libraries will be introduced concretely. Logging is just the first step in effectively using the log, and more importantly, how to process and analyze the logs generated by the program's runtime. A typical scenario involves triggering a notification mechanism, such as a message or SMS notification, when the log contains records that meet certain conditions, and can quickly locate potential source of problem when an error occurs in the program's operation. This ability to process and analyze is

LOG4J can be configured by using a configuration file.The configuration steps are as follows: 1. Define the Log component loggerEach logger can have one or more appender, each appender representing the output destination of a log, such as the console or a file.The syntax for configuring root logger is:Log4j.rootlogger=[priority],appendername,appendername,...-The syntax for configuring a custom

recommend using the Apache Commons Logging API because its complexity does not give you other features.Log OverviewThe log4j and Java Logging APIs use similar design and usage patterns (shown in Figure 1 and listing 1). The message is created first and then passed to a log object with a specific priority. The purpose and format of these messages are determined by the output handler and its layout.Listing 1. Instantiation and use of log objects Import Org.apache.log4j.Logger; public class MyCl

In this article, I will give an example based on the two rolling methods. At the time of writing this article, log4net has been released to version 1.2.11 (the new version has not been released yet ).

Introduction to the python logging Module Use python to write programs, and sometimes use the log system. Especially for dynamic languages like python, many errors can only be found during running. A good log system is very important to Python programs. The simplest solution is to directly use print to output the running information. However, this is too simple and there is no grading function. If you want to remove the running information for debugging during release, you have to find all the p

you want to wait for the end of a thread, you need to call the join () method.When you run the above code, you will get the following output:Thread-10Thread-22Thread-34Thread-46Thread-58Of course, normally you do not want the output to be printed to the standard output. If we do this unfortunately, the final display will be messy. You should use the Python logging module. It is thread-safe and performs well. Let's use the logging module to modify the above example and name our thread. The c
