2) I'm a fan of argus for system + network monitoring. it's
manufactured locally!
argus.tcp4me.com
1) some balance between
a) just basic critical services
smtp on the mail server, http on the web server, ...
b) everything that can be monitored
ping times, cpu load, disk usage, disk activity, zfs status,
dns authoritativeness, web page content, interface errors, ...
where to set alerting threshholds depends mostly on
a) your tolerance for suckiness
b) your lead times for repairing, replacing, or upgrading
3) yes. network utilization, ping times, interface errors, BGP peer
status, ...
