nagios vs Hyperic - Not the same

Nat replied: "Deployment tools have never been open source's strong point: OS has always been about the developer, rarely about the deployer. cf the hacker's disdain for IT who get stuck with deployment and management. That said, there are some open source tools like nagios (for system monitoring) and capistrano (for rails deployment). The feedback loop there tends to be that the people writing the tools are the ones with the deployment problem. The downside is that if your need isn't met by the tool, it may be hard to get the developer to add it. (That's why Hyperic is on good terms with Nagios: the Nagios developer will never add the features that Hyperic has.)"
