==== Execute Watch API
This API forces the execution of a watch stored in the `.watches` index.
It can be used to test a watch without executing all the actions or by ignoring the condition.
The response contains a `BytesReference` that represents the record that would be written to the `.watch_history` index.
The following example executes a watch with the name `my-watch`
[source,java]
--------------------------------------------------
ExecuteWatchResponse executeWatchResponse = watcherClient.prepareExecuteWatch("my-watch")
// Will execute the actions no matter what the condition returns
.setIgnoreCondition(true)
// A map containing alternative input to use instead of the input result from the watch's input
.setAlternativeInput(new HashMap<String, Object>())
// Trigger data to use (Note that "scheduled_time" is not provided to the ctx.trigger by this
// execution method so you may want to include it here)
.setTriggerData(new HashMap<String, Object>())
// Simulating the "email_admin" action while ignoring its throttle state. Use
// "_all" to set the action execution mode to all actions
.setActionMode("_all", ActionExecutionMode.FORCE_SIMULATE)
// If the execution of this watch should be written to the `.watch_history` index and reflected
// in the persisted Watch
.setRecordExecution(false)
.get()
--------------------------------------------------
Once the response is returned, you can explore it by getting execution record source:
[source,java]
--------------------------------------------------
XContentSource source = executeWatchResponse.getRecordSource();
--------------------------------------------------
The `XContentSource` provides you methods to explore the source:
[source,java]
--------------------------------------------------
Map<String, Object> map = source.getAsMap();
--------------------------------------------------
Or get a specific value associated with a known key:
[source,java]
--------------------------------------------------
String actionId = source.getValue("result.actions.0.id");
--------------------------------------------------
