本文介紹SpringBoot如何使用Prometheus配合Grafana監(jiān)控宾符。
1.關(guān)于Prometheus
Prometheus是一個(gè)根據(jù)應(yīng)用的metrics來進(jìn)行監(jiān)控的開源工具。相信很多工程都在使用它來進(jìn)行監(jiān)控,有關(guān)詳細(xì)介紹可以查看官網(wǎng):https://prometheus.io/docs/introduction/overview/驹碍。
2.有關(guān)Grafana
Grafana是一個(gè)開源監(jiān)控利器唤冈,如圖所示伦糯。
從圖中就可以看出來够庙,使用Grafana監(jiān)控很高大上,提供了很多可視化的圖標(biāo)蓝纲。

3.SpringBoot使用Prometheus
3.1 依賴內(nèi)容
在SpringBoot中使用Prometheus其實(shí)很簡單阴孟,不需要配置太多的東西,在pom文件中加入依賴税迷,完整內(nèi)容如下所示永丝。

3.2 配置文件
配置文件中加入配置,這里就只進(jìn)行一些簡單配置翁狐,management.metrics.tags.application屬性是本文配合Grafana的Dashboard設(shè)置的,如下所示:
spring.application.name=springboot_prometheus
management.endpoints.web.exposure.include=*
management.metrics.tags.application=${spring.application.name}
3.3 設(shè)置application
修改啟動(dòng)類凌蔬,如下所示.
@SpringBootApplication
public class Springboot2PrometheusApplication {
public static void main(String[] args) {
SpringApplication.run(Springboot2PrometheusApplication.class, args);
}
@Bean
MeterRegistryCustomizer<MeterRegistry> configurer(
@Value("${spring.application.name}") String applicationName) {
return (registry) -> registry.config().commonTags("application", applicationName);
}
}
SpringBoot項(xiàng)目到這里就配置完成了露懒,啟動(dòng)項(xiàng)目闯冷,訪問http://localhost:8080/actuator/prometheus,如圖所示懈词,可以看到一些度量指標(biāo)蛇耀。
4.Prometheus配置
4.1 配置應(yīng)用
在prometheus配置監(jiān)控我們的SpringBoot應(yīng)用,完整配置如下所示坎弯。
# 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:
- job_name: 'prometheus'
static_configs:
- targets: ['127.0.0.1:9090']
###以下內(nèi)容為SpringBoot應(yīng)用配置
- job_name: 'springboot_prometheus'
scrape_interval: 5s
metrics_path: '/actuator/prometheus'
static_configs:
- targets: ['127.0.0.1:8080']
4.2 啟動(dòng)Prometheus
啟動(dòng)Prometheus纺涤,瀏覽器訪問,查看Prometheus頁面抠忘,如圖所示撩炊。
點(diǎn)擊如圖所示位置,可以查看Prometheus監(jiān)控的應(yīng)用崎脉。
列表中UP的頁面為存活的實(shí)例拧咳,如圖所示。
也可以查看很多指數(shù)囚灼,如下所示骆膝。
5.Grafana配置
啟動(dòng)Grafana,配置Prometheus數(shù)據(jù)源灶体,這里以ID是4701的Doshboard為例(地址:https://grafana.com/dashboards/4701)如圖阅签。
在Grafana內(nèi)點(diǎn)擊如圖所示import按鈕
在如圖所示位置填寫4701,然后點(diǎn)擊load蝎抽。
接下來導(dǎo)入Doshboard政钟。
導(dǎo)入后就可以看到我們的SpringBoot項(xiàng)目對應(yīng)的指標(biāo)圖表了,如圖织中。
