Statistics overview

Envoy outputs numerous statistics which depend on how the server is configured. They can be seen locally via the :http:get:/stats command and are typically sent to a :ref:statsd cluster <arch_overview_statistics>. The statistics that are output are documented in the relevant sections of the :ref:configuration guide <config>. Some of the more important statistics that will almost always be used can be found in the following sections:

• :ref:HTTP connection manager <config_http_conn_man_stats>
• :ref:Upstream cluster <config_cluster_manager_cluster_stats>
