Learn how to effectively monitor your Linux servers using Checkmk software. This guide will walk you through the process of installing Checkmk and adding a monitoring agent, providing a well-designed web-based GUI dashboard for monitoring your servers, applications, networks, and cloud environments.
How to Start Monitoring with Checkmk
Access the Checkmk user interface through your web browser by entering the URL of your Checkmk site. Log in as the cmkadmin user and customize your profile. Explore the empty panel and familiarize yourself with the interface.
Monitoring Settings
Checkmk supports various monitoring methods, with the best one being through the use of Checkmk agents. Install the appropriate agent package for your Linux operating system. Test the agent to ensure it’s working properly by running the check_mk_agent command in your server terminal.
Adding a Host
After installing the agent, go back to the Configuration screen and select Hosts. Click “Add Host” and provide the hostname and IP address. Checkmk can automatically resolve the IP address to the hostname if you have DNS configured, or you can manually add the IP address. Save the settings and go to the service settings to monitor all discovered services.
Fixing Host Monitoring
Activate your changes by clicking the yellow exclamation point icon in the upper right corner. This ensures that your changes take effect. Checkmk differentiates between the configuration environment and the monitoring environment, and changes must be explicitly activated before they impact the monitoring process.
SNMP Monitoring
In addition to server monitoring, Checkmk also allows you to monitor network devices using SNMP. Enable the SNMP agent on the device you want to monitor and ensure that your Checkmk server can access it. Add the host in Checkmk, select SNMP, and configure the SNMP version and credentials if necessary. Checkmk will automatically detect monitoring services for SNMP-enabled devices.
