Syslog protocol is used by network devices/hosts to send messages over the network. SyslogGen is a tool for generating any syslog message. The tool supports the configuration of several syslog message parameters (e.g., facility or severity). SyslogGen can generate syslog messages for test purposes or for activating some action on the server side as a result of syslog message receiving. These can be identical messages with original syslog messages from network devices or from software products. In addition, it is possible to use this tool to send information through the network (e.g., notifications or logs).

With SyslogGen, it is easy to add syslog functionality to your own software products or command scripts (e.g., sending results). Simply run SyslogGen.exe with necessary parameters and send what you need.
