# Azure Express Route Circuit pattern-based discovery

Discovery and Service Mapping Patterns finds Azure Express Route Circuit resources on your cloud environment. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Pattern-based discovery and mapping requirements

Verify the Azure discovery prerequisites section in [Microsoft Azure Cloud discovery using patterns](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery-and-service-mapping-patterns/azure-cloud-discovery-patterns.md).

## Data collected by Discovery during horizontal discovery

Discovery populates the data in the CMDB when running the Azure - Express Route Circuit \(LP\) pattern.

|Field|Description|
|-----|-----------|
|Object ID \[object\_id\]|The unique Azure resource identifier for the Express Route Circuit.|
|Name \[name\]|The name of the Express Route Circuit.|
|State \[state\]|The current state of the Express Route Circuit.|
|VLAN ID \[vlanid\]|The Virtual LAN \(VLAN\) identifier assigned to the Express Route Circuit.|
|Install Status \[install\_status\]|Install status of the resource. Default value is Installed.|

## CI relationships

The Azure - Express Route Circuit \(LP\) pattern creates these relationships to support Azure Express Route Circuit discovery.

|CI|Relationship|CI|
|---|------------|---|
|Resource Group \[cmdb\_ci\_resource\_group\]|Contains::Contained by|Cloud Direct Connect \[cmdb\_ci\_cloud\_direct\_connect\]|
|Cloud Direct Connect \[cmdb\_ci\_cloud\_direct\_connect\]|Hosted on::Hosts|Azure Datacenter \[cmdb\_ci\_azure\_datacenter\]|
|Key Value \[cmdb\_key\_value\]|References|Cloud Direct Connect \[cmdb\_ci\_cloud\_direct\_connect\]|

## Azure Tag discovery

The Azure - Express Route Circuit \(LP\) pattern collects tags and populates them in the Key Value \[cmdb\_key\_value\] table.

|Field|Description|
|-----|-----------|
|Key \[key\]|Tag name.|
|Value \[value\]|Tag value.|
|Configuration item \[configuration\_item\]|References the Cloud Direct Connect \[cmdb\_ci\_cloud\_direct\_connect\] table.|
