Taken one at a time, mos of them are simple.  Most of life is like that.

I've actually been out of the admin biz for some time but back in the 
day I was very found of SNMP tools for all sorts of reporting.

For output I liked MRTG for most things, WhatsUpGold had some nice 
features if you would rather pay money.

For alarms, I used some unix hack or another (home-made).

I also used home-made hacks to gather data about things that did not 
have a suitable SNMP interface.

See MRTG, RRD, et al.

I had the luxury of management that thought managing was a good idea, so 
I had a machine pretty much dedicated to systems management and all the 
machines (including routers, bridges, hubs, and such) reported to it. 
We had a web interface to the MRTG and MRTG-like presentations.

Just before the fired me for being too old, they bought all the HP and 
cisco stuff in the world.  I do not recommend any of it.
