Summary
With the development of modern micro-services architecture, positioning system failure and rapid recovery faces many challenges, building a service detectable, help online support team time control applications operating conditions more and more important. Availability of this share will explain how to make ASP .NET Core application with the perfect blend of modern cloud infrastructure, improve service detectability, online protection system.
The evolutionary history of technical architecture
- Monomers architecture
- Service oriented architecture (SOA)
- Micro Services Architecture
- Service Mesh
Architectural challenges brought about by evolution
- Application of the demolition of more
- More and more complex topologies
- Fault location difficult
Which may need to be applied to detect scene
- Automatic fault isolation
- Fault location investigation
- Service availability detection
- Service Performance Test
.NET Core detectability support
- Logging framework (Logging)
- Diagnostic Framework (Diagnostics)
- Health check frame (HealthChecks)
.NET Core logging framework - Microsoft.Extensions.Logging
Logging framework features of .NET Core
.NET Core logging framework applicable scene
- User request logs
- Exception logging
- Call logs external interface
- Warning output debugging of complex components
Log tips
.NET Core diagnostic framework - System.Diagnostics
The main categories:
System.Diagnostics.DiagnosticListener
System.Diagnostics.DiagnosticSource
Diagnostic framework features of .NET Core
- Publish and subscribe event design model
- It supports any object tracking
- Support for dynamic switch
- Support listening screening
Diagnostic Framework .NET Core of application scenarios
- When logging component can not meet demand
- When expectations for the implementation of the internal components of the tracking process
- When the desired specific event occurs, modify the external component object
Applications of Diagnostic Framework .NET Core
- HttpClient
- MySql.Data
- CAP Components
- SkyWalking .NET
ASP .NET Core health check frame - Microsoft.AspNetCore.Diagnostics.HealthChecks
Health Check framework features of ASP .NET Core
ASP .NET Core Framework application scenario of health checks
- 检查应用端口是否可访问
- 检查应用依赖服务是否可访问
- 检查应用内组件是否正常工作
与云服务融合实现故障隔离
- 负载均衡的健康检查
- K8S 的 LivenessProbe
与监控系统打通
- 监控系统探针访问健康检查接口
- 主动推送健康检查结果到监控系统
愿景
持续提高开发者的幸福感
