The PHPLogCon SyslogAppliance is a ready to run logging system which can be deployed right "out of the box". Just plug it into any VMWare environment and enjoy receiving log messages from a variety of sources, including Routers, Firewalls and even Windows event logs. It is a great troubleshooting, reporting, analysis and capacity planning tool.
SyslogAppliance 0.0.6 has been released on January, 26th. It offers a new automatic database cleanup option and includes the most recent version (2.5.23) of phpLogcon. Also, an upgrade of the base operating system has been done. The version is still based on a uniprocessor kernel. A multiprocessor version is in the works.
SyslogAppliance works on top of the widely known VMWare virtualization solutions. All important VMWare versions are supported, including the free VMWare player, VMWare ESX server and other VMWare server products.
