Which command do you use to show active alarms?

`show hardware state` provides general hardware status but does not specifically list active alarms.

The `show system alarms` command is the specific Junos OS command used to display active system and chassis alarms, including their severity and description. This command provides real-time information about critical conditions affecting the device.

`show chassis state` displays the operational state of the chassis components, not a list of active alarms.

`show services alarms` is not a standard or correct Junos OS command for displaying general system alarms.
