I need some monitoring tools for SCO 7.1.4
Does anybody reccomend some software that I can install to monitor mem leaks and odd SAR values etc
I don't know weather following tools saffice your needs
1> monit Easy, proactive monitoring of processes, programs, files, directories, filesystems and hosts | Monit
2> nagios http://www.nagios.org/
Try ZABBIX (www.zabbix.com)
You can graph memory utilisation, and it's *heavily* customisable. And free 
We use it across our entire Production network of Solaris, Linux, SCO and VMWare ESX boxes.
Cheers
