expect1.1 2. dm_exporter工具配置文件
调整application.yml
新增dmhs的相关属性注意enableType类型 需要区分源端以及目的端

1. 添加主机配置 prometheus.yml
[rootZabbbix prometheus-2.35.0]# vim prometheus.yml# my global config
global:scrape_interval: 1m # Set the scrape interval to every 15 seconds. Default is every 1 minute.evaluation_interval: 1m # Evaluate rules every 15 seconds. The default is every 1 minute.scrape_timeout: 1m # scrape_timeout is set to the global default (10s).# Alertmanager configuration
alerting:alertmanagers:- static_configs:- targets:- 127.0.0.1:9093# Load rules once and periodically evaluate them according to the global evaluation_interval.
rule_files:- rules/*.yml# - rules/*_alerts.yml# A scrape configuration containing exactly one endpoint to scrape:
# Here its Prometheus itself.
scrape_configs:# The job name is added as a label jobjob_name to any timeseries scraped from this config.- job_name: prometheusstatic_configs:- targets: [localhost:9090]- job_name: dmdbms_bgoak_dwmetrics_path: /prometheusstatic_configs:- targets: [192.63.97.93:9200,192.63.97.94:9200]labels:cluster_name: 办公OAK2. 添加告警规则vim custom_test.yml [rootZabbbix rules]# vim custom_test.yml- alert: 备库重做日志内存堆积过高expr: dmdbms_rapply_sys_task_mem_used 512000000for: 15slabels:severity: 警告annotations:description: 主机{{ $labels.instance }} 备库重做日志内存堆积过高summary: 主机{{ $labels.instance }}:备库重做日志内存堆积过高请确认是否正常- alert: 备库重做日志线程数expr: dmdbms_rapply_sys_task_num 2048for: 15slabels:severity: 警告annotations:description: 主机{{ $labels.instance }} 备库重做日志线程数过高summary: 主机{{ $labels.instance }}:备库重做日志线程数过高请确认是否正常- alert: HS的进程连接异常expr: dmdbms_dmhs_process_is_exit 0for: 15slabels:severity: 警告annotations:description: 主机{{ $labels.instance }} HS的进程连接异常summary: 主机{{ $labels.instance }}:HS的进程连接异常请确认是否正常- alert: HS的checkPointTime超过8hexpr: dmdbms_dmhs_check_point_delay 0 and dmdbms_dmhs_check_point_delay 60*60*8for: 15slabels:severity: 警告annotations:description: 主机{{ $labels.instance }} HS的checkPointTime超过8hsummary: 主机{{ $labels.instance }}:HS的checkPointTime超过8h,请确认是否正常四、修改grafana图表
效果如下 五、报错
安装expect报错 no acceptable cc found in $PATH # 安装gcc的依赖环境
yum install gcc-c
