Are 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 write an application that retrieves entries in the MMC event logs (application, system and security events) and would like to do so in ASP if possible. This is an internal application. Someone told me to use PowerShell.
Is it possible to do this in ASP (and use PowerShell) or do I need to use some other tools? I would like to retrieve events into a DataGrid etc.
1.what is the difference between design patterns vs architectural patterns ?
2. In which situations They are preffered?

View 4 RepliesI am trying to set up my web site on a stand alone server using Windows Server 2003 with IIS 6 which will access SQL server database (2008) on windows 2008 R2 server (also not in the domain) I am using form authentication and I have configured a custom identity account in IIS6. The local account is on both servers with same password and I have registered the account using aspnet_regiis.exe -ga The application pool in my iis6 has the custom local account set as the identity and my web.config file has the appropriate tags in the system.web element <identity impersonate="true" />
The problem is the local account does not seem to get passed to the sql server. Right now my iis settings are anonymous access (using the local acct vs isr) and no authentication specified under that - I did try Integrated and basic but it prompts for the username and password which I do not want. One article I read stated this: windows authentication does not support delegation (passing credentials from one server to another) and is limited to the one hop rule, only a primary token can be passed to a second server. windows
authentication on iis (all versions) gives the thread a secondary(impersonation) token which can not be used to access any network resouce
now our company creates a new application under ASP.NET + SQL Server cluster platform.
So I know the best and most efficient principles and ways to scale the load, but I wanna know the MS background of horizontal scaling.
The question is pretty simple - are there any built-in abilities in ASP.Net to access the least loaded SQL server from SQL Server cluster?

View 1 Replieswe 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've set up the health monitoring system to output to the event log. Everything is working fine, though I'm wondering if there is a way to:
A) Define the event source as my application name (it currently appears as ASP.NET 2.0.50727.0)
B) Adjust the level of severity. Currently, all events are recorded as a "Warning", and it would be nice to tag some as "Error".
I need to implement a wizardy, dynamic UI that uses complex validation of the style:
If A = 1, show controls B, C, D. B is required, C is not, and D is not required must be less than 30 if it is populated.
If A = 2, show controls B, D, E. B is not required, D is required but has no limits, and E is not required.
If B is not null, show controls B, D, E. B is not required, D is required but has no limits, and E is not required.
Historically, I have made my presentation layer as "dumb" as possible in that it is only responsible for capturing user input and binding it to the appropriate domain model. The domain model, in turn, contains the logic needed to validate it's state and that of any child objects, and then communicates any invalid state to the presentation layer via notifications. As such, this requirement for a highly "intelligent" UI represents a departure for me.
I think I have no choice but to construct 2 very similar class hierarchies:
one that will capture presentation business rules (i.e. what fields are visible) and control what renders in the View
one that will capture domain business rules (when field A = X, then field B should be not null and in the range of n to m) to disallow objects with an invalid state from being persisted
Sill I have far more questions than answers on my strategy moving forward. Is there a set of design patterns I can draw on to build such a dynamic UI? I do have the option of using ASP.NET MVC or WebForms, so whichever approach will produce cleaner, testable code is preferred.
