DevOps/Github service notifications using Azure Logic Apps

Github/DevOps service status

As described in one of my previous post, you can easily check the health status of services like Github and DevOps by going to each services status page. Below is a link to my previous post:

Additionally, both Github and DevOps status pages have RSS feeds we can subscribe to. The Azure platform itself also has its own health status page at the following URL: https://status.azure.com/en-us/status/.

In todays tutorial we will create and configure an Azure Logic App that will connect to each of these services RSS feeds and send us email notifications when services become degraded, health issues occur or get remediated.

What is an Azure Logic app?

Azure Logic Apps is a cloud-based platform for creating and running automated workflows that integrate your apps, data, services, and systems. With this platform, you can quickly develop highly scalable integration solutions for your enterprise and business-to-business (B2B) scenarios. As a member of Azure Integration Services, Logic Apps simplifies the way that you connect legacy, modern, and cutting-edge systems across cloud, on premises, and hybrid environments.

What do we need?

  1. Azure Logic App: We will create a multi-tenant logic app using the Consumption pricing plan.
  2. Email Account: We will also need an email account from a service that works with Azure Logic Apps, such as Outlook.com. For other supported email providers, review Connectors for Azure Logic Apps.

Creating the Logic App

In the Azure portal search for logic app and then add and create the logic app with the following configuration. Under the Basics blade, add the following Instance Details:

Name Value
Type Consumption
Logic App name {Name}
Region {Region}

create

Add any tags optionally and then select Review + Create, and create the Logic App.

Configuring the Logic App

After the Logic App has been created navigate to the resource, once you click on the resource, the Azure portal will navigate into the Logic Apps Designer, here we will select a new Blank Logic App:

blank01

First we will create a schedule trigger. On the connectors and triggers search bar type: schedule and select the trigger called recurrence:

schedule

We will set this trigger to run every 3 minutes:

time

Next we will add each of our RSS feeds as parallel branches after our schedule. Click on + New step underneath the recurrence schedule trigger and search for rss. We will add the action "List all RSS feed items" 3x times as we want to check three RSS feeds, one for each of the following service:

  1. https://www.githubstatus.com/history.rss - Github RSS status feed.
  2. https://status.dev.azure.com/_rss - Azure Devops RSS status feed.
  3. https://azurestatuscdn.azureedge.net/en-gb/status/feed/ - Azure platform RSS status feed.

rss_actions

We will configure each action under our recurring schedule with the following values:

Parameter Name Value
The RSS feed URL {RSS URL Feed}
since addminutes(utcnow(), -3)

NOTE: We are using the since parameter and an expression addminutes(utcnow(), -3) as the value, which will instruct our logic app to check the configured RSS feed URL for any new posts within the last 3 minutes. Since our logic app will run on a recurring schedule every 3 minutes, checking for new posts within the last 3 minutes, we should never miss any health status updates.

function

Also note that we can rename our RSS action so that it is easier to identify:

rename03

After configuring up our first RSS action, underneath our schedule trigger we will click on the + sign and select the option to add a parallel branch:

parallel01

Similarly to how we configured our first action, we will add an action for our devops status RSS feed and repeat the process a third time to add our azure status RSS feed. After adding all our feeds as parallel branch actions, our Logic App designer should look like this:

actions_final

Now that all 3x RSS actions have been set up, the last thing we need to do is configure our email actions. We will create 3x email actions, one for each RSS feed. After each action you will see a + sign. Click on the + and select Add an action:

action01

Search for control and then select the action for each:

fore_each

We can again rename our control action so that it is easier to identify. In my case I have named these control actions githubFeedItem, devopsFeedItem and azureFeedItem.

For each control action we will configure the RSS Body as the output from the previous step and then add an action. In the search box, enter send an email so that you can find connectors that offer this action. If you have a Microsoft work or school account and want to use Office 365 Outlook. Or, if you have a personal Microsoft account, select Outlook.com. This example continues with Outlook.com. Select Send and email (V2):

email02

Many connectors require that you first create a connection and authenticate your identity before you can continue. Our selected email service prompts us to sign in and authenticate our identity before we can continue:

auth

Once authenticated we can configure our e-mail template:

template01

Note that we can populate our email template with dynamic content to add details about the RSS feed we configured earlier taking the values dynamically from the Body of the RSS feed response:

dynamic

As you can see from the next screen, I have created 3x email actions, each with their own unique email template for each given RSS status feed:

final03

Remember to save the logic app when finished. That is it! Optionally we can select Run Trigger to manually trigger a test run of the Logic App we just created.

save

Now every time a new health status is posted to any of our configured RSS feeds, we will be notified via an email notification containing the details of the affected service.

mail01

mail02

I hope you have enjoyed this post and have learned something new. You can also find the JSON code sample and template of the Logic App we built in this tutorial on my Github page. ❤️
