|
==== Execution
|
||
|
|
|
||
|
|
{xpack-ref}/actions.html#actions-ack-throttle[Acknowledging a watch] enables you
|
||
|
|
to manually throttle execution of a watch's actions. A watch can be acknowledged
|
||
|
|
through the following request:
|
||
|
|
|
||
|
|
["source","java",subs="attributes,callouts,macros"]
|
||
|
|
--------------------------------------------------
|
||
|
|
include-tagged::{doc-tests}/WatcherDocumentationIT.java[ack-watch-execute]
|
||
|
|
--------------------------------------------------
|
||
|
|
<1> The ID of the watch to ack.
|
||
|
|
<2> An optional list of IDs representing the watch actions that should be acked.
|
||
|
|
If no action IDs are provided, then all of the watch's actions will be acked.
|
||
|
|
|
||
|
|
[[java-rest-high-watcher-ack-watch-response]]
|
||
|
|
==== Response
|
||
|
|
|
||
|
|
The returned `AckWatchResponse` contains the new status of the requested watch:
|
||
|
|
|
||
|
|
["source","java",subs="attributes,callouts,macros"]
|
||
|
|
--------------------------------------------------
|
||
|
|
include-tagged::{doc-tests}/WatcherDocumentationIT.java[ack-watch-response]
|
||
|
|
--------------------------------------------------
|
||
|
|
<1> The status of a specific action that was acked.
|
||
|
|
<2> The acknowledgement state of the action. If the action was successfully
|
||
|
|
acked, this state will be equal to `AckStatus.State.ACKED`.
|
||
|
|
|
||
|
|
[[java-rest-high-watcher-ack-watch-async]]
|
||
|
|
==== Asynchronous Execution
|
||
|
|
|
||
|
|
This request can be executed asynchronously:
|
||
|
|
|
||
|
|
["source","java",subs="attributes,callouts,macros"]
|
||
|
|
--------------------------------------------------
|
||
|
|
include-tagged::{doc-tests}/WatcherDocumentationIT.java[ack-watch-execute-async]
|
||
|
|
--------------------------------------------------
|
||
|
|
<1> The `AckWatchRequest` to execute and the `ActionListener` to use when
|
||
|
|
the execution completes.
|
||
|
|
|
||
|
|
The asynchronous method does not block and returns immediately. Once the request
|
||
|
|
completes, the `ActionListener` is called back using the `onResponse` method
|
||
|
|
if the execution successfully completed or using the `onFailure` method if
|
||
|
|
it failed.
|
||
|
|
|
||
|
|
A listener for `AckWatchResponse` can be constructed as follows:
|
||
|
|
|
||
|
|
["source","java",subs="attributes,callouts,macros"]
|
||
|
|
--------------------------------------------------
|
||
|
|
include-tagged::{doc-tests}/WatcherDocumentationIT.java[ack-watch-execute-listener]
|
||
|
|
--------------------------------------------------
|
||
|
|
<1> Called when the execution is successfully completed. The response is
|
||
|
|
provided as an argument.
|
||
|
|
<2> Called in case of failure. The raised exception is provided as an argument.
