Firewalls are the quintessence of providing comprehensive security for your network infrastructure. They safeguard anything from mission-critical business processes to confidential customer data. Unforeseen interruptions in the firewall could mean big bucks, or worse. So to guarantee the safety of your network, it is important that you continuously monitor your firewalls to ensure that they run reliably and are up to date. SonicWall offers several firewalls to cover your security needs.
SonicWall Monitoring With PRTG Network Monitor
PRTG Network Monitor provides several ways to monitor your SonicWall equipment. Before you start monitoring, it is important to note that the Simple Network Management Protocol (SNMP) must be enabled on your SonicWall device via the SonicWall Management GUI. Please follow these steps to enable SNMP.
Tip: If you would like to learn more about SNMP, check out our Knowledge Base article!
For SonicWall Monitoring - out of the box - PRTG has the SNMP SonicWall System Health sensor to help you keep an eye on the overall health of your firewall, including CPU usage, memory usage, and connection cache usage by using SNMP.
The PRTG SonicWall Monitoring Sensor provides important statistics at a glance
In addition, PRTG has a built-in SNMP SonicWall VPN Traffic sensor that gives you a good overview of the Internet Protocol Security (IPsec) Virtual Private Network (VPN) traffic on your SonicWall device such as the number of encrypted and decrypted packets per second and ingoing/outgoing fragmented packets per second.

You can add these sensors to a SonicWall device manually or via the PRTG Auto-Discovery and the SonicWall device template. Once you have added the sensors, we recommend that you add appropriate limits to ensure that you will be informed when the memory usage is too high, when the CPU usage is higher than expected, or when you suddenly have more connections than your device can handle. the best SonicWall monitoring results possible. Follow these steps to set up limits:
- On the sensor’s Overview tab, click the respective gear icon in the channels data table.
- Enable Limits.
3. Select a channel from the dropdown list at the top of the channel settings dialog.
4. Enter appropriate limits for each channel.
5. Click OK to save your changes.
For more information on setting channel limits, watch our video How to Set Channel Limits or visit the PRTG manual.
