Correlating and analyzing OMEGAMON log files with the Log Analyzer
The correlation function lets you bring together logs from multiple servers organized by timestamp for environment-wide analysis. Your OMEGAMON® log files can be combined in a single view, ordered by time stamp, to correlate the operation of the IBM® Tivoli® Management Services components.
When you are trying to correlate log files from multiple servers, the time clocks on those servers can be out-of-sync. This synchronization problem could be something simple, such as different time zones, or more subtle, such as a clock being a few milliseconds off from another server's clock. The Log Analyzer imbeds a function to synchronize the time between multiple log files by allowing you to adjust the time stamps in a log file. For more information, refer to the topic titled “Synchronizing time of log records for distributed applications” in the Log Analyzer online help.
There are two ways to correlate log files: simple correlation and advanced correlation.
