Teams is Microsoft’s chat and video conferencing solution. In the business variant, you can create channels for your teams and receive notifications from Checkmk in these. The connection to Teams is made via a webhook.
1. Configuring Microsoft Teams
In Teams you only need to create a webhook:
Enter the desired channel.
Open the three-dot menu in the upper right corner and select Connectors.
Add an Incoming Webhook.
Open the menu again and click Configure for Incoming Webhook.
Copy the generated URL.
2. Configuring Checkmk
You have already learned how to set up Checkmk notifications in general in the article on notifications.
In Checkmk it is now sufficient to specify the URL copied above:
Create a new notification rule with Setup > Events > Notifications > Add rule.
For the Notification Method choose Microsoft Teams.
-
Enter the copied URL under Webhook URL:
Instead of entering the URL directly here, you can also read it from the password store - provided it was previously stored there.
When using the following Contact selection box, note the following two points:
When selecting contacts, make sure that the notifications are only sent to one contact, e.g. by selecting a single user. With the notification methods for ticket systems etc., the contact selection only serves to specify that notifications are sent. However, the notifications are not sent to the selected user, but to the ticket system. Note that a contact selection via contact groups, all contacts of an object or similar usually generates several identical notifications for an event, which then end up in the ticket system twice, three times or even more often.
If the first point is fulfilled, but the user is used in several notification rules for the same method, then only the last rule applies in each case. It is therefore advisable to create a separate functional user for each of these notification rules.
You can find out how to test the new notification method in the article on notifications.
