An Amazon Web Services adapter fails to collect and display metrics.
The Amazon Web Services instance log contains this message.
AWS Error Message: Request timestamp is too skewed. Timestamps must be within 900 seconds of server time.
The time on the vRealize Operations Manager system is set to the wrong time and out of synchronization with the Amazon server. On the Amazon side, the time the request comes in is compared to the time the request was made. The time the request was made is based on the local client system time. If the times are too far apart, the Amazon server rejects the request.
Update the time on the vRealize Operations Manager system to the correct, current time.
