TOPS VSN Log and alarm messages
Header Information For TOPS VSN Log Messages.Identifying information, also known as header information, uniquely identifies
each log and alarm message. The header of every log or alarm message
generated by TOPS VSN contains the following:
(a) Date and Time. The date and time are displayed in the upper left of the
message. The format of the date is yymmdd, and the format of the time is
hh:mm.
(b) Severity. Each log message specifies the severity of the event it is
reporting. The following terms or values are used to indicate severity:
*C Critical Severity 1 Logs with this severity generate critical
alarms. These logs and alarms are the result
of catastrophic failures such as power
failures.
** Major Severity 2 Logs with this severity generate major
alarms. These logs and alarms are the result
serious failures such as PRUs being unable
to initialize.
* Minor Severity 3 Logs with this severity generate minor
alarms. These alarms are used to flag
problems that need either a visual or
audible display at the TOPS VSN site. An
example of a problem that would cause a
minor alarm is an incorrect table entry.

Severity 4
Severity 5
Severity 6
Severity 7
These are intermediate severity ratings. An
event is a happening that does not effect
service. The event is simply logged for the
record. An error is also considered non-
service affecting. It is an isolated error
condition caused by the system, for
example, a single lost call.
Warning/
Trouble Severity 8 This log severity indicates a warning.
Status Severity 9 This log severity reports the status of a
particular software or hardware unit. The
percentage of disk space used is an
example of a log with status severity.
Progress Severity 10 Log reports the progress of an event.
Severity 11-13 These severity ratings are not defined for
TOPS VSN.
