Hello,
I am using eventbride to issue EC2 RebootInstances API Call to a number of machines.
Most shutdown and boot well. 1 does not seem to receive the shutdown request and does a dirty restart.
I can see that successful machines have an event 109: 'The kernel power manager has initiated a shutdown transition. Shutdown Reason: Kernel API' .
The failed machine does not.
Checking the SSM logs on a good and bad machine, the log before the reboot looks identical other than time stamps. These two comparison machines are same ssm agent version, same windows, instance type.
Cloudtrail / eventbridge logs don't show failures.
Can anybody give me a pointer where to look for this issue?
thank you
