The command shows the follwoing for each worker:

|
|
* Process in which the worker is running

|
|
* ID of the task worker is processing
|
||
|
|
* Type of the task worker is processing

|
* Payload of the task worker is processing
|
||
|
|
* Queue that the task was pulled from.
|

|
|
* Time the worker started processing the task`,
