Informix DB Tools Information needed

Hi, Is anyone aware of some good Informix DBA tools for helping to administer the technical database view. The things I want this tool to do is to check extents, and reorganise the table. Some other things it might do is to track errors and limits. Let's just say I need a somewhat advanced version of onmonitor. If you use some tools or are aware of the existance of some please let me know, I searched the net a while and I haven't found anything usefull. Thanks in advance, Rob Prop, Database Consultant Informa Automatisering bv The Netherlands P.S. I know we can build this tools ourselves, but why should we if it already exists.
