Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Create a monitor in Network Flow Monitor

You create a monitor by providing the local and remote resources to monitor flows between. You can select network flows on the Workload insights page, and then choose to create a monitor. When you create a monitor in this way, the Create monitor wizard pre-populates local and remote resources for you. Alternatively, you can choose Create monitor, and then select local and remote resources for the monitor from drop-down menus.

By reviewing the top contributors on Workload insights on an ongoing basis, you can regularly evaluate if you have the monitors that you need, or if creating new monitors would be helpful.

To create a monitor using the console

  1. Open the CloudWatch console at https://console.amazonaws.cn/cloudwatch/.

    If you started by choosing specific network flows that you wanted to monitor on the Workload insights page before starting the Create monitor process, network flows are pre-populated for you. If you like, modify your original choices by selecting resources to add or remove in this step.

  6. Select the remote resources for the network flows that you want to monitor. To monitor all network flows that originate with the local resources that you chose, select Everywhere.

    If you want to select specific resources for your remote resources and your scope includes multiple accounts, choose an account for the resources that you want to specify. Then, choose Subnet, VPC, or Availability Zone, and then choose a resource.

  7. Optionally, you can add a tag for your monitor.

  8. When you're finished adding remote and local resources, choose Next to review and confirm the network flows to monitor.
