Chapter 13 Alarm Monitoring and Management
13.4 Viewing Alarms
Table 13-2 lists the color codes for alarm and condition severities. The inherited (I) and unset (U)
severities are only listed in the network view Provisioning > Alarm Profiles tab. They are not currently
implemented.
Note Major and Minor alarms may appear yellow in CTC under certain circumstances. This is not due to a
CTC problem but to a workstation memory and color utilization problem. For example, a workstation
might run out of colors if many color-intensive applications are running. When using Netscape, you can
limit the number of colors used by launching it from the command line with either the -install option or
the -ncols 32 option.
In network view, CTC identifies STM and VC alarm objects based upon the object IDs. Table 13-3 lists
the object numbering schemes for the MON (such as HPMon and LPMon) and TERM (such as HPTerm
and LPTerm) objects.
Num Num (number) is the quantity of alarm messages received, and is incremented
automatically as alarms occur to display the current total of received error messages.
Ref Ref (reference) is a unique identification number assigned to each alarm to reference a
specific alarm message that is displayed.
