Section 6 Status Displays
Device Identification
The first line of the Diagnostic Message Display provides the device/subdevice
number, type, and state of the device.
Archive Messages
The total number of records stored in the disk archive file is shown as a percentage
of the total size of the archive in the MESSAGE mode, or as an exact number of
messages in the ARCHIVE mode. Regardless of the mode, the number of records is
shown in yellow if the file is 75 to 90 percent full and red if over 90 percent full.
This serves to indicate when the oldest messages in the archive are in danger of
being lost. This occurs because the archive has a fixed size, and if it is full (2999
messages) the oldest message is erased to make room for a new message. It is not
necessary to do anything about this condition unless there have been problems
which require future examination of messages that are now in the archive.

DESCRIPTION Shows the message text and severity. The first time a message
occurs, it is archived with a frequency count of 1 and saved in local memory. Each
time the same message occurs again, the frequency count increments in the local
copy. On the display, indication that a message is being counted in local memory is
shown by a greater than sign (>) in the first column. Ten minutes after the first
occurrence, or when flushed from local memory to make room for newer messages,
the message is archived with its final time and count (if more than one) and removed
from local memory. If the same message occurs again, the process starts over. The
severity of each message is indicated by the letter to its right and by a color as
follows (default colors indicated):
