How TipMe does Monitoring
● I know about 90% of site error without user report
● With only 3 alarms that has low false positive
● This is critical, as you want your user to be happy and
your day job boss to be happy

3 Alarms?
● Two alarms are Stackdriver Monitoring HTTP check
● One point to a generic user page
● One point to a health check page
○ Test database writing
○ Test cache server
○ Test job system
○ Test cloud storage writing
● The last one is error reporter
