Sample Interaction

user1>> hubot graf db graphite-carbon-metrics
hubot>> Graphite Carbon Metrics: http://play.grafana.org/render/dashboard/solo/graphite-carbon-metrics/?panelId=1&width=1000&height=500&from=now-6h - http://play.grafana.org/dashboard/db/graphite-carbon-metrics/?panelId=1&fullscreen&from=now-6h

Grafana Commands

Retrieve a Dashboard

Get all panels in a dashboard. In this example, graphite-carbon-metrics is the slug for the given dashboard.

hubot graf db graphite-carbon-metrics

Retrieve Specific Panels

Get a single panel of a dashboard. In this example, only the third panel would be returned. Note that this is the visual panel ID, counted from top to bottom, left to right, rather than the unique identifier stored with the panel itself.

hubot graf db graphite-carbon-metrics:3

Get all panels matching a particular title (case insensitive) in a dashboard. In this case, only panels containing cpu would be returned.

hubot graf db graphite-carbon-metrics:cpu

Retrieve Dashboards in a Time Window

Specify a time range for the dashboard. In this example, the dashboard would be set to display data from 12 hours ago to now.

hubot graf db graphite-carbon-metrics now-12hr

If you don't want to show the dashboard uptil now, you can add an extra time specification, which will be the to time slot. In this example, the dashboard would be set to display data from 24 hours ago to 12 hours ago.

hubot graf db graphite-carbon-metrics now-24hr now-12hr

You can combine multiple commands in this format as well. In this example, retrieve only the third panel of the graphite-carbon-metrics dashboard with a window of eight days ago to yesterday.

hubot graf db graphite-carbon-metrics:3 now-8d now-1d

Templated Dashboards

Grafana allows dashboards to be set up as templates and accept arguments to generate them through the API. In this example, we get a templated dashboard with the $host parameter set to carbon-a

hubot graf db graphite-carbon-metrics host=carbon-a

Utility Commands

This command retrieves all dashboards and their slugs so they can be used in other commands.

hubot graf list

Dashboards can be tagged for easier reference. In this example, return all dashboards tagged with production.

hubot graf list production

Similarly, you can search the list of dashboards. In this example, return all dashboards that contain the word elb.

hubot graf search elb
