1. SolarWinds Network Performance Monitor (NPM) – FREE TRIAL

SolarWinds Network Performance Monitor (NPM) is a tool that makes the life of a network administrator much easier. It is able to monitor and alert you about any issues or problems on your network, with very little delay. You are able to monitor many different objects and sources such as applications, services, VPN tunnels, and much more.

It features Network Availability Monitoring, Critical Path Visualization, Intelligent Mapping, Performance Analysis and Advanced Alerting. This means that you can configure it and set it up to match your requirements. For instance, you can configure it as a Cisco Network Monitoring Tool.

This will give you the ability to monitor and analyze faults, availability and the performance of the Cisco device itself.

You can also use this application as a Cloud Server Monitor. Because of the remote nature of Cloud services and infrastructure it can be challenging to see if everything is running as it should be. For this reason, SolarWinds NPM allows you to Visualize the full network path of the device from the device itself all the way to its end point.

This is achieved with cloud monitoring by NetPath.

Other important features that this product offers includes Deep Packet inspection and analysis.

This allows you to gain greater knowledge about the current state of your network, as well as the state of traffic and data flow.

If you would like to try it out for yourself then you can find the details on how to download a free trial. All you need to do is give them your details and they will email you a link so that you can download and test it out for yourself.
