This topic describes how to resolve the issue of unexpectedly high traffic over the internal network for Elastic Compute Service (ECS) instances.
If no ECS instances transmit data to the ECS instance but the traffic over the internal network is high, the ECS instance may be infected with viruses, which cause the ECS instance to forward a large number of packets. For more information about how to resolve the issue in this case, see Solution.
Note The NetHogs tool is an open source command line interface (CLI), which is similar to the top command in the Linux operating system. The NetHogs tool is used to analyze the real-time bandwidth usage of processes or applications.
- Download the NetHogs tool.
- Run the following command to install the NetHogs tool:
yum install nethogs
- Run the following command to view the internal bandwidth usage of each process:
Note If the ECS instance runs Windows Server 2008 or later, you can view the internal bandwidth usage of processes in Resource Monitor.
- On the ECS instance, right-click the taskbar and select Task Manager.
- On the Process tab of the Task Manager dialog box, view the internal bandwidth usage of processes.
