第 14 章 管理和故障排除 管理和故障排除

在前几章中，我们向你介绍了如何为 CockroachDB 平台设计和实施应用程序，以及如何在完全托管的云平台（CockroachDB Dedicated 和 Serverless）上创建 CockroachDB 部署，或者在自己的硬件或公共云上自托管实施。
现在，你已经实施了 CockroachDB 应用程序，CockroachDB 集群也已就位，是时候考虑日常管理和配置任务了，这些任务都是保持 CockroachDB 部署健康、愉快运行所必需的。
我们将把最重要的任务之一--集群优化--留到最后一章，因为该主题足够深入，需要单独成章。
请注意，虽然这些任务中的很多都是自托管部署才需要的，但即使是CockroachDB专用云或无服务器云集群也需要一些细心和关注。选择 CockroachDB Cloud 选项可以大大减少你的管理开销；不过，仍有一些故障排除和配置任务，我们将在本章中介绍。
监测
生产系统需要某种形式的监控软件，以确保系统健康、响应迅速，并收集性能和利用率指标，以便进行长期规划。如果没有监控系统，您可能不知道数据库是否已停止响应请求。此外，您可能无法检测到缓慢移动的性能或容量问题。有了好的监控系统，如果数据库发生故障或出现需要注意的问题，您就会立即得到通知。您将掌握相关指标，从而预测未来的资源需求。
好的监控解决方案应同时支持检测和诊断功能：
-
监控系统会发现问题，并将问题通知相关人员。
-
监控系统将收集足够的信息，以便管理员确定问题的根本原因。
监测系统还可以提供解决工具，帮助纠正问题，并提供预测功能，在问题出现之前预测其苗头。
CockroachDB 无服务器警报
CockroachDB专用集群可以访问警报页面。对于 CockroachDB Serverless（测试版）集群，，当集群的花费上限、突发容量或存储上限达到 50%、75% 和 100%时，所有控制台管理员都会自动收到电子邮件提醒。
您可以对这些警报做出反应，要么提高支出限额以避免资源节流启动时出现性能下降，要么调整工作负载以减少需求--例如，按照 ...
