PRTG SNMP port analyzer: What you’ll find on this page
PRTG makes SNMP port analysis easy
Custom alerts and data visualizations make it easy to monitor, identify, and prevent port congestion, security vulnerabilities, and other network performance issues.
Are you expecting too much from your ports?
Emails that won't send. Frozen screens. Dropped connections.
Overloaded or underperforming ports cause all sorts of annoying and disruptive issues. And that's before we even talk about the security risks…
Paessler PRTG port analyzer uses SNMP to monitor the health of all ports across your network, so you can prevent outages, keep your colleagues productive, and shut bad actors out of your network.
Keep data flowing safely at speed with your SNMP port analyzer PRTG
Optimize your infrastructure
Manage your network and the communication between all elements in your infrastructure more effectively. PRTG works tirelessly in the background, tracking key stats and letting you know a port is close to overloading before it actually happens, so you can prevent outages.
Strengthen network security
With so much on your plate, potentially critical security issues can easily go unnoticed. PRTG keeps a close eye on switch ports, router ports, server ports, and other network infrastructure, rooting out weak spots like open ports before bad actors can exploit them.
Troubleshoot with ease
PRTG stores raw data for a year by default. That means you can go back as far as you need to pinpoint when a problem started. Plus, you can spot trends and take proactive action. Like ensuring you don't find yourself with too many devices and not enough ports.

Comprehensive port analysis on autopilot
PRTG's sophisticated, preconfigured sensors track individual ports – and your network as a whole.
SNMP Traffic sensor
Monitor traffic on a specific device with our SNMP Traffic sensor, including:
Port Range sensor
Keep an eye on all available TCP/IP ports within a specific range. PRTG's Port Range sensor tells you:
- The number of open ports
- The number of closed ports
- The time until requests to ports are accepted
Sensor Factory sensor
Unsure how many port channels are available on your network? Our Sensor Factory sensor is a custom sensor whose channels are based on data from other source sensors.
This way, you can work out averages and totals, so you don't have to check every port individually.

Analyze ports: FAQ
1. What is a port?
Ports are endpoints that make it easier for all the different processes and services on your network to talk to each other. When ports are working as they should, data flows freely and your network runs smoothly. But when ports are misconfigured or have other issues, they can slow your network down and make you more vulnerable to trojans and other security risks.
2. What's the difference between port monitoring and port scanning?
Port monitoring is like surveillance, while port scanning is an inspection. A port monitoring tool helps you track overall performance and identify long-term trends. A port scanner, on the other hand, is how you spot potentially imminent threats, such as ports that are open when they should be closed.
3. How does PRTG SNMP port analyzer work?
PRTG SNMP port analyzer continuously collects information about the ports on your network using SNMP. It can identify how many ports are open, how many are closed, which devices, applications, or other services are connected to them, and each port's response time.
4. How can I monitor ports using SNMP?
Monitoring ports using Simple Network Management Protocol (SNMP) involves configuring SNMP on the network devices and then using an SNMP port analyzer tool to collect and analyze data. Here are the general steps to monitor ports using SNMP:
- Enable SNMP on network devices:
- Access the device's management interface (often a web interface or command line).
- Locate the SNMP settings and enable SNMP.
- Configure SNMP community strings (read-only and read-write) for security.
2. Identify OIDs for port monitoring:
- Object Identifiers (OIDs) represent different parameters you can monitor with SNMP.
- Common OIDs for port monitoring are in the IF-MIB (Interface MIB). The main OID for interface statistics is ifTable (1.3.6.1.2.1.2.2).
3. Set up PRTG as your SNMP port analyzer:
- Install and configure PRTG’s sensors for port analysis with the SNMP community strings and target device IP addresses.
5. 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.
