Diagnosis of network fault conditions
First Claim
1. A method comprising:
- receiving, with a client device, a diagnose command that specifies a selection criteria using extensible markup language tags;
sending a request for information from the client device to a network device to retrieve a system log that contains information relating to a plurality of network device events for a plurality of different components of the network device;
generating, with the client device, an abridged system log from the system log by extracting information from the system log based on the selection criteria; and
presenting the abridged system log to a user with the client device.

Abstract
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.

12. A client machine comprising:
-
a physical interface for communicating with a network; a programmable processor configured for; presenting an interface supporting input by which a user initiates remote diagnostics of a network device, wherein the input includes at least one user-specified criterion, in response to the input, automatically formatting one or more commands using extensible markup language tags and sending the commands from the client machine to the network device to retrieve a system log that contains information relating to a plurality of network device events for a plurality of different components of the network device, and extracting the information from the system log and producing an abridged system log for presentment to the user. - View Dependent Claims (13)
