=== Get rollup jobs API

|
|
This API returns the configuration, stats and status of rollup jobs. The API can return the details for a single job,
|
|
or for all jobs.
|
|
|
|
Note: This API only returns active (both `STARTED` and `STOPPED`) jobs. If a job was created, ran for a while then deleted,
|
|
this API will not return any details about that job.
|
|
|
|
For details about a historical job, the <<rollup-get-rollup-caps,Rollup Capabilities API>> may be more useful
|
|
|
|
==== Request
|
|
|
|
`GET _rollup/job/<job_id>`
|
|
|
|
//===== Description
|
|
|
|
==== Path Parameters
|
|
|
|
`job_id`::
|
|
(string) Identifier for the job to retrieve. If omitted (or `_all` is used) all jobs will be returned
|
|
|
|
|
|
==== Request Body
|
|
|
|
There is no request body for the Get Jobs API.
|
|
|
|
==== Authorization
|
|
|
|
You must have `monitor`, `monitor_rollup`, `manage` or `manage_rollup` cluster privileges to use this API.
|
|
For more information, see
|
|
{xpack-ref}/security-privileges.html[Security Privileges].
|
|
|
|
==== Examples
|
|
|
|
If we have already created a rollup job named `sensor`, the details about the job can be retrieved with:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET _rollup/job/sensor
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:sensor_rollup_job]
|
|
|
|
Which will yield the following response:

// TESTRESPONSE
|
|
|
|
The `jobs` array contains a single job (`id: sensor`) since we requested a single job in the endpoint's URL. The
|
|
details for this job contain three top-level parameters: `config`, `status` and `stats`
|
|
|
|
`config` holds the rollup job's configuration, which is identical to the configuration that was supplied when creating
|
|
the job via the <<rollup-put-job,Create Job API>>.
|
|
|
|
The `status` object holds the current status of the rollup job's indexer. The possible values and their meanings are:
|
|
|
|
- `stopped` means the indexer is paused and will not process data, even if it's cron interval triggers
|
|
- `started` means the indexer is running, but not actively indexing data. When the cron interval triggers, the job's
|
|
indexer will begin to process data
|
|
- `indexing` means the indexer is actively processing data and creating new rollup documents. When in this state, any
|
|
subsequent cron interval triggers will be ignored because the job is already active with the prior trigger
|
|
- `abort` a transient state, which is usually not witnessed by the user. The `abort` state is used if the task needs to
|
|
be shut down for some reason (job has been deleted, an unrecoverable error has been encountered, etc). Shortly after
|
|
the `abort` state is set, the job will remove itself from the cluster
|
|
|
|
Finally, the `stats` object provides transient statistics about the rollup job, such as how many documents have been
|
|
processed and how many rollup summary docs have been indexed. These stats are not persisted, so if a node is restarted
|
|
these stats will be reset.
|
|
|
|
If we add another job, we can see how multi-job responses are handled:
