BOXI service monitoring

All,

I just wanted to get an idea from the experts here - which tool/application, in your experience, has done a good job in monitoring of Windows-based system services (BO XI R2 services to be specific)? I am looking for some open-source (or freeware) tool that can help me with monitoring for the status of all BO services, including Tomcat. Any alerting capabilities when services go down or are high on CPU/RAM utilization would be added bonus, but if not, basic service monitor would be okay as well.

Has anyone used any OTS or custom tools for this kind of systems administration on Windows-based BO servers?

Regards,

Sarang
