Azure Monitor Exporter

This exporter sends logs and trace data to Azure Monitor.

Configuration

The following settings are required:

• instrumentation_key (no default): Application Insights instrumentation key, which can be found in the Application Insights resource in the Azure Portal.

The following settings can be optionally configured:

• endpoint (default = https://dc.services.visualstudio.com/v2/track): The endpoint URL where data will be submitted.
• maxbatchsize (default = 1024): The maximum number of telemetry items that can be submitted in each request. If this many items are buffered, the buffer will be flushed before maxbatchinterval expires.
• maxbatchinterval (default = 10s): The maximum time to wait before sending a batch of telemetry.

Example:

exporters:
  azuremonitor:
    instrumentation_key: b1cd0778-85fc-4677-a3fa-79d3c23e0efd

Attribute mapping

Traces

This exporter maps OpenTelemetry trace data to Application Insights data model using the following schema.

The OpenTelemetry SpanKind determines the Application Insights telemetry type.

OpenTelemetry SpanKind	Application Insights telemetry type
CLIENT, PRODUCER, INTERNAL	Dependency
SERVER, CONSUMER	Request

The exporter follows the semantic conventions to fill the Application Insights specific telemetry properties. The following table shows a basic mapping.

Application Insights property	OpenTelemetry attribute	Default
Request.Name	http.method, http.route or rpc.system	span name
Request.Url	http.scheme, http.host, http.target
Request.Source	http.client_ip or net.peer.name
Request.ResponseCode	http.status_code or status_code	"0"
Request.Success	http.status_code or status_code	true
Dependency.Name	http.method, http.route	span name
Dependency.Data	http.url or span name or db.statement
Dependency.Type	"HTTP" or rpc.system or db.system or "InProc"
Dependency.Target	host of http.url or net.peer.name
Dependency.ResultCode	http.status_code or status_code	"0"
Dependency.Success	http.status_code or status_code	true

The exact mapping can be found here.

All attributes are also mapped to custom properties if they are booleans or strings and to custom measurements if they are ints or doubles.

Logs

This exporter saves log records to Application Insights traces table. TraceId is mapped to operation_id column and SpanId is mapped to operation_parentId column.
