    What is observability? Everything a beginner needs to know
    The term observability originates from the engineering field and has become increasingly popular in the software development field in recent years. Simply put, observability is the ability to understand the internal state of a system based on external outputs. IBM defines observability as: Generally, observability refers to the degree to which the internal state or condition of a complex system can be understood based on knowledge of its external output. The more observable the system is, the faster and more accurate the process of locating the root cause of a performance issue can be without the need for additional testing or coding. In cloud computing, observability also refers to software tools and practices that aggregate, correlate, and analyze data from distributed application systems and the infrastructure that supports their operation in order to more effectively monitor, troubleshoot, and debug application systems. , thereby achieving customer experience optimization and service level agreement

  • Google's case study on building static code analysis tools
    Google's case study on building static code analysis tools
    Software bugs cost developers and software companies a lot of time and money. In 2014, for example, a ("gotofail") bug in the widely used SSL protocol implementation caused invalid SSL certificates to be accepted, and another bug related to date formatting caused widespread service outages on Twitter. Such errors can often be detected by static analysis. In fact, they can be quickly identified during the reading of code or documentation, and the final reality is that the situation still occurs in the production environment. Previous work has well reported experiences in applying bug detection tools to software development. But while there are so many success stories among developers using static analysis tools, there are still reasons why engineers are not always willing to use static analysis tools.

The main differences between the versions are in the definition of information, the operation of communication protocols and the security mechanism. At the same time, two extensions of SNMP applications, remote network monitoring RMON (Remote Network Monitoring) and RMON2, have also appeared. From the perspective of the physical layer, using SNMP to manage the network should include: network management station (NMS), agent (Agent), and proxy server (proxy).

The proxy address used is: 127.0.0.1, port The default is 8888, we can also modify it through settings. ②Proxy is to set up a barrier between the client and the server. After the client sends the request data first, the proxy server will intercept the data packet, and the proxy server will intercept the data packet. The proxy server then pretends to be a client and sends data to the server; similarly, the server will return the response data, and the proxy server will also intercept the data and return it to the client. ③Fiddler can capture support
