问题 I have a little issue with fluend log parser. I have varnish server on which I have set up the X-Forwarded-For parameter to content the list of ip all the host stack a http request goes through. I use this to get information in varnishncsa logs. This is and example of log : "192.168.79.16, 192.22.10.22, 10.2.2.22 - - [13/Aug/2015:09:50:45 +0000] \"GET http://poc.mydomain.com/panier/payment/payline?notificationType=WEBTRS&token=1KB01BwKWdUhVj1222301439454223514 HTTP/1.1\" 401 0 \"-\" \"Java/1

问题 I have scheduled two powershell scripts as tasks to run at 00:00. This morning I checked the event log and found that one of the scripts failed with the following exception: Failure. The error was: 'Failed to create log entry in: ‘C:\Users\SPSETU~1\AppData\Local\Temp\PowerShellLog.txt’. The error was: ‘The process cannot access the file 'C:\Users\SPsetupAdmin\AppData\Local\Temp\PowerShellLog.txt' because it is being used by another process.’.'. Can be the problem related to logs? Both the

问题 I have built a custom job log framework which logs all of the tasks which are execute in an SSIS package along with any error that surface. Once complete, an enhancement was requested to also store any SQL queries that the SSIS package executes on the SQL Server. This is not limited to only Execute SQL tasks, they are looking for ANY SQL queries that the pack runs. I am aware of the OnInformation logging that is part of the SSIS logging framework, but this only shows some of the query. Thanks

问题 When writing a custom TraceListener how can I force the writeheader, the data/messsage, and the writefooter to be one discreet record? Specifically the custom tracelisteners in question write to a non file based source, such as database or event stream. I need to either have the writeHeader, writefooter base methods in TraceListener be ignored or somehow packaged into a single write event. 回答1: Here is a good article on how custom TraceListener s work, which also explains when and wh

问题 I've seen questions about how to not log 404 errors to the error log, this is the opposite. For some reason my apache installation does not log 404 errors to my error log (or to my access log for that matter). I have set the error log properly and see errors going to it, but when I access non-existent pages I simply get my 404 error - the access (but not the 404 error) shows up in the access.log, but I don't see anything in the error log (which makes it hard, for example, to debug why some

问题 I'm using MSTest and I want to write log entry before test executes and after it finishes. Obviously I don't want to add custom logging code at the beginning and end of each test - it would only make the test unreadable and seemed like a lot of effort (I have > 500 tests) Using TestInitialize and TestCleanup seemed like the way to go but I can't get the test name. Does anyone knows how to do this? 回答1: In MSTest, the name of the test case is available in the test context property. So to

问题 What is the best option for writing (appending) records to file in highly parallel web environment in .net4 IIS7? I use ashx http handler to receive small portions of data that should be written to file quickly. First I used: using (var stream = new FileStream(fileName, FileMode.Append, FileAccess.Write, FileShare.ReadWrite, 8192)) { stream.Write(buffer, 0, buffer.Length); } But I noticed that some records were broken or incomplete, probably because of FileShare.ReadWrite. Next I tried to

问题 My app creates a log for the application itself, so record when it was activated, and what happened at an application level. The application is centered around 'profiles' - the user loads a profile which tells the application where/when/what/how. So I also want to create a log for each profile, to record the progress each time the profile is run. No problems so far... except that I want the profile log to be stored alongside the profile itself, so this means I need to configure NLog

问题 I am using TimedRotatingFileHandler to create my logs. I want my log files to be created every minute, keep at most 2 log files and delete older ones. Here is the sample code: import logging import logging.handlers import datetime logger = logging.getLogger('MyLogger') logger.setLevel(logging.DEBUG) handler = logging.handlers.TimedRotatingFileHandler( "logs/{:%H-%M}.log".format(datetime.datetime.now()), when="M", backupCount=2) logger.addHandler(handler) logger.debug("PLEASE DELETE PREVIOUS
