Exporters | 安装elasticsearch_exporter

一、下载linux版本的elasticsearch_exporter

下载地址：https://github.com/prometheus-community/elasticsearch_exporter

wget https://github.com/prometheus-community/elasticsearch_exporter/releases/download/v1.5.0/elasticsearch_exporter-1.5.0.linux-amd64.tar.gz

二、解压安装包

tar -zxf elasticsearch_exporter-1.5.0.linux-amd64.tar.gz -C /data
mv /data/elasticsearch_exporter-* /data/elasticsearch_exporter
chown -R root.root /data/elasticsearch_exporter

三、创建启动服务文件

vim /usr/lib/systemd/system/elasticsearch_exporter.service
[Unit]
Description=Elasticsearch Exporter
Wants=network-online.target
After=network-online.target


[Service]
User=root
Group=root
Type=simple
ExecStart=/data/es_exporter/elasticsearch_exporter \
          --es.all \
          --es.aliases \
          --es.cluster_settings \
          --es.indices \
          --es.indices_settings \
          --es.shards \
          --es.snapshots \
          --web.listen-address ":9114" \
          --es.ssl-skip-verify \
          --es.uri http://rio:ee012e12340a177f60766d35baa81955d@192.158.134.3:9200 \
          --es.timeout 20s \
          --es.clusterinfo.interval 5m
Restart=on-failure


[Install]
WantedBy=multi-user.target

四、启动服务

systemctl daemon-reload
systemctl enable --now elasticsearch_exporter
systemctl status elasticsearch_exporter

五、查看端口和服务

ss -nltp|grep 9114

六、prometheus-server配置

prometheus.yml配置

scrape_configs:
  - job_name: 'elasticsearch-exporter'
    file_sd_configs:
    - files:
      - targets/elasticsearch*.yaml
      refresh_interval: 2m
    relabel_configs:
      - source_labels: [ '__address__' ]
        target_label: 'instance'
        regex: "(.*):.*"
        replacement: $1

elasticsearch_exporter.yaml

[root@test targets]# cat elasticsearch_exporter.yaml
- targets:
  - 192.158.134.8:9114
  - 192.158.134.9:9114
  - 192.158.134.11:9114
  labels:
    app: "elasticsearch-server"
    job: "elasticsearch-server"

七、动态重启配置文件

kill -HUP `pgrep prometheus`
