👑 nova-scheduler(1) — like, the manual page, but make it make sense

okay bestie, gather round 💖 this is the nova-scheduler man page from the nova manual — yes THAT nova, the OpenStack one. no cap.

✨ NAME ✨

nova-scheduler — the server for the OpenStack Compute scheduler service. that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

nova-scheduler [<options>...]

🦋 DESCRIPTION 🦋

nova-scheduler is a server daemon, and it serves the Nova Scheduler service. and what does the Nova Scheduler service do, you ask? it picks a compute node for a given instance to run on. that's it. that's the job. it's the matchmaker of the cloud, fr fr — every instance needs a home and scheduler is out here playing cupid 💘 running as a daemon, serving, choosing. main character energy.

💅 OPTIONS 💅

General options

  • --config-dir DIR — path to a config directory, and it pulls all the *.conf files out of it. the file set gets sorted, so the parse order stays predictable when individual options get over-ridden. this set is parsed after the file(s) you gave via previous --config-file arguments, so any over-ridden options in the directory win. ⚠️ this option has to be set from the command-line, no sneaking it in elsewhere.
  • --config-file PATH — path to a config file to use. you can specify multiple config files, and values in later files take precedence. defaults to None. also must be set from the command-line, bestie.
  • --debug, -d — sets the logging level to DEBUG instead of the default INFO level. for when you wanna see EVERYTHING. 👀
  • --log-config-append PATH, --log-config PATH, --log_config PATH — the name of a logging configuration file. it gets appended to any existing logging configuration files. for the deets on logging configuration files, go look at the Python logging module documentation. heads up though: when logging configuration files are used, ALL logging configuration is set in the config file and the other logging configuration options get ignored (like, say, log-date-format). so pick a lane. 🚗
  • --log-date-format DATE_FORMAT — defines the format string for %(asctime)s in log records. Default: None. this option is ignored if log_config_append is set.
  • --log-dir LOG_DIR, --logdir LOG_DIR — (optional) the base directory used for relative log_file paths. ignored if log_config_append is set.
  • --log-file PATH, --logfile PATH — (optional) name of the log file to send logging output to. if no default is set, logging goes to stderr as defined by use_stderr. ignored if log_config_append is set.
  • --nodebug — the inverse of --debug. un-debug. 🙈
  • --nouse-journal — the inverse of --use-journal.
  • --nouse-json — the inverse of --use-json.
  • --nouse-syslog — the inverse of --use-syslog.
  • --nowatch-log-file — the inverse of --watch-log-file.
  • --syslog-log-facility SYSLOG_LOG_FACILITY — the syslog facility to receive log lines. ignored if log_config_append is set.
  • --use-journal — enables journald for logging. if you're running in a systemd environment you may wish to turn on journal support. doing so uses the journal native protocol, which includes structured metadata on top of the log messages (yes, extra lore 🌈). this option is ignored if log_config_append is set.
  • --use-json — uses JSON formatting for logging. ignored if log_config_append is set.
  • --use-syslog — uses syslog for logging. 🚨 the existing syslog format is DEPRECATED and will be changed later to honor RFC5424. this option is ignored if log_config_append is set.
  • --version — shows the program's version number and exits. bye 👋
  • --watch-log-file — uses a logging handler designed to watch the file system. when the log file gets moved or removed, this handler opens a new log file at the specified path instantaneously. it only makes sense if the log_file option is specified and you're on a Linux platform. ignored if log_config_append is set.
