Syslog Monitoring

Warning! The Syslog monitoring is supported in LANState Pro only.

arrow Syslog is a standard for computer data logging. It is used on computer networks based on the TCP/IP protocol.

The Syslog protocol is simple. A sender sends a short message (not longer than 1024 bytes) to a recipient. The message can be sent via the UDP or TCP protocol. Syslog can be used for computer system management and security auditing. It is supported by a wide variety of devices (like printers and routers) and receivers across multiple platforms. Because of this, syslog can be used to integrate log data from many different types of systems into a central repository.

The program can receive Syslog messages and alert a network administrator about them using a variety of methods. To enable the Syslog receiving function, select the "Monitoring | Syslog monitoring" menu item. On the Syslog Monitoring window, you can configure whether the program should Receive all Syslog records or Receive records satisfying filters (and configure these filters). Here, you can also change the Syslog receiving Port. The default Syslog port is UDP 514.

arrow If there are many devices sending Syslog messages on your network, you can configure a trap filter which will allow you to filter our unnecessary and unimportant messages. To configure a filter, select the Receive records satisfying at least one condition option and click Add.

For example, to receive Syslog records from only one host you can select the Sender's IP address option and define the host's IP address. If you select the Text option the program will search the entered text in each received message and alert you only when the text is contained in the message.

arrow To configure notifications for Syslog records received, click the Configure alerts... button (See Fig. 1).

The notification methods are the same as when you are adding and configuring monitoring checks.
