Each line of the log consists of common information available on any line of the tracelog, followed by event-specific information. The beginning of each line of the IP events log is exactly the same as those of any line on the tracelog. The generic information is distinct from the failure-specific information in that it is separated by colons (:) as in the following example:
20030227:000411863:46766:MAP(11111):MED:
Interpret the information as follows:
20030227 is the date (February 27, 2003)
000411863 is the time (00 hours, 04 minutes, 11 seconds, 863 milliseconds (ms) or 00:04:11 AM).
46766 is the sequence number of this entry.
MAP(11111) is the name and number of the process generating the event.
MED is the priority level (medium).
Following the generic information, the system displays the following information in brackets [] for all trace-route commands, whether successful or not:
Source board location
Source IP address
Network region
Destination IP address
-
Successful hops: information about successful hops along the route:
-
Unsuccessful hops: information about unsuccessful hops along the route:
Hop number
IP address of hop
Times – indicates “*” to indicate a failed hop or very large time periods
Error code indicating reason for failed hop (same as that returned from a user-initiated trace-route command)
Additional information specific to aborts of the trace-route
Tag indicating that automatic trace-route has been aborted and a reason
Note:
Even though some of the examples below show wrapped lines of text, both the Web page and the Linux log display one line for each entry.
