For example, check for loss on the last hop or destination, and then review the following hops. Review hops on traceroute or MTR reports using a bottom-up approach. Tcpdump to analyze packet capture samples.Hping3 to determine end-to-end TCP packet loss and latency problems.

Traceroute to determine latency or routing problems.MTR to check for ICMP or TCP packet loss and latency problems.AWSSupport-SetupIPMonitoringFromVPC to collect network metrics such as packet loss, latency, MTR, tcptraceroute, and tracepath.Install the following tools to help troubleshoot and test your network: Connect to your EC2 instance to access the instances and be sure that there's end-to-end connectivity between your EC2 instance and your on-premises host.If enhanced networking isn't turned on, see Enhanced networking on Linux or Enhanced networking on Windows. Enhanced networking provides higher I/O with low CPU utilization, which helps avoid instance-level issues when running performance tests. Use an EC2 instance that supports enhanced networking, and be sure that the drivers are up to date.Be sure that the network utilities are installed on both endpoints (on the EC2 instance and the on-premises host).It's a best practice to benchmark the performance results so that you can compare the results when you're observing the performance issues.īefore you begin troubleshooting, check the following: The following resolution can help determine if the source of the issue is a network or an application. To diagnose network issues such as packet loss or latency, first test the network to isolate the source of the issue.
