zLogFabric is an all in one cross-platform logging solution that collects log lines/messages over a messaging system to a central server instance. The modular design enables the server to store, forward, alert, and generate live statistics out of the logged data. It can collect log information from files, syslog, log4j, log4net, and Windows event logs.
springclean is a command line tool for cleaning up log files. It can select files based on name (exact or regex), age, or a combination of both. You can preview changes, and confirm before running each action. For each action you can find how much disk space has been freed, compress, move to another directory or remove your files, and create an audit trail with syslog.
