logging

问题 Is it an easy way to write logs into a text file too? I need a crash log to analyse when something went wrong. But I already use println al around in the code. 回答1: Use String.writeToFile(<#path: String#>, atomically: <#Bool#>, encoding: <#NSStringEncoding#>, error: <#NSErrorPointer#>) You could add this: #if DEBUG func println(s:String) { var error:NSError? = nil let path = "/Users/<me>/dump.txt" var dump = String(contentsOfFile: path, encoding: NSUTF8StringEncoding, error: nil)! "\(dump)\n\

问题 I work a lot with network and serial communications software, so it is often necessary for me to have code to display or log hex dumps of data packets. Every time I do this, I write yet another hex-dump routine from scratch. I'm about to do so again, but figured I'd ask here: Is there any good free hex dump code for C++ out there somewhere? Features I'd like: N bytes per line (where N is somehow configurable) optional ASCII/UTF8 dump alongside the hex configurable indentation, per-line

问题 Due to application requirements, I have an externally accessible CouchDB instance. I would like to see what IP addresses are attempting to authenticate with my database. By checking the couchdb.log file, I can see failed authentication attempts. They look similar to this. [Mon, 29 Sep 2014 13:43:32 GMT] [info] [<0.28472.7>] 127.0.0.1 - - GET /offline_master/ 401 However, no matter where I connect from, it seems that the IP address that is logged is always 127.0.0.1. Am I mis-understanding how

问题 Currently, I have the following architecuture in kubernetes: In a pod, a service and a sidecar container (called logger ) is running. The services writes to a file, the sidecar container reads that file and writes it to stdout. A fluentd daemonset is configured to read the output (which is collected in a file in /var/log/containers/*_logger-*.log , which is a link to another file (the latest file since the last file rotation, to the older files, no link points). Always 3 log messages belong

问题 I want to display all values set in MDC in log file in json format in log4j 1.2 version. This is third party's log4j.properties file I'm modifying so I can't change anything other than this log4j.properties file, I mean I can't add any other dependency like to help this log4j to support MDC and json format. I can print values using %X{PARAMETER_NAME} but can't get all MDC values at once. log4j.appender.ReportsExecutionLog = org.apache.log4j.RollingFileAppender log4j.appender

问题 I have this command: "C:/Path/to/maven/bin/mvn" tomcat:run-war -f D:/Path/to/pomProject/pom.xml -Dmaven.tomcat.port=8282 -s "D:/Path/to/maven/settings/settings.xml" I know --log-file to redirect my logs to some file. Now, I have a Listener Applications for Logs, in the Port 514 in another Host... Host 192.168.97.100 Port 514 How redirect using Maven? Is it possible or another alternative? 来源： https://stackoverflow.com/questions/58628509/maven-redirect-output-logs-logging-to-remote-server
