Key performance indicators (KPIs) of cloud monitoring help evaluate the health, performance, and reliability of cloud resources. Here are the main KPIs with examples:

  1. Availability/Uptime: Measures the percentage of time a service or resource is operational.

    • Example: A web application should maintain 99.9% uptime; monitoring tools track outages.

  2. Latency: Tracks the response time of services or APIs.

    • Example: A database query should return results within 200ms; high latency may indicate performance issues.

  3. Error Rate: Counts failed requests or transactions.

    • Example: An API with a 1% error rate may need investigation for bugs or overload.

  4. Throughput: Measures data processed per unit of time.

    • Example: A storage service handling 1TB of data transfers per hour.

  5. Resource Utilization: Monitors CPU, memory, disk, and network usage.

    • Example: A virtual machine (VM) using 90% CPU consistently may require scaling.

  6. Incident Response Time: Tracks how quickly issues are detected and resolved.

    • Example: A monitoring system alerts within 1 minute of a server crash.

For cloud monitoring, Tencent Cloud Monitoring (Cloud Monitor) provides real-time metrics, alerts, and dashboards to track these KPIs, ensuring optimal performance and reliability.
