Here is a list of Best Free SNMP Manager Software for Windows. SNMP stands for Simple Network Management Protocol which governs the management of connected IP devices within a computer network. Using any of these freeware, you can manage and monitor servers, computers, switches, virtual systems, printers, and other network devices within an enterprise. These SNMP monitoring software help you monitor connected devices within a network in terms of connectivity, availability, performance, bandwidth and traffic on servers, PCs, switches, etc., and more.
To configure devices, you need to enter a single or a range of IP addresses. Or, you can initiate an automatic scan for device discovery. Once added, you can assign different sensors i.e. monitoring topics for an individual device. MIB files can also be loaded in these SNMP manager software to have a watch over a particular object. You can add watch items called ping, trap, and variable.
The analysis data is shown in the form of a graph in real-time. You can customize update time interval to monitor this data. Also, the past analyzed data within a time range can be viewed. In some of these SNMP manager software, you can export the analyzed data as an HTML report.
Overall, these free SNMP manager for Windows are pretty easy to setup and use. But, if you have a tough time figuring any of them out, help center feature and demo videos are provided for you.

PRTG Network Monitor
PRTG Network Monitor is an advanced SNMP manager software for Windows. Although it’s a 30-day trial version and for first 30 days, you have no restrictions on using all of its features. But after that, you can use it for free for 100 sensors (monitoring topics) only. PRTG Network Monitor works in your default web browser.
Firstly, using PRTG Administrative Tool, you can configure settings like web server (HTTP port number, IP address for PRTG web server, etc.), probe settings (name of probe, reconnect time, etc.), etc. In Administrator tab, you can set up your login name and password to use this software.

To monitor a device, you need to select the device and add sensors. On clicking Add Sensors button, it shows categories of sensors which you can add. Select what you want to monitor (bandwidth, uptime, speed, performance, network infrastructure, etc.), target system type (Windows, File Server, Cloud Service, Database, Email Server, etc.), and technology used (SNMP, Ping, HTTP, SSH, etc.). As you select categories, it displays all available sensors. Some of the sensor types are monitor DNS server, connectivity, bandwidth and traffic on servers, PCs, switches, etc., web server using HTTP, FTP server, Google Drive, SMTP, etc. These are just a few popular ones. It provides a wide range of sensors to monitor a network. As mentioned above, you can choose up to 100 sensors in free edition.
For the analysis purpose, it shows information related to a particular monitoring element (sensor), like uptime, downtime, sensor type, dependency, coverage, last scan, last up, last down, interval, etc. Apart from this, it displays sensor specific data. For example, for PING, it displays packet loss, Ping time, minimum value, maximum value, etc. You can monitor Live Data as well as view statistics from past 2 days, 30 days, or 365 days. From the Historic Data tab, you can export statistics report related to a specific monitoring topic in CSV, HTML, and XML formats. For this, you can select a time span. In the report, you get information in graphical and tabular forms. Using the Alarms menu, you can view sensors with errors, warnings, and unusual status.

Spiceworks Network Monitor
Spiceworks Network Monitor is a free SNMP manager for Windows. It is another good software to monitor networking devices and get real-time status and alerts regarding the same. It operates in a web browser. On the Dashboard, you can view the number of servers, switches, and sensors which are currently being monitored.
Let’s talk about its main modules and functionalities. The main screen is divided into three sections which are used to add servers, devices, and switches. You can add a Windows server using IP address or hostname, device name, username (domain name), and password. As you do that, in the Server Watchlist, you will be able to see real-time data including CPU usage (in percentage), Disk rate (KB/s), Network rate, and Memory usage. Click on the added server name and you will see a detailed report in the form of a graph. The statistics are shown in individual graphs for CPU Utilization, CPU Queue Length, Memory Utilization, Memory Page Faults, Disk Used Space, Disk I/O, Network I/O, Network Packets, and Network Packet Loss. The running processes (with memory and % CPU usage) and services (with state) can be accessed from the right panel. On hovering mouse over a process, it shows the process ID, name, and user; while for services, it shows name and description. For your convenience, it lets you drag a process and services to monitor. It provides a Stop Process button too, but it didn’t work fine during my testing.
To add devices, go to Online Watchlist and click on Add Device. Now, enter IP/Hostname, Username (optional), and select check type (Ping, HTTP, HTTPS, SSH, SIP). In advanced settings, you can customize settings including timeout (ms) and poll frequency (30s, 5m, 15m). The device will be added and you will be able to monitor its Network Latency graph on clicking the device name. In this Online Watchlist section, you can view all added devices with their statuses (online or offline).
In the Networking Watchlist, you can add a switch with IP/Hostname and SNMP Community string. This list monitors packets per sec, packet loss, I/O rate, etc.
You can enable alerts for particular condition like CPU is spiking, network bandwidth is spiking, disk is overloaded, etc. The alerts are displayed on the dashboard. This will help you manage devices according to the alert generated. An Actions option is provided to let you customize alert settings (dashboard alerts and email alerts) and credentials used to connect a device.
Overall, Spiceworks Network Monitor is quite user-friendly. It is another one of the best SNP monitoring software. Details about a monitoring device like Manufacturer, Processor, RAM, Disk Capacity, Last Reboot, etc. can also be viewed in it. Home Page Download Page

PowerSNMP Free Manager
PowerSNMP Free Manager is a basic SNMP manager software for Windows. You can add network devices and SNMP agents by going to Discover menu. You can discover devices within a network using a range of IP address, broadcast IP address, or manually add an individual IP address. For an SNMP agent, you need to enter details of the device which include IP address, port number, SNMP version, and community. It will then monitor the values of added SNMP Agent variables, monitor traps, and pings network hosts.
On its main interface, you can find discover device (added devices), watch item (added watch items), and MIB (loaded MIB file) windows. In the MIB window, you can see objects in the hierarchal form. On clicking an object, information like OID, status, access, type, module, etc. are shown. In a below panel, you can see traps and log information.
PowerSNMP Free Manager lets you add three types of watch on an agent named Variable Watch (variable ID and value), Trap Watch (generic trap, specific trap, etc.), and Ping Watch (response time). You can add these watch items by going to Watch menu, or drag and drop respective MIB file from right panel to Watch Item window.
You can configure the update interval time (seconds) and timeout (ms) for individual SNMP Agent. It lets you enable email notification alerts if you want.
