What happened?
Description
We are using Azure Container Apps and sending the data to an OpenTelemetry collector, which forwards the telemetry to Application Insights (we send it to more than one backend for high availability). What we observe in Application Insights is that cloud_RoleInstance shows the instance ID instead of the host_name.
Steps to Reproduce
Setup an Azure Container App and send the telemetry to the Opentelemetry collector.
Expected Result
See in the cloud_RoleInstance the value of the host name
Actual Result
In the cloud_RoleInstance, we see the value of the service instance id
Proposed solution
In the exporter/azuremonitorexporter/contracts_utils.go, change from:
func applyCloudTagsToEnvelope(envelope *contracts.Envelope, resourceAttributes pcommon.Map) {
// Extract key service.* labels from the Resource labels and construct CloudRole and CloudRoleInstance envelope tags
// https://github.com/open-telemetry/opentelemetry-specification/tree/main/specification/resource/semantic_conventions
if serviceName, serviceNameExists := resourceAttributes.Get(string(conventions.ServiceNameKey)); serviceNameExists {
cloudRole := serviceName.Str()
if serviceNamespace, serviceNamespaceExists := resourceAttributes.Get(string(conventions.ServiceNamespaceKey)); serviceNamespaceExists {
cloudRole = serviceNamespace.Str() + "." + cloudRole
}
envelope.Tags[contracts.CloudRole] = cloudRole
}
if serviceInstance, exists := resourceAttributes.Get(string(conventions.ServiceInstanceIDKey)); exists {
envelope.Tags[contracts.CloudRoleInstance] = serviceInstance.Str()
}
envelope.Tags[contracts.InternalSdkVersion] = getCollectorVersion()
}
for
func applyCloudTagsToEnvelope(envelope *contracts.Envelope, resourceAttributes pcommon.Map) {
// Extract key service.* labels from the Resource labels and construct CloudRole and CloudRoleInstance envelope tags
// https://github.com/open-telemetry/opentelemetry-specification/tree/main/specification/resource/semantic_conventions
if serviceName, serviceNameExists := resourceAttributes.Get(string(conventions.ServiceNameKey)); serviceNameExists {
cloudRole := serviceName.Str()
if serviceNamespace, serviceNamespaceExists := resourceAttributes.Get(string(conventions.ServiceNamespaceKey)); serviceNamespaceExists {
cloudRole = serviceNamespace.Str() + "." + cloudRole
}
envelope.Tags[contracts.CloudRole] = cloudRole
}
if serviceInstance, exists := resourceAttributes.Get(string(conventions.HostNameKey)); exists {
envelope.Tags[contracts.CloudRoleInstance] = serviceInstance.Str()
}
envelope.Tags[contracts.InternalSdkVersion] = getCollectorVersion()
}
