Prometheus监控ElasticSearch

这里只是对prometheus监控ES的配置过程做个记录，方便以后查阅。

1.安装elasticsearch-prometheus-exporter

[admin@haifly-bj-es2 ~]$ ./elasticsearch-6.5.3/bin/elasticsearch-plugin install -b https://github.com/vvanholl/elasticsearch-prometheus-exporter/releases/download/6.5.3.0/prometheus-exporter-6.5.3.0.zip

输出如下：

安装完别忘了重启es

2.安装并启动export（可选）

[admin@haifly-bj-es2 ~]$ tar xf elasticsearch_exporter-1.1.0rc1.linux-amd64.tar.gz
[admin@haifly-bj-es2 ~]$ mv -f elasticsearch_exporter-1.1.0rc1 elasticsearch_exporter
[admin@haifly-bj-es2 ~]$ /work/admin/elasticsearch_exporter/elasticsearch_exporter --web.listen-address=":9114" --es.uri="http://192.168.6.217:9200" --es.all

3.prometheus配置

- job_name: 'es'
  static_configs:
  - targets: ['192.168.7.206:9100']
    labels: {cluster: 'product',type: 'basic',env: 'es',job: 'es1',export: 'es'}
  - targets: ['192.168.7.206:9114']
    labels: {cluster: 'product',type: 'basic',env: 'es',job: 'es1',export: 'elasticsearch_exporter'}
  - targets: ['192.168.6.217:9100']
    labels: {cluster: 'product',type: 'basic',env: 'es',job: 'es2',export: 'es'}
  - targets: ['192.168.6.217:9114']
    labels: {cluster: 'product',type: 'basic',env: 'es',job: 'es2',export: 'elasticsearch_exporter'}
  - targets: ['192.168.3.96:9100']
    labels: {cluster: 'product',type: 'basic',env: 'es',job: 'es3',export: 'es'}
  - targets: ['192.168.3.96:9114']
    labels: {cluster: 'product',type: 'basic',env: 'es',job: 'es3',export: 'elasticsearch_exporter'}

- job_name: 'elasticsearch'
  metrics_path: "/_prometheus/metrics"
  static_configs:
  - targets: ['192.168.7.206:9200']
    labels: {cluster: 'product',type: 'middle',env: 'es',job: 'es1',export: 'elasticsearch'}
  - targets: ['192.168.6.217:9200']
    labels: {cluster: 'product',type: 'middle',env: 'es',job: 'es2',export: 'elasticsearch'}
  - targets: ['192.168.3.96:9200']
    labels: {cluster: 'product',type: 'middle',env: 'es',job: 'es3',export: 'elasticsearch'}
  - targets: ['192.168.7.210:9200']
    labels: {cluster: 'product',type: 'middle',env: 'es-work',job: 'es-work',export: 'elasticsearch'}

重启prometheus

如果开启了api管理功能，可以如下方式热加载配置

1	curl -X POST http://127.0.0.1:9090/-/reload

4.grafana出图

推荐使用4358、266、2322

效果如下

上图面板经过一定的修改可能略有不同，仅供参考
