Log monitoring for membase 1.7

I need to monitor membase log messages. I have found two ways to do that:

1) Via JSON request to http://membase_server:8091/logs
2) mbbrowse_logs

First method shows logs from whole membase cluster rather quickly, but I need to parse JSON output. Second method analyses binary logs from local membase server only and it tooks some time to read all binary logs file.

Is there a tool for membase which could show whole cluster log in simple syslog format? At the moment the more suitable method for me is to write utility which will parse JSON output and write logs to simple file.

Maybe I missed something?
