====== Modifying Threshold Values in Zabbix ======

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

===== Steps: =====

1. **Access Zabbix Frontend:**
  * Log in to your Zabbix frontend using your credentials.

2. **Navigate to Templates:**
  * Go to the "Configuration" tab and select "Templates" from the dropdown menu.

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:
<code>
     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
</code>
  * Update the time condition from "5m" to "20m".

5. **Exclude Specific Service:**
  * Add the condition '<> "edgeupdate"' to exclude the 'edgeupdate' service:
<code>
     min(/Windows by Zabbix agent/service.info["{#SERVICE.NAME}",state],#3)<>0 and {#SERVICE.NAME}<>"edgeupdate"
</code>

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.


===== Note: =====
  *  Ensure accurate syntax while modifying trigger expressions.
  *  Test the changes to verify their effectiveness in monitoring and alerting.
