3 SNMP sensors for getting started
  

 

SNMP Traffic Sensor

The SNMP Traffic Sensor shows you the amount of data that runs through your network or a specific network device. You’ll therefore be able to immediately see if a server is heavily strained or overloaded.

 

 

SNMP Hardware Status Sensor

This sensor comes in handy for determining whether one of your server’s hardware components is running or not. You can also create special sensors that monitor components such as CPU, memory, or hard disks separately.



 

SNMP Custom Sensor

The SNMP Custom Sensor is customizable. In search of a way to monitor your virtual servers, mail servers, or file servers? PRTG comes with preconfigured sensors for each and every one.

iWhat is a sensor?

In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Why SNMP-compatible servers
are a good idea for your IT infrastructure

The standard

SNMP (Simple Network Management Protocol) has been the standard protocol for network management for many years now. Reliable and robust, this protocol can be used to manage and monitor network devices such as servers, computers, routers, and switches. Pretty much every device – including those from the biggest manufacturers – supports SNMP. For more information, visit our page on SNMP. PRTG comes with preconfigured monitoring sensors for the servers of all the biggest manufacturers.

 

Uniformity

System administrators are often responsible for managing extremely complex networks made up of devices from many different manufacturers. These networks also use a number of different servers, including mail servers, database servers, and more. When monitoring, it therefore makes sense to focus on one central protocol. With PRTG, you can also use other protocols for your monitoring such as WMI for Windows servers, NetFlow, and packet sniffing. 

 

Monitoring

PRTG is a centralized Windows monitoring tool. It comes with a built-in dashboard that lets you keep a constant eye on the status of your servers as well as your entire network. If something goes wrong, you’ll automatically receive an alert – before the problem gets out of hand and your coworkers or customers begin to notice. PRTG lets you take action at once. You can also try or use our software free of charge. The free version of PRTG comes with 100 sensors and all the software’s features. If this is all you need, then you can take advantage of network monitoring without having to spend a penny.

 

Monitor your servers via SNMP

Configuring SNMP on your Windows servers: How it works

No two servers or Windows systems are operated in the same way. Nevertheless, we’d like to
provide you with some simple instructions for configuring SNMP. For more detailed instructions
(including screenshots), please see our blog article, in which we go over the various versions of
Windows and SNMP.

 

Step 1:

Determine whether your
server is compatible with SNMP

In general, Windows servers are compatible with SNMP. For other servers or devices, have a look in their manuals to find out if you can monitor them using SNMP. Product datasheets and manufacturer websites are also a good bet for finding information on whether a server is SNMP-compatible – and how to configure it.

Step 2:

Enable SNMP
in your settings

Open “Programs and Features” in your Windows settings. Here you’ll find the SNMP function. Click the box to enable SNMP. For some Windows servers, the SNMP service must be installed anew.

Step 3:

Check the
other settings

In the “Agent” category, check to make sure all the SNMP services are available. In “Security,” check the password, encryption, and port numbers. You can then create a sensor in PRTG.

Software for SNMP server monitoring:
6 advantages of PRTG

 

Quick troubleshooting

Centralized monitoring

Many companies make do with whatever monitoring they can muster. They use a variety of small tools – usually free tools or open-source software – which can take a great deal of time and effort to set up and configure. With PRTG, you get one centralized tool that monitors your network devices, data packets, applications, and much more.

Identify shortages

Easy-to-read dashboard

With PRTG, all your monitoring data is neatly displayed on one central dashboard. It only takes a quick glance to see if everything is OK. You can also consult the dashboard from your smartphone or tablet. As a result, you’ll enjoy peace of mind and can confidently go about your other tasks. PRTG runs continually in the background, 24 hours per day, 7 days a week.

Promptly diagnose capacity

Automatic alarm

PRTG comes with an automated notification system. This alarm is included free of charge. It notifies you immediately in the event that a sensor picks up on a server error via SNMP. You get to choose the servers and devices that trigger alerts, as well as the means by which these alerts are sent (email, SMS, push notification, etc.).

Reduce costs

Improved IT security

PRTG monitors your servers, firewalls, routers, and ports in real time to root out unusual activity. It is therefore a vital part of your security structure. Open ports, in particular, can serve as loopholes for viruses and attacks.

Increase morale
