Usage metrics

Tasklist provides usage metrics under usage-metrics Actuator endpoint. It is exposed on management port, which can be configured via management.server.port configuration parameter (default: 8080).

Number of active users

This endpoint returns the number of unique users assigned to tasks in a given period and each of the unique usernames.

This also returns the usernames so we can reconcile in the case of multiple instances.

Endpoint:

http://<host>:<port>/actuator/usage-metrics/assignees?startTime={startTime}&endTime={endTime}

Here, startTime and endTime are of format yyyy-MM-dd'T'HH:mm:ss.SSSZZ, e.g. "1970-11-14T10:50:26.963-0100".

Sample response:

{
    "total" : 2,
    "assignees": [
        "john.lennon", 
        "oprah.winfrey"
    ]
}
