Amazon CloudWatch

This solution creates the following CloudWatch rules and logs to invoke and log associated AWS Lambda functions.

CloudWatch Logs:

• /aws/lambda/transit-vpc-poller: Logged actions of the VGW Poller Lambda function

• /aws/lambda/ transit-vpc-cisco-configurator: Logged actions of the Cisco Configurator Lambda function

• /aws/lambda/transit-vpc-solution-helper-XXXXXXXXXXXXX or transit-vpc-poller-solution-helper-XXXXXXXXXXXXX: Created by the solution-helper customer resource when launching the transit-vpc-primary-account AWS CloudFormation template or the transit-vpc-poller AWS CloudFormation template.

CloudWatch Rule:

• vgw-poller-1min: This rule invokes the VGW Poller Lambda function every (1) minute.

This solution also logs debugging, informational, warning, error, and critical messages for the VGW Poller and Cisco Configurator Lambda functions. To choose the type of messages to log, find the applicable function in the Lambda console and change the LOG_LEVEL environment variable to the applicable type of message.
