Zabbix Memory Monitoring Setup57

Memory monitoring is a critical aspect of ensuring the health and performance of your IT infrastructure. By monitoring memory usage, you can identify potential issues such as memory leaks or excessive consumption, and take proactive steps to address them before they impact your systems' performance.

Zabbix is a powerful open-source monitoring tool that provides comprehensive memory monitoring capabilities. In this article, we will guide you through the steps to set up memory monitoring in Zabbix, enabling you to effectively monitor your systems' memory usage and maintain optimal performance.

Prerequisites

Before setting up memory monitoring in Zabbix, you will need to ensure that the following prerequisites are met:* A Zabbix server is installed and configured
* A Zabbix agent is installed on each system you want to monitor
* The Zabbix agent is configured to connect to the Zabbix server

Configuring Zabbix Server

* Type: Zabbix agent
* Key: [used]
* Update interval: 60 seconds
9. Click on the Add button
10. Repeat steps 7-9 to create additional memory monitoring items, as desired (e.g., [total], [free])

Configuring Zabbix Agent

To configure memory monitoring on the Zabbix agent, follow these steps:1. Edit the Zabbix agent configuration file (usually located at /etc/zabbix/)
2. Add the following lines to the file:

2. Navigate to Monitoring > Graphs
3. Click on the Create graph button
4. Enter the following information:
* Name: Memory Usage
* Type: Line
* Item: Memory Used
5. Click on the Add button
6. Configure the graph settings as desired

To create a trigger, follow these steps:1. Log in to the Zabbix web interface
2. Navigate to Configuration > Triggers
3. Click on the Create trigger button
4. Enter the following information:
* Name: Memory Usage High
* Expression: {hostname:[used].last()}>90
* Severity: High
5. Click on the Add button
6. Configure the trigger settings as desired

Conclusion

By following the steps outlined in this article, you can effectively set up memory monitoring in Zabbix. This will provide you with valuable insights into your systems' memory usage, enabling you to proactively identify and address potential issues. Regular monitoring of memory usage is essential for maintaining the health and performance of your IT infrastructure
