.. _statistics:
.. _server_statistics:
Server related statistics are rooted at server. with following statistics:
.. csv-table:: :header: Name, Type, Description :widths: 1, 1, 2
uptime, Gauge, Current server uptime in seconds
concurrency, Gauge, Number of worker threads
memory_allocated, Gauge, Current amount of allocated memory in bytes. Total of both new and old Envoy processes on hot restart.
memory_heap_size, Gauge, Current reserved heap size in bytes. New Envoy process heap size on hot restart.
memory_physical_size, Gauge, Current estimate of total bytes of the physical memory. New Envoy process physical memory size on hot restart.
live, Gauge, "1 if the server is not currently draining, 0 otherwise"
state, Gauge, Current :ref:State <envoy_v3_api_field_admin.v3.ServerInfo.state> of the Server.
parent_connections, Gauge, Total connections of the old Envoy process on hot restart
total_connections, Gauge, Total connections of both new and old Envoy processes
version, Gauge, Integer represented version number based on SCM revision or :ref:stats_server_version_override <envoy_v3_api_field_config.bootstrap.v3.Bootstrap.stats_server_version_override> if set.
days_until_first_cert_expiring, Gauge, Number of days until the next certificate being managed will expire
seconds_until_first_ocsp_response_expiring, Gauge, Number of seconds until the next OCSP response being managed will expire
hot_restart_epoch, Gauge, Current hot restart epoch -- an integer passed via command line flag --restart-epoch usually indicating generation.
hot_restart_generation, Gauge, Current hot restart generation -- like hot_restart_epoch but computed automatically by incrementing from parent.
initialization_time_ms, Histogram, Total time taken for Envoy initialization in milliseconds. This is the time from server start-up until the worker threads are ready to accept new connections
debug_assertion_failures, Counter, Number of debug assertion failures detected in a release build if compiled with --define log_debug_assert_in_release=enabled or zero otherwise
envoy_bug_failures, Counter, Number of envoy bug failures detected in a release build. File or report the issue if this increments as this may be serious.
envoy_notifications, Counter, Number of envoy notifications detected. File or report the issue if this increments as this may be serious. Please include logs from the notification component at the debug level. See :ref:command line option --component-log-level <operations_cli> for details.
static_unknown_fields, Counter, Number of messages in static configuration with unknown fields
dynamic_unknown_fields, Counter, Number of messages in dynamic configuration with unknown fields
wip_protos, Counter, Number of messages and fields marked as work-in-progress being used
stats_overflow.counter, Counter, Total number of counter lookup or creation attempts dropped due to reaching the configured limit on label cardinality.
stats_overflow.gauge, Counter, Total number of gauge lookup or creation attempts dropped due to reaching the configured limit on label cardinality.
stats_overflow.histogram, Counter, Total number of histogram lookup or creation attempts dropped due to reaching the configured limit on label cardinality.
.. _server_compilation_settings_statistics:
Server Compilation Settings related statistics are rooted at server.compilation_settings. with following statistics:
.. csv-table:: :header: Name, Type, Description :widths: 1, 1, 2
fips_mode, Gauge, Integer representing whether the envoy build is FIPS compliant or not
