Click Review + Create then Create

Option 2: Azure CLI

# Set variables
export RESOURCE_GROUP="myResourceGroup"
export WORKSPACE_ID="/subscriptions/xxx/resourcegroups/xxx/providers/microsoft.operationalinsights/workspaces/xxx"
export API_KEY="your-semperis-api-key"
export LOCATION="eastus"

# Deploy
az deployment group create \
  --name semperis-connector \
  --resource-group $RESOURCE_GROUP \
  --template-file azuredeploy_Connector_SemperisLightning_AzureFunction.json \
  --parameters \
    LogAnalyticsWorkspaceResourceID="$WORKSPACE_ID" \
    SemperisApiKey="$API_KEY" \
    SemperisZone="na" \
   ConnectorSchedule="0 * * * * *"

What Gets Created

The template creates:

7 Custom Log Analytics Tables (all with _CL suffix)
1 Data Collection Endpoint (DCE)
7 Data Collection Rules (DCRs)
Azure Function App (Python 3.11, Elastic Premium Plan)
Storage Accounts (for function runtime and state)
Key Vault (for secure API key storage)
Application Insights (for monitoring)
User-Assigned Managed Identity (for authentication)

Data Ingestion Schedule

By default, the connector ingests data every 1 hour. You can modify the schedule using CRON expressions:

Expression	Frequency
`0 * * * * *`	Every 1 hour (default)
`0 /4 * * *`	Every 4 hours
`0 * * * * *`	Every hour
`0 0 * * * *`	Daily at midnight UTC

Monitoring

Application Insights: Check function health in Azure Portal

Log Analytics: Query the custom tables for data
