The primary source for run-time logging information is the Couchbase Server Web Console. Run-time logs are automatically set up and started during the installation process. However, the Couchbase Server gives you access to lower-level logging details if needed for diagnostic and troubleshooting purposes. Log files are stored in a binary format in the logs directory under the Couchbase installation directory. You must use browse_logs to extract the log contents from the binary format to a text file.
