Analyzing cluster log files using Logsurfer
James E. Prewett · 2003
Logsurfer is a log file analysis tool that simplifies cluster maintenance by aiding in the identification and resolution of problems. Logsurfer examines messages in a log file in terms of how they relate to other messages. Logsurfer is also capable of modifying its ruleset at run–time. These capabilities allow Logsurfer to detect complex patterns in log files and act based on what it finds. Large clusters require this sort of log file analysis to enable the system administrators to efficiently do their job. Complex interactions within the cluster are common. Logsurfer puts the pertinent information right at the administrator’s fingertips when she needs it to analyze the problem. Acting on this information on behalf of the administrators frees them up to work on more important issues. This paper examines the uses of Logsurfer in a cluster environment. The reader of this article should be able to configure Logsurfer to meet the needs of their particular environment.
