AzureTracing metrics

Azuretracing metrics collects latency and latency from azure-sdk-for-go and creates metrics and is controllable using environment variables (eg. setting buckets, disabling metrics or disable autoreset).

Metric	Description
azurerm_api_ratelimit	Azure ratelimit metrics (only on /metrics, resets after query due to limited validity)
azurerm_api_request_*	Azure request count and latency as histogram

Settings

Environment variable	Example	Description
METRIC_AZURERM_API_REQUEST_BUCKETS	1, 2.5, 5, 10, 30, 60, 90, 120	Sets buckets for azurerm_api_request histogram metric
METRIC_AZURERM_API_REQUEST_ENABLE	false	Enables/disables azurerm_api_request_* metric
METRIC_AZURERM_API_REQUEST_LABELS	apiEndpoint, method, statusCode	Controls labels of azurerm_api_request_* metric
METRIC_AZURERM_API_RATELIMIT_ENABLE	false	Enables/disables azurerm_api_ratelimit metric
METRIC_AZURERM_API_RATELIMIT_AUTORESET	false	Enables/disables azurerm_api_ratelimit autoreset after fetch

azurerm_api_request label	Status	Description
apiEndpoint	enabled by default	hostname of endpoint (max 3 parts)
routingRegion	enabled by default	detected region for API call, either routing region from Azure Management API or Azure resource location
subscriptionID	enabled by default	detected subscriptionID
tenantID	enabled by default	detected tenantID (extracted from jwt auth token)
resourceProvider	enabled by default	detected Azure Management API provider
method	enabled by default	HTTP method
statusCode	enabled by default	HTTP status code

Azure module

Tag handling

Tag can be dynamically added to metrics and processed though filters

format is: tagname?filter1 or tagname?filter1&filter2

Tag filter	Description
toLower	Lowercasing Azure tag value
toUpper	Uppercasing Azure tag value
