Azure Virtual Network Gateway

Collect metrics data from Azure Virtual Network Gateway

Configuration¶

Install Func¶

We recommend enabling the Guance integration - extension - DataFlux Func (Automata): all prerequisites are automatically installed. Please proceed with the script installation.

If you deploy Func yourself, refer to Self-deployed Func

Install Script¶

Note: Please prepare the required Azure application registration information in advance and assign the Monitoring Reader role to the application registration.

To synchronize Azure Virtual Network Gateway monitoring data, we install the corresponding collection script: "Integration (Azure-Virtual Network Gateway Collection)" (ID: guance_azure_virtual_network_gateway)

After clicking 【Install】, enter the corresponding parameters:

Azure Tenant ID: Tenant ID
Azure Client ID: Application Registration Client ID
Azure Client Secret Value: Client secret value, note that it is not the ID
Subscriptions: Subscription ID, multiple subscriptions can be separated by ,

Click 【Deploy Start Script】, the system will automatically create a Startup script set and automatically configure the corresponding startup script.

After enabling, you can see the corresponding automatic trigger configuration in "Manage / Automatic Trigger Configuration". Click 【Execute】 to run it immediately without waiting for the scheduled time. After a short wait, you can view the execution task records and corresponding logs.

Verification¶

In "Manage / Automatic Trigger Configuration", confirm whether the corresponding tasks have the corresponding automatic trigger configurations. You can also check the corresponding task records and logs to see if there are any abnormalities.
On the Guance platform, in "Infrastructure - Resource Catalog", check if asset information exists.
On the Guance platform, in "Metrics", check if there are corresponding monitoring data.
