PRTG TCP monitoring: What you’ll find on this page
Do you have the full picture?
Monitoring traffic in real time can be tricky even on small networks.
But if you have distributed and virtualized traffic too, well… the challenge factor increases exponentially.
How do you set performance benchmarks in a scenario with so many moving parts? And how do you get a clear view of all the interdependencies that might impact your network's stability and performance?
Paessler PRTG solves these problems by gathering TCP data, TCP/IP data, and other critical metrics from across your network in one place, no matter how complex your setup.
Ideal whether you have a small on-premise network or a large infrastructure with data centers in multiple locations, it can monitor unlimited local, remote, and virtual devices, bringing critical system data together in one simple, intuitive interface you can access from anywhere, saving you time, effort, and headaches.
PRTG makes TCP monitoring as easy as it gets
Custom alerts and data visualization let you quickly identify and prevent low availability, high bandwidth use, downtime, and other network performance issues.
Why PRTG is the TCP monitoring tool of choice for savvy sysadmins
Simple setup
Easy to configure, and even easier to set up. Key in your preferred range of IP addresses and the automatic network discovery will detect connected devices and assign the right sensors. Each sensor is preconfigured, so it works out of the box. But you can customize its settings to suit.
Faster troubleshooting
You shouldn’t have to sift through terabytes of data to pinpoint issues. PRTG's monitoring dashboard brings together mission-critical data in one place, showing you what's going on in real time. And built-in automations alert you if there are issues, while you get on with other tasks.
Greater security
Your performance monitoring data (and network) are in safe hands. PRTG uses SSL encryption and other tough network security measures, including access rights management, SQL injection and cross-site scripting attack protection, and automated logout and re-authentication.
All-in-one monitoring
A clear (and complete) picture of your network in one single monitoring environment – not just TCP monitoring, but also SNMP, ICMP, WMI, SSH, and other protocols, hardware, applications... you get the idea. PRTG simplifies your workflow, saves time, and gives you peace of mind.
What TCP monitoring looks like in PRTG
Diagnose network issues by continuously tracking web, email, DNS servers, databases, routers, switches, firewalls, and other hardware and software components. Show connection times, latency, network traffic, and other key metrics in real time. Visualize monitoring data in clear topology maps and dashboards to identify problems more easily. Gain the overview you need to troubleshoot slow or failed connections, packet loss, and other network performance issues.
Start monitoring TCP ports with PRTG and see how it can make your network more reliable and your job easier.
Comprehensive TCP monitoring, without the effort
PRTG collects critical data about every device that's connected to your network round the clock, presenting it in easy-to-understand (and completely customizable graphs and dashboards).
That means performance monitoring and pinpointing what's causing an issue are as easy as it gets. PRTG will even alert you automatically if something isn't performing quite as it should.
PRTG's preconfigured TCP monitoring sensors include:
-
Port sensors for monitoring TCP port response times, as well as downtime
- Port v2 sensors for monitoring TCP port status (open or closed), downtime, errors, and response times
- Port Range sensors for monitoring how many TCP ports on your network are closed, the amount of downtime, and how long it takes for each port to accept a request
-
Ping v2 and Cloud Ping v2, for monitoring availability
Your TCP/IP monitor at a glance – even on the go
Set up PRTG in minutes and use it on almost any mobile device.
