Monitoring Integration and Runtime Deployment Engineering Journal

🔍 Overview

Fase ini menerjemahkan architecture contract yang telah diterima menjadi configuration contract, validation interface, dan runtime component yang dikonsumsi repository tomcat-monitoring. Baseline integration, runtime generik Telegraf dan Prometheus, scrape configuration, serta persistent lab Prometheus dengan named volumes telah tersedia. Isolated JMX TLS scrape, strict untrusted-CA failure, dan recovery telah diverifikasi tanpa mengubah persistent Prometheus. Runtime metric-name contract telah direkonsiliasi. Persistent lab JMX TLS scrape kemudian diterapkan dan diverifikasi dengan data volume yang sama. Lab-only Tomcat health application dan persistent Telegraf scrape juga telah diterapkan. Application-health alert dan missing-metric rules telah diimplementasikan, dimuat pada persistent Prometheus, dan lulus semantic serta isolated firing/resolved verification. Runtime ownership, internal lab interface, routing baseline, receiver boundary, dan secret reference contract Alertmanager telah ditetapkan. Source repository runtime generik Alertmanager kemudian dibentuk, lulus static validation, dan menghasilkan local image yang lulus Alertmanager, amtool, serta non-root smoke tests. Non-secret routing configuration, static validator, dan Prometheus API v2 delivery reference telah diimplementasikan dan lulus disposable semantic validation. Receiver lokal disposable kemudian membuktikan payload firing/resolved dan stable grouping labels tanpa persistent runtime atau external delivery. Direct Gmail email sempat dipilih sebagai lab notification channel, kemudian digantikan oleh Mailpit lokal agar SMTP capture tidak memerlukan Google credential atau external delivery. Direct-upstream exception, immutable v1.31.0 image, disposable topology, dan cleanup contract telah diterima. Source email receiver, semantic configuration, immutable image identity, isolated firing/resolved SMTP capture, serta exact cleanup kemudian diverifikasi pada TN-033. Persistent topology dan rollback boundary diterima pada TN-034. TN-035 kemudian menerapkan persistent Prometheus–Alertmanager–Mailpit flow dan membuktikan real application-health firing/resolved delivery beserta recovery baseline. TN-036 kemudian menetapkan persistent lab sebagai operator-managed environment dan menutup phase tanpa mengklaim automatic host-boot recovery. Full external integration tetap belum diterapkan dan dipisahkan sebagai future work.

🎯 Objective

Menyiapkan integrasi komponen monitoring dan deployment runtime tanpa melampaui keputusan, secret boundary, atau authorization yang tersedia.
