=== Execute Watch API
|
|
|
|
The execute watch API forces the execution of a stored watch. It can be used to
|
|
force execution of the watch outside of its triggering logic, or to simulate the
|
|
watch execution for debugging purposes.
|
|
|
|
The following example executes the `my_watch` watch:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _xpack/watcher/watch/my_watch/_execute
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:my_active_watch]
|
|
|
|
For testing and debugging purposes, you also have fine-grained control on how the
|
|
watch is executed--execute the watch without executing all of its actions or
|
|
alternatively by simulating them. You can also force execution by ignoring the
|
|
watch condition and control whether a watch record would be written to the watch
|
|
history after execution.
|
|
|
|
This API supports the following fields:
|
|
|
|
[cols=",^,^,", options="header"]
|
|
|======
|
|
| Name | Required | Default | Description
|
|
|
|
| `trigger_data` | no | | This structure is parsed as the data of the trigger event
|
|
that will be used during the watch execution
|
|
|
|
| `ignore_condition` | no | false | When set to `true`, the watch execution uses the
|
|
<<condition-always, Always>> Condition. This can also be
|
|
specified as a HTTP parameter.
|
|
|
|
| `alternative_input` | no | null | When present, the watch uses this object as a payload
|
|
instead of executing its own input.
|
|
|
|
| `action_modes` | no | null | Determines how to handle the watch actions as part of the
|
|
watch execution. See <<watcher-api-execute-watch-action-mode, Action Execution Modes>>
|
|
for more information.
|
|
|
|
| `record_execution` | no | false | When set to `true`, the watch record representing the watch
|
|
execution result is persisted to the `.watcher-history`
|
|
index for the current time. In addition, the status of the
|
|
watch is updated, possibly throttling subsequent executions.
|
|
This can also be specified as a HTTP parameter.
|
|
|
|
| `watch` | no | null | When present, this <<watch-definition, watch>> is used
|
|
instead of the one specified in the request. This watch is
|
|
not persisted to the index and record_execution cannot be set.
|
|
|======
|
|
|
|
The following example shows a comprehensive example of executing the `my-watch` watch:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _xpack/watcher/watch/my_watch/_execute
|
|
{
|
|
"trigger_data" : { <1>
|
|
"triggered_time" : "now",
|
|
"scheduled_time" : "now"
|
|
},
|
|
"alternative_input" : { <2>
|
|
"foo" : "bar"
|
|
},
|
|
"ignore_condition" : true, <3>
|
|
"action_modes" : {
|
|
"my-action" : "force_simulate" <4>
|
|
},
|
|
"record_execution" : true <5>
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:my_active_watch]
|
|
<1> The triggered and schedule times are provided.
|
|
<2> The input as defined by the watch is ignored and instead the provided input
|
|
will be used as the execution payload.
|
|
<3> The condition as defined by the watch will be ignored and will be assumed to
|
|
evaluate to `true`.
|
|
<4> Forces the simulation of `my-action`. Forcing the simulation means that
|
|
throttling is ignored and the watch is simulated by {watcher} instead of
|
|
being executed normally.
|
|
<5> The execution of the watch will create a watch record in the watch history,
|
|
and the throttling state of the watch will potentially be updated accordingly.
|
|
|
|
This is an example of the output:

|
|
==== Action Execution Modes
|
|
|
|
Action modes define how actions are handled during the watch execution. There
|
|
are five possible modes an action can be associated with:
|
|
|
|
[options="header"]
|
|
|======
|
|
| Name | Description
|
|
|
|
| `simulate` | The action execution will be simulated. Each action type
|
|
define its own simulation operation mode. For example, The
|
|
<<actions-email, email>> action will create the email that
|
|
would have been sent but will not actually send it. In this
|
|
mode, the action may be throttled if the current state
|
|
of the watch indicates it should be.
|
|
|
|
| `force_simulate` | Similar to the the `simulate` mode, except the action will
|
|
not be throttled even if the current state of the watch
|
|
indicates it should be.
|
|
|
|
| `execute` | Executes the action as it would have been executed if the
|
|
watch would have been triggered by its own trigger. The
|
|
execution may be throttled if the current state of the
|
|
watch indicates it should be.
|
|
|
|
| `force_execute` | Similar to the `execute` mode, except the action will not
|
|
be throttled even if the current state of the watch
|
|
indicates it should be.
|
|
|
|
| `skip` | The action will be skipped and won't be executed nor
|
|
simulated. Effectively forcing the action to be throttled.
|
|
|======
|
|
|
|
You can set a different execution mode for every action by associating the mode
|
|
name with the action id:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _xpack/watcher/watch/my_watch/_execute
|
|
{
|
|
"action_modes" : {
|
|
"action1" : "force_simulate",
|
|
"action2" : "skip"
|
|
}
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:my_active_watch]
|
|
|
|
You can also associate a single execution mode with all the actions in the watch
|
|
using `_all` as the action id:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _xpack/watcher/watch/my_watch/_execute
|
|
{
|
|
"action_modes" : {
|
|
"_all" : "force_execute"
|
|
}
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:my_active_watch]
|
|
|
|
[float]
|
|
[[watcher-api-execute-inline-watch]]
|
|
==== Inline Watch Execution
|
|
|
|
You can use the Execute API to execute watches that are not yet registered by
|
|
specifying the watch definition inline. This serves as great tool for testing
|
|
and debugging your watches prior to adding them to {watcher}.
|
|
|
|
The following example shows how to execute a watch inline:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _xpack/watcher/watch/_execute
|
|
{
|
|
"watch" : {
|
|
"trigger" : { "schedule" : { "interval" : "10s" } },
|
|
"input" : {
|
|
"search" : {
|
|
"request" : {
|
|
"indices" : [ "logs" ],
|
|
"body" : {
|
|
"query" : {
|
|
"match" : { "message": "error" }
|
|
}
|
|
}
|
|
}
|
|
}
|
|
},
|
|
"condition" : {
|
|
"compare" : { "ctx.payload.hits.total" : { "gt" : 0 }}
|
|
},
|
|
"actions" : {
|
|
"log_error" : {
|
|
"logging" : {
|
|
"text" : "Found {{ctx.payload.hits.total}} errors in the logs"
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
|
|
All other settings for this API still apply when inlining a watch. In the
|
|
following snippet, while the inline watch defines a `compare` condition,
|
|
during the execution this condition will be ignored:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST _xpack/watcher/watch/_execute
|
|
{
|
|
"ignore_condition" : true,
|
|
"watch" : {
|
|
"trigger" : { "schedule" : { "interval" : "10s" } },
|
|
"input" : {
|
|
"search" : {
|
|
"request" : {
|
|
"indices" : [ "logs" ],
|
|
"body" : {
|
|
"query" : {
|
|
"match" : { "message": "error" }
|
|
}
|
|
}
|
|
}
|
|
}
|
|
},
|
|
"condition" : {
|
|
"compare" : { "ctx.payload.hits.total" : { "gt" : 0 }}
|
|
},
|
|
"actions" : {

"log_error" : {
|
|
"logging" : {

|
