CloudWatch Network Monitoring examples using Amazon CLI

The following code examples show you how to perform actions and implement common scenarios by using the Amazon Command Line Interface with CloudWatch Network Monitoring.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

The following code example shows how to use create-monitor.

Amazon CLI

Example 1: To create a network monitor with an aggregation period

The following create-monitor example creates a monitor named Example_NetworkMonitor with an aggregationPeriod set to 30 seconds. The initial state of the monitor will be INACTIVE because there are no probes associated with it. The state changes to ACTIVE only when probes are added. You can use the update-monitor or create-probe commands to add probes to this monitor.

aws networkmonitor create-monitor \ --monitor-name Example_NetworkMonitor \ --aggregation-period 30

Output:

{ "monitorArn": "arn:aws:networkmonitor:region:111122223333:monitor/Example_NetworkMonitor", "monitorName": "Example_NetworkMonitor", "state": "INACTIVE", "aggregationPeriod": 30, "tags": {} }

For more information, see How Amazon CloudWatch Network Monitor Works in the Amazon CloudWatch User Guide.

Example 2: To create a network monitor with a probe using TCP and also includes tags

The following create-monitor example creates a monitor named Example_NetworkMonitor. The command also creates one probe that uses the ICMP protocol and includes tags. Since no aggregationPeriod is passed in the request, 60 seconds is set as the default. The state of the monitor with the probe will be PENDING until the monitor is ACTIVE. This might take several minutes, at which point the state will change to ACTIVE, and you can start viewing CloudWatch metrics.

aws networkmonitor create-monitor \ --monitor-name Example_NetworkMonitor \ --probes sourceArn=arn:aws:ec2:region:111122223333:subnet/subnet-id,destination=10.0.0.100,destinationPort=80,protocol=TCP,packetSize=56,probeTags={Name=Probe1} \ --tags Monitor=Monitor1

Output:

{ "monitorArn": "arn:aws:networkmonitor:region111122223333:monitor/Example_NetworkMonitor", "monitorName": "Example_NetworkMonitor", "state": "PENDING", "aggregationPeriod": 60, "tags": { "Monitor": "Monitor1" } }

For more information, see How Amazon CloudWatch Network Monitor Works in the Amazon CloudWatch User Guide.

Example 3: To create a network monitor with a probe using ICMP and also includes tags

The following create-monitor example creates a monitor named Example_NetworkMonitor with an aggregationPeriod of 30 seconds. The command also creates one probe that uses the ICMP protocol and includes tags. Since no aggregationPeriod is passed in the request, 60 seconds is set as the default. The state of the monitor with the probe will be PENDING until the monitor is ACTIVE. This might take several minutes, at which point the state will change to ACTIVE, and you can start viewing CloudWatch metrics.

aws networkmonitor create-monitor \ --monitor-name Example_NetworkMonitor \ --aggregation-period 30 \ --probes sourceArn=arn:aws:ec2:region111122223333:subnet/subnet-id,destination=10.0.0.100,protocol=ICMP,packetSize=56,probeTags={Name=Probe1} \ --tags Monitor=Monitor1

Output:

{ "monitorArn": "arn:aws:networkmonitor:region:111122223333:monitor/Example_NetworkMonitor", "monitorName": "Example_NetworkMonitor", "state": "PENDING", "aggregationPeriod": 30, "tags": { "Monitor": "Monitor1" } }
