1. SolarWinds Network Performance Monitor – FREE TRIAL
The SolarWinds Network Performance Monitor is the most impressive real-time network monitoring tool on this list. The system starts its service life by scanning your network after installation and logging all of the devices that connect your network together. It creates a network inventory and then draws up a network topology map from that information.
The software inventory and network topology map are updated regularly with information derived from SNMP status checks, so the monitor immediately knows where any devices have been added, moved, or removed. This constant review of the infrastructure will also tell you whether unauthorized devices have been connected to the network.
Once the network inventory has been created, the Network Performance Monitoring tool starts its real-time tracking of all network issues. The attractive dashboard for the service includes easy-to-read color-coded graphics that assist in instant problem recognition.
You don’t have to sit and watch the screens of this tool in order to make sure that you don’t miss any problems emerging on the network because the service will notify you if your attention is needed. The system gets status notifications from agent software running on each network device and sends you a warning by email or SMS so you know to come back to the console.
Other features in this tool include performance analysis features, such as NetPath, which allows you to see the statuses of all connections on a route between any two given points on the network. The tool can reach across the Internet to monitor remote networks and it can also analyze the paths to Cloud-based services.
The Network Performance Monitor installs on Windows Server and SolarWinds offers it for a 30-day free trial.

3. Paessler PRTG – FREE TRIAL
Paessler PRTG is a collection of system monitors that cover networks, servers, and applications. Each customer receives the full package of monitors and customizes the tool by deciding which services to turn on. The price for the package depends on how many of those monitors, which are called “sensors,” you want to use.
PRTG is a pure monitoring service, which means that it doesn’t include any system management functions. It is an excellent monitoring system for networks, thanks to the core SNMP processes that underpin it. The initial call to all device agents brings back a batch of responses that identify all of the network devices connected to the system. PRTG collates a network inventory from this information and, as it continues its regular polling of devices, keeps that register of devices constantly updated.
The service creates instantly-drawn network topology maps from its network inventory. These maps are not drawn once and then stored but are generated every time you access the topology screen. That means that you never get a topology map that is out of date.
The SNMP network sensor in PRTG receives Trap messages that are sent out by device agents whenever they detect serious problems with the equipment that they monitor. These Trap messages get interpreted by PRTG into alerts on the screen of the system dashboard. The service will also forward these alerts to you by email or SMS. This means that you can get on with other tasks and assume that everything is working well with the network unless you receive a notification.
The Paessler PRTG system is available for a 30-day free trial that includes an unlimited number of sensors. So, you can try out all of the server and application monitoring tools as well as the network monitoring system for free for a month. The PRTG software installs on Windows Server.

ManageEngine OpManager combines network and server monitoring. The network supervision functions of this package are based on SNMP and include a network discovery service. This creates a constantly updated device registry that is refreshed by repeated SNMP device status checks.
The network topology map options in OpManager are very impressive. You can choose from a library of formats to get different views of your network infrastructure with live traffic and status data displayed on each. These topology maps are generated on demand so they show an up-to-date layout of the system.
The OpManager service processes SNMP Traps into alerts on the screens of the system console and also sends these out as notifications via email or SMS. This means that you can leave the OpManager service to monitor acceptable performance and you only need to pay attention when indicators signify that a problem is evolving.
The combination of network and server monitoring functions enables OpManager to provide excellent support for virtualizations. The system is also able to supervise Cloud-based virtual resources and the links to them plus remote networks over the Internet.
