Logging

• We use DAZN Lambda Powertools as the error logging tool.
• Environment variable LOG_LEVEL has 4 values:
• DEBUG - Display all logs
• INFO - Display Log.info() logs and above
• WARN - Display Log.warn() logs and above
• ERROR - Display Log.error() only
• Environment variable SAMPLE_DEBUG_LOG_RATE controls the sampling rate of debug logs
• By default it is 0.01, that means we will log debug logs for 1% of the requests
• If we wanna enable debug logs for all services that is related to the current service, we can change it to 1. Note: Remember to change it back to 0.01 after debugging, as this will increase the AWS cost
