Parameters

Query Parameters

Name Description

logId Filter by historic external task log id.

externalTaskId Filter by external task id.

topicName Filter by an external task topic.

workerId Filter by the id of the worker that the task was most recently locked by.

errorMessage Filter by external task exception message.

activityIdIn Only include historic external task logs which belong to one of the passed activity ids.

activityInstanceIdIn Only include historic external task logs which belong to one of the passed activity instance ids.

executionIdIn Only include historic external task logs which belong to one of the passed execution ids.

processInstanceId Filter by process instance id.

processDefinitionId Filter by process definition id.

processDefinitionKey Filter by process definition key.

tenantIdIn Only include historic external task log entries which belong to one of the passed and comma-separated tenant ids.

priorityLowerThanOrEquals Only include logs for which the associated external task had a priority lower than or equal to the given value. Value must be a valid long value.

priorityHigherThanOrEquals Only include logs for which the associated external task had a priority higher than or equal to the given value. Value must be a valid long value.

deletionLog Only include deletion logs. Value may only be true, as false is the default behavior.

sorting

A JSON array of criteria to sort the result by. Each element of the array is a JSON object that specifies one ordering. The position in the array identifies the rank of an ordering, i.e., whether it is primary, secondary, etc. The ordering objects have the following properties:

Name	Description
sortBy	Mandatory. Sort the results by a given criterion. Valid values are `timestamp`, `taskId`, `topicName`, `workerId`, `retries`, `priority`, `activityId`, `activityInstanceId`, `executionId`, `processInstanceId`, `processDefinitionId`, `processDefinitionKey` and `tenantId`.
sortOrder	Mandatory. Sort the results in a given order. Values may be `asc` for ascending order or `desc` for descending order.

Result

A JSON array of historic external task log objects. Each historic external task log object has the following properties:

Name	Value	Description

externalTaskId	String	The id of the external task.
timestamp	String	The time when the log entry has been written.
topicName	String	The topic name of the associated external task.

errorMessage	String	The message of the error that occurred by executing the associated external task.
activityId	String	The id of the activity on which the associated external task was created.
activityInstanceId	String	The id of the activity instance on which the associated external task was created.
executionId	String	The execution id on which the associated external task was created.
processInstanceId	String	The id of the process instance on which the associated external task was created.
processDefinitionId	String	The id of the process definition which the associated external task belongs to.
processDefinitionKey	String	The key of the process definition which the associated external task belongs to.
tenantId	String	The id of the tenant that this historic external task log entry belongs to.
creationLog	boolean	A flag indicating whether this log represents the creation of the associated external task.
failureLog	boolean	A flag indicating whether this log represents the failed execution of the associated external task.
successLog	boolean	A flag indicating whether this log represents the successful execution of the associated external task.
deletionLog	boolean	A flag indicating whether this log represents the deletion of the associated external task.
removalTime	String	The time after which this log should be removed by the History Cleanup job. Default format* `yyyy-MM-dd'T'HH:mm:ss.SSSZ`.
rootProcessInstanceId	String	The process instance id of the root process instance that initiated the process containing this log.
