[LRUG] How do you monitor your web site?

We have several tools in place for monitoring our sites. The stack we 
usually configure is:

     - Check if site is alive and in good shape: Pingdom [1]. You can 
configure easy checks like looking for presence/lack of some literal
     - Exception notifications: We use the exception notifier [2] 
plugin. Combined with an ugly-but-functional plugin [3] by yours truly 
you can get alerts both by e-mail and twitter when things go wrong. In 
some projects we have tried hoptoad [4]. Pretty good but you have to pay 
for it. The free alternative is good enough for us.
     - Monitor system processes and restart unresponsive ones: Monit [5]
     - Performance issues (identify bottlenecks, check trends): New 
Relic [6]
     - Visitor's behaviour/metrics: Google Analytics [7]
     - Obscure network monitoring: I know we are using nagios[8] for 
that, just not sure about what for exactly ;)
     - Database performance: mysql slow query reports [9]
