问题 Is there a way to have Sass print out a variable to the terminal? 回答1: Sass 3.3 and older There are 2 error related directives: @debug The @debug directive prints the value of a SassScript expression to the standard error output stream. @debug 10em + 12em; outputs: Line 1 DEBUG: 22em @warn The @warn directive prints the value of a SassScript expression to the standard error output stream. It's useful for libraries that need to warn users of deprecations or recovering from minor mixin usage

问题 I want to send logs from a Java app to ElasticSearch, and the conventional approach seems to be to set up Logstash on the server running the app, and have logstash parse the log files (with regex...!) and load them into ElasticSearch. Is there a reason it's done this way, rather than just setting up log4J (or logback) to log things in the desired format directly into a log collector that can then be shipped to ElasticSearch asynchronously? It seems crazy to me to have to fiddle with grok

问题 I want to parse NGINX error logs. However, there seems to be no documentation at all, concerning the used log format. While the meaning of some fields like the data is pretty obvious, some are not at all. In addition, I cannot be sure that my parser is complete if I do not have a documentation of all the possible fields. Since it seems you can change the access log format, but not that of the error log, I really have no idea how to get the information I need. Does anyone know of such a

问题 I'm trying to figure out how to use the logger with rails 3. I need to log to a file not have it in the console, but I just can't figure out how to set it up and then, how to write something to that log. I tried the rails docs but they didn't really make it clear. 回答1: By default, Rails should be logging to an environment-specific log file in your project's log directory. It will be called either test.log , development.log , or production.log depending on which environment you're running in.

问题 I have an application which uses JDK Logging with a logging.properties file which configures a number of older log-file via java.util.logging.FileHandler.count. At certain points in the application I would like to trigger a manual rollover of the logfile to have a new logfile started, e.g. before a scheduled activity starts. Is this possible with JDK Logging? In Log4j I am using the following, however in this case I would like to use JDK Logging! Logger logger = Logger.getRootLogger();

问题 In relation to my other question "What’s the best way to audit log DELETEs?". What's the PostgreSQL equivalent of CONTEXT_INFO? [EDIT] I want to log deletes using trigger, but since i'm not using the database user as my app's logical user, I cannot log the CURRENT_USER from the trigger code as the user who deleted the record. But for INSERT and UPDATE it is possible to log the record changes from trigger since you can just add a user field in the record, say inserted_by and last_updated_by,
