Prometheus Labels

Prometheus metrics can contain labels which can be used with a metric to differentiate metrics returned by the metrics endpoint from each other. For example the label service="createCustomer" used with the metric sag_is_service_requests_total indicates that the metric describes the total number of requests made in the last polling interval for the service createCustomer. Whereas the label service="updateCustomer" used with the same metric indicates the total number of requests made in the last polling interval for the service updateCustomer.

Prometheus Label	Description
apiCat	API Category for a service invocation. API_GRAPHQL API_ODATA API_REST API_SOAP API_WEBSOCKET (Outbound service calls to a remote WebSocket listener only.)
code	An integer value associated with the metric. The code relates to the type of service that is executing. For example, a service that receives an HTTP response will have an HTTP status code.
execStat	The execution state of the service. The execStat can be one of the following values: Y for service success. N for service failure. U for unknown which indicates the service had not yet executed completion at the time the metrics were gathered.
host.	Host name of theMicroservices Runtime in the format: <hostname\|ipaddress> .
name	Name associate with the metric. The name value varies and depends on the data in the metric. For example, if the metric is for a service, the name might be the service name. If the metric is for a memory-related metric, the name might be the memory pool name.
origin	Origin for the service invocation. The type of origin information will vary per apiCat. For example for a service invocation for an API_REST call, the origin is the REST resource endpoint. For an API_SOAP call, the origin is a service endpoint.
poolType	Type of memory pool as returned by java.lang.management.MemoryPoolMXBean.getType. The type name varies depending on the JDK implementation.
service	Fully qualified name of a service.
