NetScaler SD-WAN Standard Edition in AWS now supports basic CloudWatch for monitoring your SD-WAN instance running on AWS infrastructure. CloudWatch alarms send notifications or automatically make changes to the resources you are monitoring. Under basic monitoring, seven pre-selected metrics at five minute frequency and three status check metrics at one minute frequency are available for your SD-WAN instance for no additional charge. You can view the following metrics for your SD-WAN image.

b) Diskread operations - Read operations from all instance volumes available for the specified period.
c) DiskWrite operations – Write operations for all instance store volume available for the instance in a specified duration of time.
d) DiskReadBytes – Bytes written to all instance store volumes available to the running instance
e) NetworkIn – This metric identifies the volume of incoming traffic for a single instance.
f) Network Out - This metric identifies the volume of outgoing traffic for a single instance.
g) Networkpacketsout – Number of packets sent out on all network interfaces by the instance, this is only available for basic monitoring.
