Name | Type | Description |
|---|---|---|
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 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 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 |
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 |
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. |
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 |
Server Compilation Settings

Name | Type | Description |
|---|---|---|
fips_mode | Gauge | Integer representing whether the envoy build is FIPS compliant or not |
