Detect all port activity The port sniffer included within the PRTG network monitor tool detects all port activity in your network, as well as your system's application usage. All the data that is being sent and received through your network's ports can be easily monitored with PRTG. With PRTG and its included port sniffer, there is no need for additional port monitoring software. This advanced monitoring utility can capture, view, log, and analyze network data. You can use the port sniffer for data acquisition, connection & interface testing diagnostic analysis, packet analyzer and more.In addition, PRTG's port sniffer supports a wide selection of events, methods and properties.If you're looking for a professional tool that will simplify the tasks of monitoring and managing your network's ports, PRTG Network Monitor is your solution. Offering both a completely free, basic edition and expanded commercial editions, PRTG Network Monitor is the right choice for all your network monitoring & analysis needs.Read more about PRTG's port sniffer. Illustration of how the port sniffer works "I am an avid supporter of PRTG and I would like to congratulate you on this most excellent product which really works very well and is very easy to use. You have identified a gap in the market for easy "MRTG"-style traffic management, and I have to say without your product I would certainly be lost. I stumbled upon PRTG in Google whilst again looking for an easy to use "MRTG"-style traffic graphing and immediately bought it. I have also encouraged my partners to purchase the application. My business is an Internet Service Provider and we also have a Wireless Internet Service Provider Division. I use PRTG to monitor all my critical links." Eugene van der Merwe, www.snowball.co.za"I really think that you guys have made a damn good program here, and I have never regretted buying it from you. For the past 3 years I have been using MRTG and ever since I started using it I have been searching for a program like this one. So 3 words for your team, DAMN GOOD JOB.", Jeppe Jessen, www.dns-service.dkPRTGNetwork Monitoring Software -

Red Alert You can create Node-Red web pages to monitor network conditions like hard drive space, network, and CPU loads. Node-Red can also be used to read and set Pi GPIO pins using SNMP. There are some great full featured networking packages like Nagios [1] and MRTG [2] that can be installed on the Raspberry Pi. If, however, you are looking for something smaller to play with, then Node-Red might be the answer. Node-Red is a visual programming environment that allows you to create applications by dragging and dropping blocks (nodes) on the screen. Logic flows are then created by connecting wires between the different blocks (nodes). Node-Red also comes with Web Dashboards that allows you to view data or control the app from your smart phone.In this article we will look at creating some smart phone dashboards that will monitor PCs and control Pi GPIO devices (Figure 1).
