Global Options
Global doveadm(1)
- -D
Enables verbosity and debug messages.
- -O
Do not read any config file, just use defaults. The dovecot_storage_version setting defaults to the latest version, but can be overridden with
- -k
Preserve entire environment for doveadm, not just import_environment setting.
- -v
Enables verbosity, including progress counter.
- -i instance-name
If using multiple Dovecot instances, choose the config file based on this instance name.
See instance_name setting for more information.
- -c config-file
Read configuration from the given config-file. By default it first reads config socket, and then falls back to /etc/dovecot/dovecot.conf. You can also point this to config socket of some instance running compatible version.
- -o setting=value
Overrides the configuration setting from /etc/dovecot/dovecot.conf and from the userdb with the given value. In order to override multiple settings, the -o option may be specified multiple times.
Commands
log errors
doveadm [Global Options] log errors [-s min_timestamp]
The log errors command is used to show the last - up to 1,000 - errors and warnings. If no output is generated, no errors have occurred since the last start.
- -s min_timestamp
An integer value, representing seconds since the epoch - also known as Unix timestamp. When a min_timestamp was given, doveadm(1) will only show errors occurred since that point in time.
log find
doveadm [Global Options] log find [directory]
command is used to show the location of the log files, to which dovecot(1) logs its messages through
log reopen
doveadm [Global Options] log reopen
This command causes doveadm to send a SIGUSR1 signal to master process, which causes it to reopen all log files configured in the log_path, info_log_path and debug_log_path settings. These settings are configured in /etc/dovecot/conf.d/10-logging.conf.
The master process also signals the log process to do the same. This is mainly useful after manually rotating the log files.
log test
doveadm [Global Options] log test
This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files. The used priorities are: debug, info, warning, error and fatal.
Example
This example shows how to locate the log files used by dovecot(1):
doveadm log find
Looking for log files from /var/log Debug: /var/log/dovecot.debug Info: /var/log/mail.log Warning: /var/log/mail.log Error: /var/log/mail.log Fatal: /var/log/mail.log
