In the ever-evolving world of networks and network devices, Linux is slowly becoming the operating system of choice for many businesses running complex IT infrastructures. There are multiple ways to monitor a Linux device, but a secure and solid way is using SSH, also known as Secure Shell or Secure Socket Shell.
The SSH network protocol allows network services to be operated securely over an unsecured network. The SSH protocol transmits data over a secure encrypted connection, so most Linux-based devices are SSH clients due to the enhanced security. Generally ManageEngine OpManager uses SNMP and WMI protocols to monitor various devices and interfaces.
CLI supports SSH and Telnet protocols. OpManager monitors Linux devices using SSH, and is used to interact with the devices directly. One of the prominent features of OpManager is to monitor Linux devices using SSH.
The SSH protocol transmits data over an encrypted connection, so your systems remain secure. To monitor Linux servers using OpManager's SSH monitoring tool, OpManager should be installed on the server, and will require authentication. For authentication, administrators must provide a combination of username and password, or generate and authenticate using an SSH key.
Beyond keeping an eye on what is happening on your Linux devices, other benefits gained from utilizing the SSH monitoring tool include:
SSH establishes a secure, encrypted tunnel for communication between network management software and devices. It allows network admins to keep track of network performance, and diagnose and rectify any network faults.
With the SSH monitoring tool, these performance metrics can be monitored:
OpManager is a comprehensive SSH management tool that has helped millions of network admins all across the world. Now, with SSH monitoring tool for Linux, you can securely monitor the health, performance and availability of Linux servers with ease.
OpManager provides a graphical view of performance metrics, such as processor time, memory, and disk space consumed, to monitor and measure server performance in real time, ensuring that your network performance is at its peak. The monitored data is collected and stored for future tracking and analyzing purposes, and for creating monthly and yearly performance reports. This helps you predict potential network outages and proactively troubleshooting them.
OpManager's SSH monitor allows you to monitor critical processes running on Linux devices using SSH protocol. SSH performance monitoring guarantees the optimal performance of your devices by identifying unnatural load in system resources, and helps you accurately pinpoint the processes and services that utilize an unhealthy amount of resources.
Using Process templates, you can manage, monitor, and set thresholds over multiple devices from a single server. When a particular process violates the set threshold, you can even remotely stop the process to avoid resource drainage.
Scripts are often used to automate simple, repeatable tasks. But manually monitoring the outputs of these scripts can be a tedious task. Using OpManager's Custom script monitoring, you can manage these scripts and add new scripts from a single workstation. With OpManager's Script monitoring feature, you can set thresholds for the script's output, and get alerted via SMS or an email. You can also automate a workflow based on the script's output.
OpManager’s script monitoring supports PowerShell, VBScript, and the Linux shell, Perl, and Python scripts. This enables you to manage various monitoring scripts with ease.
Thanks to the performance statistics displayed in reports and dashboards, network administrators can easily monitor, detect, and resolve network issues monitored using SSH.This intuitive visual data can help you identify potential problems. With over 100 built-in reporting profiles, all the data monitored using SSH is easier to view, making troubleshooting easier.
