Unfortunately, when running on Docker, you won't experience the true glory of colored terminal output. (the traffic alerts are red, and recoveries are green)
LOG_FILE_PATH: Path to the logfile that the app will monitor. Defaults to /tmp/access.log
LOG_COUNT_PER_SECOND_ALARM_THRESHOLD: If the average number of logs seen during the LOG_CACHE_RETENTION_TIME_SECONDS is greater than this number, then an alarm will be set off.
REFRESH_LOOP_MS: Rate (in Milliseconds) at which the app should refresh the display, and clear short term stats. If you want short term stats to persist longer, increase this value. Defaults to 10 seconds (10000)
LOG_CACHE_RETENTION_TIME_SECONDS: Duration (in seconds) for which long term stats are retained. IMPORTANT: this also determines the threshold alarms. The default is 2 minutes (120). For testing purposes, it can be useful to decrease this amount. For example, if you want to test Traffic Alert Recoveries, but don't want to wait a full 2 minutes for logs to clear out, decrease this number.
RUN_LOG_MAKER_SERVER: If you want to spam some logs into the configured file, you can run this little server, which will listen on the LOG_MAKER_SERVER_PORT port. POST to localhost:LOG_MAKER_SERVER_PORT/count=[n] to send n logs into the file
LOG_MAKER_SERVER_PORT: port for the LOG MAKER SERVER. Defaults to 3000
DISREGARD_LOG_TIMESTAMP: When new logs are received with old timestamps, this determines whether to include them. Defaults to true.
