Queue
Function: Warm start ZMON
Format: zmon queue
If ZMON terminates or is killed (although unusual), it may be restarted
using the QUEUE command. Since all of the ZCOM context data is kept
in the ZCOM kernel tables, ZMON can be restarted at any time with this
command.
ZMON usually waits for events on the /dev/zmon device file queue.
During normal operation no events are posted to this queue, however, if
for example, a Mux fails for some reason, a failure event is added to the
queue by the LDM, and ZMON is awoken. ZMON will then read the
event from the queue and take the appropriate action.
