Efficient Linux Server Monitoring

Linux server monitoring is an important aspect of the entire network performance monitoring and IT operations management process if your network has Linux servers. Basic troubleshooting of Linux servers can be easily achieved using simple built-in commands, especially for monitoring CPU, memory, and processes. But that doesn't quite do the job of effective Linux server monitoring tools. A full-fledged, multi-faceted, all-in-one Linux server management tool is needed for a holistic monitoring approach. This is especially true for businesses and enterprises that want to ensure the best business-continuity experience for their organization and end users.

Advantages of Linux servers over Windows servers:

Monitoring Linux servers is more advantageous because:

  • The total cost of owning a Linux server is lower compared to a Windows server.
  • Linux servers have lower licensing fees, software and hardware costs, maintenance expenses, and system support service and administrative costs.
  • Linux is a more secure kernel, so Linux-based operating systems are secure and suitable for servers.

Challenges of Linux server monitor

Here are some of the challenges of Linux server monitoring:

  • Overused or underused resources go unmonitored until a command is run to identify the resource usage.
  • Doing root cause analysis is like finding a needle in a haystack.
  • Most monitoring vendors design tools without Linux support.

OpManager is an all-in-one IT monitoring solution that provides unmatched real-time Linux server management and its monitoring capabilities for various servers, including those running Linux. Important Linux server performance metrics like CPU, memory, and health can be monitored using OpManager. Multi-level thresholds can be set up for the important Linux server monitoring metrics to ensure they are constantly or periodically monitored.

To carry out Linux server performance monitoring, make sure either Telnet or SSH is enabled on the server. OpManager supports all major Linux distributions, such as Red Hat Enterprise, SUSE, Ubuntu, Fedora, Debian, and CentOS.

CLI-based Linux server performance monitor and host monitoring in OpManager

Linux Server Monitoring - ManageEngine OpManager  

If a device has both SNMP and CLI credentials associated with it, OpManager's Linux server management software will first try to fetch the processes via CLI and then via SNMP. OpManager can perform Linux server monitoring of any server type that responds to the commands used by OpManager, for fetching data from the end device. A Linux server monitoring dashboard is also available in the OpManager UI.

All the Linux server templates in OpManager's Linux based server monitoring have the resource monitors preconfigured. Admins can select CLI monitors and associate them with the required devices. An action can be chosen from the list of resource monitors. Select the CPU, Memory, and Disk Utilization monitors.

Process monitoring using CLI protocol in OpManager

Linux Server Monitoring Software - ManageEngine OpManager  

Monitoring Linux server processes using CLI is one of the effective ways to collect data for monitoring. OpManager acts as a Linux process monitor, using both SNMP and CLI to fetch data on critical processes running on Linux, Solaris, Unix, HP-UX, and IBM AIX.

Linux device templates in OpManager

Linux Server Monitoring Tools - ManageEngine OpManager  

OpManager offers Linux-specific device templates. But first, let’s look at what device templates are. Device templates in OpManager are used to automatically associate a device model's details with a new or existing device in the network. A device template is pre-populated with device-related details such as device type, vendor, system description, and the object identifiers provided by the vendors' MIBs. The primary use of device templates in OpManager is to simplify initial Linux network management configurations for the end-user as pre-configured thresholds are applied automatically saving them some time. A secondary value-add would be that device details can be viewed in OpManager.
