How PRTG works as a syslog server
PRTG captures, processes, and analyzes essential data
Capture & display
As soon as PRTG receives syslog messages, PRTG syslog receiver displays all relevant information: including the IP address that the message was sent from, the time stamp of the message, and the message itself.
Process & analyze
As a syslog server, PRTG analyzes the severity level of receive syslog messages to check for potential emergencies, ranging from 0 (emergency) to 7 (debug). PRTG even reads and processes the facility code so that you can immediately identify the type of message that was sent.
PRTG in action as a syslog server
Visualize syslog message data in real time
PRTG makes it easy to visualize syslog message data in real time to get insights into application availability, performance, resource usage, and errors. Easily identify the syslog entries related to the root cause of the problem and address issues before they affect network performance.
PRTG is compatible with all major vendors & manufacturers

Use cases: Has PRTG the right syslog server features for you?
I don't need bells and whistles, I just need a free syslog server.
If you need a free, easy to set up solution for monitoring, storing, and analyzing syslog messages, then the freeware edition of PRTG is ideal. You'll even have sensors to spare and if your requirements change, you can quickly increase your capabilities at any time.
I need a professional network monitoring tool but I don't have the budget.
Many sysadmins would like to use a professional network monitoring tool but don't have the budget to do so. Getting management to free up the necessary funds can be time-consuming and stressful. Often it's a lot easier to use a free tool. PRTG makes this possible by including 100 free sensors that never expire.
I just want a syslog server for my home network.
Have you ever sat at home in front of your computer and wondered how to set up a syslog server for your home network? You're not alone. Many sysadmins also want reliable software for their homes. The syslog server features of PRTG can be useful for any network.
How to set up the Paessler PRTG syslog receiver
Choose from two easy PRTG syslog server configurations. You get 100 free sensors with the freeware edition of PRTG Network Monitor and up to 10,000 sensors with our paid licenses.
Option 1: Centralized Syslog Receiver sensor
Create a centralized Syslog Receiver sensor on the probe device of the free PRTG network monitoring software. It will capture and analyze the contents of all syslog messages sent from your entire system. If an error occurs or defined threshold values are exceeded, you'll receive automated real-time alerts.
Option 2: Device-specific Syslog Receiver sensor
Add each syslog message sender as a device in PRTG, then add a Syslog Receiver sensor to each of these new devices. Compared to option 1, you'll put less strain on your CPU but you'll need more sensors for it to work. That means your 100 free sensors may not be enough for in-depth monitoring.
How PRTG defines sensors
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
Keep a constant eye on your network – even while on the go
PRTG is set up in a matter of minutes and can be used on a wide variety of mobile devices.

Syslog stands for System Logging Protocol and is a standard protocol used to send system log or event messages to a specific server, called a syslog server.
It is primarily used to collect various device logs from several different machines in a central location for monitoring and review.
The protocol is enabled on most network equipment such as routers, switches, firewalls, and even some printers and scanners. In addition, syslog is available on Unix- and Linux-based systems and many web servers including Apache.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Syslog servers are also known as syslog collectors or syslog receivers.
Devices that are accordingly configured send syslog messages to the syslog receiver. For example, the IP address of the destination syslog server must be configured on the sending device. There is no mechanism within the syslog protocol that allows a server other than the one you configured to request syslog data.
While most Unix implementations and network vendors like Cisco have their own barebones syslog collectors, there are several others available, too.
Via the Syslog Receiver sensor, PRTG can be used as a basic syslog receiver that monitors, collects, and analyzes incoming syslog messages.
PRTG offers a preconfigured Syslog Receiver sensor. You can add this sensor either to the probe device of your PRTG installation to collect all syslog messages sent from your entire system. Or you can add the sensor to a specific device in PRTG to collect only syslogs sent from this device.
The sensor shows the following metrics:
- The number of received syslog messages
- The number of messages categorized as “warning”
- The number of messages categorized as “error”
- The number of dropped packets
You can set specific filter rules to only collect and analyze syslog messages that are business critical for you. This way, you will only be notified about alerts that you really want to know about.
