Prometheus监控Canal

2,804 阅读6分钟

一、背景

简单记录下,使用PrometheusCanal进行监控。

二、实现步骤

1、修改prometheus.yml配置文件

vim /Users/huan/soft/prometheus/prometheus-2.25.0/prometheus.yml

scrape_configs:
  - job_name: 'canal'
    scrape_interval: 30s
    static_configs:
    - targets: ['localhost:11112'] # 端口配置即为canal.properties中的canal.metrics.pull.port
      labels:
        nodename: 'canal'
# 检测刚刚编写的 prometheus.yml 语法是否错误
./promtool check config prometheus.yml

2、启动prometheus

nohup /Users/huan/soft/prometheus/prometheus-2.25.0/prometheus \
--config.file="/Users/huan/soft/prometheus/prometheus-2.25.0/prometheus.yml" \
--web.listen-address="0.0.0.0:9080" \
--web.enable-lifecycle \
--storage.tsdb.retention.time="3d" \
--log.level=debug \
> logs/prometheus.out 2>&1 &

3、查看prometheus是否成功接入canal

canal接入prometheus

4、canal原始指标解释

指标说明单位精度
canal_instance_transactionsinstance接收transactions计数--
canal_instanceinstance基本信息--
canal_instance_subscriptionsinstance订阅数量--
canal_instance_publish_blocking_timeinstance dump线程提交到异步解析队列过程中的阻塞时间(仅parallel解析模式)msns
canal_instance_received_binlog_bytesinstance接收binlog字节数byte-
canal_instance_parser_modeinstance解析模式(是否开启parallel解析)--
canal_instance_client_packetsinstance client请求次数的计数--
canal_instance_client_bytes向instance client发送数据包字节计数byte-
canal_instance_client_empty_batches向instance client发送get接口的空结果计数--
canal_instance_client_request_errorinstance client请求失败计数--
canal_instance_client_request_latencyinstance client请求的响应时间概况--
canal_instance_sink_blocking_timeinstance sink线程put数据至store的阻塞时间msns

canal_instance_put_delaystore put操作events的延时msms
canal_instance_get_delayclient get请求返回events的延时msms
canal_instance_ack_delayclient ack操作释放events的延时msms

5、导入fana图表

导入grafana

图表json数据
