Manual Close

Some templates doesn't allow to manual close of problems. Example: Mikrotik SNMP template which uses Template Module INterfaces SNMPv2.

From Gemini:

Method 2: Enable Manual Closing for Interface Triggers. If you want the ability to manually click “Close problem” in the Zabbix dashboard for these interface alerts, you must enable it in the parent template.

• Go to Configuration > Templates (or Data collection > Templates in Zabbix 6.0+).
• Find and click on Template Module Interfaces SNMPv2.
• Click on Discovery rules next to it, then click on Network interfaces discovery.
• At the top of the page, click on Trigger prototypes.
• Click on the trigger named: Interface {#IFNAME}({#IFALIAS}): Link down.
• Check the box for Allow manual close.
• Click Update.
• Note: You can now go to Monitoring > Problems, click the problem's acknowledgment status, check “Close problem”, and click update.

Changing the settings on a template or a trigger prototype does not retroactively apply to problems that are already open. Zabbix evaluates the Allow manual close permission at the exact moment the problem event is created. Because these specific alerts were generated before you changed the setting, the Close problem checkbox will remain greyed out for them. To clear those existing, stuck problems, choose one of the three options below:

Option 2: Force a New Discovery Cycle You can force Zabbix to drop the old trigger references and regenerate them with your new “Allow manual close” configuration:

• Go to Data collection > Hosts (or Configuration > Hosts) and click on your MikroTik device.
• Click on Discovery rules at the top.
• Find Network interfaces discovery and check the box next to it.
• Click the Execute now button at the bottom of the page to force an immediate interface scan.
• Note: If the problems don't update immediately, you can temporarily change the “Keep lost resources period” inside that discovery rule to 0 to force a complete wipe of dead alerts, then change it back.
