Probe dashboards - Amazon CloudWatch

Probe dashboards

You can use a Probe dashboard in Amazon CloudWatch Network Monitor to view the network health indicator (NHI) for a probe, as well as information about round-trip time and packet loss for specific probes. There are two dashboards for probes: an Overview page and Probe details page.

You can create CloudWatch alarms to set packet loss and round-trip time metric thresholds. When a threshold is reached for a metric, a CloudWatch alarm notifies you. For information on creating probe alarms, see Probe alarms.

To access a probe dashboard
  1. Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/, and then, under Network Monitoring, choose Network Monitor.

  2. In the Network monitors section, choose the Name link to open the dashboard for a specific monitor.

  3. To view the dashboard for a specific probe, choose the ID link for the probe.

Overview page

The Overview page displays the following information for a probe:

  • Network health — Network health displays the network health indicator (NHI) value, which pertains to health of only the AWS network. The NHI status is either Healthy or Degraded. A Healthy status indicates that Network Monitor did not observe issues with the AWS network for a probe. A Degraded status indicates that Network Monitor observed an issue with the AWS network. The status bar in this section shows the status of the network health indicator over a default time of one hour. Hover over any point in the status bar to view additional details.

  • Packet loss — The number of packets that were lost from the source subnet to the destination IP address for this probe.

  • Round-trip time — The time it takes, in milliseconds, for a packet from the source subnet to reach the destination IP address, and then come back again. Round-trip time (RTT) is the average RTT observed during the aggregation period.

Probe details

The Probe details page displays information about a probe, including the source and destination. You can also edit the probe, for example, to activate or deactivate it. For more information, see Working with monitors and probes in Network Monitor.

  • Probe details — This section provides general information about the probe, which can't be edited.

  • Probe source and destination — This section displays details about the probe. Choose a VPC or Subnet ID link to open the VPC or subnet details in the Amazon VPC Console. You can modify a probe, for example, to activate or deactivate it.

  • Tags — View the current tags for a monitor. You can add or remove tags by choosing Manage tags. This opens the Edit probe page. For more information on editing tags, see Edit a probe.
