In general, the invention facilitates diagnosing fault conditions, such as
flapping, by permitting users to request information for specific
components in a network device such as a router. The invention also
facilitates the diagnosis of other fault conditions, including, but not
limited to, excessive numbers of dropped packets, hard drive crashes,
high temperature readings, and inactive interface cards. A user may
obtain a targeted log containing information relating to selected fault
conditions or other network device events, rather than a system log
containing information relating to all network device events, some of
which may not be of interest to the user. The targeted log may be parsed
and analyzed with greater ease than the system log.
