## DESCRIPTION

This manual page documents briefly the `&dhpackage;` command.

This manual page was written for the &debian; distribution because the original program does not have a manual page.

`&dhpackage;` is a program that starts the Celery Worker Daemon.

## OPTIONS

This program follows the usual &gnu; command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.

`-c` `--concurrency`

- Number of child processes processing the queue. The default is the number of CPUs available on your system.

`-f` `--logfile`

- Path to log file. If no logfile is specified, stderr is used.

`-l` `--loglevel`

- Logging level, choose between DEBUG, INFO, WARNING, ERROR, CRITICAL, or FATAL.

`-n` `--hostname`

- Set custom hostname.

`-B` `--beat`

- Also run the celerybeat periodic task scheduler. Please note that there must only be one instance of this service.

`-E` `--events`

- Send events that can be captured by monitors like celerymon.

`--discard`

- Discard all waiting tasks before the daemon is started. WARNING: This is unrecoverable, and the tasks will be deleted from the messaging server.
