logging

问题 I am using Third Party jars which are appending their own logs in my Java Application's Log file , I don't want to append those third party logs in my log file as it makes log file very clumsy and confusing. The logs are like - `2016-11-03 12:59:41.910 ERROR 13586 --- [ main] o.h.j.i.metamodel.MetadataContext : HHH015011: Unable to locate static metamodel field : org.openskye.domain.TaskQueue_#object_metadata_id 2016-11-03 12:59:41.913 ERROR 13586 --- [ main] o.h.j.i.metamodel.MetadataContext

问题 I feel stupid for asking this, but I've tried a couple things and I'm not sure where to go with it. From the Expect.pm documentation: $object->log_file("filename" | $filehandle | \&coderef | undef) Log session to a file. All characters send to or received from the spawned process are written to the file. I'd like to pass the $filehandle to log_file. However, when I tried this: open (LOG, ">>" .$opt{l}); my $sess = Expect->spawn("telnet $ip"); $sess->log_file(LOG) I get a file named 'LOG' in

问题 I have changed my tomcat logging to use logback.xml instead of util.Logger. I have changed using mentioned steps on https://github.com/grgrzybek/tomcat-slf4j-logback. But now on starting tomcat it is logging every Debug log of tomcat. My logback.xml looks like this: <configuration> <appender name="CONSOLE" class="org.apache.juli.logging.ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern> %d{HH:mm:ss.SSS} %-5level {%thread} [%logger{20}] : %msg%n </pattern> </encoder> </appender>

问题 I would like to log out all my "set -x" output into my syslog file. However, the syslog file has my own custom format. But set -x output does not have formatting. How can I do that? 回答1: If you look at print_cmd.c in the Bash source code, you'll see that the format of set -x output is not configurable. You could trap the DEBUG "signal" to implement your own custom logging, e.g. trap 'logger -p user.debug -t SHELLSCRIPT -- "$BASH_COMMAND" || :' DEBUG to send all commands to syslog with

问题 In my python script, I have this: count = 0 while 1: print count count += 1 I saved this file and I ran it. nohup python count.py >> test.log & $tail -f test.log Nothing shows up when I tail it. 回答1: When you redirect Python output, the stdout stream is opened in buffered mode (instead of line-buffered mode). This means that output is kept in memory until enough lines have been printed before flushing the buffer. To see lines immediately, you need to flush the output stream: import sys count

问题 Note: "output" is meant to meant to data that streams out of php; Eg, stdout, output buffer, data that is returned to an incomming web request. "Output" is not to mean, the value that a functions that returns. Note: "function and statements" is meant to refer to anything that a php script can do ; What could approximately be referred to as a callable, or a statement; Or that PHP Docs refer to as a Language Construct. Or anything else that can in some way, make php output something somewhere.

问题 We are using zend framework 2 for a new application, i would like to have the same logging system of Rails or similar, i would like have a log for each request, is possible to do this in Zend? 回答1: It depends what you want to log. If it is just an access log, you should try to use the webserver's log. The logs from Apache/nginx/IIS etc perform better than you will achieve in your ZF2 app. If you need to log inside the ZF2 application, you have two choices. First option is at bootstrap . It's
