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 (FREE TRIAL)
- Paessler PRTG (FREE TRIAL)
- ManageEngine EventLog Analyzer
- Icinga 2
- The Dude
- Visual Syslog Server
- SNMPSoft Syslog Watcher
- WhatsUp Syslog Server
SolarWinds Kiwi Syslog Server is a nimble syslog server for Windows that allows users to access their syslog messages through one centralized interface. 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. You receive alerts in real-time based on what information is found in your syslog messages. This means that you don’t have to manually read through all the syslog messages to know what is happening as the program will keep you updated automatically. Alerts eliminate the hassle of trying to monitor your syslog messages on an ongoing basis.
If you want to take a proactive approach towards managing your Syslog messages you can do so in SolarWinds Kiwi Syslog Server by scheduling reports. These reports will be sent to your email address detailing all the latest events on your network. Having reports available through your email makes it easier to consult your records about what is happening as well as being able to pass information along to other members of your team.
Volume is another thing that this tool does very well. It is not uncommon for syslog servers to get overwhelmed with the volume of data generated by larger networks. SolarWinds Kiwi Syslog Server has advanced message buffering which supports up to 10 million syslog messages and 1,000 email messages. In addition once you’ve taken your data onboard you can filter it by host name, host IP address, and time of day to make it easier to find. This supports larger organizations nicely.
SolarWinds Kiwi Syslog Server is our top pick for enterprises looking to monitor their syslog messages on an ongoing basis. Whether you’re dealing with a large network or a small one, this program has the resources to support you. SolarWinds Kiwi Syslog Server can be downloaded for $295 (£222) per install. There is also a 14-day free trial which can be downloaded from this link here.
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. This effectively prompts you to action rather than having to rely on your own observational skills alone.
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. A comprehensive list of pricing options can be found here. Alternatively, you can download a free trial from this link here.

The autodiscovery feature automatically recognises devices in the connected network and registers them in the system. This is good news for administrators because they don’t have to configure everything manually.
One of the appeals of this product is that it has built-in security measures. For example, log data is encrypted to make sure that unauthorized entities can’t get hold of it.

5. The Dude
MikroTik’s The Dude is a network monitoring application that has been one of the go-to tools of network administrators for quite some time. The Dude has its own syslog server which enables the user to conduct remote logging (through the use of RouterOS). As a network monitor with syslog monitoring capability this is a great choice for organizations operating on a shoestring budget.
Even though the The Dude has a basic design it functions well for monitoring syslog messages. This is mainly because you can filter logs to determine what you see when searching through your data. Filtering is an essential part of The Dude because it allows you to focus on specific messages rather than getting bombarded with everything.
As a network monitor The Dude is surprisingly well-made. You are supported by an autodiscovery feature which automatically identifies devices throughout your network. Autodiscovery eliminates the need to manually configure network devices. With regards to monitoring ability, The Dude supports a healthy spread of SNMP, ICMP, DNS, and TCP monitoring.
While The Dude isn’t a state of the art program by any means, it delivers a reliable network monitoring experience that lends well to syslog management. The Dude is available for Windows, Mac OS, Darwine, and in a Linux Wine environment. You can download The Dude from this link here.
6. Visual Syslog Server
Visual Syslog Server is a syslog server that takes an old school approach towards syslog monitoring. With Visual Syslog Server you can view syslog servers live as they come in. This platforms accepts messages from devices via UDP and TCP. Once messages are received they are stored on a disk. The clearcut storage keeps your previous syslog messages within reach for future analysis.
You can also use Visual Syslog Server to filter your syslog messages based on what you’re looking for. You can filter based on host, source address, priority, facility, or message content. This ensures that you’re able to separate the trees from the forest when dealing with a large volume of data.
Another useful feature is that of notifications. Whenever a message has been received that might need a quick response you are sent an email notification. Likewise, there is also a Show Alarms window so you can keep on top of alerts as they come in and respond to the most pressing issues first.
Visual Syslog Server doesn’t have a stunning interface, but it monitors syslog messages just fine. Visual Syslog Server can be downloaded for Windows XP and up, as well as Windows Server, 2003, 2008, and 2012. Visual Syslog Server can be downloaded for free from this link here.
