Tracing application metrics are collected after enabling trace collection and instrumenting your application. These metrics are available for dashboards and monitors. The trace metrics namespace is formatted as:
trace.<SPAN_NAME>.<METRIC_SUFFIX>trace.<SPAN_NAME>.<METRIC_SUFFIX>.<2ND_PRIM_TAG>_serviceWith the following definitions:
<SPAN_NAME>span.name (examples: redis.command, pylons.request, rails.request, mysql.query).<METRIC_SUFFIX>duration, hits, span_count). See the section below.<2ND_PRIM_TAG><TAGS>env, service, version, resource, sublayer_type, sublayer_service, http.status_code, http.status_class, Datadog Agent tags (including the host and second primary tag). Note: Tags set on spans do not count and will not be available as tags for your traces metrics.trace.<SPAN_NAME>.hitsenv, service, version, resource, http.status_code, all host tags from the Datadog Host Agent, and the second primary tag.trace.<SPAN_NAME>.hits.by_http_statusenv, service, version, resource, http.status_class, http.status_code, all host tags from the Datadog Host Agent, and the second primary tag.trace.<SPAN_NAME>env, service, resource, resource_name, version, synthetics, and the second primary tag.trace.<SPAN_NAME>.errorsenv, service, version, resource, http.status_code, all host tags from the Datadog Host Agent, and the second primary tag.trace.<SPAN_NAME>.errors.by_http_statusenv, service, version, resource, http.status_class, http.status_code, all host tags from the Datadog Host Agent, and the second primary tag.Note: This is a deprecated namespace.
