Prometheus + grafana 的监控平台部署

一、Prometheus安装

tar -zxvf prometheus-2.44.0.linux-amd64.tar.gz -C /opt/module/
sudo chown -R bigdata:bigdata /opt/module/prometheus-2.44.0.linux-amd64
mv /opt/module/prometheus-2.44.0.linux-amd64 /opt/module/prometheus-2.44.0
ln -s /opt/module/prometheus-2.44.0 /usr/local/prometheus

1.1 修改配置文件

vim /opt/module/prometheus-2.44.0/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=` to any timeseries scraped from this config.
  - job_name: "prometheus"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["node1:9090"]

  - job_name: 'pushgateway'
    static_configs:
    - targets: ["node1:9091"]
      labels:
        instance: pushgateway

  - job_name: 'node exporter'
    static_configs:
    - targets: ['node1:9100', 'node2:9100', 'node3:9100', 'node4:9100']

  - job_name: 'kafka_exporter'
    static_configs:
    - targets: ["node1:9308"]

  - job_name: 'clickhouse-cluster'
    static_configs:
    - targets: ['node4:9363','node3:9363','node2:9363','node1:9363']
