#icingacamp – San Diego – 10/18/2016
ICINGA 2 – APIFY THEM ALL

2. • Michael Friedrich
• Icinga 2 Developer & Community Lead
• Senior Developer @NETWAYS
• 7+ years #icingalove
• @dnsmichi

3. ICINGA 2 - API

4. • HTTP with RESTful Url Schema
• ApiUser config object
• X.509 and/or Basic Auth

5. ApiUser Object
object ApiUser "root" {
password = "icinga”
permissions = [ "*" ]
}

6. ApiUser Permissions
permissions = [
{
permission = "objects/query/Host"
filter = {{ regex("^Linux", host.vars.os) }}
},
{
permission = "objects/query/Service"
filter = {{ regex("^Linux", host.vars.os) }}
}
]

7. • create, modify and delete objects
• query objects and status
• run actions
• subscribe to events
• manage configuration packages

8. • Status, Objects, Actions and Events
• Simple filter
services?service=localhost!ping6
• Advanced filter
type=Service&filter=service.name==%22ping6%22
(Hint: assign where expressions)

9. • Configuration management
• New standard config API
• Support for Packages and Stages
• No more SSH transport, all HTTP
• Used by the Icinga Director

10. • Event Streams
• Based on types
CheckResult, StateChange, Notification, Acknowledgement*, Comment*,
Downtime*
• Use filters
Example: Receive all check results where the state is not OK.
$ curl -k -s -u root:icinga -H 'Accept: application/json' -X POST
'https://192.168.33.5:5665/v1/events'
-d '{ "queue": "mine", "types": [ "CheckResult" ], "filter":
"event.check_result.state != 0" }'
