logging

问题 I'm new to Ruby/Rails programming and still finding my way. I have created a sample web app by following this tutorial. It's working fine. It's using Ruby version 1.9.3 with Rails version 4.0.8. However I would like to implement logging. So I inserted the following lineq into one of my controllers: logger.debug "Hello! I'm a DEBUG message" logger.info "Hello! I'm an INFO message" This produced the following logs: Hello! I'm a DEBUG message Hello! I'm an INFO message That's not too helpful. I

问题 I am confused with the best practice to use in logging. I found by reading that SLF4J removes the coupling between the application and logging API etc. So if i use actor logging, will it not be closely coupled to application?.I have also checked a lot of github codes and i noticed that they only use actor logging and not org.SLF4J.LoggerFactory logging. Why? Some links which i referred SACHA'S BLOG OF PROGRAMMATICALNESS Another Good read stack Overflow -> Checked the last answer Thanks in

问题 I am running my TestNG tests on multiple threads (Appium tests on multiple devices simultaneously) and want to write the test logs on different threads in different files. Here the threads are created automatically before the start of the test flow. So I want to create separate appender and separate logger programatically so that each appender would be attached to its own thread only and then the loggers created in one thread would have the appender created in that thread only. Please let me

问题 At first I displayed the logs in Kibana from the syslog and it worked fine. I set it up according to the documentation. Now I've changed the source of the logs, now it retrieves logs from my web application and although Kibana still displays them kind of correctly, now there're the Tags "_grokparsefailure" which means that there's an error in parsing the logs. The current filter I have: filter { if [type] == "syslog" { grok { match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %

问题 We do a lot of trace logging in our WebSphere application and would like to separate some timing information in a separate log file. Usually we import: import java.util.logging.Level; import java.util.logging.Logger; And then declare: private static final Logger logger = Logger.getLogger(Myclass.class.getName()); And then log: logger.info("now logging..."); What is the simplest way of doing that? 回答1: You can use Apache logging services to create logs outside Websphere Application Server.
