins to allow you to do math on columns in the joined table.
