什么是云性能监控？

云性能监控是指定期跟踪和分析您的云基础设施。您应该关注性能，它还涉及到您的服务和应用程序。 

In cloud performance monitoring, you look at data from multiple sources. After doing that, you should look for solutions to problems that may affect security, performance, and availability/uptime.  

云性能监控需要实时数据聚合。这对于利用资源、识别瓶颈和寻找成本效益机会至关重要。

您应该主动监控云性能，以便在用户受到影响之前发现并解决问题。这对服务交付也至关重要。

虽然云性能监控和云安全监控相辅相成，但它们并不相同。以下是云性能监控的一些主要组成部分：

• Cloud performance monitoring prioritizes detecting and mitigating security risks (e.g. unauthorized access and data breaches). 
• Cloud performance monitoring looks at resource utilization and finding bottlenecks, while also measuring responsiveness.
• You must customize cloud monitoring tools to optimize data better. 

Cloud security monitoring, meanwhile, has these characteristics:

• You can generate several alerts with cloud security monitoring, but you need to prioritize and analyze carefully – otherwise, you risk alert fatigue.
• Performance monitoring needs extra tools to address security concerns directly.
• Security monitoring 很重要，但不是为了用户体验和应用程序功能性能的洞察。

你需要对齐 云性能监控 与您的业务目标保持一致，如果希望您的策略有效。确定主要的 关键绩效指标 (KPI) 在实施云性能监控之前，要考虑可靠性、安全性和效率。

云监控工具从网络流量、基础设施、各种指标和应用程序日志中收集数据。 

如果你使用云服务，你必须实施有效的云性能监控。需要考虑的关键绩效指标包括响应时间、资源利用率和网络延迟。

你应该将这些关键绩效指标用于： 

• 云性能优化 
• Outage prevention
• Online experiences
• Bottleneck identification and diagnosis 
• Performance optimization
• Optimizing UX and operations

Start by regularly monitoring resource usage through third-party monitoring tools, cloud provider dashboards, or both. You should then change cloud figurations with cost reduction and performance optimization in mind; be sure not to disrupt how everything runs, though.

You need to monitor cloud usage regularly thereafter, reviewing configurations further when necessary. Doing this may help you get more out of your resources; for example, you should down your virtual machines in off-peak hours if they’re idle for most of the day.

在为您的需求选择云监控工具时，请考虑以下因素： 

• Cost: What’s your budget; can you use a free/open source version, or do you need a subscription?
• 可扩展性：该工具能否满足不断扩展的基础设施日益增长的需求？
• Ease of Use: What’s the learning curve, and what is its interface like?
• 集成：选择一个可以与 AWS、Azure 或您使用的任何云软件集成的工具。
• Metrics: Does the tool have the performance data that you need to track? 

热门云监控工具

• Amazon CloudWatch：如果您需要监控 AWS 上的资源，请使用此工具。
• Site24x7：如果您需要在 AWS、GCP 和 Azure 上进行监控，请使用此工具。
• Zabbix：开源工具，可能需要更多的技术专业知识，但如果您具备这些技能，则非常有用。
