This tutorial intends to introduce the Best Linux System Monitoring GUI Tools. Every Linux Administrator needs Tools to monitor the system. Here we want to display some Tools for monitoring servers that can be accessed through the Web GUI. Some of them are available for free or have a trial version. First, let’s see what is system monitoring and get through the tools for it.

What is System Monitoring in Linux Server?

When the word System Monitoring comes up, means that you can track every piece of information on your server. You can use monitoring tools to track your CPU and memory usage, how much storage you have, check your hardware temperature, the activity of your network, etc.

Here you can see the following list of why system monitoring is so helpful.

Benefits of Linux System Monitoring
Detect all the server and network problems.
Find the root cause of the failure.
Help in reducing the maintenance cost.
Troubleshoot the performance issues.
Help to update system before it gets outdated.
Fix problems automatically when detected.
Make sure the servers, services, applications, and network is always up and running.
Help to update the system before it gets outdated.

Introduce the Best Linux System Monitoring GUI Tools

Here we provide a key feature list of Prometheus to see why it is a good choice for your system monitoring.

Prometheus Monitoring Tool Features Description
1Multidimensional data modelUsing time-series data, which is identified by metric name and key-value pairs.
2PromQLA flexible querying language that can leverage the multi-dimensional data model.
3No reliance on distributed storagesingle server nodes are autonomous.
4Pull modelPrometheus can collect time-series data by actively “pulling” data over HTTP.
5Pushing time-series dataAvailable through the use of an intermediary gateway.
6Monitoring target discoveryAvailable through static configuration or service discovery.
7VisualizationPrometheus offers multiple types of graphs and dashboards.

Also, you can use Grafana with Prometheus. Prometheus collects rich metrics and provides a powerful querying language; Grafana transforms metrics into meaningful visualizations.
