microservice tracing

ScaleWhen we have a deep understanding of this architecture, we will find that when the project scale becomes large, there is a very big bottleneck, that is, the data storage system. Especially relational databases. Of course, although more than 90% of the current systems use relational databases, the expansion of the project scale is not a norm after all. Therefore, the existence of such bottlenecks will not be too big a problem. In short, the classic application system structure can be app

Spent some time on bidirectional path tracing (BPT) in pbrt. at least parts of the Code, I had to do it by try and error. debugging is a pain. The implementation may Still be wrong in some details, but generally it performs much better than path (PT) Tracing built-in pbrt. Here is the Cornell box scene rendered with path tracing. Note the area lightPointing

Microsoft recently released svcperf, an end-to-end Windows event tracing (ETW)-based tracing viewer for configuration-based tracing. You can use this tool to view ETL files or track sessions in real time, and create custom queries. This end-to-end tracing analysis tool is based on LINQ over traces (TX) and can be use

WCF applicationsProgramLogs can be recorded during conversion or at the service layer, or trace relatedCodeOutput logs. The tracing level is configurable. The default configuration is recorded only at the severity level. Traceviewer can open

Does PHP have a function tracing tool, for example, to request an API, I want to know which methods are called by this API and the files associated with the called files, does PHP have function tracing tools in this way? For example, if you want to request an API and want to know the methods of all the files called by this API, and the files associated with the called files, you can trace them recursively.

Ray tracing is one of the most famous techniques in the field of graphics, the first of which is the point of view (camera, eye) passing through the center of the pixel, emitting a ray, the main ray (secondary light refers to the light emitted from the surface of the object, such as reflection or refraction). This step looks relatively simple, but still involves some details and concepts that need to be clarified.My system of learning these things is

In my OS x programming of late, one debugging technique I thought wocould be handy is the ability log and trace Objective-C messages sent. it turns out this is not only possible, but quite easy. however my journey to this easy answer was quite long and took me deep into the Objective-C rabbit hole. Apple's Cocoa programing environment is based on Objective-C, a Smalltalk-influenced object oriented extension to C. objC is a dynamic language, meaning method CILS ("sending messages" in true OO parl

Generally, we use an event probe to track the running status of SQL Server. Sometimes we also need to regularly track the running status of SQL Server within a certain period of time, because the event probe does not support scheduling, you should look for a method that is suitable for starting a trail by setting the job, this article describes the use of T-SQL statements to enable the trail is suitable for this demand. 　　1. Use a script to start and Set Tra
