[hobbit] Re: [Hobbitmon-developer] Xymon client design (was Xymon is practically dead)

[Neil Franken]

Hi Henrik 

Agreed. However I have done some experimenting with a package called JCrontab. It is a scheduler and what I do is schedule VBS scripts and other exe to run via this scheduler. The scheduler runs the scripts/program and reads from the standard io . Since all my scripts/exe write to the standard io I can return OS specific information to the Java application which in turn open a socket and writes to Xymon. It is very simple and extensible. Anyway just a thought. The more ideas we have to discuss the better.

Regards
Neil

One very simple reason: The client needs to know about the
specifics of the operating system it is running on - that's 
the whole purpose of having a client! Java tries very hard to
isolate the underlying OS from the apps running inside the
JVM, which runs counter to this.

In other words - when you want to report on metrics specific
to the OS, it doesn't really make sense to use an OS-agnostic
tool.

Another reason is that the client shouldn't require a lot of 
additional software besides what comes with the OS. And the
output from the OS-specific tools will be well known to the
admins who are going to use the data from Xymon.
