Alternative to DebugView

[Eric Lendvai]

I use Windows DebugView all the time to monitor errors and help debug services and libraries. DebugView is a great solution when an issue is not critical, but a developer should be made aware of, or when some QA staff can help you trace down issues in a program.

But DebugView is only for Windows.

On Linux system I had to write to log files. But that will slow down execution and you have to deal with cleaning up those log files.

Does anyone have another solution for under Linux? Maybe some sort of socket based communication and a local client that behaves like DebugView?

In linux we should use the syslog...

I don't remember if it is already supported...

Yes it is. The good stuff with syslog is that if you use rsyslog you can forward the log to a central server. I'd like to implement sending messages to a remote syslog server from windows...

Anyway, from harbour sources
