Statistics¶
Server¶
Server related statistics are rooted at server. with following statistics:
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 –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. |
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 |
