The advantages of SNMP Monitoring with PRTG


SNMP-Sensoren

SNMP sensors

PRTG comes with several preconfigured SNMP sensors. Among these is a series of sensors developed especially for device manufacturers such as Cisco, HP, Dell, and Synology. Below you will find a selection of our "best-of" sensors. Whether servers, routers, or switches: with PRTG, you get a professional SNMP network monitoring software and a comprehensive view of your network.

Integrierte Alarmfunktionen

Built-in alarm features

Our SNMP monitoring software is equipped with a built-in alarm feature. You're free to set the threshold values and alert method (email, SMS, or a free push notification to your smartphone) any way you please. PRTG includes a customizable notification system which you can define according to your own personal needs.

Unterstützung

Support

SNMP versions (SNMP V1, V2c, or V3) can vary from device to device. Should you encounter issues while setting up your SNMP tools for Windows, the Paessler Support Team will be happy to offer you their expert advice and assistance. In general, our support team answers inquiries within 24 hours. With SNMP tools like the SNMP Tester, you can detect and debug problems. Simply send your log files to our support team for analysis.

Auto-Discovery

Auto Discovery

PRTG's Auto Discovery facilitates your search. With this feature, all of the available devices in your network which are switched on for SNMP monitoring are checked, and suitable sensors are created, automatically. Your initial monitoring will thus be set up in the blink of an eye! You can then get down to its fine-tuning.

Berichte

Reports

Reports are also included in the free SNMP monitoring software. Among other things, they feature clear and comprehensible charts. One of the times these reports can come in handy is when your hardware is under heavy strain and you need to convince your higher-ups to provide you with the funds for an upgrade.

Use PRTG as an SNMP
Trap Receiver

 

All in one, no extra cost: that is our philosophy. With PRTG, the full range of features is included. There are no hidden fees or additional upgrades to pay for. This is also true if you wish to use your monitoring for SNMP traps. Using PRTG as a trap receiver is simple! For we've created an appropriate sensor - which is also available in the free version (100 sensors) - to help you get started.

SNMP traps: With SNMP monitoring, monitoring software usually sends small data packets to target devices in order to request various information from them. This in turn triggers response packets from the monitored devices for SNMP manager. The upside of SNMP traps is that devices automatically send messages to the SNMP monitoring software in the event of crucial incidents, without first being requested to do so.

5 advantages
of SNMP Monitoring

 

 

 

PRTG lets you monitor your network via SNMP. NetFlow and Packet Sniffing are used for the in-depth monitoring of data traffic, while SNMP provides for a comprehensive overview of the performance of your network. SNMP boasts the following five advantages:

Super reliability

In general, network monitoring with SNMP is extremely reliable. PRTG offers many sensors adapted to the various versions (SNMP V1, SNMP V2c, and SNMP V3) and different manufacturers.

Minimal bandwidth usage

SNMP monitoring requires a minimum load of bandwidth. As an professional system administrator, the SNMP bandwidth monitor gives you the overview you need and the control that goes with it, without putting too much strain on your network and SNMP traps.

Low CPU load

Like the bandwidth, the processor is barely affected. The CPU load of SNMP V1 and V2c is nearly imperceptible, even with broader monitoring including several thousand sensors.

Compatibility

Almost all of the major device manufacturers (including Cisco, Dell, and HP) offer the Simple Network Management Protocol. For many devices, it is the only protocol used to read values.

Platform-independence

SNMP is a platform-independent standard. Activate the SNMP service in your Windows computer or configure the SNMP daemon in Linux. SNMP is also available for Mac OS. You can therefore incorporate all your computers into the holistic SNMP management software PRTG.

Our recommendations:
THE TOP-5 PRTG sensors for your SNMP Monitoring

 

 

 

Use the following five SNMP sensors to monitor the most important features on each of your devices. More sensors can be found in our PRTG sensor list. There are dozens of SNMP sensors, and over 200 in all!

  • SNMP CPU Load Sensor: PRTG's SNMP CPU Load Sensor shows you the extent to which your processors are being utilized. The load is displayed as a percentage in a typical PRTG tachometer.
  • SNMP Disk Free Sensor: The SNMP Disk Free Sensor shows you how much hard disk space is available. This value is displayed as a percentage and in bytes.
  • SNMP Memory Sensor: The SNMP Memory Sensor shows you how much memory is left. This sensor allows you to make plans to upgrade your hardware, if necessary.
  • SNMP Traffic Sensor: With the SNMP Traffic Sensor, you get a constant overview of the amount of data traffic flowing through a device's ports. Should the load begin to increase at a critical rate, you'll be notified quickly and in plenty of time.
  • SNMP Hardware Status Sensor: The SNMP Hardware Status Sensor allows you to keep a constant eye on your hardware. You will see if your devices are running and be notified in the event of a crash.

3 steps to SNMP monitoring
This is how easy you configure PRTG!

 

Höhere Zuverlässigkeit mit PRTG

Step 1

Check to make sure your devices support SNMP. This should be the case at your company, for SNMP has been a standard for several years for manufacturers such as Cisco, Juniper, HP, and Dell. In this step, PRTG also verifies which SNMP version is supported and discovers automatically all the respective devices in your network.

Schnelle Übersicht in PRTG

Step 2

Turn on SNMP in the device. There is often a management program or configuration page for this purpose. For many devices, the default SNMP setting is “off.” If there is a firewall between the devices and the PRTG probe, then configure the firewall accordingly. Activate SNMP port 161 and open all outgoing ports greater than 1023 for SNMP on the PRTG side of the firewall.

Einfache Einrichtung in PRTG

Step 3

Create appropriate sensors for the devices in PRTG. The sensor settings must be compatible with the device’s version of SNMP so the respective data can be read.

SNMP V1
vs. SNMP V2 vs. SNMP V3

 

 

 

Due to the large number of devices (routers, switches, servers, etc.), several manufacturers were forced to define a common standard for monitoring the functionality of devices and networks.

SNMP V1: The first SNMP version was defined in 1988. It is still in widespread use today, mainly because it is much easier to use than the other versions. However, this version does not come with encryption. It is therefore recommended that SNMP V1 only be used in private LANs which are not connected to the Internet.

SNMP V2c: When people speak of version 2, they usually mean SNMP V2c. This version, however, also lacks encryption. One feature of SNMP V2c is that it supports 64-bit counters, whereas SNMP V1 uses only 32-bit. 

SNMP V3: The third and most current version of SNMP also supports encryption and significantly increases the security of SNMP monitoring. Nevertheless, setting up SNMP V3 is complex and elaborate in comparison to its predecessors. To date, it has not been successfully implemented in intranets.

Quote Tech Support

“Hey Luciano, what would you tell administrators looking to set up SNMP monitoring with PRTG?”

“With PRTG, you not only get the many standard sensors which exist for SNMP monitoring, but also the ability to monitor devices even without having a native sensor for them. You can thus monitor practically any SNMP-compatible device! First of all, obtain the relevant MIB file containing a definition of all available OIDs from the manufacturer of your hardware. Then use the MIB importer to make the MIBs available to PRTG, and create an SNMP library sensor. Finally, select the properties of the target device you’d like to monitor, and within no time at all you’ll have the data you need!”

Over 95% of our customers recommend PRTG

Paessler AG submitted an extensive survey to interview more than 600 IT departments worldwide who use PRTG. The goal of this survey was to optimize and fine-tune our Network Monitoring Software to better meet the needs of administrators.

One survey result: more than 95% of the participants would recommend PRTG - or have already done so.

SNMP Alternatives:
WMI, Netflow, Packet Sniffing

 

WMI

Windows Management Instrumentation (WMI) is a standard developed by Microsoft. Depending on the size of your network, WMI can lead to load problems. Here too, PRTG comes to the rescue with its specific sensors. Find out more on the page on WMI Monitoring.

 

NetFlow

Netflow and IPFIX are protocols which are used mainly in Cisco devices. But other protocols, such as sFlow and jFlow, are also suitable for bandwidth monitoring. Find out more on our Netflow Monitoring topic page.

 

 

Packet Sniffing

Monitoring via packet sniffing provides you with detailed insight into your data packets. This is convenient, namely, when you'd like to take a closer look at why data traffic problems sometimes occur in your network. Find out more on the page on Packet Sniffing Monitoring.
