# REST API ` URL endpoint. `
Each response entry in the results array contains the following attributes:
Attribute | Type | Description
-----------|------------|--------------
name | String | Full object name.
type | String | Object type.
attrs | Dictionary | Object attributes (can be filtered using the URL parameter `attrs`).
joins | Dictionary | [Joined object types](12-icinga2-api.md#icinga2-api-config-objects-query-joins) as key, attributes as nested dictionary. Disabled by default.
meta | Dictionary | Contains `used_by` object references. Disabled by default, enable it using `?meta=used_by` as URL parameter.
#### Object Query Joins `
where the following joins are available:
Object Type | Object Relations (`joins` prefix name)
-------------|------------------------------------------
Service | host, check\_command, check\_period, event\_command, command\_endpoint
Host | check\_command, check\_period, event\_command, command\_endpoint
Notification | host, service, command, period
Dependency | child\_host, child\_service, parent\_host, parent\_service, period
User | period
Zones | parent
Here's an example that retrieves all service objects for hosts which have had their `os`
custom variable set to `Linux`. The result set contains the `display_name` and `check_command`
attributes for the service. The query also returns the host's `name` and `address` attribute
via a join:
```bash
curl -k -s -S -i -u root:icinga 'https://localhost:5665/v1/objects/services?attrs=display_name&attrs=check_command&joins=host.name&joins=host.address&filter=host.vars.os==%22Linux%22&pretty=1'
```
```json
{
"results": [
{
"attrs": {
"check_command": "ping4",
"display_name": "ping4"
},
"joins": {
"host": {
"address": "192.168.1.1",
"name": "example.localdomain"
}
},
"meta": {},
"name": "example.localdomain!ping4",
"type": "Service"
},
{
"attrs": {
"check_command": "ssh",
"display_name": "ssh"
},
"joins": {
"host": {
"address": "192.168.1.1",
"name": "example.localdomain"
}
},
"meta": {},
"name": "example.localdomain!ssh",
"type": "Service"
}
]
}
```
> **Tip**
>
> Use [X-HTTP-Method-Override](12-icinga2-api.md#icinga2-api-requests-method-override)
> and pass everything in the request body like this:
```bash
curl -k -s -S -i -u 'root:icinga' -H 'Accept: application/json' \
-H 'X-HTTP-Method-Override: GET' -X POST \
'https://localhost:5665/v1/objects/services' \
-d '{ "attrs": [ "display_name", "check_command" ], "joins": [ "host.name", "host.address" ], "filter": "host.vars.os==\"Linux\"", "pretty": true }'
```
In case you want to fetch all [comments](09-object-types.md#objecttype-comment)
for hosts and services, you can use the following query URL (similar example
for downtimes):
```
https://localhost:5665/v1/objects/comments?joins=host&joins=service
```
This is another example for listing all service objects which are unhandled problems (state is not OK
and no downtime or acknowledgement set). We're using [X-HTTP-Method-Override](12-icinga2-api.md#icinga2-api-requests-method-override)
here because we want to pass all query attributes in the request body.
```bash
curl -k -s -S -i -u root:icinga -H 'Accept: application/json' \
-H 'X-HTTP-Method-Override: GET' -X POST \
'https://127.0.0.1:5665/v1/objects/services' \
-d '{ "joins": [ "host.name", "host.address" ], "attrs": [ "name", "state", "downtime_depth", "acknowledgement" ], "filter": "service.state != ServiceOK && service.downtime_depth == 0.0 && service.acknowledgement == 0.0", "pretty": true }'
```
```json
{
"results": [
{
"attrs": {
"acknowledgement": 0.0,
"downtime_depth": 0.0,
"name": "10807-service",
"state": 3.0
},
"joins": {
"host": {
"address": "",
"name": "10807-host"
}
},
"meta": {},
"name": "10807-host!10807-service",
"type": "Service"
}
]
}
```
In order to list all acknowledgements without expire time, you query the `/v1/objects/comments`
URL endpoint with `joins` and `filter` request parameters using the [X-HTTP-Method-Override](12-icinga2-api.md#icinga2-api-requests-method-override)
method:
```bash
curl -k -s -S -i -u root:icinga -H 'Accept: application/json' \
-H 'X-HTTP-Method-Override: GET' -X POST \
'https://localhost:5665/v1/objects/comments' \
-d '{ "joins": [ "service.name", "service.acknowledgement", "service.acknowledgement_expiry" ], "attrs": [ "author", "text" ], "filter": "service.acknowledgement!=0 && service.acknowledgement_expiry==0", "pretty": true }'
```
```json
{
"results": [
{
"attrs": {
"author": "icingaadmin",
"text": "maintenance work"
},
"joins": {
"service": {
"__name": "example.localdomain!disk /",
"acknowledgement": 1.0,
"acknowledgement_expiry": 0.0
}
},
"meta": {},
"name": "example.localdomain!disk /!example.localdomain-1495457222-0",
"type": "Comment"
}
]
}
```
### Creating Config Objects |String | **Optional.** The performance data as array of strings. The raw performance data string can be used too.
check\_command | Array|String | **Optional.** The first entry should be the check commands path, then one entry for each command line option followed by an entry for each of its argument. Alternativly a single string can be used.
check\_source | String | **Optional.** Usually the name of the `command_endpoint`
execution\_start | Timestamp | **Optional.** The timestamp where a script/process started its execution.
execution\_end | Timestamp | **Optional.** The timestamp where a script/process ended its execution. This timestamp is used in features to determine e.g. the metric timestamp.
ttl | Number | **Optional.** Time-to-live duration in seconds for this check result. The next expected check result is `now + ttl` where freshness checks are executed.
In addition to these parameters a [filter](12-icinga2-api.md#icinga2-api-filters) must be provided. The valid types for this action are `Host` and `Service`.
Example for the service `passive-ping`:
```bash
curl -k -s -S -i -u root:icinga -H 'Accept: application/json' \
-X POST 'https://localhost:5665/v1/actions/process-check-result' \
-d '{ "type": "Service", "filter": "host.name==\"icinga2-master1.localdomain\" && service.name==\"passive-ping\"", "exit_status": 2, "plugin_output": "PING CRITICAL - Packet loss = 100%", "performance_data": [ "rta=5000.000000ms;3000.000000;5000.000000;0.000000", "pl=100%;80;100;0" ], "check_source": "example.localdomain", "pretty": true }'
```
```json
{
"results": [
{
"code": 200.0,
"status": "Successfully processed check result for object 'icinga2-master1.localdomain!passive-ping'."
}
]
}
```
You can avoid URL encoding of white spaces in object names by using the `filter` attribute in the request body.
Example for using the `Host` type and filter by the host name:
```bash
curl -k -s -S -i -u root:icinga -H 'Accept: application/json' \
-X POST 'https://localhost:5665/v1/actions/process-check-result' \
-d '{ "filter": "host.name==\"example.localdomain\"", "type": "Host", "exit_status": 1, "plugin_output": "Host is not available." }'
```
> **Note**
>
> Multi-line plugin output requires the following format: The first line is treated as `short` plugin output corresponding
> to the first line of the plugin output. Subsequent lines are treated as `long` plugin output. Please note that the
> performance data is separated from the plugin output and has to be passed as `performance_data` attribute.
