Hi,
We are currently trying out Icinga2, and have come across a challenge when
using the API to create and delete services.
Here is the high-level flow, all done via the API:
1. Create host, with notification enabled (vars.notification.mail set)
2. Create service for the host. A notification object is created, based
on the standard notification apply rule.
3. Delete the service, with cascade=1
4. List the active notifications, and see that the notification created
via apply rule for the service still exists
We first discovered this problem when trying to create the service again, and
the apply rule for the notification fails because the object already exists.
We also tried to delete the notification object directly via the API, but this
is not allowed because the object has not been created via the API.
If we delete the host via the API, with cascade=1, then all objects are deleted
including the notification object for the service.
So to my question: are we doing something wrong? Or is it a bug when deleting a
service?
Below you will find version information and steps to reproduce on vanilla
installation of icinga2.

Steps to reproduce
===============
On vanilla installation of icinga2:
- yum install icinga2
- icinga2 api setup
Below "request" just wraps call to curl with necessary authentication and
headers:
request PUT objects/hosts/node1 { "templates": [ "generic-host" ], "attrs": {
"address": "192.168.11.20", "check_command": "hostalive", "vars.os" : "Linux",
"vars.notification.mail.users": ["icingaadmin"]} }
{
"results": [
{
"status": "Object was created",
"code": 200
}
]
}
request PUT objects/services/node1!customservice1 { "attrs": { "check_command":
"passive", "enable_active_checks": "0" , "max_check_attempts": "1",
"retry_interval": "0"} }
{
"results": [
{
"status": "Object was created",
"code": 200
}
]
}
request DELETE objects/services/node1!customservice1 { "cascade": "1" }
{
"results": [
{
"type": "Service",
"status": "Object was deleted.",
"name": "node1!customservice1",
"code": 200
}
]
}
request GET objects/notifications
