Sensu Go Data Source for Grafana

Setup | Using the Sensu Go Data Source | Contributing | Code of conduct

Sensu Go Data Source is a Grafana plugin that allows Grafana to connect to the Sensu API. You can use the Sensu Go Data Source to customize your monitoring dashboards with information about Sensu entities and events.


1. Identify release

Grab the URL for the latest release zip file.

2. Add to Grafana

  1. Use grafana-cli to install the plugin by providing the plugin zip URL as the value of the --pluginUrl flag:
$ sudo grafana-cli --pluginUrl plugins install sensu-sensugo-datasource
installing sensu-sensugo-datasource @ 
from url:
into: /var/lib/grafana/plugins

✔ Installed sensu-sensugo-datasource successfully 

Restart grafana after installing plugins . <service grafana-server restart>
  1. Restart grafana-server to enable the data source plugin.

3. Configure

In Grafana, select Configuration and Data Sources from the side menu. Select Add data source, and choose Sensu Go.

To configure the Sensu Go Data Source:

  • Add your Sensu backend API URL (default: http://localhost:8080). When connecting to a Sensu cluster, connect to any single backend in the cluster. For more information about configuring the Sensu API URL, see the Sensu docs.
  • Check the option for Basic Auth.
  • Add a Sensu username and password with get and list permissions for entities, events, and namespaces (default admin user: username admin, password P@ssw0rd!). For more information about creating a Sensu cluster role, see the Sensu docs.

Select Save & Test. You should see a banner confirming that Grafana is connected to Sensu Go.

Using the Sensu Go Data Source

To build a query, select the Sensu Go data source and the Entity, Events, or Namespaces API. See the Sensu docs to learn about available attributes for entities, events, and namespaces. To learn more about building dashboards, see the Grafana docs.

The Sensu Go Data Source supports query strings with the structure:

QUERY API (entity|events|namespaces) [IN NAMESPACE (namespace)] SELECT (field-key) [WHERE (field-key)(=|!=|=~|!~|<|>)(field-value) [AND (field-key)(=|!=|=~|!~|<|>)(field-value)]] [LIMIT (limit)]

Note: Query keywords are case sensitive.

You can use IN NAMESPACE with the entity and events APIs to restrict queries to a specified namespace. When omitted, IN NAMESPACE defaults to the default namespace.

For example, the following query returns hostnames containing the string webserver within the default namespace:

QUERY API entity SELECT system.hostname WHERE system.hostname=~/webserver/

The following query returns 100 entity hostnames with active, non-OK events within the ops namespace:

QUERY API events IN NAMESPACE ops SELECT entity.system.hostname WHERE check.status>0 LIMIT 100

The following query returns all namespaces with names starting with x:

QUERY API namespaces SELECT name WHERE name=~/^x/


Local development

This project requires npm.

To install required dependencies:

npm install

To build the project:

npm run build

You can run npm run watch to start a watch server which rebuilds the source files when a change is detected. The built files are located in the dist directory. For an easier development workflow, link the dist directory into Grafana's plugin directory, so Grafana always has the latest version available.

Releasing and bundling

This project uses the release-it plugin to create release bundles: zip archives ready for mounting into Grafana or using in combination with Grafana's provisioning mechanisms.

To create a release bundle, ensure release-it is installed:

npm install --global release-it

To build a release bundle:

release-it [--no-git.requireCleanWorkingDir]

Running release-it creates a releases directory containing the built zip archive.

You can’t perform that action at this time.
