SNMP Is used in almost Every networking device and Computer/Server in your IT Infrastructure – We've gone through many other monitoring protocols, including WMI Monitoring tools and IP Monitoring tools and software in the past, but this article will highlight SNMP Scanning Software and tools for your network.
What is SNMP?
SNMP (Simple Network Management Protocol) is a scanning technology that is used as a Network Discovery tool and data gatherer. Many network scanning tools use SNMP as a means to collect valuable information about the current state of devices on the immediate network.
Things like printers, computers, servers, and even some versions of software are detectable from SNMP capable applications, so it is very useful and effective in administering and managing your company’s resources. There are other benefits to it as well, such as finding out serial numbers of your hardware, and even warranty stats and toner and ink levels in printers around the office.
We want to look at some of the products that you can use to try and get your network in tip top shape, with no unknown quantities being in the mix. A known quantity on a network is far better than anything that will take you by surprise much later, such as a rogue device like a small computer or network device.
8 Best SNMP Scanner Tools and Software:
1. SolarWinds SNMP Scanner
SolarWinds SNMP Scanner is a mapping tool that lets you discover and monitor everything on your network. It helps you discover network devices by performing SNMP sweeps and discovers and collects many detailed configuration reports about the entities on the network. Because of the way it scans and collects, it gives you the ability to map and create an overview of the current state of the network.
One of the great benefits of using this application is that it lets you monitor faults on the network, the availability of devices as well as the overall performance of the network. Performance metrics and MIBS data ensures that you have an accurate picture of the current state of network health and speed.
