General Error Handling and Logging across COSMOS components

Logging Requirements

  • We would like to have consistency from the log to the component to the code
    • We should also be consistent in identification, including the instance identifier
    • Tie the instance identifier to the management endpoint (WSDM) that can be used to control the component
  • What is the structure of the logs--a physical view?
  • Need to define the "logging architecture"
  • Tracing/Logging levels
  • Need to have description of error log.
  • Would like to have one logical view of the log.
  • Standardized log format
    • Do we choose CBE or WEF
  • Symptoms

Error/Exceptions Requirement

  • Must log these
