What is observability? Everything a beginner needs to know

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.

What are the network devices that Zabbix 3.0 monitors?

What are the network devices that Zabbix 3.0 monitors?

Introduction to SNMP 1 Overview of SNMP SNMP has developed to become the most widely used network management protocol. The currently applied versions mainly include SNMPv1, SNMPv2c and SNMPv3. 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). NMS can generate commands and receive notification information. There must be at least one in the network management

How to install and use Fiddler

How to install and use Fiddler

Introduction to Fiddler ① Fiddler is a powerful packet capture tool. Its principle is to work in the form of a web proxy server. 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

Solution to USG address mapping problem

Solution to USG address mapping problem

The USG6000 series firewall I use, the situation overview: 1. The internal network address business of accessing the server from the internal network address is normal 2. The public network address business mapped by the external network access server is normal 3. The solution to the exception of the public network address business of the internal network address access server : 1. Whether the firewall server mapping policy is written properly. Do not join the security domain. 2. UNtrust in the security policy -> trust whether to allow access to the server address 3. In the NAT policy, source NAT adds trust to the trust zone to allow normal access to the server address. I failed in the third item, so it caused the intranet The public network address mapped by the address access server is abnormal. Attached is a picture

What is the Turla organization?

What is the Turla organization?

Turla Organization Overview Turla, also known as Snake, Uroburos, Waterbug, WhiteBear. After being disclosed by GData in 2014, Kaspersky, Symantec, and ESET continued to track and analyze the organization. The malicious files used by the group were compiled as far back as 2011. Through comparison of codes and functions, it can be traced back to 2006 that a malicious file named Agent.BTZ was detected to be associated with this organization. Therefore, it can be inferred that the organization has begun to carry out attacks as early as 2006. The Turla organization uses rootkit technology to monitor computers and complete data theft.

How to use Performance to monitor front-end performance

How to use Performance to monitor front-end performance

Performance.nowPerformance is an API that is indispensable for front-end performance monitoring. It is best to use it after the page is fully loaded, because many values ​​must be obtained after the page is fully loaded. The simplest way is to read various data in the window.onload event. The performance.now() method returns a DOMHighResTimeStamp accurate to milliseconds. According to MDN: This timestamp is not actually highly accurate. In order to reduce security threats like Specter, various browsers round off the value of this type to varying degrees. (Firefox starting with Firefox59
