Thruk Grafana Datasource - a Grafana backend datasource using Thruks REST API


Search for thruk in the Grafana plugins directory or simply use the grafana-cli command:

grafana-cli plugins install sni-thruk-datasource

Also OMD-Labs comes with this datasource included, so if you use OMD-Labs, everything is setup already.

Otherwise follow these steps:

%> cd var/grafana/plugins
%> git clone
%> restart grafana

Create Datasource

Direct access and proxy datasources are possible. Add a new datasource and select:

Variant A:

Uses the Grafana proxy. Must have a local user which is used for all queries.

- Type 'Thruk'
- Url 'https://localhost/sitename/thruk'
- Access 'proxy'
- Basic Auth 'True'
- User + Password for local thruk user

Variant B:

Uses direct access. Thruk must be accessible from the public.

- Type 'Thruk'
- Url 'https://yourhost/sitename/thruk' (Note: this has to be the absolute url)
- Access 'direct'
- Http Auth 'With Credentials'

Table Queries

Using the table panel, you can display most data from the rest api. However only text and numbers can be displayed in a sane way.

Variable Queries

Thruks rest api can be used to fill grafana variables. For example to get all hosts of a certain hostgroup, use this example query:

  SELECT name FROM hosts WHERE groups >= 'linux'

Annotation Queries

Annotation queries can be used to add logfile entries into your graphs. Please note that annotations are shared across all graphs in a dashboard.

It is important to append the time filter like in this example:

  SELECT time, message FROM logs WHERE host_name = 'test' and time = $time

Using Variables

Dashboard variables can be used in almost all queries. For example if you define a dashboard variable named host you can then use $host in your queries.

There is a special syntax for time filter: field = $time which will be replaced by (field >= starttime AND field <= endtime). This can be used to reduce results to the dashboards timeframe.

  SELECT time, message FROM /hosts/$host/alerts WHERE time = $time

which is the same as

  SELECT time, message FROM /alerts WHERE host_name = "$host" AND time = $time
