Couchbase Server stores its logs in an efficient, space-limited binary format. The binary run-time log files reside in the following path<install_path>\log (where < install_path> is where you installed the Couchbase software).

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.

shell> "C:\Program Files\Couchbase\Memcached Server\bin\browse_logs.bat" > C:\nslogs.txt
