Under AWS management console, launch instance and status checks shows 2/2 checks passed.

If status checks shows status 2/2 checked passed, then the instance is in healthy state.

AWS EC2 provides status checks that detect the problems with the underlying EC2 system used by the individual system. There are two types of checks performed every five minutes, which return a pass or a fail status. The two checks are:

System Reachability Check, which confirms that AWS is able to get the network packets to the user’s instance.
Instance Status Check, which detects a problem within the EC2 instance.
If both the checks are passed, the overall status of the instance will be OK. If one of the checks fails, the overall status of the instance will be impaired. The following guide demonstrates how to set the status check alerts for the instance.

The sample probable reasons for the failure of status checks include:

A) System connectivity Checks:

Loss of network connectivity
Loss of system power
Software issues on the physical host
Hardware issues on the physical host

B) Instance Status Checks:

Mis-configured networking or startup configuration
Exhausted memory
Corrupted file system
Incompatible kernel
