The Aurora/Thermos observer can take a variety of configuration options through command-line arguments. A list of the available options can be seen by running thermos_observer --long-help
.
Please refer to the Operator Configuration Guide for details on how to properly set the most important options.
$ thermos_observer.pex --long-help Options: -h, --help, --short-help show this help message and exit. --long-help show options from all registered modules, not just the __main__ module. --mesos-root=MESOS_ROOT The mesos root directory to search for Thermos executor sandboxes [default: /var/lib/mesos] --ip=IP The IP address the observer will bind to. [default: 0.0.0.0] --port=PORT The port on which the observer should listen. [default: 1338] --polling_interval_secs=POLLING_INTERVAL_SECS The number of seconds between observer refresh attempts.

[default: 20] --task_disk_collection_interval_secs=TASK_DISK_COLLECTION_INTERVAL_SECS The number of seconds between per task disk resource collections. [default: 60] --enable_mesos_disk_collector Delegate per task disk usage collection to agent. Should be enabled in conjunction to disk isolation in Mesos-agent. This is not compatible with an authenticated agent API. [default: False] --agent_api_url=AGENT_API_URL Mesos Agent API url. [default: http://localhost:5051/containers] --executor_id_json_path=EXECUTOR_ID_JSON_PATH `jmespath` to executor_id key in agent response json object. [default: executor_id] --disk_usage_json_path=DISK_USAGE_JSON_PATH `jmespath` to disk usage bytes value in agent response json object. [default: statistics.disk_used_bytes] From module twitter.common.app: --app_daemonize Daemonize this application. [default: False] --app_profile_output=FILENAME Dump the profiling output to a binary profiling format. [default: None] --app_daemon_stderr=TWITTER_COMMON_APP_DAEMON_STDERR Direct this app's stderr to this file if daemonized. [default: /dev/null] --app_debug Print extra debugging information during application initialization. [default: False] --app_rc_filename Print the filename for the rc file and quit. [default: False] --app_daemon_stdout=TWITTER_COMMON_APP_DAEMON_STDOUT Direct this app's stdout to this file if daemonized. [default: /dev/null] --app_profiling Run profiler on the code while it runs. Note this can cause slowdowns. [default: False] --app_ignore_rc_file Ignore default arguments from the rc file. [default: False] --app_pidfile=TWITTER_COMMON_APP_PIDFILE The pidfile to use if --app_daemonize is specified. [default: None] From module twitter.common.log.options: --log_to_stdout=[scheme:]LEVEL OBSOLETE - legacy flag, use --log_to_stderr instead. [default: ERROR] --log_to_stderr=[scheme:]LEVEL The level at which logging to stderr [default: ERROR]. Takes either LEVEL or scheme:LEVEL, where LEVEL is one of ['INFO', 'NONE', 'WARN', 'ERROR', 'DEBUG', 'FATAL'] and scheme is one of ['google', 'plain']. --log_to_disk=[scheme:]LEVEL The level at which logging to disk [default: INFO]. Takes either LEVEL or scheme:LEVEL, where LEVEL is one of ['INFO', 'NONE', 'WARN', 'ERROR', 'DEBUG', 'FATAL'] and scheme is one of ['google', 'plain']. --log_dir=DIR The directory into which log files will be generated [default: /var/tmp]. --log_simple Write a single log file rather than one log file per log level [default: False]. --log_to_scribe=[scheme:]LEVEL The level at which logging to scribe [default: NONE]. Takes either LEVEL or scheme:LEVEL, where LEVEL is one of ['INFO', 'NONE', 'WARN', 'ERROR', 'DEBUG', 'FATAL'] and scheme is one of ['google', 'plain']. --scribe_category=CATEGORY The category used when logging to the scribe daemon. [default: python_default]. --scribe_buffer Buffer messages when scribe is unavailable rather than dropping them. [default: False]. --scribe_host=HOST The host running the scribe daemon. [default: localhost]. --scribe_port=PORT The port used to connect to the scribe daemon. [default: 1463].
