4 ways our SNMP trap analyzer PRTG helps you monitor trap messages


Central overview of SNMP trap messages 

Paessler PRTG can collect all SNMP trap messages that are sent in your network, giving you a central overview of everything. Filter the traps by date, source, agents, and more to analyze your trap messages quickly and easily.

Immediate alerts and custom notifications

Define SNMP trap messages that represent critical events in your network and configure PRTG to trigger alerts when they occur. You can choose between several notification methods. This way, your IT teams know immediately when issues arise.


SNMP trap monitoring right out the box

With the preconfigured SNMP Trap Receiver sensor in PRTG, it’s fast and easy to start monitoring your SNMP trap messages. Just configure the target device so it can send SNMP traps, then add the sensor in PRTG and define the filters you need.


Flexible SNMP trap message monitoring

You can decide if you want to receive all SNMP trap messages generated in your network, or if you want to only receive certain message types or messages from specific devices. This helps you reduce alert noise and focus on what really matters.


What SNMP trap monitoring looks like in PRTG

Diagnose network issues by continuously receiving and analyzing SNMP trap messages. Show the status of SNMP traps in real time and visualize data in graphic maps & dashboards to identify problems more easily. Get alerted when SNMP trap messages communicate critical events.

PRTG as an SNMP trap receiver: powerful SNMP trap monitoring tool


 i 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.

The PRTG SNMP Trap Receiver sensor gives you all the information you need to make sense of what is going on in your network:


  • View and analyze each individual SNMP trap message, including the source, agent, bindings, and more
  • Customize the view of your SNMP trap messages by using comprehensive filters
  • See SNMP trap statistics, such as the total number of messages received, the number of messages dropped, errors, and more.
  • Get real-time alerts when SNMP trap messages that indicate critical events are received

Not just an SNMP trap receiver tool: PRTG can do way more for you

SNMP monitoring

PRTG comes with several preconfigured SNMP sensors, some of which have been designed especially for device manufacturers such as Cisco, Dell, and HPE. Keep an eye on the availability, health, and performance of your hardware.

Syslog monitoring

With PRTG, you can not only receive and analyze SNMP traps, but also syslog messages. Use PRTG as a kind of syslog server to collect all syslog messages sent from your system, and filter them according to granular rules to only be alerted to issues that matter.

Network traffic monitoring

Find out which applications and servers are putting the greatest strain on your network’s bandwidth. Monitor systems, devices, and applications and analyze your network traffic in detail using technologies like SNMP, packet sniffing, or flow protocols (NetFlow, jFlow, sFlow, IPFIX).




“Excellent tool for detailed monitoring. Alarms and notifications work greatly. Equipment addition is straight forward and server initial setup is very easy. ...feel safe to purchase it if you intend to monitor a large networking landscape.”

Monitoring SNMP trap messages: FAQ


1. What is an SNMP trap?

SNMP traps are one of the oldest standards for network equipment fault notification, and most network devices with basic management capabilities support SNMP traps. When a device detects an error or a change, the device sends a notification to one or more trap receivers.

2. What does an SNMP trap contain?

SNMP packets consist of a packet header, a PDU header, and a PDU body. For trap messages, the information sent in the PDU header can vary. The PDU header of an SNMP trap packet contains the packet types, the OID of the device, the IP address of the sender, general and company-specific IDs, and the time the trap event occurred. The actual values are sent in the PDU body.

3. How can I receive SNMP traps?

An SNMP Trap Receiver collects SNMP messages that are sent from network devices to the network management station. Monitored devices send SNMP traps that report incidents to the management system. PRTG can handle thousands of SNMP traps per second.

4. Will I need an SNMP trap server?

The term “trap server” is sometimes used synonymously with “trap receiver.” This server receives and processes messages. Our preconfigured sensor for monitoring SNMP traps lets you configure any PRTG probe device as an SNMP trap server. PRTG supports SNMP v1 traps as defined in RFC 1157, and SNMP v2c traps as outlined in RFC 3416.

5. Can PRTG analyze and display SNMP traps?

PRTG receives the traps, which include the number of messages received per second, warnings, errors, and lost data packets. PRTG presents trap content and messages in an easy-to-read table. Data can be filtered however you like.


6. How thoroughly are the SNMP traps analyzed?

With PRTG, you get a quick overview of the traps and their contents, and will be notified immediately in the event of a problem. If you need a more thorough analysis, various specialized tools will allow you to examine traps in detail.

7. Which port is used for the transmission of SNMP messages?

By default, SNMP traps are sent via UDP port 162. This port must be set as the destination port in your source devices.

8. What is the difference between Get, GetNext, Set, and Trap?

SNMP works on the assumption that a network management system submits a query, and a managed device returns an answer. There are four possibilities for this exchange: Get, GetNext, Set, and Trap.

With Trap, SNMP traps are automatically sent from a device to a compatible receiver – without the receiver requesting them. This is not the case with Get and GetNext. With these commands, queries are performed manually. Set is no traditional monitoring function.

9. Does the SNMP trap monitor work with Windows?

PRTG has always been developed for Windows systems, which means you can also set up your trap monitoring in Windows.

10. What is a sensor in PRTG?

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.
