Get Activity Instance Statistics

Retrieves runtime statistics of a given process definition, grouped by activities. These statistics include the number of running activity instances, optionally the number of failed jobs and also optionally the number of incidents either grouped by incident types or for a specific incident type.
Note: This does not include historic data.

Method

GET /process-definition/{id}/statistics

GET /process-definition/key/{key}/statistics (returns statistics for the latest version of the process definition which belongs to no tenant)

GET /process-definition/key/{key}/tenant-id/{tenant-id}/statistics (returns statistics for the latest version of process definition for tenant)

Parameters

Path Parameters

Name Description
id The id of the process definition.
key The key of the process definition (the latest version thereof) to be retrieved.
tenant-id The id of the tenant the process definition belongs to.

Query Parameters

Name Description
failedJobs Whether to include the number of failed jobs in the result or not. Valid values are true or false.
incidents Valid values for this property are true or false. If this property has been set to true the result will include the corresponding number of incidents for each occurred incident type. If it is set to false, the incidents will not be included in the result.
incidentsForType If this property has been set with any incident type (i.e., a String value) the result will only include the number of incidents for the assigned incident type. See the User Guide for a list of incident types.

Note: The query parameters incidents and incidentsForType are exclusive. It is not possible to send a request with both query parameters. In that case the response will be a bad request.

Result

A JSON array containing statistics results per activity. Each object has the following properties:

Name Type Description
id String The id of the activity the results are aggregated for.
instances Number The total number of running instances of this activity.
failedJobs Number The total number of failed jobs for the running instances.
Note: Will be 0 (not null), if failed jobs were excluded.
incidents Array Each item in the resulting array is an object which contains the following properties:
  • incidentType: The type of the incident the number of incidents is aggregated for. See the User Guide for a list of incident types.
  • incidentCount: The total number of incidents for the corresponding incident type.
Note: Will be an empty array, if incidents or incidentsForType were excluded. Furthermore, the array will be also empty if no incidents were found.

Response Codes

Code Media type Description
200 application/json Request successful.
400 application/json If both query parameters incidents and incidentsForType were set. See the Introduction for the error response format.
404 application/json Process definition with given key does not exist. See the Introduction for the error response format.
