UNIX way/KISS monitoring and alerting

What do you use to monitor multiple machines/servers/services/etc? I am interested in the most simple, flexible, and robust approach to monitoring/alerting. What kind of software, approaches, etc.

Systems like Nagios/Icinga and Zabbix seem to me very overloaded and are one big point of failure.

I know about Monit, Munin, RRDTools. But are there any even simplest options? It is possible even without external dependencies, i.e. databases, or even without additional software. Pure Bash? :)

What did you personally have to work with? What wheels did you invent? What turned out to be not so bad from experience, but what became bloated after a while?

Show some graphs, that's enough for me.

my friend uses monit

— monit

not only for local processes, but also to monitor different servers.
