Objective: To adjust threshold values for monitoring conditions in Zabbix templates.

1. Access Zabbix Frontend:

• Log in to your Zabbix frontend using your credentials.

2. Navigate to Templates:

3. Select Template:

• Locate the relevant template (e.g., Linux template for system monitoring) and click on it to open.

4. Modify Load Average Trigger:

• Within the template, find the Load Average Trigger.
• The trigger expression might resemble:

     min(/Linux by Zabbix agent/system.cpu.load[all,avg1],5m)/last(/Linux by Zabbix agent/system.cpu.num)>{$LOAD_AVG_PER_CPU.MAX.WARN} and last(/Linux by Zabbix agent/system.cpu.load[all,avg5])>0 and last(/Linux by Zabbix agent/system.cpu.load[all,avg15])>0

• Unordered List ItemUpdate the time condition from “5m” to “20m”.

5. Exclude Specific Service:

• Unordered List ItemAdd the condition '<> “edgeupdate”' to exclude the 'edgeupdate' service:

     min(/Windows by Zabbix agent/service.info["{#SERVICE.NAME}",state],#3)<>0 and {#SERVICE.NAME}<>"edgeupdate"

6. Apply Changes:

• Click on the item containing the modified threshold values.
• Hit the “Update” button to save the changes.
• Confirm the modifications by clicking “Update” again.

• Ensure accurate syntax while modifying trigger expressions.
• Test the changes to verify their effectiveness in monitoring and alerting.
