+# Tsung — нагрузка EventHub
+
+## Профили
+
+| Файл | Назначение |
+|------|------------|
+| `eventhub_ift_smoke.xml` | Короткий smoke на IFT после prepare |
+| `eventhub_ift.xml` | Mix: `auth_browse` 60% + `create_flow` 40%, фазы warmup/ramp/peak |
+| `eventhub_tsung.xml` | Legacy localhost (thinktime там в секундах — не использовать для IFT) |
+| `eventhub_http.xml` | Legacy короткий localhost |
+
+Цель IFT: **HTTPS** `api.ift.eventhub.local:443` (Traefik).
+
+Auth path: `POST /v1/register` → `POST /v1/verify` → `POST /v1/login`.  
+На стендах (`EVENTHUB_ENV` ≠ `prod`) register отдаёт `verification_token` (без почты).
+
+## Перед прогоном (хост IFT)
+
+```bash
+# 1 нода (default)
+EVENTHUB_REPLICAS=1 bash /opt/eventhub-ift/devops/scripts/ift-loadtest-prepare.sh
+
+# или N нод
+EVENTHUB_REPLICAS=2 bash /opt/eventhub-ift/devops/scripts/ift-loadtest-prepare.sh
+```
+
+Оставляет `traefik` + `eventhub×N`, гасит admin-ui / bot / observability / fallback.
+
+## Дех-машина (WSL)
+
+1. DNS: `api.ift.eventhub.local` → IP IFT (тот же, что в OpenWRT).
+2. Установка: `sudo apt install tsung` (или [документация Tsung](http://tsung.erlang-projects.org/)).
+3. TLS: самоподписанный сертификат стенда — импортировать CA из `EventHubDevOps/ift/traefik/certs` в trust store WSL, либо временно положить CA в `/usr/local/share/ca-certificates/` и `update-ca-certificates`. Проверка: `curl -sf https://api.ift.eventhub.local/health`.
+4. Запуск из корня `EventHubBack`:
+
+```bash
+# smoke (~1 мин)
+tsung -f test/tsung/eventhub_ift_smoke.xml start
+
+# полный прогон (~6 мин фаз)
+tsung -f test/tsung/eventhub_ift.xml start
+```
+
+Отчёт: `~/.tsung/log/<timestamp>/` → `tsung_stats.pl` / HTML.
+
+## После прогона
+
+```bash
+bash /opt/eventhub-ift/devops/scripts/ift-loadtest-restore.sh
+```
+
+## Настройка интенсивности
+
+В `eventhub_ift.xml` блок `<load>`: `interarrival` (сек между стартами пользователей) и `duration` фаз.  
+`thinktime` — **секунды** (не мс).
+
+## Что сознательно убрано из hot path
+
+- dummy `/v1/refresh`
+- reports / tickets (шум модерации)
+- завышенные thinktime (старый `eventhub_tsung.xml`)
