When you are working with Linux/Unix systems in your IT environment, it's a huge advantage to be able to gather all kinds of information regarding your systems in one place. SSH (Secure Shell) monitoring allows you to query data by executing specific commands after PRTG has logged in to your devices. A value that's always good to know is the free disk space.
With the SSH Disk Free sensor PRTG offers the perfect tool for monitoring the free space on disks of your Linux/Unix systems. It shows the following values:
Please note that this sensor type shows the disk space that is actually available for use: The returned values consist of the available disk space of the monitored volume, minus a reserve defined for this volume, for example, for redundancy purposes. The size of the reserved disk space can be defined with tune2fs. For more details please have a look at the Knowledge Base article on "Why do SSH Disk Free and SNMP Linux Disk Free show different values for my target Linux system?".
Do you want to keep an eye on the free disk space of your Linux/Unix systems without having to check every volume individually? Just add the SSH Disk Free sensor! For more information on this sensor type please have a look at its PRTG manual page.
