# destination: Forward, send, and store log messages A destination is where a log message is sent if the filtering rules match. Similarly to sources, destinations consist of one or more drivers, each defining where and how messages are sent. Note If no drivers are defined for a destination, all messages sent to the destination are discarded. This is equivalent to omitting the destination from the log statement. To define a destination, add a destination statement to the `syslog-ng.conf` configuration file using the following syntax: ``` destination { destination-driver(params); destination-driver(params); ... }; ``` Note the following points: * Do not define the same drivers with the same parameters more than once, because it will cause problems. For example, do not open the same file in multiple destinations. * Do not use the same destination in different log paths, because it can cause problems with most destination types. Instead, use filters and log paths to avoid such situations. * Sources and destinations are initialized only when they are used in a log statement. For example, AxoSyslog starts listening on a port or starts polling a file only if the source is used in a log statement. For details on creating log statements, see [log: Filter and route log messages using log paths, flags, and filters](../docs/axosyslog-core/chapter-routing-filters/index.md). ## Example: A simple destination statement The following destination statement sends messages to the TCP port `1999` of the `10.1.2.3` host. ``` destination d_demo_tcp { network("10.1.2.3" port(1999)); }; ``` If name resolution is configured, you can use the hostname of the target server as well. ``` destination d_tcp { network("target_host" port(1999)); }; ``` The following destination drivers are available in AxoSyslog. If these destinations do not satisfy your needs, you can extend AxoSyslog and write your own destination, for example, in C, Java, or Python. For details, see [Write your own custom destination in Java or Python](../docs/axosyslog-core/chapter-destinations/reference-destination-custom/index.md). * * * [amqp: Publish messages using
