Appendix D: Log Level - Operations Conductor

Appendix D: Log Level

Operations Conductor enables you to change the log level of each microservice AWS Lambda function. To change the log level, you can change either the AWS CloudFormation stack parameter or each Lambda function’s environment variable.

AWS CloudFormation Stack Parameter

To change the entire log level of microservice Lambda functions, you can update the CloudFormation stack parameter. When you change the Log Level parameter and update the AWS CloudFormation stack, it will automatically deploy the new log level to all AWS Lambda functions.

Lambda Function Environment Variable

Each Lambda function has a LogLevel environment variable. To change the value, you can change only specific microservice Lambda function’s log level.

Supported Log Level

These are the supported log levels, and if you put other values, the microservice will change it to the default value, 2 (Info).

Parameters Log Level Description
0 Trace The minimum log level is trace
1 Debug The minimum log level is debug
2 Info The minimum log level is info
3 Warn The minimum log level is warn
4 Error The minimum log level is error
5 Fatal The minimum log level is fatal
