About this plugin

This is a datasource plugin for integrating Grafana 3.x/4.x and Sensu. It provides a query builder to return data about Events, Results, Aggregates, and Clients.

The query builder provides hints for each type, with two optional dimensions "Client Name" and "Check Name".

Running with Docker

A docker-compose.yml file is provided to easily stand up a Grafana 3.x server with this datasource mapped to the container.

Installation

• Copy/clone this repos into /var/lib/grafana/plugins
• Restarting grafana-server is required to pick up the plugin.

Once the plugin is "feature complete" a PR will be made to add this plugin to the official datasource plugins on Grafana.net

Using the plugin

Setup datasource

And and test datasource by setting the Url to the Sensu API, typically on port 4567.

Using the query builder

Add a new "Table" to a dashboard and select the Sensu datasource. Choosing results, you will get a "dimensions" option to narrow the dataset.

There are 11 options for the datasource:

1. Aggregates: Returns aggregate check states, with 7 different "modes"
2. List
3. Clients
4. Checks
5. Results Critical
6. Results OK
7. Results Unknown
8. Results Warning
9. Check Subscriptions: Returns list of checks associated with a subscription Dimensions

• name - name of check
• aggregate - name of aggregate
• type (metric|check)
• source - JIT client

3. Clients
4. Client History: Similar to Results, but with additional data
   • NOTE: this is a deprecated API but still actively used by Uchiwa
5. Events: Returns active events (alerts)
6. Events as JSON: Returns active events (alerts)
7. Results as JSON: Returns check results in JSON format
8. Results as Table: Returns check results in Table format
9. Sensu Health
10. Silenced Entries
11. Stashes

TODO

source type: client history needs dimension: check_name filter and min/max/current/avg/total selector source type: aggregates, aggregate mode: list need dimension to pick aggregate field “checks/clients/crit/ok/stale/etc” and min/max/current/avg/total selector
