Alternate Collector Event Messages
The alternate collector generates event messages to describe occurrences in the
alternate collector environment. The collector writes all these messages to the primary
collector log file. It also writes most of the messages to the alternate collector log file.
These messages inform you of these kinds of events:

An alternate collector shutdown after a STOP command

The successful creation of a new collector process in the backup CPU
Summary of Collector-Generated Messages
In these tables listing collector events, the column labeled Critical identifies each
message as being critical (Y) or not critical (N). The EMPHASIS token in the message
header is set to TRUE if the event is critical, and to FALSE if the message is not
critical.
Messages 1 through 512 are shown with BEL? in the Critical column. The presence or
absence of a BEL character in the text of the message determines whether or not the
message is critical. A numbered console message or a text message sent with a
WRITE command can contain a BEL character in the text. If the BEL character is
present, the collector that generates the tokenized message sets the EMPHASIS token
to TRUE. If the BEL character is not present, the EMPHASIS token retains its default
value of FALSE.
For descriptions of the content of the operator console messages, see the Operator
Messages Manual.
