# Гайд по метрикам и мониторингу
|
||||||
|
|
||||||
|
## Быстрый старт
|
||||||
|
|
||||||
|
1. **Доступ к сервисам:**
|
||||||
|
- Приложение: http://localhost:8080
|
||||||
|
- Prometheus: http://localhost:9090
|
||||||
|
- Grafana: http://localhost:3000 (admin/admin)
|
||||||
|
|
||||||
|
2. **Дашборды автоматически загружены:**
|
||||||
|
- Spring Boot Application Metrics
|
||||||
|
- PostgreSQL & HikariCP Monitoring
|
||||||
|
|
||||||
|
## Основные метрики
|
||||||
|
|
||||||
|
### HTTP метрики
|
||||||
|
|
||||||
|
**Что смотреть:**
|
||||||
|
- `http_server_requests_seconds_count` — количество запросов
|
||||||
|
- `http_server_requests_seconds_sum` — суммарное время выполнения
|
||||||
|
- `http_server_requests_seconds_bucket` — распределение времени ответа
|
||||||
|
|
||||||
|
**Зачем:**
|
||||||
|
- Отслеживать нагрузку на эндпоинты
|
||||||
|
- Находить медленные запросы (p95, p99)
|
||||||
|
- Видеть ошибки по статус-кодам
|
||||||
|
|
||||||
|
**Пример запроса в Prometheus:**
|
||||||
|
```promql
|
||||||
|
# Request rate по эндпоинтам
|
||||||
|
rate(http_server_requests_seconds_count{application="todo"}[1m])
|
||||||
|
|
||||||
|
# 95-й перцентиль времени ответа
|
||||||
|
histogram_quantile(0.95, sum(rate(http_server_requests_seconds_bucket[5m])) by (le, uri))
|
||||||
|
|
||||||
|
# Количество ошибок 5xx
|
||||||
|
sum(rate(http_server_requests_seconds_count{status=~"5.."}[1m]))
|
||||||
|
```
|
||||||
|
|
||||||
|
### JVM метрики
|
||||||
|
|
||||||
|
**Что смотреть:**
|
||||||
|
- `jvm_memory_used_bytes` — используемая память (heap/non-heap)
|
||||||
|
- `jvm_memory_max_bytes` — максимальная доступная память
|
||||||
|
- `jvm_gc_pause_seconds` — время на GC паузах
|
||||||
|
- `jvm_threads_live_threads` — количество потоков
|
||||||
|
|
||||||
|
**Зачем:**
|
||||||
|
- Проверить утечки памяти (постоянный рост heap)
|
||||||
|
- Оптимизировать GC (частые паузы = проблема)
|
||||||
|
- Контролировать создание потоков
|
||||||
|
|
||||||
|
**Алерты:**
|
||||||
|
```promql
|
||||||
|
# Память heap больше 80%
|
||||||
|
(jvm_memory_used_bytes{area="heap"} / jvm_memory_max_bytes{area="heap"}) > 0.8
|
||||||
|
|
||||||
|
# GC паузы больше 100ms
|
||||||
|
rate(jvm_gc_pause_seconds_sum[1m]) > 0.1
|
||||||
|
```
|
||||||
|
|
||||||
|
### Database Connection Pool (HikariCP)
|
||||||
|
|
||||||
|
**Что смотреть:**
|
||||||
|
- `hikaricp_connections_active` — активные соединения
|
||||||
|
- `hikaricp_connections_idle` — простаивающие соединения
|
||||||
|
- `hikaricp_connections_pending` — ожидающие потоки
|
||||||
|
- `hikaricp_connections_timeout_total` — таймауты соединений
|
||||||
|
- `hikaricp_connections_acquire_seconds` — время получения соединения
|
||||||
|
|
||||||
|
**Зачем:**
|
||||||
|
- Настроить размер пула (если active = max постоянно, увеличить)
|
||||||
|
- Найти медленные запросы (высокое usage time)
|
||||||
|
- Обнаружить connection leaks (timeouts растут)
|
||||||
|
|
||||||
|
**Оптимальные значения:**
|
||||||
|
- Active connections < 70% от max
|
||||||
|
- Acquire time < 10ms (p95)
|
||||||
|
- Pending threads = 0
|
||||||
|
- Timeouts = 0
|
||||||
|
|
||||||
|
**Алерты:**
|
||||||
|
```promql
|
||||||
|
# Пул заполнен больше 80%
|
||||||
|
(hikaricp_connections_active / hikaricp_connections_max) > 0.8
|
||||||
|
|
||||||
|
# Таймауты соединений
|
||||||
|
rate(hikaricp_connections_timeout_total[1m]) > 0
|
||||||
|
|
||||||
|
# Медленное получение соединений (p95 > 50ms)
|
||||||
|
histogram_quantile(0.95, rate(hikaricp_connections_acquire_seconds_bucket[1m])) > 0.05
|
||||||
|
```
|
||||||
|
|
||||||
|
### System метрики
|
||||||
|
|
||||||
|
**Что смотреть:**
|
||||||
|
- `system_cpu_usage` — CPU системы
|
||||||
|
- `process_cpu_usage` — CPU процесса
|
||||||
|
- `disk_free_bytes` — свободное место на диске
|
||||||
|
|
||||||
|
**Зачем:**
|
||||||
|
- Контролировать нагрузку на CPU
|
||||||
|
- Предотвратить переполнение диска
|
||||||
|
|
||||||
|
## Использование Grafana
|
||||||
|
|
||||||
|
### Навигация по дашбордам
|
||||||
|
|
||||||
|
1. **Spring Boot Application Metrics:**
|
||||||
|
- HTTP Request Rate — количество запросов в секунду по эндпоинтам
|
||||||
|
- HTTP Request Duration — время ответа (p95, p99)
|
||||||
|
- HTTP Status Codes — распределение статус-кодов
|
||||||
|
- JVM Memory — использование heap/non-heap памяти
|
||||||
|
- Database Connection Pool — состояние пула соединений
|
||||||
|
- JVM Threads — количество потоков
|
||||||
|
- GC Pause Time — время на сборку мусора
|
||||||
|
- System CPU Usage — нагрузка на CPU
|
||||||
|
|
||||||
|
2. **PostgreSQL & HikariCP Monitoring:**
|
||||||
|
- Connection Pool Status — статистика пула (active, idle, total, pending)
|
||||||
|
- Connection Pool Utilization — процент использования пула
|
||||||
|
- Connection Acquire Time — время получения соединения (перцентили)
|
||||||
|
- Connection Timeout Count — количество таймаутов
|
||||||
|
- Connection Creation Time — время создания нового соединения
|
||||||
|
- Connection Usage Time — среднее время использования соединения
|
||||||
|
|
||||||
|
### Полезные функции Grafana
|
||||||
|
|
||||||
|
**Time Range:**
|
||||||
|
- Последние 5 минут — реал-тайм мониторинг
|
||||||
|
- Последний час — анализ недавних инцидентов
|
||||||
|
- Последние 24 часа — дневные паттерны
|
||||||
|
|
||||||
|
**Refresh:**
|
||||||
|
- 5s — активный мониторинг
|
||||||
|
- 30s — обычный режим
|
||||||
|
- Off — анализ истории
|
||||||
|
|
||||||
|
**Zoom:**
|
||||||
|
- Выдели область на графике для zoom-in
|
||||||
|
- Двойной клик — zoom-out
|
||||||
|
|
||||||
|
**Legend:**
|
||||||
|
- Клик на метрику — скрыть/показать
|
||||||
|
- Shift+клик — изолировать метрику
|
||||||
|
|
||||||
|
## Практические сценарии
|
||||||
|
|
||||||
|
### 1. Медленный эндпоинт
|
||||||
|
|
||||||
|
**Признаки:**
|
||||||
|
- Request Duration (p95) > 1s для конкретного URI
|
||||||
|
- Connection Acquire Time растет
|
||||||
|
|
||||||
|
**Диагностика:**
|
||||||
|
```promql
|
||||||
|
# Найти медленный эндпоинт
|
||||||
|
topk(5, histogram_quantile(0.95, sum(rate(http_server_requests_seconds_bucket[5m])) by (le, uri)))
|
||||||
|
|
||||||
|
# Проверить время получения соединения
|
||||||
|
histogram_quantile(0.95, rate(hikaricp_connections_acquire_seconds_bucket[1m]))
|
||||||
|
```
|
||||||
|
|
||||||
|
**Решение:**
|
||||||
|
- Оптимизировать SQL запрос
|
||||||
|
- Добавить индексы
|
||||||
|
- Включить кеширование
|
||||||
|
|
||||||
|
### 2. Memory Leak
|
||||||
|
|
||||||
|
**Признаки:**
|
||||||
|
- Heap memory постоянно растет
|
||||||
|
- Частые Full GC паузы
|
||||||
|
- OutOfMemoryError в логах
|
||||||
|
|
||||||
|
**Диагностика:**
|
||||||
|
```promql
|
||||||
|
# Рост памяти
|
||||||
|
jvm_memory_used_bytes{area="heap"}
|
||||||
|
|
||||||
|
# Частота GC
|
||||||
|
rate(jvm_gc_pause_seconds_count[1m])
|
||||||
|
```
|
||||||
|
|
||||||
|
**Решение:**
|
||||||
|
- Heap dump анализ (jmap)
|
||||||
|
- Проверить кеши и коллекции
|
||||||
|
- Закрывать ресурсы (connections, streams)
|
||||||
|
|
||||||
|
### 3. Connection Pool Exhausted
|
||||||
|
|
||||||
|
**Признаки:**
|
||||||
|
- Active connections = Max connections
|
||||||
|
- Pending threads > 0
|
||||||
|
- Timeouts растут
|
||||||
|
- Медленные запросы
|
||||||
|
|
||||||
|
**Диагностика:**
|
||||||
|
```promql
|
||||||
|
# Утилизация пула
|
||||||
|
(hikaricp_connections_active / hikaricp_connections_max) * 100
|
||||||
|
|
||||||
|
# Ожидающие потоки
|
||||||
|
hikaricp_connections_pending
|
||||||
|
|
||||||
|
# Таймауты
|
||||||
|
rate(hikaricp_connections_timeout_total[1m])
|
||||||
|
```
|
||||||
|
|
||||||
|
**Решение:**
|
||||||
|
- Увеличить `spring.datasource.hikari.maximum-pool-size`
|
||||||
|
- Найти медленные запросы
|
||||||
|
- Проверить connection leaks (незакрытые соединения)
|
||||||
|
|
||||||
|
### 4. Высокая нагрузка
|
||||||
|
|
||||||
|
**Признаки:**
|
||||||
|
- Request rate резко вырос
|
||||||
|
- CPU usage > 80%
|
||||||
|
- Response time увеличилось
|
||||||
|
|
||||||
|
**Диагностика:**
|
||||||
|
```promql
|
||||||
|
# Request rate
|
||||||
|
sum(rate(http_server_requests_seconds_count[1m]))
|
||||||
|
|
||||||
|
# CPU
|
||||||
|
system_cpu_usage
|
||||||
|
|
||||||
|
# Response time
|
||||||
|
histogram_quantile(0.95, sum(rate(http_server_requests_seconds_bucket[5m])) by (le))
|
||||||
|
```
|
||||||
|
|
||||||
|
**Решение:**
|
||||||
|
- Горизонтальное масштабирование (больше инстансов)
|
||||||
|
- Rate limiting
|
||||||
|
- Кеширование частых запросов
|
||||||
|
|
||||||
|
## Настройка алертов (опционально)
|
||||||
|
|
||||||
|
Создай файл `prometheus-alerts.yml`:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
groups:
|
||||||
|
- name: app_alerts
|
||||||
|
interval: 30s
|
||||||
|
rules:
|
||||||
|
- alert: HighErrorRate
|
||||||
|
expr: rate(http_server_requests_seconds_count{status=~"5.."}[1m]) > 0.1
|
||||||
|
for: 1m
|
||||||
|
labels:
|
||||||
|
severity: critical
|
||||||
|
annotations:
|
||||||
|
summary: "High 5xx error rate"
|
||||||
|
|
||||||
|
- alert: HighMemoryUsage
|
||||||
|
expr: (jvm_memory_used_bytes{area="heap"} / jvm_memory_max_bytes{area="heap"}) > 0.9
|
||||||
|
for: 2m
|
||||||
|
labels:
|
||||||
|
severity: warning
|
||||||
|
annotations:
|
||||||
|
summary: "JVM heap usage > 90%"
|
||||||
|
|
||||||
|
- alert: ConnectionPoolExhausted
|
||||||
|
expr: (hikaricp_connections_active / hikaricp_connections_max) > 0.9
|
||||||
|
for: 1m
|
||||||
|
labels:
|
||||||
|
severity: critical
|
||||||
|
annotations:
|
||||||
|
summary: "Connection pool almost full"
|
||||||
|
|
||||||
|
- alert: SlowEndpoint
|
||||||
|
expr: histogram_quantile(0.95, sum(rate(http_server_requests_seconds_bucket[5m])) by (le, uri)) > 2
|
||||||
|
for: 5m
|
||||||
|
labels:
|
||||||
|
severity: warning
|
||||||
|
annotations:
|
||||||
|
summary: "Endpoint p95 latency > 2s"
|
||||||
|
```
|
||||||
|
|
||||||
|
Добавь в `prometheus.yml`:
|
||||||
|
```yaml
|
||||||
|
rule_files:
|
||||||
|
- /etc/prometheus/prometheus-alerts.yml
|
||||||
|
```
|
||||||
|
|
||||||
|
## Best Practices
|
||||||
|
|
||||||
|
1. **Регулярно проверяй метрики** — открывай Grafana хотя бы раз в день
|
||||||
|
2. **Настрой алерты** — получай уведомления о проблемах
|
||||||
|
3. **Анализируй тренды** — сравнивай метрики по неделям
|
||||||
|
4. **Документируй инциденты** — записывай что пошло не так и как исправил
|
||||||
|
5. **Тестируй под нагрузкой** — используй JMeter/Gatling + метрики для нагрузочного тестирования
|
||||||
|
6. **Не игнорируй warning** — маленькие проблемы перерастают в большие
|
||||||
|
|
||||||

# gradlew start up script for POSIX generated by Gradle.
|
||||||
|
#
|
||||||
|
# Important for running:
|
||||||
|
#
|
||||||
|
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||||
|
# noncompliant, but you have some other compliant shell such as ksh or
|
||||||
|
# bash, then to run this script, type that shell name before the whole
|
||||||
|
# command line, like:
|
||||||
|
#
|
||||||
|
# ksh gradlew
|
||||||
|
#
|
||||||
|
# Busybox and similar reduced shells will NOT work, because this script
|
||||||
|
# requires all of these POSIX shell features:
|
||||||
|
# * functions;
|
||||||
|
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||||
|
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||||
|
# * compound commands having a testable exit status, especially «case»;
|
||||||
|
# * various built-in commands including «command», «set», and «ulimit».
|
||||||
|
#
|
||||||
|
# Important for patching:
|
||||||
|
#
|
||||||
|
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||||
|
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||||
|
#
|
||||||
|
# The "traditional" practice of packing multiple parameters into a
|
||||||
|
# space-separated string is a well documented source of bugs and security
|
||||||
|
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||||
|
# options in "$@", and eventually passing that to Java.
|
||||||
|
#
|
||||||
|
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||||
|
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||||
|
# see the in-line comments for details.
|
||||||
|
#
|
||||||
|
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||||
|
# Darwin, MinGW, and NonStop.
|
||||||
|
#
|
||||||
|
# (3) This script is generated from the Groovy template
|
||||||
|
# https://github.com/gradle/gradle/blob/3d91ce3b8caaf77ad09f381f43615b715b53f72c/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
