In the following definitions of the different fields, there are references to
$PORT, $FIRQ and $STDT, transactions. For more information on these
transactions, refer to the backplane protocol descriptions.
ISTIME - Time of last ZMON restart/shutdown this card.
This field contains the time (seconds since the Epoch) when ZMON last
processed a restart or shutdown request for this card. It is used
internally by ZMON to detect and ignore multiple restart/shutdown
requests.
BC1_ADDR - First level bus converter address for this MUX interface
card
For HP9000 Series K systems the address is of the form bc1/bc/s. This
field refers to the first level bus converter address indicated as bc1. For
other systems this field is initialized to zero.
BC_ADDR - Bus converter address for this MUX interface card
This field contains the I/O bus converter address representing the I/O
bus that the MUX interface card is installed in. On systems that contain
only one I/O bus (S8x7, I30, H50, etc.), this field is initialized to zero.
