Hi @abel_zhyb,

Next time, it’s probably better to break up these unrelated questions.

  1. What do you want to resolve? I believe you can change the directory when you first install Couchbase, but it sounds like you’re running out of disk space.

  2. I don’t think there’s any way to monitor client activity from the the web console, other than queries that currently being executed. You can turn on more detailed logging from the Java client.

  3. To get the key, use META().id. For example, “SELECT META(t).id FROM `travel-sample` t LIMIT 10”;
