How to monitor Linux
performance with PRTG

PRTG Network Monitor comes with special sensors for Linux and Unix. PRTG is agentless monitoring software, which means there’s nothing to install or modify on the target machine.

SSH and SNMP protocols are used to provide detailed information on Linux performance. For example, you can keep a constant eye on the amount of memory used by all your devices and be alerted if one of your predefined values is exceeded. Memory monitoring is especially important if you use application and terminal servers.

PRTG also monitors the bandwidth of your Linux systems and can sort bandwidth usage by port, user, and application. As a result, you can quickly identify unusual or suspicious traffic.
