[[rollup-get-job-prereqs]]
|

==== {api-prereq-title}
|
|
|
|
* You must have `monitor`, `monitor_rollup`, `manage` or `manage_rollup` cluster
|
|
privileges to use this API. For more information, see

{stack-ov}/security-privileges.html[Security privileges].

[[rollup-get-job-desc]]
|
|
==== {api-description-title}
|
|
|
|
The API can return the details for a single {rollup-job} or for all {rollup-jobs}.
|
|
|
|
NOTE: This API returns only active (both `STARTED` and `STOPPED`) jobs. If a job
|
|
was created, ran for a while then deleted, this API does not return any details
|
|
about that job.
|
|
|
|
For details about a historical {rollup-job}, the
|
|
<<rollup-get-rollup-caps,rollup capabilities API>> may be more useful.
|
|
|
|
[[rollup-get-job-path-params]]
|
|
==== {api-path-parms-title}
|
|
|
|
`<job_id>`::
|
|
(Optional, string) Identifier for the {rollup-job}. If it is `_all` or omitted,
|
|
the API returns all {rollup-jobs}.
|
|
|
|
[[rollup-get-job-response-body]]
|
|
==== {api-response-body-title}
|
|
|
|
`jobs`::
|
|
(array) An array of {rollup-job} resources.
|
|
`config`:::
|
|
(object) Contains the configuration for the {rollup-job}. This information
|
|
is identical to the configuration that was supplied when creating the job
|
|
via the <<rollup-put-job,create job API>>.
|
|
`status`:::
|
|
(object) Contains the current status of the indexer for the {rollup-job}.
|
|
The possible values and their meanings are:
|
|
+
|
|
--
|
|
- `stopped` means the indexer is paused and will not process data, even if its
|
|
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` is a transient state, which is usually not witnessed by the user. It
|
|
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.
|
|
--
|
|
`stats`:::
|
|
(object) Contains 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. If a node is restarted, these
|
|
stats will be reset.

If we have already created a rollup job named `sensor`, the details about the
|
|
job can be retrieved with:
|
|
|
|
[source,console]
|
|
--------------------------------------------------
|
|
GET _rollup/job/sensor
|
|
--------------------------------------------------
|
|
// TEST[setup:sensor_rollup_job]
|
|

The API yields the following response:

The `jobs` array contains a single job (`id: sensor`) since we requested a single job in the endpoint's URL.
|
|
If we add another job, we can see how multi-job responses are handled:
|
|
|
|
[source,console]
|

|

GET _rollup/job/_all <2>

// TEST[setup:sensor_rollup_job]
|

<1> We create a second job with name `sensor2`
