Monitor - 40 monitoring Network & Server Tools
Today I would like to merge old articles and indicate other Monitor tools:
- PRTG monitors is freeware using up100 sensors.
https://www.it.paessler.com/
From my experience it work fine with all devices such switches, Firewall, client, Server, Hypervisors, SNMP devices and so on.
An interesting tips is installing different PRTG istances on different servers (bypassing 100 sensor free limits) using PRTG client software that permit you to have single management console, without having necessity to purchase license. - SolarWinds All Free Network/System/Security/DB/clients monitoring tools

https://www.10-strike.com/network-diagram/ - Multi Router Traffic Grapher (MRTG): Open source Round Robin Database (RRD)–based network monitoring and graphing tool used to show current and historical information about network devices, specifically router and switch interface statistics. This tool is freely available from oss.oetiker.ch/mrtg/index.en.html.
- WhatsUp Gold: Ipswith’s network-device monitoring tool, which is capable of discovering network devices, tracking system health, and receiving Simple Network Management Protocol (SNMP) trap and Syslog data. Ipswitch provides a 30-day evaluation of the product, whose price starts around $1,500 for the ability to manage 25 devices. Check out their website at www.whatsupgold.com.
- Cacti: Open source RRD–based network monitoring and graphing tool. If you have used MRTG but wanted something a little flashier or geared towards other types of devices, then Cacti may be for you. Cacti makesit easier to add devices such as servers to your monitored devices list. As with MRTG, this tool is freely available, and you can find it for downloadon their website, www.cacti.net.
- Xymon Monitor (formerly Hobbit Monitor): Open source–device monitoring and alerting tool, as shown in Figure 2-4, that displays current status information for network devices. Like Cacti and MRTG, Xymon is capable of gathering a wide range of information about your devices and offers historical information on those devices in the form of RRD–based charts. One difference with Xymon lies in its ability to send out alerts to configured users in the event that certain conditions have been met, such as a device has gone offline for more than 5 minutes or free disk space on a server has dropped below 100 MB. You will find Xymon on itsSourceforge page at xymon.sourceforge.net.
- NetFlow: A Cisco Internetwork Operating System (IOS) component that collects and measures data as it flows through switch and router interfaces. While NetFlow on a switch or router collects data, it does not provide any of the analytical functions. For analytics, you will require a NetFlow collector.
- Cisco NetFlow Collection Engine: Cisco’s NetFlow gathering and analysis tool that collects NetFlow data from network devices and allows for centralized analysis of the data. This data can be analyzed across the network to ensure that application data is passing over the network in a manner that is appropriate to the application. For example, you could use this tool to ensure that a business-critical accounting system is not being impacted by users watching YouTube videos. You can get more information about the NetFlow Collector Engine from www.cisco.com/en/US/products/sw/netmgtsw/ps1964/index.html, but this product comes with a price tag in excess of $16,000.
