How to setup multiple alerts on single graf

Question

I want to create several alerts for logins to application. Its typical that users have login patterns:

• 00-06 01-02 users/min, more then 5 is some kind of problem
• 06-16 30-60 users/min, above 120 is some kind of a problem
• 16-24 05-10 users/min, more then 20 is some kind of problem.

Is this possible to achieve on single graf by providing multiple alerts each working in specific time range ?

Answer 1

One simple way to do this is to write a synthetic series with your threshold, then alert when the delta between the actual count and the "threshold" series is greater than 0.
