=== Ack Watch API
{xpack-ref}/actions.html#actions-ack-throttle[Acknowledging a watch] enables you
to manually throttle execution of the watch's actions. An action's
_acknowledgement state_ is stored in the `status.actions.<id>.ack.state`
structure.
[float]
==== Request
`PUT _xpack/watcher/watch/<watch_id>/_ack` +
`PUT _xpack/watcher/watch/<watch_id>/_ack/<action_id>`
[float]
==== Path Parameters
`action_id`::
(list) A comma-separated list of the action IDs to acknowledge. If you omit
this parameter, all of the actions of the watch are acknowledged.
`watch_id` (required)::
(string) Identifier for the watch.
[float]
==== Authorization
You must have `manage_watcher` cluster privileges to use this API. For more
information, see {xpack-ref}/security-privileges.html[Security Privileges].
[float]
==== Examples
To demonstrate let's create a new watch:
[source,js]
--------------------------------------------------
PUT _xpack/watcher/watch/my_watch
{
"trigger": {
"schedule": {
"hourly": {
"minute": [ 0, 5 ]
}
}
},
"input": {
"simple": {
"payload": {
"send": "yes"
}
}
},
"condition": {
"always": {}
},
"actions": {
"test_index": {
"throttle_period": "15m",
"index": {
"index": "test",
"doc_type": "test2"
}
}
}
}
--------------------------------------------------
// CONSOLE
// TESTSETUP
The current status of a watch and the state of its actions is returned with the
watch definition when you call the <<watcher-api-get-watch, Get Watch API>>:
[source,js]
--------------------------------------------------
GET _xpack/watcher/watch/my_watch
--------------------------------------------------
// CONSOLE
The action state of a newly-created watch is `awaits_successful_execution`:
[source,js]
--------------------------------------------------
{
"found": true,
"_version": 1,
"_id": "my_watch",
"status": {
"version": 1,
"actions": {
"test_index": {
"ack": {
"timestamp": "2015-05-26T18:04:27.723Z",
"state": "awaits_successful_execution"
}
}
},
"state": ...
},
"watch": ...
}
--------------------------------------------------
// TESTRESPONSE[s/"state": \.\.\./"state": "$body.status.state"/]
// TESTRESPONSE[s/"watch": \.\.\./"watch": "$body.watch"/]
// TESTRESPONSE[s/"timestamp": "2015-05-26T18:04:27.723Z"/"timestamp": "$body.status.actions.test_index.ack.timestamp"/]
When the watch executes and the condition matches, the value of the `ack.state`
changes to `ackable`. Let's force execution of the watch and fetch it again to
check the status:
[source,js]
--------------------------------------------------
POST _xpack/watcher/watch/my_watch/_execute
{
"record_execution" : true
}
GET _xpack/watcher/watch/my_watch
--------------------------------------------------
// CONSOLE
// TEST[continued]
and the action is now in `ackable` state:
[source,js]
--------------------------------------------------
{
"found": true,
"_id": "my_watch",
"_version": 2,
"status": {
"version": 2,
"actions": {
"test_index": {
"ack": {
"timestamp": "2015-05-26T18:04:27.723Z",
"state": "ackable"
},
"last_execution" : {
"timestamp": "2015-05-25T18:04:27.723Z",
"successful": true
},
"last_successful_execution" : {
"timestamp": "2015-05-25T18:04:27.723Z",
"successful": true
}
}
},
"state": ...,
"execution_state": "executed",
"last_checked": ...,
"last_met_condition": ...
},
"watch": ...
}
--------------------------------------------------
// TESTRESPONSE[s/"state": \.\.\./"state": "$body.status.state"/]
// TESTRESPONSE[s/"watch": \.\.\./"watch": "$body.watch"/]
// TESTRESPONSE[s/"last_checked": \.\.\./"last_checked": "$body.status.last_checked"/]
// TESTRESPONSE[s/"last_met_condition": \.\.\./"last_met_condition": "$body.status.last_met_condition"/]
// TESTRESPONSE[s/"timestamp": "2015-05-26T18:04:27.723Z"/"timestamp": "$body.status.actions.test_index.ack.timestamp"/]
// TESTRESPONSE[s/"timestamp": "2015-05-25T18:04:27.723Z"/"timestamp": "$body.status.actions.test_index.last_execution.timestamp"/]
Now we can acknowledge it:
[source,js]
--------------------------------------------------
PUT _xpack/watcher/watch/my_watch/_ack/test_index
GET _xpack/watcher/watch/my_watch
--------------------------------------------------
// CONSOLE
// TEST[continued]
[source,js]
--------------------------------------------------
{
"found": true,
"_id": "my_watch",
"_version": 3,
"status": {
"version": 3,
"actions": {
"test_index": {
"ack": {
"timestamp": "2015-05-26T18:04:27.723Z",
"state": "acked"
},
"last_execution" : {
"timestamp": "2015-05-25T18:04:27.723Z",
"successful": true
},
"last_successful_execution" : {
"timestamp": "2015-05-25T18:04:27.723Z",
"successful": true
}
}
},
"state": ...,
"execution_state": "executed",
"last_checked": ...,
"last_met_condition": ...
},
"watch": ...
}
--------------------------------------------------
// TESTRESPONSE[s/"state": \.\.\./"state": "$body.status.state"/]
// TESTRESPONSE[s/"watch": \.\.\./"watch": "$body.watch"/]
// TESTRESPONSE[s/"last_checked": \.\.\./"last_checked": "$body.status.last_checked"/]
// TESTRESPONSE[s/"last_met_condition": \.\.\./"last_met_condition": "$body.status.last_met_condition"/]
// TESTRESPONSE[s/"timestamp": "2015-05-26T18:04:27.723Z"/"timestamp": "$body.status.actions.test_index.ack.timestamp"/]
// TESTRESPONSE[s/"timestamp": "2015-05-25T18:04:27.723Z"/"timestamp": "$body.status.actions.test_index.last_execution.timestamp"/]
Acknowledging an action throttles further executions of that action until its
`ack.state` is reset to `awaits_successful_execution`. This happens when the
condition of the watch is not met (the condition evaluates to `false`).
You can acknowledge multiple actions by assigning the `actions` parameter a
comma-separated list of action ids:
[source,js]
--------------------------------------------------
POST _xpack/watcher/watch/my_watch/_ack/action1,action2
--------------------------------------------------
// CONSOLE
To acknowledge all of the actions of a watch, simply omit the `actions`
parameter:
[source,js]
--------------------------------------------------
POST _xpack/watcher/watch/my_watch/_ack
--------------------------------------------------
// TEST[s/^/POST _xpack\/watcher\/watch\/my_watch\/_execute\n{ "record_execution" : true }\n/]
// CONSOLE
The response looks like a get watch response, but only contains the status:
[source,js]
--------------------------------------------------
{
"status": {
"state": {
"active": true,
"timestamp": "2015-05-26T18:04:27.723Z"
},
"last_checked": "2015-05-26T18:04:27.753Z",
"last_met_condition": "2015-05-26T18:04:27.763Z",
"actions": {
"test_index": {
"ack" : {
"timestamp": "2015-05-26T18:04:27.713Z",
"state": "acked"
},
"last_execution" : {
"timestamp": "2015-05-25T18:04:27.733Z",
"successful": true
},
"last_successful_execution" : {
"timestamp": "2015-05-25T18:04:27.773Z",
"successful": true
}
}
},
"execution_state": "executed",
"version": 2
}
}
--------------------------------------------------
// TESTRESPONSE[s/"last_checked": "2015-05-26T18:04:27.753Z"/"last_checked": "$body.status.last_checked"/]
// TESTRESPONSE[s/"last_met_condition": "2015-05-26T18:04:27.763Z"/"last_met_condition": "$body.status.last_met_condition"/]
