📈🤖 Query Grafana dashboards

Grafana for Hubot

Use Hubot to query Grafana dashboards. Inspired by the work of hubot-graphite and hubot-graphme. Check out the HOWTO to get started with the bot.

Note: This package requires Grafana 2.0.2 or higher.

npm install hubot-grafana --save

Then add hubot-grafana to your external-scripts.json:

HUBOT_GRAFANA_PER_ROOM	No	Allow per room Grafana Host & API key configuration
HUBOT_GRAFANA_QUERY_TIME_RANGE	No	Default time range for queries (defaults to 6h)
HUBOT_GRAFANA_DEFAULT_WIDTH	No	Default width for rendered images (defaults to 1000)
HUBOT_GRAFANA_DEFAULT_HEIGHT	No	Default height for rendered images (defaults to 500)
HUBOT_GRAFANA_DEFAULT_TIME_ZONE	No	Default time zone for rendered images (defaults to "")

^ Not required when HUBOT_GRAFANA_PER_ROOM is set to 1.

^^ Not required for auth.anonymous Grafana configurations. All other authentication models will require a user-specific API key.

Image Hosting Configuration

By default, hubot-grafana will assume you intend to render the image, unauthenticated, directly from your Grafana instance. The limitation is that you will only receive a link to those images, but they won't appear as images in most circumstances in your chat client.

You can use one of the following strategies to host the generated images from Grafana.

• Amazon S3
• Slack
• Rocket.Chat
• Telegram

Example Configuration

export HUBOT_GRAFANA_HOST=http://play.grafana.org
export HUBOT_GRAFANA_API_KEY=abcd01234deadbeef01234
export HUBOT_GRAFANA_QUERY_TIME_RANGE=1h
export HUBOT_GRAFANA_S3_BUCKET=mybucket
export HUBOT_GRAFANA_S3_ACCESS_KEY_ID=ABCDEF123456XYZ
export HUBOT_GRAFANA_S3_SECRET_ACCESS_KEY=aBcD01234dEaDbEef01234
export HUBOT_GRAFANA_S3_PREFIX=graphs

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

If you want to refer to the API Panel ID, use the :panel-<identifier> format to retrieve it. These will not change when the dashboard is re-arranged.

hubot graf db graphite-carbon-metrics:panel-8

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

Per room configuration

When HUBOT_GRAFANA_PER_ROOM is set to '1' the following commands configure the Grafana Host and API key for the room in which the commands are issued.

hubot graf set host http://play.grafana.org
hubot graf set api_key abcd01234deadbeef01234
