Is there a perfmon-like for Linux?

Answer 1

If you're looking for a way to monitor this stuff on servers, you should be looking at a monitoring framework like Zabbix. This will let you monitor all sorts of interesting things about your system and, with plugins, your application - as well as storing trend data for a period of time, and letting you alert on trigger thresholds and such.
