marbot-elastic-beanstalk.config

# Setup instructions
# 1. In your Elastic Beanstalk project's source code, create a folder .ebextensions (learn more https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/ebextensions.html).
# 2. Copy this file into the .ebextensions folder (file must end with .config!).
# 3. Adjust the MarbotEndpointId option_settings.
# 4. Deploy the application.

option_settings:
  aws:elasticbeanstalk:customoption:
    # Your marbot endpoint ID (to get this value: select a channel where marbot belongs to and send a message like this: "@marbot show me my endpoint id").
    MarbotEndpointId: ''

    # The maximum percentage of CPU utilization.
    MarbotCPUUtilizationThreshold: 80

    # The minimum number of CPU credits available (t* instances only).
    MarbotCPUCreditBalanceThreshold: 20
