I've looked at a bunch (Zabbix, Cacti, Nagios, BigSister, BigBrother, MRTG,
Cricket, Orca (Solaris only))and they all have different strengths.

Nagios is great for alerts when a threshold it reached, but logging isn't so
good.

We're using Zabbix where I am  now, but another admin sets the thresholds
and won't change them.  I've gotten good with email filters :-(  I get
alerts that NIS maps got changed twice a day but the timestamps haven't
changed for weeks.  If I could set my own,I'd probably like it alot.

Personally, I'd take a well tuned Nagios for alerts and something else for
tracking historical data on graphs.
I use swatch with multitail to watch logfiles on multiple systems.

Exposing the historical graphs to users is a good thing: they can see the
effect of doubling the number of developers on a system.
