docker-compose.yml clickhouse metrics prometheus

• 1. docker-compose.yml clickhouse metrics prometheus
• • 1.1. prometheus 与 pushgateway 的区别
  • 1.2. tree
  • 1.3. config.xml
  • 1.4. docker-compose.yml
  • 1.5. prometheus.yml
  • 1.6. restart.sh

• prometheus 是主动抓取方，一般用于需要主动采集的软件，例如 clickhouse。在配置文件 prometheus.yml 中填入 clickhouse 后会主动抓取相应 /metrics 的 metrics。
• pushgateway 是被动接收方，一般用于某些软件主动汇报 metrics 的情况，例如 Flink。在 Flink 配置文件中引入 jar 包并填入 pushgateway 的地址和端口即可。

搞清楚这两个的区别非常有助于了解下面的配置。
