Prometheus监控Canal
Prometheus监控Canal
一、背景
简单记录下，使用Prometheus对Canal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
4、canal原始指标解释
