The trace metrics namespace is trace.<NAME>.<METRICS>{<TAGS>}.
Tracing application metrics are collected after enabling trace collection and instrumenting your application. These metrics are available for dashboards and monitors.
Trace metric names are formatted as trace.<NAME>.<METRIC> or trace.<NAME>.<METRIC_2ND_PRIM_TAG>.
| Parameter | Description |
|---|---|
<NAME> | The name of the operation or span.name (examples: redis.command, pylons.request, rails.request, mysql.query). |
<METRIC> | The name of the metric (examples: duration, hits, span_count). |
<METRIC_2ND_PRIM_TAG> | If the metric name accounts for the second primary tag, this tag is part of the metric name. |
Trace metrics come with a variety of tags. The possible tags are:
