Private IP address EC2 instance on-premises host report: mtr -n -c 200 MTR version 0.85 and later have the TCP option. The TCP-based results determine if there's application-based packet loss or latency on the connection. Confirm that the security group and network ACL rules allow traffic from the source on the protocol and port. Make sure that the test port is open on the destination instance.Make sure that the security group and network access control list (network ACL) rules allow ICMP traffic from the source instance.Because the path between nodes on a TCP/IP network can change when the direction is reversed, get MTR results from both directions.īefore you run the tests, check the following configurations: Run the following tests between the private and public IP address for your EC2 instances and on-premises host. Note: For Windows operating system (OS), WinMTR doesn't support TCP-based MTR. See the SourceForge website to install WinMTR. To check for ICMP or TCP packet loss and latency, install the MTR network tool on your Amazon Elastic Compute Cloud (Amazon EC2) instance that's in the VPC. It combines the functionality of traceroute and ping in a single network diagnostic tool. MTR provides a continuously updated output that lets you analyze network performance over time. Use MTR to check for ICMP or TCP packet loss and latency You can find resources utilization issues in values such as CPUUtilization, NetworkIn and NetworkOut, or NetworkPacketsIn and NetworkPacketsOut. To determine if you reached network limits, check the source and destination hosts for resource utilization issues. It's a best practice to isolate and confirm where the packet loss comes from. The causes of packet loss can vary as AWS VPN internet traffic moves between the on-premises network and Amazon VPC.
