In this article, we will look at configuring Harmony Controller to send alerts to a Microsoft Teams channel (webhook URL).

## Objective

Here we have a Thunder device with the following virtual service:

```yaml
slb virtual-server DOH-VIP 100.64.1.250 
 port 53 dns-udp 
  service-group SG-DNS 
  template dns dns1 

```

We want to monitor the status of this service and send an alert from Harmony Controller to a Microsoft Teams channel when the service goes up or down.

## Pre-requisite

- The Thunder device should be registered with the Harmony Controller and mapped to a tenant on Harmony Controller. Here the Thunder device is mapped to the tenant Demo-DOH on Harmony Controller.
- A webhook URL for the Microsoft Teams channel to which we want to send the alert.

## Create a custom trigger

Under Monitor \> Alert:  
Choose the tab Triggers:

Choose a tenant (e.g. Demo-DOH):

Click on Add a Trigger:

Specify the matching conditions for the trigger.  
Here we match on the string “Service dns-udp on virtual server DOH-VIP port 53 is down”:

Click on Save.

Repeat the above steps for creating a trigger for the service being up.

## Add an action

Under Monitor \> Alert:  
Choose the tab Actions and click on Add an Action:

Here we want to send the alert to a Microsoft Teams channel and hence choose the option POST and specify the webhook URL for that channel:

Click on Save.  
The action will be created:

Choose the trigger and action we had created earlier:

Click on Save.

Repeat the above for creating an alert for the service being up.

Here is a summary of the two alerts:

## Verification

On the Thunder device:  
Manually disable the virtual service:

```yaml
vThunder(config)#slb virtual-server DOH-VIP 100.64.1.250
vThunder(config-slb vserver)# port 53 dns-udp
vThunder(config-slb vserver-vport)#disable

```

You will be able to see the alert for the service being down on Harmony Controller under Monitor \> Alert:  
Choose the tab Generated Alerts:

On the MS Teams channel, you should be able to see the alert. Here is a sample screenshot:
