You can view the properties of each event log (in either the Logs to be Analyzed or Analyzed Logs nodes). The properties of an event log includes the size of the log, the date created, the date and times of the first and last events in the log, the number of events and users, and the computer where the event log was created.
In the Logs to be Analyzed or Analyzed Logs results pane, right-click the event log file whose properties you want to view and choose Properties from the shortcut menu. The Event Log File Properties dialog box appears.
