DESCRIPTION

Jstat reports the state of various Jaquith information. 
 

The status of all the physical devices can be obtained with the -devices option. The status of the jukebox’s client queue can be obtained with -queues. A list of the logical archives known to Jaquith can be obtained with -archlist.  At least one of the options must be given. 
 

For the -devices and -queues options, a jukebox manager must be specified. Strangely enough this is done by giving the name of a logical archive, not the name of a jukebox manager.  Jaquith will look up the jmgr for the given archive and contact it for the device or queue information. 
 

For each device being controlled by the jukebox manager the following is listed:

device-name current-volume current-owner
 

The status of the client queue can be obtained with the -queues option. The following is given for each waiter:
 

requestor-name desired-volume
 

BUGS

The queue information is for devices only; Clients which are waiting for write access to a logical archive (and therefore don’t yet know what device they need) are not reported.
