Introduction and Usage of Fine-Grain Logger, Admin Console Primer, and Envoy’s Universal HTTP Validator
summary
Three short updates: a fine-grain logger adds file-path and glob ( and ?) runtime log level control via admin POSTs, supports multiple updates per request, shows CPU performance improvements versus component logging in stress tests and runs in Google’s global load balancer; the admin console surfaces detailed histograms, an active HTML view that sorts hottest-changing stats, config dumps and live logging control via curl or web UI; the Universal HTTP Validator* centralizes HTTP/1/2/3 validation to eliminate seven CVEs, uses a differential fuzzer to verify compatibility, ships with a compatibility mode and targets availability end of 2023.
