System Logging (Syslog) servers are helpful for monitoring and managing different network devices. 

When it comes to monitoring your entire organization network, everyone seeks the best solution. 

If one network is down, devices in the network will start showing some issues. 

Thus, it is necessary to monitor your network devices from a single location to know the issues faster and resolve them better. 

Although, it can be done manually by checking each device’s log messages, running them, and finding the root cause. But, this process is tiresome and time-consuming. 

For this, Syslog servers work with Syslog protocols to facilitate efficient log management and tracking. 

Let’s understand what a Syslog server is, its features, and the best one for your organization.  

What Is Syslog?

Source: Paessler

A Syslog (System Logging) is a technology used to enable your enterprise devices within the network to send log messages about recent events to the server where the devices are logged. The log acts as a record room for all the events throughout the infrastructure. This will allow you to view the events on a large scale of devices through a single system. 

A Syslog server collects the messages from devices, such as a virtual machine, software service, or bare metal server. This data is then compiled in a single place. An administrator uses that information to monitor the entire network’s performance. 

Syslog servers consist of the following: 

  • A Syslog listener that receives the incoming data and interprets them
  • A database to store all the information
  • A filtering system to filter log messages

How Does a Syslog Server Work?

Syslog servers have a client-server architecture where the server receives log messages. It then forwards local messages to the remote analytics server via Syslog, commonly known as a standard industrial logging solution. 

Syslog traffic uses UDP port 514 by default. But, some network devices send data via TCP 1468 to ensure the message is delivered to the right place.

Syslog defines three layers:

  • Syslog content layer: It contains actual data in the event messages. It has some informational elements, including the severity levels and facility codes. 
  • Syslog application layer: It generates, routes, interprets, and stores messages. 
  • Syslog transport layer: It transmits messages over the network. 

It sends messages in this format:

seq:timestamp: %facility-severity-MNEMONIC:description

The terms mean:

  • Seq: Sequence number that indicates the order of the message.
  • Timestamp: It indicates the time message was generated.
  • Facility: It is a value that shows which process on your device generates the message.
  • Severity: It is a number that defines the severity of the event.
  • MNEMONIC: It is a short code used for messages, indicating what has happened. 
  • Description: It is detailed information about the event. 

Important Syslog Server Features


Before choosing any Syslog server, ensure it has the following features:

  • Collection and monitoring of Syslog messages
  • Syslog and log viewer for Windows
  • Log collection
  • Log archiving
  • Network troubleshooting
  • Server log monitoring
  • SNMP trap monitoring
  • Syslog management
  • Application auditing
  • IT compliance management
  • Threat and security analysis
  • Cross-platform audit

Now, let’s check out some of the best Syslog servers for effective networking management.
