10 Best Free Syslog Servers for Linux and Windows

Best Free Syslog Servers for Linux and Windows

There are many different resources that can be used to provide information on network performance but few are as illustrative as syslog messages. Syslog servers allow network administrators to access syslog messages to conduct Quality of Service (QoS) monitoring. Syslog is essentially a protocol used to send event messages between different devices and applications on a network. These messages are vital for network monitoring because they provide you with important information.

For instance, you can use these messages to identify if your network is performing poorly or if you’re experiencing malicious activity. Syslog servers allow the user to access system logs and to use them to diagnose network problems. This is an application rather than a server which has the potential to access these messages.

In this article we’re going to look at some of the Best Free Syslog Servers for Linux and Windows.

SolarWinds Kiwi Syslog Server is one of the most convenient tools to use because it is accessible online. Online access means that this platform is low-maintenance in terms of deployment for larger organizations.

The great thing about SolarWinds Kiwi Syslog Server is that it acts as a syslog monitoring platform as well.

2. Paessler PRTG (FREE TRIAL)

PRTG Network Monitor

Paessler PRTG has generated a lot of attention as one of the most cost-effective network monitoring tools available. What is often overlooked is its aptitude for running syslog analysis. With a variety of unique sensors such as the Syslog Receiver sensor, PRTG can breakdown syslog messages and store them.

As a high-quality product PRTG allows you to configure alarms which are triggered based on the type of syslog messages the program receives. In the event that a serious issue is detected, the system will send you an alert to advise you to take action immediately.

There is also the option to filter which syslog messages you receive. You can do this by going to the sensor settings and entering your custom settings. This is beneficial because it allows you to cut down on the amount of raw information you see and to view something specific instead. Filtering what you see is one of the keys to monitoring a large body of syslog messages.

PRTG is a platform that is good for organizations of all sizes but excellent for smaller networks. There is a freeware version available for networks with less than 100 sensors. If this is not suitable for your needs, there are many different pricing options from $1600 (£1,207) for 500 sensors to $14500 (£10,945) for unlimited sensors.
