Setup and Configuration
- Adding Azure Spring Apps while configuring a new Azure monitor
If you haven't configured an Azure monitor yet, add one by following the steps below:
- Log in to your Site24x7 account.
- Go to Cloud > Azure > Add Azure Monitor. You can also follow these steps to add an Azure monitor.
- During Azure monitor configuration, on the Edit Azure Monitor page, select Spring Apps from the Service/Resource Types drop-down.
- Adding Spring Apps to an existing Azure monitor
If you already have an Azure monitor configured for the tenant, you can add Azure Spring Apps by following the steps below:
- Log in to your Site24x7 account.
- Go to Cloud > Azure, select your Azure monitor, then go to any of the dashboards on the left pane of your Azure monitor.
- Click the hamburger
icon and select Edit, which brings you to the Edit Azure Monitor page. - On the Edit Azure Monitor page, select the corresponding Subscriptions and Resource Groups from the drop-down, select Azure Spring Apps from the Service/Resource Types drop-down, and click Save.
- After successful configuration, go to Cloud > Azure > Azure Monitor > Azure Spring Apps. Now you can view the discovered Azure Spring Apps.
It will take 15-30 minutes to discover new Azure resources. For immediate discovery of the selected configuration, go to the Infrastructure Dashboard of the Azure monitor, hover over the hamburger icon, and select Discover Now.
