Linux Monitor
Introduction
Linux monitor involves the process of tracking and managing the performance, resource utilization, and health of a Linux-based operating system environment. Linux is a popular open-source operating system kernel used in various distributions, such as Ubuntu, CentOS, Debian, and Red Hat. Monitor Linux systems is essential to ensure optimal performance, identify bottlenecks, and address potential issues promptly.
Getting Started
Compatibility
vuSmartMaps supports the monitoring of your Linux operating system's various components including hardware, software, network, and applications.
Data Collection Method
vuSmartMaps collects health and performance data for Linux server using VuNet's Healthbeat agent. This agent collects data based on the source configuration.
Prerequisites
Inputs for Configuring Data Source
- Host: The IP Address/FQDN of the linux server. This field is the key to identify each server you add here.
- Period [in seconds]: How frequently data is gathered. Period should be between 60 seconds - 3000 seconds.
Firewall Requirement
To collect data from this O11ySource, ensure the following ports are opened:
| Source IP | Destination IP | Destination Port | Protocol | Direction |
|---|---|---|---|---|
| IP address of the Linux server | vuSmartMaps Data Collector End Point | 9092* | TCP | Inbound |
*Before providing the firewall requirements, please update the port based on the customer environment.
Configuring the Target
Healthbeat should be installed and running in the Linux server.
Configuration Steps
Enablethe O11ySource.- Select the Sources tab and press the
+button to add a new Linux host to be monitored. - Add the required details and then click on
Next. - The following packages will be available for download based on the OS:Healthbeat full installer package - Downloads the full Healthbeat package with required configurations for a fresh installationHealthbeat config update package - Downloads the agent configuration package to update an existing Healthbeat installation
- Download the agent installation or update package, then click Finish to close the data source window.
