Install the following tools to help troubleshoot and test your network:

• MTR to check for ICMP or TCP packet loss and latency problems.
• Traceroute to determine latency or routing problems.
• Hping3 to determine end-to-end TCP packet loss and latency problems.
• Tcpdump to analyze packet capture samples.

Review hops on traceroute or MTR reports using a bottom-up approach. For example, check for loss on the last hop/destination and then review the following hops. If the packet loss or latency issues continue through the last hop, there might be a network or routing issue. If you observe packet loss/latency on only one hop in the path, there might be an issue with the control plane rate limiting on that node. Check if the last hop reported is the destination noted in the command. If it isn't, there might be an issue caused by a restrictive security group.

Test performance using MTR

The Linux MTR command provides continual, updated output, allowing you to analyze network performance. It's a diagnostic tool that combines the functionality of traceroute and ping utilities. Most Linux distributions come with traceroute and MTR already installed. However, you can also download it from your distribution’s software package manager. To install MTR, run the following commands:
