Tracing and Logging
Tracing and Logging
HP SNMP/XL uses the NMS utility NMDUMP for tracing and logging.
HP SNMP/XL also follows the general format of NetXport, NetIPC, and
NS services in tracing and logging. This includes initiation and
formatting options.
Tracing
A trace initiation is able to trace the subsystem startup and allows you
to specify the trace file name and file size. There is a single command
for turning on/off tracing which is SNMPCONTROL TRACE.
The following filters are available for formatting the trace file:
• Time range selection.
• Subsystem ID.
• Data display options (octal, hex decimal, ASCII).
• Exception reporting.
System Logging
The logging destination for messages with various logging classes is
provided through NMMGR guided configuration. The general message
format looks like:
Message text (SNMPFATAL nnnn)
(SNMPINFO nnnn)
(SNMPWARN nnnn)
(SNMP nnnn)
where nnnn is the message number.
Message Content
The following information is included in the message record to allow for
formatting options based on these criteria:
• Subsystem ID.
• Logging class.
• System time stamp.
• Log all SNMPCONTROL commands issued.
