REST API Examples

new in release v2.24

Thruk offers a rest api to expose various aspects of Thruk itself and livestatus information.

Read more about the REST API itself. This page contains some useful reallife examples.

Simple Host List

Fetch list of all host names:

  %> thruk r /csv/hosts?columns=name

or by curl:

  %> curl -g 'http://user:password@localhost/thruk/r/csv/hosts?columns=name'

Notifications Per Hour Group by Site

List total number of notifications send in the last 60 minutes grouped by backend name:

  %> thruk r '/notifications?time[gt]=-60m&columns=count(*):notifications_per_hour,peer_name'

Sending Commands

Add Service Downtime

Putting a service into downtime can be done by either the thruk cli tool:

  %> thruk r -d "start_time=now" -d "end_time=+60m" -d "comment_data='downtime comment'" '/services/<host>/<svc>/cmd/schedule_svc_downtime'

or by sending a http request, for example with curl:

  %> curl -d "start_time=now" -d "end_time=+60m" -d "comment_data='downtime comment'" http://0:3000/thruk/r/services/<host>/<svc>/cmd/schedule_svc_downtime

Note that you don’t have to set all parameters, only the required ones are necessary. You can use relative arguments for the start- and end-time. For example now will be replaced with the current timestamp while +60m will be 60 minutes in the future.

Read more about relative timestamps.

start_time is optional and will be set to the current timestamp.

end_time is optional as well and will be set to the default downtime_duration.

This leaves a single required argument with the downtime comment:

  %> curl -d "comment_data='downtime comment'" http://0:3000/thruk/r/services/<host>/<svc>/cmd/schedule_svc_downtime

Send Any Command

To avoid escaping issues, there is a generic command endpoint /cmd which can be used to send any command.

    %> curl -H "X-Thruk-Auth-Key: ****" \
            -d "cmd=acknowledge_svc_problem" \
            -d "host=hostname" \
            -d "service=servicedescription" \
            -d "comment_data=test" \
          'http://localhost/thruk/r/cmd'

Grouping

List sessions which had been active within the last 10minutes:

  %> thruk r '/thruk/sessions?columns=username,max(active)&active[gte]=-10m'

Create new Host Object

To create objects via the config tool you can use the generic /config/objects endpoint like this:

    %> curl -H "X-Thruk-Auth-Key: ****" \
            -X POST \
            --header "Content-Type: application/json" \
            -d '{":TYPE": "host", ":FILE":"testhosts.cfg","name":"testhost123"}' \
            http://localhost/thruk/r/config/objects
