Are you kidding?

Unix monitoring tools are far more advanced and powerful than anything available for Windows. It's just that your Windows-centered requirements are not met since Unix apps won't be written to exactly copy what you see in Windows.

Where I work now we have over 4000 Unix servers. All of them are monitored at all times and we have set up alerting to send emails, pages, or both when certain criteria are reached. We can customize the criteria based on which categories a server belongs to. For example, the same error might cause a production server to send a page, but a development box to just send email. We can control who gets the notifications the same way so each group of admins and users gets alerted for only the servers they care about. We can generate reports per server or per group of servers containing all the data you mentioned plus lots more. I would certainly consider that a "high degree" of monitoring.

As System Shock mentioned, Unix has the commands built in to do exactly what you want, if you drop the extreme restrictions. If you really need to buy a commercial product you could look at Nagios with purchased support, Tivoli, HP Openview, several products from Computer Associates, Sysedge from Concord Software, Splunk, or many other SNMP based monitoring products. All of them have sophisticated reporting features and a gui dashboard, but they won't be exactly the same as your windows monitoring apps of course.

The bottom line is if you want powerful, customizable Unix monitoring that can give you exactly the information you want you have many choices that can do it. If you expect it to also spoon-feed you reports in the specific canned format of your choice or show you a gui exactly like your windows boxes have you may be out of luck.
