springboot2+exporter+prometheus+grafana搭建監控體系
step1 編寫springboot2程序
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>io.micrometer</groupId> <artifactId>micrometer-registry-prometheus</artifactId> </dependency>
step2 node_exporter安裝:
在https://github.com/prometheus/node_exporter/releases找到最新的壓縮包,然後wget,解壓tar -zxvf到本地。
執行:./mysqld_exporter
step3 mysql_exporter安裝
在https://github.com/prometheus/mysqld_exporter找到最新的壓縮包,然後wget,解壓tar -zxvf到本地。
詳細安裝參考官方文檔。
1 mysql創建新用戶:
CREATE USER ‘exporter‘@‘localhost‘ IDENTIFIED BY ‘XXXXXXXX‘ WITH MAX_USER_CONNECTIONS 3;
2設置環境變量:
export DATA_SOURCE_NAME=‘user:password@(hostname:3306)/‘
3 啟動
./mysqld_exporter
先確保mysql啟動和有my.cnf文件,然後執行:./mysqld_exporter
step4 prometheus安裝和配置
下載最新版的prometheus安裝和配置:wget https://github.com/prometheus/prometheus/releases/download/v2.8.0-rc.0/prometheus-2.8.0-rc.0.darwin-amd64.tar.gz
先配置prometheus.yml文件,需要定義一系列job和targets以連接到step1-3中的組件。
prometheus.yml 參考:
# my global config
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
# - alertmanager:9093
# Load rules once and periodically evaluate them according to the global ‘evaluation_interval‘.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it‘s Prometheus itself.
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: ‘prometheus‘
# metrics_path defaults to ‘/metrics‘
# scheme defaults to ‘http‘.
static_configs:
- targets: [‘localhost:9090‘]
- job_name: ‘node‘
static_configs:
- targets: [‘localhost:9100‘]
- job_name: ‘spring-boot‘
metrics_path: /prometheus
static_configs:
- targets: [‘localhost:8080‘]
- job_name: ‘mysql-monitor‘
static_configs:
- targets: [‘localhost:9104‘]
編寫好之後啟動prometheus
./prometheus --config.file=prometheus.yml
訪問localhost:9090,查看targets看配置的監控是否正確:
step5 grafana安裝
wget https://dl.grafana.com/oss/release/grafana-6.0.1.darwin-amd64.tar.gz,
tar -zxvf grafana-6.0.1.darwin-amd64.tar.gz
./bin/grafana-server web
step6 自定義panel:jvm,mysql,cpu相關指數
