We just finished log collecting and viewing system. Log analizing problem was very actual, because we have not one server servers — game, resource, generator. During test stage we’ll have to handle clients messages too.

Architecture

Logging server is based on OSGI platform. We recieve logs via RMI using JAAS authorization (we had to write an appender for Log4j). Logs are saved with Hibernate into PostgreSQL database. And we wrote some plug-ins for Eclipse for viewing too. Basic features — log filtering with different criterias and filter save function.

There are still 8 steps to testing… :-)
