3 Receiving notification on unsupported items

Overview

It is possible to receive notifications on unsupported items in Zabbix.

It is part of the concept of internal events in Zabbix, allowing users to be notified on these occasions. Internal events reflect a change of state:

• when items go from 'normal' to 'unsupported' (and back);
• when triggers go from 'normal' to 'unknown' (and back);
• when low-level discovery rules go from 'normal' to 'unsupported' (and back).

This section presents a how-to for receiving notification when an item turns unsupported.

Configuration

Overall, the process of setting up the notification should feel familiar to those who have set up alerts in Zabbix before.

Step 1

Configure some media, such as email, SMS, or script to use for the notifications. Refer to the corresponding sections of the manual to perform this task.

Step 2

Go to Alerts → Actions → Internal actions.

Click on Create action at the top right corner of the page to open an action configuration form.

Step 3

In the Action tab enter a name for the action. Then click on Add in the Conditions block to add a new condition.

In the New condition pop-up window select "Event type" as the condition type and then select "Item in 'not supported' state" as the event type.

Don't forget to click on Add to actually list the condition in the Conditions block.

Step 4

In the Operations tab, click on Add in the Operations block to add a new operation.

Select some recipients of the message (user groups/users) and the media type (or "All") to use for delivery. Check the Custom message checkbox if you wish to enter the custom subject/content of the problem message.

Click on Add to actually list the operation in the Operations block.

If you wish to receive more than one notification, set the operation step duration (interval between messages sent) and add another step.

Step 5

The Recovery operations block allows to configure a recovery notification when an item goes back to the normal state. Click on Add in the Recovery operations block to add a new recovery operation.

Select the operation type "Notify all involved". Select Custom message checkbox if you wish to enter the custom subject/content of the problem message.

Click on Add in the Operation details pop-up window to actually list the operation in the Recovery operations block.

Step 6

When finished, click on the Add button at the bottom of the form.

And that's it, you're done! Now you can look forward to receiving your first notification from Zabbix if some item turns unsupported.
