前言：
现在都是使用K8S环境，所以集群内我们会使用prometheus-operator来快速部署prometheus，grafana,alertmanger三大件。下面演示一下如何通过oracle-exporter,mysql-exporter的方式添加oracle,mysql的数据库监控；
1.oracle-exporter,mysql-exporter的部署安装
部署文件已经放到个人码云上，只需要在values.yaml文件更改自己的数据库信息就可以完成部署了。
2.oracle-exporter,mysql-exporter部署完成后，需要在prometheus上添加配置信息；
如果exporter都部署完成了，需要在prometheus-operator的values.yaml文件添加以下配置信息：
additionalScrapeConfigs:
- job_name: monitoring/oracle-export/0
scrape_interval: 30s
scrape_timeout: 10s
metrics_path: /metrics
scheme: http
static_configs:
- targets: ["oracle-export.monitoring:9161"]
- job_name: monitoring/mysql-export/0
scrape_interval: 30s
scrape_timeout: 10s
metrics_path: /metrics
scheme: http
static_configs:
- targets: ["mysql-exporter-prometheus-mysql-exporter.monitoring:9104"]
然后更新prometheus-operator然后就可以看到oracle和mysqld的监控信息了
3.添加oracle,mysql的grafana监控模板

The query cache has huge scalability problems in that only one thread can do an operation in the query cache at the same time.\\\n***InnoDB Dictionary Size***: The data dictionary is InnoDB ‘s internal catalog of tables. InnoDB stores the data dictionary on disk, and loads entries into memory while the server is running.\\\n***InnoDB Log Buffer Size***: The MySQL InnoDB log buffer allows transactions to run without having to write the log to disk before the transactions commit.",

This serialization is true not only for SELECTs, but also for INSERT/UPDATE/DELETE.\n\nThis also means that the larger the `query_cache_size` is set to, the slower those operations become. In concurrent environments, the MySQL Query Cache quickly becomes a contention point, decreasing performance. MariaDB and AWS Aurora have done work to try and eliminate the query cache contention in their flavors of MySQL, while MySQL 8.0 has eliminated the query cache feature.\n\nThe recommended settings for most environments is to set:\n ``query_cache_type=0``\n ``query_cache_size=0``\n\nNote that while you can dynamically change these values, to completely remove the contention point you have to restart the database.",

"description": "**MySQL Query Cache Activity**\n\nThe query cache has huge scalability problems in that only one thread can do an operation in the query cache at the same time. This serialization is true not only for SELECTs, but also for INSERT/UPDATE/DELETE.\n\nThis also means that the larger the `query_cache_size` is set to, the slower those operations become. In concurrent environments, the MySQL Query Cache quickly becomes a contention point, decreasing performance. MariaDB and AWS Aurora have done work to try and eliminate the query cache contention in their flavors of MySQL, while MySQL 8.0 has eliminated the query cache feature.\n\nThe recommended settings for most environments is to set:\n``query_cache_type=0``\n``query_cache_size=0``\n\nNote that while you can dynamically change these values, to completely remove the contention point you have to restart the database.",

4.添加prometheus的监控告警规则
假定一个oracle的数据库告警记录
将labels中的app跟prometheus配置文件添加进去进行绑定，后续的所有告警都指定app同样的名称，这样后续所有中间件的告警规则就可以看到了 prometheus-operator
ruleSelector:
matchLabels:
app: prometheus-operator
最后告警规则就出现了，如下图所示：
