Enabling Amazon CloudWatch on a New Amazon EC2 Instance

This section describes how to enable monitoring when running a new instance.

Command Line Tools

To launch an instance

  1. Use the ec2-run-instances command.

    PROMPT>  ec2-run-instances ami-235fba4a -k gsg-keypair --monitored

    Amazon EC2 returns output similar to the following example.

    RESERVATION     r-7430c31d      924417782495    default
INSTANCE        i-ae0bf0c7      ami-2bb65342    pending gsg-keypair   0    m1.small    2008-03-21T16:19:25+0000        us-east-1a    monitoring-enabled

  2. Verify that monitoring is enabled for the instance. The instance starts running in a few minutes.

  3. The following command displays the launch status of the instance. 

    PROMPT>  ec2-describe-instances i-ae0bf0c7 
RESERVATION     r-7430c31d      924417782495    default
INSTANCE        i-ae0bf0c7      ami-2bb65342    ec2-67-202-7-236.compute-1.amazonaws.com        ip-10-251-31-162.ec2.internal   running gsg-keypair     0               m1.small        2008-03-21T16:19:25+0000us-east-1a    monitoring-enabled

After launching an instance, you are billed hourly for running time. When you are finished, make sure to terminate any instances that you started.
