CentOS7 prometheus +node_exporter+Grafana 配置篇（原创）

一、配置prometheus

1、修改配置文件

[root@mongodb05 cfg]# cat prometheus.yml
# 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: mongodb05
    static_configs:
    - targets: ['172.16.102.15:9100']

 

监控多个mongodb服务器

- targets 包含多个ip

2、检查配置文件

# promtool check config /app/prometheus/config/prometheus.yml 
Checking /app/prometheus/config/prometheus.yml
  SUCCESS: 0 rule files found

3、重启prometheus

关闭后，使用下面方式开启，并记下日志

/u01/soft/prometheus/bin/prometheus --config.file=/u01/soft/prometheus/cfg/prometheus.yml --storage.tsdb.path=/u01/soft/prometheus/data > prometheus.log 2>&1 &
