Monitoring system for ec2 linux instances

Question

Amazon Web Services

We need a monitoring system (and, preferably, notifications), like zabbix, which can automatically add servers for monitoring:
the auto-scale feature of Amazon ec2 is used, because new servers appear themselves from the same ami. It is necessary that new servers be centrally monitored until they are destroyed, which happens automatically.

What systems with such capabilities can you recommend?

Answer 1
