Xymon (nee Hobbit, a clone of BB) needs very little configuration for a basic 
environment, and provides lots of features Nagios didn't provide (last time I 
looked at Nagios):

1)Install xymon package on monitoring server and start xymon service
2)Install xymon-client on hosts to be monitored (for cpu,processes, disk 
utilisation, log file alerting etc.) and put IP of monitoring server in 
/etc/sysconfig/xymon-client, start xymon-client service
3)Add a default alerting rule

By default, you will have some relatively sane default thresholds, load 
average graph, memory/swap graph, disk utilisation graphs. Other default 
trends (not alerted on by default) include network statistics, vmstat graphs. 
Some checks supported without any additional installation require some 
configuration (log files, ports, processes).

Built-in network service monitoring is advanced in some cases (http, ldap), 
but not as advanced for others (e.g. default smtp check just checks for a 
header, no smtp auth).

There are probably fewer extensions than Nagios plugins though (and I need to 
finish some I have been working on).

If we want a more service-based approach (e.g. ITIL), then Zabbix may be 
better.

The Nagios interface always makes me feel lost ...
