Logging

the custom couch_log module in Apache Couchdb has been replaced by lager version 2.0, a widely used logging application written by Basho.

You can setup the logging in the app.config file. For more informations about its config have a look in the lager README.

In rcouch you can also filter logs by task.

To get all replications logs add this line to your configuration file:

{lager,
  [{crash_log, "log/crash.log"},
   {error_logger_hwm, 100},
   {handlers,
    ..
     {lager_file_backend, [{file, "log/replication.log"}, {level, none},
                           {size, 10485760}, {date, "$D0"}, {count, 5}]}
    ]},
   {traces, [
    { {lager_file_backend, "log/replication.log"}, [{task, replication}], debug},
    { {lager_file_backend, "log/replication.log"}, [{task, replication}], info},
    { {lager_file_backend, "log/replication.log"}, [{task, replication}], error}
   ]}
  ]},

For now only the replication task can be logged completly. views indexation and couchapp engine logs (javascript traceback) will be added soon.
