An example of how to use Golang's log/syslog package to send syslog messages to a particular syslog facility.
The repository also includes a sample Docker image that has an rsyslog server listening on port 514/udp forwarding any syslog messages sent to it to stdout.
Usage:
syslog-send [OPTIONS] Message...
Application Options:
--address= address of the syslog server (default: 127.0.0.1:514)
--transport= transport to use (tcp|udp) (default: udp)
--facility= name of the syslog facility to send msgs to (default: local0)
--severity= severity of the message (default: emerg)
Help Options:
-h, --help Show this help message
First, create the rsyslog server:
# The Makefile under the root of this repository
# contain a `docker-compose` file that builds the
# image at `./image` and then runs the container
# with the right port mapping in place.
make run
# Send a message to the rsyslog installation using
# the default parameters.
syslog-send this is a message!
# Check the logs from the rsyslog container to
# verify that we indeed received the message.
docker logs rsyslog
