Nutanix ecli task.list Command

If Nutanix progress_monitor_cli –fetchall command does not show any running / stuck / hung task list or does not kill the task. You do not worry Nutanix has another task management service known as Ergon task manager service.

Nutanix Ergon is the task manager that is responsible to start and kill the running , stuck tasks automatically and/or manually if needed. /
Ergon task manager has two versions of command first is ergon_update_task that is available to kill the task.

But Nutanix has evolved the second verson of ergon task manger with advance commands launched with AOS version 5.5 or later ecli ( Ergon Command Line Interface ) to manually show the running, stuck , hung task(s) list.

Nutanix acli task.list Command

Nutanix acli task.list command is obsoleted and no longer available in latest AOS 5.10 or later version.

Note: acli command is available but task.list command is removed in latest AOS versions.

In my personal opinion – acli task.list was not powerful as super expected, that might be the reason Nutanix removed this command from acli command interface.

Hopefully, you got the more clarity and detailed information how to kill the running , hung, stuck task(s) in Nutanix via progress_monitor_cli and ecli task.list command.
