Viewing the service log
Service logs are logs written in a binary format. You cannot view
a service log directly using a text editor. You should never directly edit
the service log, as doing so will corrupt the log.
To
move a service log from one machine to another, use a mechanism like
FTP, which supports binary file transfer. You can view a service log in two
ways:
- It is recommended that you use the Log and Trace Analyzer tool to view
the service log. This tool provides interactive viewing and analysis capability
that is helpful in identifying problems.
- If you are unable to use the Log and Trace Analyzer tool, use the Showlog
tool to convert the contents of the service log to a text format that you
can then write to a file or dump to the command shell window.
