How to use Synology NAS as a Syslog Server (DSM 4)


By installing the Syslog Server package on a Synology DiskStation, you can easily set up your own syslog server to collect various types of activity logs from devices within the network. Syslog Server allows IT administrators to monitor the overall status of the multiple network devices with one interface and respond immediately should any problems occur.

This article will guide you through the process of setting up Syslog Server on your Synology DiskStation.

What is Syslog?
Syslog is a standard protocol for system data logging, allowing system logs to be transferred over a network. Syslog is widely supported on most of today's network devices. When a syslog client application is installed, a server can generate and feed logs to another server acting as the syslog server.
