Best Syslog Servers [Free Syslog Software & Tools of ] - Why should you choose WinSyslog?
Their power comes from the wide range of data that can be collected and, furthermore, the ways in which this data can be analyzed and levied for the sake of network maintenance, system monitoring, and dozens of other diagnostic and troubleshooting purposes!
Generally the Syslog protocol is supported by a wide variety of devices and thus it's easy for devices and applications to fire off log information to the Syslog server, which stores the information for further analysis. This enables an admin in the field to receive time-critical information, or to simply gets a heads up of something that may need attention soon.
Thanks to a built-in severity metric, it's easier to know when something can wait and when it can't. SNMP ties heavily into Syslog server functionality and can be used in tandem to poll all the wonderfully wide variety of information that admins are used to snatching up via SNMP.
However, when taken a step further via Syslogging server software, they can take that SNMP data and do a lot more with it — graphical interfaces which aggregate and monitor SNMP data, for example, can massively speed up the assessment of almost any number of critical systems or failure points. Using these same metrics many Syslog servers can also have automated scripts or events that will trigger and can potentially streamline the process of recovering from, or preventing, downtime or outages.
Some Syslog servers require client-based software to manage but many also offer web-based solutions, which can ease management both remotely or from different systems on a network environment. Most servers are also quite good at data management and will handle some level of archival functionality for saving older logs or records that may not actively be needed at present. Syslog does have a few drawbacks — it's not particularly standardized, meaning that sloppy implementation can cause troubles for Syslog servers, and it also lacks any kind of authentication.
In a trusted network environment this isn't really an issue, but especially nefarious malware or untrusted networks can sow seeds of trouble. Below is a list of software that performs these functions and more, as well as the compatible operating systems and, quite importantly, whether it supports some form of alert alarms, pop-ups, etc. Kiwi's Syslog Server boasts ease of installation and setup on top of its other range of desirable features.
Reports can be generated both in easy-to-read HTML or in plain text if necessary for parsing with other software. Log archival and storage are automatic and rigorous with a focus on compatibility in cases where even regulatory needs must be carefully met — even those as stringent as HIPAA.
Kiwi utilizes a web-based console for extremely ease of access and swift availability that requires no client installation or configuration. Kiwi's software even handles Syslog and SNMP, including from Linux and UNIX hosts, and performs real-time alerting and notification based on this data with a vast, and customizable, range of metrics that can be checked against. Editors' Choice!!! Primarily focuses on SNMP and Syslog protocol data and has a good amount of analysis ability due to the built-in capability PRTG already has for general monitoring and management.
Installed as a dedicated syslog server for all manner of network devices with a native support for a good range of notification options — SNMPSoft's program also boasts a particular ability to parse and handle non-standard Syslog, something that can cause some other software to falter!
Of particular note, there's also a Syslog Watcher VendorPack available, which is a huge reference of syslog messages for proprietary equipment that helps in swift troubleshooting by defining non-standard syslog messages automatically.
Not an ideal solution as even the Splunk forum will suggest using several Splunk servers for a proper setup, but still doable! Utilizing Splunk to index and manage log files is more strongly recommended, as syslog data will be lost with each Splunk restart by default.
None the less, it does offer syslog functionality and, with a little work getting several Splunks working together, can be a solid solution. The Dude, despite it's odd name, is an interesting and free option for general network management — it comes with a built-in syslog server which can be enabled with ease as well as provides functionality for remote logging via RouterOS. Log events can be filtered, sorted to different logs, or discarded based on customizable thresholds. It's breadth of coverage does mean less features, and overall the software is pretty cut and dry — which isn't always a bad thing!
Handles all basic Syslog message gathering and storage. A fairly simple and barebones Syslog server that also doubles as an analyzer. It can be adjusted to only log and monitor events at certain threshold values and also can trigger email-based notifications, as well as sort the way in which events are displayed. Icinga is a powerful open-source monitoring suite , and though its focus is on a wide breadth of monitoring, it does offer a plug-in specifically for Syslog monitoring and management.
Visual Syslog Server is a very straightforward and light-weight Syslog option that focuses on a real-time approach. It does have some ability to handle and rotate logs automatically, to avoid bloat, and can also trigger scripts or programs based on thresholds that can be set. It can handle notifications via email and also some alerting and automated triggering of actions!
Based on the BSD-unix style functionality of syslogd, this particular offering is going to appeal to only a select crowd! This software focuses on an enterprise level of functionality and is geared towards larger environments — it can gather and store a wide range of Syslog information and store it on a central database with a wide range of filters and alarms available.
Syslog tracking via a powerful Syslog server can save any network administrator an obscene amount of time and effort. Every bit of data, whether SNMP or Syslog, that can be requested, aggregated, and analyzed is another potential piece of a puzzle that can trigger alerts or notifications and quickly bring human attention to the problem as soon as possible, or even fire off predefined scripts or programs to alleviate, or at least slow down, oncoming issues.
The flexibility of these programs are a superb way for admins to leverage monitoring to their advantage with the goal of maximum uptime and stability. Much of this information can be seen on any one system or device, but even a small network with a few dozen devices would be totally unreasonable to monitor one by one — having it centralized, automated, and closely monitored is invaluable!
Most notably, Syslog servers are often capable of triggering alerts or sending notifications. Download FREE!

- 19 Best Syslog Server Tools for Windows & Linux (Free + Paid)
However, almost all devices need to be configured with their specific configuration tool. Typically, only two settings need to be made: one to activate Syslog messages at all and one with the Syslog server IP address or name. Remember : the computer running application now acts as a Syslog server.
As such, you need to find out its IP address or name and supply it to the device as the Syslog server. Please note that not all devices can operate with computer names. Use the IP address, if in doubt. Last updated by Jan Gerhards, using Winsyslog On screen, it looks as follows: Then, a wizard starts. Please select it in the tree view: As you can see, it has been created with the default parameters. Now you have a useable rule set for logging incoming messages to a text file.
Your screen should now look like this: As you can see, the service has been created with the default parameters. If another one is to be used, you can change it to another ruleset here you might have to scroll down to view the option : This procedure completes the configuration of the Syslog server. Step 3 — Re- Start the Service The application cannot dynamically read changed configurations.
These are highlighted in the screenshot below: The buttons resemble Windows service manager — start, stop and restart. Step 4 — Configure your Syslog-Enabled Devices Even though application is now ready, it can only receive messages if some devices send them.

This underlying system in Linux includes the rsyslog facility.
It is rsyslog that will perform your Syslog message gathering and storage functions. You can manage rsyslog through the Graylog interface.
If you pay for Graylog, you can also gather data through the Sidecar system. This allows you to store event logs on Windows computers. The front-end for Graylog is browser-based. This will display inputs by type, so you will be able to see your Syslog messages together in one section of the dashboard.
Widgets available for the dashboard include data visualization, such as histograms. The dashboard enables you to create your own alert conditions. You specify each alert based on a data stream type. For example, you can pick the Syslog UDP stream and then set up an alert condition on the number of warning messages that come through.
System settings enable you to get alerts sent to you as email notifications. Stream handling procedures enable you to parse records, forward them, or store them to file or database. The package is available as a bit or a bit application. The central element of this software is a TFTP client implementation. It is also able to receive Syslog data. This is a simple open-source utility that displays messages in the dashboard as they arrive.
Buttons over the viewer give you the ability to view messages by type and Syslog is one of the message types that can be featured. You see messages as they travel on their way to event logs and the viewer also names the file that Syslog messages should be stored to. However, you can also read in records from a file and then you have the ability to sort and filter messages. Usually, the client contacts the server and the server responds.
In syslog, the syslog client is just a program that broadcasts error, warning, and debugging messages. Syslogd is a daemon. This is a Syslog collector and so is judged to be the server, even though it never responds to the originator of the messages.
The daemon may be running locally, or it can also be implemented as a remote syslog server by connecting over the internet. Although the Syslog standard has been codified by the Internet Engineering Taskforce , there are so many implementations of Syslog that some variation in the syslog data message format exists. With all of the different message types you could be benefiting from, you need to get a tool to sort through them all.
However, there are open source Syslog server implementations out there. Syslog is also used by many network devices for error reporting. The Windows operating system has its own log messaging system, called Events.
You can unify these log file messages in one central location so security software, such as intrusion detection systems can get a system-wide view of events. Network equipment will automatically broadcast Syslog messages on the network. That means that any device can pick the messages up. The destination of messages on a Linux server is dictated by the syslogd or syslog-ng configuration file. Many excellent Syslog servers are written to run on Windows. The records in your syslog files are written there because the producers of your software and devices judged certain events to be of significance, so it is a mistake to ignore this rich source of system activity and status information.
So download a Syslog collector and activate it. This is caused by all of those Syslog event messages circulating around your network. UDP port is used by Syslog clients to send messages and also by Syslog servers to listen for messages.
Therefore it is both the source and destination port on all standard Syslog communications. Be suspicious of activity on TCP port This is a port known to be used by the ADM worm and it is not used for Syslog. There are secure Syslog implementations. A secure Syslog service needs to establish a connection, you cannot use a UDP port for them. If you want to operate a remote Syslog server connecting to a network across the internet, you need to go the Syslog over TLS route because unencrypted Syslog events being sent over the internet would seriously undermine your network security.
As you can see from the description of the tools in our list, you can choose a straightforward Syslog server, or opt for an analytical tool or a network monitoring system that incorporates Syslog server functions.
Beyond the basic functions of transferring Syslog messages to files, you can look for the capabilities to sort and filter messages. The ability to vary processing according to message types and drop debug messages and information notifications is useful. A programmer might need to see those debug messages, and so the ability to selectively direct message types to a viewer , a log file , or to a database can be very useful.
The evolution of Syslog processing to store records in a database rather than a file offers you great power. It is far easier to index, sort, search, and filter records in a database than it is to manipulate file records.
This is because databases include a structured query language that enables you to isolate fields in records and perform selection, grouping, and exclusion functions on data without altering the original stored records.
Another useful advancement in the Syslog servers available today is a system that can collect messages generated by other platforms and protocols , such as the Windows event logger. If your Syslog server can create standardized record formats , that takes you another step further along the route to collect important information about your system. Getting alerts created for the conditions reported by Syslog will also give you extra power to focus your energy on essential tasks.
The ability to create your own alert conditions represents an advancement in Syslog processing. Sometimes, the contents of a message might not create concern. However, a sudden surge in the frequency of such messages should become an alert and you can specify such conditions in many of the Syslog servers listed in this full review.
The ability to combine a count of message types or error conditions is another useful feature that many modern Syslog servers include. A Syslog server embedded in a network centralized management tool can provide excellent analysis capabilities. If you already have all the analytical tools you need, then you would be better off focusing on the vanilla Syslog server tools in this review. Managing IT services requires proper tools. Take a look at the free software recommended in this full review that fits your operating system.
Take a little time to play around with each tool so you can discover their features for yourself. Given that all of these tools are free, you have nothing to lose but the time it takes to learn them. The access method for a Syslog server depends on your operating system and the specific Syslog server that you chose to install.
On Linux, the Syslog server is more likely to be a command line utility. If you have a Linux flavor with a graphical interface, such as Ubuntu, you might be able to have a GUI Syslog server package. GUI interfaces are very common for Windows-based Syslog servers. In these cases, the installer may well have created a shortcut icon on your Desktop.
Syslog is a Linux utility, so it is better to create a Syslog server on a Linux machine:. Those are the basic steps to start collecting Syslog messages and storing them to a file.
You can get more sophisticated by adding in filters to direct messages to different files or add in explanations of each recorded event. Create a mnemonic to remember these. Take the first letter of each level type and make a memorable phrase with words that start with the same first letters.
A Syslog server receives files sent by Syslog clients or sends out files in response to requests. The files are formatted following a protocol called Syslog, which defines the fields in each log message. I use Syslog Watcher because it is effective for collecting and storing syslog messages from your router. It is great for managing all of your system messages on one computer.
I really like the control dashboard as it gives you several options on how to process messages. SylogWatcher is a great product. There are few products out there that have such a clean interface. However, Syslog Watcher originally obtained under SnmpSoft Company guise has remained the installed product which has fitted with my requirements. Easy to remove some noise from the displayed list. Drill down to logs for a particular device? Thank you so much for your help with this.
Business users can get a day money-back guarantee, however. I have tried multiple Syslog Servers, and my favorite one without a doubt is the Syslog Watcher. The thing I like the most is the ease of filtering messages. You guys you tried it out! Unlike SNMP , syslog cannot be used to poll devices for information; the syslog standard is used only to send messages about events. For troubleshooting purposes, syslog sending is potentially more effective than SNMP polling because syslog messages are sent and received immediately after an event occurs.
Polling information is received at intervals — events can occur quickly and cause a lot of damage in the short amount of time between polling intervals. For each device that you wish to have send its event logs to your syslog server, you need to ensure that its remote-syslog service is enabled and that it is pointed at the IP address of your server. Take note that the Syslog default port is UDP ; each sending device and the receiving Syslog collector need to be able to access this port.
Grab one of the following Free Syslog Servers below to keep an eye on your network with further detail from a centralized location, many of these can also be installed on Windows 7, 8. We reviewed the market for free Syslog servers and analyzed the tools based on the following criteria:. With these selection criteria in mind, we have discovered some really useful Syslog management utilities that we are happy to recommend and explain how you can get them for free.
Created by the industry-leading network management software developer SolarWinds, Kiwi Syslog Server is a comprehensive logging tool that collects syslog events and messages not only from network devices, but also Linux, Unix, and Windows systems. The free edition lets you collect and monitor syslog messages from up to 5 devices and lets you set up alerts for events such as heavy traffic, unauthorized login attempt, hardware failure, and more.
Kiwi also creates trend graphics, such as network traffic trends, and also creates a daily summary email for you. Finally, you can archive all these syslog messages as well as forward them to a database or other syslog systems.
The full version of Kiwi Syslog Server allows you to set up actions, such as run program or play sound, that are triggered by certain log events; it also comes with a web-based interface that lets you manage the syslog server remotely. Kiwi Syslog Server Free Edition is our top pick for a free Syslog server because it is a competent and useful tool that is free forever with no strings attached. This Syslog server is easy to install and set up and will work with just about any log file collector.
By sticking to well-known networking protocols, this server has no tricks or tie-ins and will work without fuss. Nice features include conditional forwarding, automated log file rotation, and crisis alerts. Syslog server functionality is built into the PRTG Network Monitor application, which we discussed in our previous article about netFlow collectors. PRTG is a full-featured network monitoring and management application that does not require additional software installation to activate the syslog server functionality.
PRTG boasts handling a very high number of syslog messages per second up to 10, in a lab setting ; however, your capabilities will depend on your processing power, storage, and configuration. Syslog events can be viewed and analyzed using the web interface. Information is displayed in an easy-to-understand interface and messages can be filtered according to the type of message, severity, and more. The filters can then be further refined to exclude or include messages, and categorize them as warnings or errors.
Alert triggers can be set up for specific types of messages, such as warnings or errors; you can also create an alert for when a high number of messages per second start coming in. The freeware version of PRTG allows for up to sensors.
