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.
The Best SNMP Scanner Tools and Software
1. ManageEngine OpManager – FREE TRIAL
ManageEngine OpManager monitors networks and servers. The network monitoring part of the package is heavily reliant on SNMP for its functions.
Unique Feature
It helps to detect, isolate, and fix network problems easily.
Why do we recommend it?
We love the reports generated by this tool as it is insightful and provide all the key information required to make informed decisions about capacity planning and upgrades. Plus, it can also provide the status of all devices in real-time.
The OpManager network monitor starts its service life with an initial SNMP request poll. The OpManager system acts as the SNMP Manager and receives back MIBs from all device agents in response to its request broadcast. The service compiles all of the MIB information for a performance report page for each device.
The device report offers live performance statistics. The OpManager module repeatedly sends out status requests, refreshing the device performance screen with each cycle and compiling time-series graphs for selected metrics.
The initial performance screen gives the vital metrics for that device and you can select which pieces of information appear on that screen. However, a back screen provides all data returned in the MIB.
The OpManager dashboard also displays status alerts, which are derived from any Trap messages sent back by agents. The settings of OpManager allow you to specify an email account or mobile number to which the service can forward alerts as email or SMS notifications.
Other features in the OpManager package are server monitoring, Active directory monitoring, web and email server monitoring, VLAN monitoring, and virtualization monitoring. All of the services and software that the system monitors are measured by performance thresholds that will generate alerts if crossed.
