loggingprocesstopusers
I need to log all processes (including the amount of CPU usage used, the time it was running for, etc…) to a txt file; preferably one entry per line as it appears in top.
The user appears to be running an abusive process via cron however I want to monitor it and be sure of the usage it is actually using on the server so to be sure and also so I have proof (with timestamps preferably too).
Cheers,

You can set COLUMNS environment variable to a large value. For example, to set it just for top invocation:
$ COLUMNS=1000 top -c -b -n 1 > top.log
At least it works in bash 4.0.33 on Ubuntu 9.10.
To be honest, I would use Monit for this. It's available from RPMForge via yum for your particular version of Linux.
Monit is a tool for monitoring processes and daemons. Usually this is done via PID, but you can also match on a process string. Since VMWare Server process strings end in a "vm_name.vmx" specification, you can set Monit to check against that string. The only example of a VMWare Server 1.0.x system I have handy has ONE VM running, but as long as you know the names of the *.vmx files, you can list them independently in the monit config file.
Here's the output of monit procmatch vmx:
[root@abc ~]# monit procmatch vmx
List of processes matching pattern "vmx":
------------------------------------------
/usr/lib/vmware/bin/vmware-vmx -# product=2;name=VMware Server;version=2.0.1;buildnumber=156745;licensename=VMware GSX Server for Linux;licenseversion=3.0 build-156745; -@ pipe=/tmp/vmhsdaemon-0/vmx226abb1efa53200b;readyEvent=52 /vmware/abc_Web/abc_Web.vmx
------------------------------------------
Total matches: 1
Adding a small VMWare check entry to the monit config file (create and entry for each unique VM you need to monitor)...
check process vmware
matching "vmware-vmx"
This shows the status of what's being monitored.
[root@abc ~]# monit status

Try this:
top -b -d <interval-in-secs> -u <username> >> /tmp/top.log &This will write every $INTERVAL all processes run by the specified user to a logfile.
