View 2 RepliesI'm debugging some unexpected behavior and while tracing in to the .NET framework I see a bunch of stuff like this:
if (Logging.On) {
Logging.PrintInfo(Logging.Web, this, SR.GetString(SR.net_log_n_certs_after_filtering, filteredCerts.Count));
...
}
But (as expected by default) the execution steps right over these. Is there some way to turn on the logging? Or is that just something that the framework developers can do while making special builds of the framework?
We have an ASP.NET MVC site that uses Entity Framework abstractions with Repository and UnitOfWork patterns. What I'm wondering is how others have implemented navigation of complex object graphs with these patterns. Let me give an example from one of our controllers:
[code]....
It's a registration process and pretty much everything hangs off the POCO class Person. In this case we're caching the person through the registration process. I've now started implementing the latter part of the registration process which requires access to data deeper in the object graph. Specifically DPA data which hangs off Legal inside Country.
The code above is just mapping out the model information into a simpler format for the ViewModel. My question is do you consider this fairly deep navigation of the graph good practice or would you abstract out the retrieval of the objects further down the graph into repositories?
Does anyone have a working pattern for converting a GET-POST-GET pattern to asny?
I'm encountering the following issues:
1. You cannot mix Sync and Async action methods SubmitForm(), SubmitFormAsync(bool? confirm), SubmitFormCompleted() ... (because the resolver gets all confused ... it doesn't use the HTTP verb to decide who to target. BTW: I think that's poor design, or a bug)
2. Renaming the get method name to something else eg: SubmitFormConfirmation(), SubmitFormAsync(bool? confirm), SubmitFormCompleted() would be very awkward if it works ... because you have to doctor the <form markup to specify an action name.
3. You cannot give them all async names SubmitFormAsync(), SubmitFormAsync(bool? confirm), submitFormCompleted(), because the call just keeps malfunctioning. It sometime even behaves as if you are requesting a delete of something.
Can someone give an insight from an actually working sample.
I'm using MS Enterprise Logging Application Block in an ASP.NET website.
For production launch, I will set up a log listener in one of these locations:
Sql Server database
Windows event log
Text files
Which has the least impact on performance?
NB - I can't switch to Log4Net or ELMAH at this point, so don't suggest that in your response.
Now that the next version of ASP.NET MVC is being prototyped and previewed (ASP.NET MVC 3 Preview 1 came out a couple of weeks ago), I wonder if we should call the attention of the Core Dev team (S Hanselman, Phil Haack and all) to this "feature."there a easy/non tacky way of associating subdomains → areas?Something like:

I spent a day trying to make Ent Lib Logging work and log anything into database or event log. I have a web application and console application with the same Ent Lib config but only the console application is capable to log into the Event Log. I tried everything with permissions but I don't know what exactly I am doing — which services should have what. It does not work!
I read articles like this[URL] and I want to try to give the ASPNET account those permissions. I am using Windows 7 and I cannot find ASPNET user account. So where is it?
This is the config file which is automatically generated from Ent Lib utility and it works only on App.config, not on web.config:

I think my subject line explains my problem in a nutshell.. I have a login page, I login like I should and everything works.I logout and when I type/paste the address to the page, in the address field, I still reach it just like if I was still logged in..The page I type in the address field is in a subfolder, only suppose to be able to be reached by logged in users and in this folder,ith it's own web.config-file:
<?xml version="1.0"?>

we are currently implementing logging functionality with Log4net into our ASP.NET web-services. Therefore we have installed Log4net into the GAC (global assembly cache) on every machine. On our Windows 2003 servers this works just fine.Funny thing is, when developing on our local clients, logging with Log4net doesn't work unless we copy the log4net.dll into the Bin folder of the ASP.NET website even though it is already installed in the GAC. This behaviour is for my colleague's machine and me and we just can't find the reason why. The application is identically like on the server and we installed Log4net the same way into the GAC but it behaves differently.We've tested it with the VS2008 integrated web-server as well as with IIS (WinXP).

How do I need to log this error to my database table? what do I need to write in my Class? to store the values in the table
We have an application that logs using log4net. But we would like to delete the logfiles every 4 weeks (automatically). Is there an option in log4net to do this or do we need to have a work arround?

I currently write all log4net events to a database, and it seems to work just fine. To capture the logged in user account I use this piece of code:
HttpContext context = HttpContext.Current;
if (context != null && context.User != null && context.User.Identity.IsAuthenticated)
{
MDC.Set("user", HttpContext.Current.User.Identity.Name);
}
The code seems ok, except for events that have no user context associated with them (ie. a user on our public web page). In that case the log4net capture seems to sometime write the last logged in user account (bad) and sometime write a null (good). Anyone got this feature to work reliably in all cases? I believe I saw a note that MDC is no longer a recommended feature to use, but I wasn't able to find any alternatives that are recommended.
Note: I find it odd that MDC is set with an account name, but never cleared if no user is active. That could be part of the problem. However, I didn't find any MDC code extracts that also clear the username.
I'm using log4net to log my web app's progress, using Log4PostSharp to AOP-injectify all methods. This has the desired effect of logging (almost) everything and is fine.I now have a requirement to log JUST Page_Load methods to a file / console. I can obviously hamstring the log4postsharp class to do that, but then I'd be losing all the other logging.I've been looking at filters in log4net, starting with the StringMatch filter, but that only looks at the message being logged, and I'm after the method name. This put me onto the PropertyFilter, but still with no joy. My log4net.config snippet is thus:

How to log MethodName when wrapping Log4net?
I have tons of requests in log4net that show up manually as ": activity". The requests are all manually built and somewhat clumsy. Is there any way for Log4Net to pick up the source function and record that automatically?
I am currently following instructions in a book to develop an application. It asks me to download StructureMap and then move the StructureMap.Dll file and the Log4Net.dll into the bin files. The problem is there doesnt seem to be a Log4Net.dll file in the StructureMap files, the only other dll apart from the StructureMap.dll is the Rhino.Mock.dll.
View 2 RepliesI just came across the two sections in log4net configiurations:
<logger name="File">
<level value="All" />
</logger>
<root>
<level value="INFO" />
</root>
May I know what is the differnce of specifying levels at logger and root tags ?
I'm trying to get log4net working in a 'classic' webforms app, using a log4net XML configuration file that I know is correct, as it is a copy of a file I use successfully with a number of other applications. I have the config.log4net file in the main site folder (C:inetpubwwwroot), and I configure log4net in Global.asax.cs as follows:
protected void Application_Start(Object sender, EventArgs e)
{
var log = LogManager.GetLogger("SomeWebsite");
XmlConfigurator.Configure(new FileInfo("config.log4net"));
// bind log to the DI container
...
}
Whenever I then use the log instance (even within Application_Start) nothing happens, not even an error. I know that if config.log4net is misconfigured, log4net will silently fail, but I am sure that this isn't the problem. I have a feeling it has to do with FileInfo's base path being wrong.
i want to print only web service start in log file instead of this message in log4net
FATAL - System.Object Web service start
I want log4net to write to my ADO log immediately but it doesn't seem to do it until the application exists, how can I remedy this?
View 1 Replieswe have bridged our log4net with Jira using SMTP.
Now we are worried that since the site is public what could happen to the Jira server if we get alot of issues in the production environment.
We have already filtered on Critical and Fatal, but we want to see either some acumulator service on log4net or a plain filter which identifies repeating issues and prevents them from being sent via Email. Preferably without having to change the error reporting code, so a config solution would be best.
Is is possible to configure FileAppender in log4net to add new entries at the beginning of log file? Currently it is adding entries at the end and reading newest entries requires scrolling whole log down. It would be more comfortable to read from the beginning.
View 2 RepliesAre there any patterns or practices for monitoring log4net exception logs across a cluster of web servers. I have considered several options including the following:
A central database
A log file retrieval system
A service based loggin architecture
I need to log entries into a log file.This should be done in the data access layer.At present,I am using the standard IO for making the log entries.But I need to use the log4net provider instead of standard IO for the log provider.I have added the log4net as a reference to my project.
