binary format. The binary run-time log files reside in the
< install_path> is where you installed the Couchbase
You cannot open these binary files directly. To dump the run-time logs into a text file, run the browse_logs.bat file, located <install_path>\bin\browse_logs.bat. This command dumps the logs to standard output in a human-readable text format. You can redirect the output of this batch file to a text file that you can save for later viewing or email to Couchbase Technical Support. The following example redirects output to a text file named nslogs.txt.
