Couchbase Server stores its logs different places, depending on the component reporting the error. The core memory and replication logs are stored in an efficient, space-limited binary format under /opt/couchbase/var/lig/couchbase/logs. A Couchbase shell script (cbbrowse_logs) will output these logs in a human-readable text format.

To dump the most recent 100MB of logs as text, run the following command:

shell> cbbrowse_logs

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> cbbrowse_logs > /tmp/nslogs.txt
