###               ejabberd configuration file
###
###

### The parameters used in this configuration file are explained in more detail
### in the ejabberd Installation and Operation Guide.
### Please consult the Guide in case of doubts, it is included with
### your copy of ejabberd, and is also available online at
### http://www.process-one.net/en/ejabberd/docs/

### The configuration file is written in YAML.
### Refer to http://en.wikipedia.org/wiki/YAML for the brief description.
### However, ejabberd treats different literals as different types:
###
### - unquoted or single-quoted strings. They are called "atoms".
###   Example: dog, 'Jupiter', '3.14159', YELLOW
###
### - numeric literals. Example: 3, -45.0, .0
###
### - quoted or folded strings.
###   Examples of quoted string: "Lizzard", "orange".
###   Example of folded string:
###   > Art thou not Romeo,
###     and a Montague?

###   =======
###   LOGGING

##
## loglevel: Verbosity of log files generated by ejabberd.
## 0: No ejabberd log at all (not recommended)
## 1: Critical
## 2: Error
## 3: Warning
## 4: Info
## 5: Debug
##
loglevel: 4

##
## rotation: Describe how to rotate logs. Either size and/or date can trigger
## log rotation. Setting count to N keeps N rotated logs. Setting count to 0
## does not disable rotation, it instead rotates the file and keeps no previous
## versions around. Setting size to X rotate log when it reaches X bytes.
## To disable rotation set the size to 0 and the date to ""
## Date syntax is taken from the syntax newsyslog uses in newsyslog.conf.
## Some examples:
##  $D0     rotate every night at midnight
##  $D23    rotate every day at 23:00 hr
##  $W0D23  rotate every week on Sunday at 23:00 hr
##  $W5D16  rotate every week on Friday at 16:00 hr
##  $M1D0   rotate on the first day of every month at midnight
##  $M5D6   rotate on every 5th day of the month at 6:00 hr
##
log_rotate_size: 10485760
log_rotate_date: ""
log_rotate_count: 1

##
## overload protection: If you want to limit the number of messages per second
## allowed from error_logger, which is a good idea if you want to avoid a flood
## of messages when system is overloaded, you can set a limit.
## 100 is ejabberd's default.
log_rate_limit: 100

##
## watchdog_admins: Only useful for developers: if an ejabberd process
## consumes a lot of memory, send live notifications to these XMPP
## accounts.
##
## watchdog_admins:
##   - "bob@example.com"


###   ================
###   SERVED HOSTNAMES

##
## hosts: Domains served by ejabberd.
## You can define one or several, for example:
## hosts:
##   - "example.net"
##   - "example.com"
##   - "example.org"
##
hosts:
  - "localhost"

##
## route_subdomains: Delegate subdomains to other XMPP servers.
## For example, if this ejabberd serves example.org and you want
## to allow communication with an XMPP server called im.example.org.
##
## route_subdomains: s2s

###   DATABASE SETUP

## ejabberd by default uses the internal Mnesia database,
## so you do not necessarily need this section.
## This section provides configuration examples in case
## you want to use other database backends.
## Please consult the ejabberd Guide for details on database creation.

##
## MySQL server:
##
## odbc_type: mysql
## odbc_server: "server"

## odbc_username: "username"
## odbc_password: "password"
##
## If you want to specify the port:

## faster but inexact replacement for "select count(*) from users"
##
## pgsql_users_number_estimate: true
