SSH Monitoring:
PRTG keeps you in the know

Complex network infrastructures

Most corporate network infrastructures are not just limited to one single operating system or type of computer or server. Various versions of Windows Server and Client are used for many applications, as are Linux systems – even for IT infrastructures that are based mainly on Windows. The number of available web and file servers is astonishing. And most companies have at least one department that uses macOS.

Maintain an overview

As an administrator, it’s your job to keep an eye on what is going on in the company network. But with countless different tools to check in the event of a problem, things can get out of hand quickly. This is where the PRTG Network Monitor comes in. With our professional monitoring solution, you will not only be securing the operation of Windows systems, but can also take advantage of a variety of monitoring protocols to monitor Linux distributions and macOS systems. Along with the Simple Network Management Protocol (SNMP), Secure Shell (SSH) is an especially good choice for such monitoring.

iSNMP stands for Simple Network Monitoring Protocol. Its usefulness in network administration comes from the fact that it allows information to be collected about network-connected devices in a standardized way across a large variety of hardware and software types. SNMP is a protocol for management information transfer in networks, for use in LANs especially, depending on the chosen version.

Prevent downtime

PRTG uses SSH monitoring to collect performance data and system information from computers and servers that can be accessed via Secure Shell. As a result, PRTG lets you check the availability, response times, and other system data of your Unix-based systems. This information can then be used to quickly fix network malfunctions and protocol errors and increase the availability of applications and services on Linux and macOS systems. SSH is also a good choice for monitoring SAN (storage area network) systems. And to do so, you won’t need to install any additional software on your target systems.

Security is guaranteed

The SSH protocol transmits monitoring data over an encrypted connection, thereby ensuring your systems always remain secure. The SSH authentication can be done with a password or OpenSSH-RSA private key - with PRTG, both are possible.

PRTG lets everyone work with the utmost security.

Immediately see if your server is available

How SSH monitoring with PRTG works

Collecting data with SSH

By using Secure Shell (SSH) for your monitoring, you can gather the system information and performance data of servers connected to Linux and Unix distributions, macOS computers, and SANs. PRTG automatically connects to the target server and establishes the SSH connection between the two computers. You therefore won’t have to install any additional software on the target system.

Authentication

To monitor via SSH, PRTG requires login information for the target system, ideally with root access. PRTG allows for authentication using a password or an OpenSSH-RSA private key. Simply enter your login details into PRTG in the device settings. With PRTG, you can also use these details to access more than just individual devices, and have the information transmitted automatically so it does not have to be re-entered each time a new device is added. Find out more about authentication in our knowledge base.

Several SSH sensors at your disposal

If you used an IP address or DNS name to add your end device to PRTG, then you have the choice of several native SSH sensors for ensuring the smooth functioning of your network. PRTG comes with default sensors for monitoring average loads, available inodes, and hard drive capacity. You can also monitor the ability of a Linux or macOS computer to connect to another device, or query FTP servers by way of SFTP (FTP over SSH). Your SSH monitoring is made complete by PRTG’s built-in SAN sensors, which let you keep a constant eye on the logical and physical disks, system status, and storage information of your SANs!

 

iAn IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network. IP addresses are binary numbers but are typically expressed in decimal form (IPv4) or hexadecimal form (IPv6) to make reading and using them easier for humans. Read more ...

Create your own sensors

With PRTG, if you’re unable to find the required sensors for your SSH monitoring, you can simply write your own. To do so, create a script that returns a numerical value, XML, or JSON from the target device, and monitor the result with an SSH script sensor. PRTG can be customized to meet all your needs.

SSH data gathered by PRTG

 

 

i Ping is a command-line utility, available on virtually any operating system with network connectivity, that acts as a test to see if a networked device is reachable. The ping command sends a request over the network to a specific device. A successful ping results in a response from the computer that was pinged back to the originating computer. Read more ...

 

  • Server availability and response times
  • Average server load
  • Available memory (Meminfo)
  • Available disk space
  • Number of available inodes
  • Connectivity to other devices via remote Ping
  • Custom values via user-defined scripts
  • Response time of an FTP server in a Linux/Unix environment (SFTP)


PRTG also uses SSH to gather the following data from an SAN:

  • Status of an SAN enclosure, including the statuses of power supplies and controllers
  • Status of logical and physical disks, including I/O operations and the amount of data transferred per second
  • System status of an SAN, including temperature and power supply data

4 good reasons to choose PRTG as your SSH monitoring tool

Increased availability

Servers, services, and applications suffer fewer disruptions and react faster, which in turn boosts their availability.

Quick troubleshooting

Network failures and protocol errors are detected promptly and can therefore be remedied at once – not just on Windows operating systems, but also Linux-based ones!

Secure data traffic

With SSH monitoring, you can be sure the connections required for your monitoring are secure thanks to SSH authentication and encryption. As a result, you will minimize security risks.
