17 Best Syslog Servers for Windows and Linux

the ultimate list of syslog servers for windows and linux

When it comes to network monitoring, Syslog (System Logging) tools are a vital piece of any serious network administrator’s toolkit. Every minute devices from computers to printers generate syslog messages about a variety of events. For years network administrators have used these messages to monitor enterprise-scale IT infrastructure from the top down.

In most cases these events are innocuous yet sometimes they identify serious faults within an organization’s IT setup. Syslog servers take the information generated by these systems and compile it in one place where it can be used by an administrator to monitor the network’s performance. In this article, we guide you through what a Syslog server is before breaking down our ultimate list of Syslog servers for Windows and Linux.

What is Syslog?

As mentioned above, a syslog enables devices within your network to send messages about ongoing events to a syslog server where they are logged. This log acts as a record of active events throughout your IT infrastructure and allows you to view events on a large number of devices through one system and one pane of glass.

A syslog server works by taking log messages from your IT equipment and storing it in a centralized location where it can be viewed by a network administrator. Syslog servers are completely supported on Linux, Unix and MacOS systems. On Windows, Syslog can be supported through the use of third party applications as well. In terms of core components, most Syslog servers have:

  • A Syslog Listener – Takes data from Syslog messages sent to UDP port 514 and stores it in a centralized location
  • An Internal Database – The best Syslog servers store syslog data within an internal database.
  • A Filtering system – Filtering log messages will cut down the amount of time needed to sift through all this data.

Syslog server features

A typical Syslog server will help your network administration tasks by performing the following tasks:

  • Collecting syslog messages from different device types
  • Performing cross-platform functions to spot message that arise from any operating system
  • Provide a central storage point for all Syslog messages that arise on a WAN
  • Create a logical directory structure to aid access to historical Syslog data
  • Impose a standard file format for event logs
  • Enable live messages to be viewed
  • Provide a viewer for historical data loaded from file

The number of Syslog servers available today shows that this is a busy market. Competing providers are making their servers increasingly sophisticated, so now it is possible to get extra Syslog management features even from free Syslog servers. Look out for bonus features. Some Syslog servers can provide these services:

  • Analyze the frequency of Syslog messages by source type and warning severity
  • Display alerts in the dashboard and/or issue notifications by email
  • Trigger actions in the event of an alert condition arising
  • Consolidate other system warnings into a multi-source monitoring system
  • Integrate SNMP statuses into event log monitoring
  • Include graphical data representations in the dashboard.

The capabilities of a Syslog server can range from a simple message trap that writes to a file through to an event alerting and analysis tool.

Why Do I Need A Syslog Server?

Syslog servers are an essential tool for maintaining a clear view of an enterprise-scale network. Rather than sifting through Syslog messages on individual devices you can use a Syslog server to pull data from hundreds of disparate devices and access all these messages in one place. Without a syslog server, you’d have to check through each device individually.

The biggest advantage of a Syslog server is that it reduces manual network management time. You can simply check the Syslog server and read through the Syslog event messages generated by your entire network. This not only gives you a clearer view of what’s going on but makes your network monitoring more efficient as well. Below we break down some of the best Syslog Servers for Windows and Linux.

ryslog server

If you’re looking for a quality Syslog server for Linux, Rsyslog is a great option for individual users and enterprises alike. Rsyslog is an open source program that provides a range of log management options. Rsyslog is most commonly used through CentOS or RHEL 7. If you’re running a CentOS 7 system you don’t even need to download Rsyslog.

The main draw of Ryslog is that it is a powerful and versatile program. It can take log information from almost any device while monitoring up to 1 million messages per second.

Unfortunately, Ryslog’s lack of support for Windows users makes it unsuitable for cross-platform environments. That being said, if you’re on Linux this program is well worth consideration.

TFTPD32 Syslog Server

The catchily named TFTPD32/64 is an open-source Windows utility that also functions as a handy Syslog collection tool. It can receive Syslog messages and other event information from DHCP, DNS and SNTP servers. All your event messages will be stored in files where they can be viewed by the network administrator.

In terms of functionality, TFTPD doesn’t have that much more to offer.
