RE: Can we write the data to Multiple log

Why do you need to include anything in your UI? This is only my position on

Doesnt this reduce the value of your logging by quite some degree?

Hi,
From the UI how can I specify the details to which appender to use.
My requirement is like there will be two log:
- Complete Information, which contains data along with the stack trace
and many more parameters coming from the exception
- Simple information saying “There was a error with code and simple
details”
And in this case I need to log them in two different logs at a time.
Can you please send me the samples.
Thanks in advance.

RE: Can we write the data to Multiple log
OK are not suppose to use the DB.
Coming to logging. I need to use RollingFileAppenders for both of the
Logs.
When you say two logs, its one for the Application Developers who needs
to get complete information for them to track.
And the other log is for the Tivoli server which keeps tracking the
information of the logs.
And from UI I normally use only one statement saying
Private readonly log4net.ILog Log = log4net.logManager.GetLogger()
Log.Debug(GetformatedMessage(Application));
Log.Debug(GetformatedMessage(Tivoli));
I was asking you how can we write the information to the different logs.

RE: Can we write the data to Multiple log
I think the point I failed to make is this; in my opinion, handling the logging
from the UI is a bad thing, just configure your application to log as soon as
it is started.
Ron Grabowski sent a good example of how to do what you want to do, to which
you replied. Failing that, just include two rolling fille appeneders in your
config file set to look at different levels, i.e. everything for the developers
and then a different level for everyone else.
I think the biggest question here is what have you tried so far and what
problems did you encounter?

Re: Adding custom logging properties
Thanks Ron, that looks like it will allow me to populate the Properties
collection of the LoggingEvent instance.
Then, considering that the actual properties logged will differ per event I
guess I would combine this with my custom Layout class.
I think that gives me what I need.
Thanks again.

Subject: Re: Adding custom logging properties
Having a closer look at the documentation, the Properties property of the

ReadOnlyPropertiesDictionary which menas it can't be written to and hence
it's not suitable for my purposes.
Any ideas?

Ross,
I guess that's why I'm posting here, because I'm trying to devise a
pattern and some coding guidelines so that all our applications log
consistently. I considered wrapping log4net but all I've read advises
against that. So what I'm trying to achieve is an elegant solution that
makes the best use of the framework.
You're right, I wish to log a collection of Key-Value pairs associated
with a given loggin event. e.g.
statistics -
eventDataduration3ms/durationsize10kb/size/eventData
details -
eventDatacustomerID3/customerIDorderID10/orderID/eventData
The question I'm asking is how best to implement this with log4net?
Should I write a wrapper or a helper class that accepts the key-Value
pairs collection as a parameter and returns a formattred XML string that
then get's logged?
Maybe I should be creating a LoggingEvent in code manually, adding the
Key-Value pairs to the Properties collection and then using
ILog.Logger.Log to actually log the event rather than using Ilog.Info()
to
log. I could than write a custom layout class that serialises the
properties out as an XML string.
like I said, I'm not sure and am looking for some disrection.
Ideally I would have the following interface available to me:
ILog.Info(string message, Dictionary customProperties)
and then it would be the configuration that drives how the
customProperties are rendered by specifying the approporiate Layout
class.
That way I could format the customProperties to a file in one way and to
a
Db as XML etc... without embedding the formatting logic in my code.
Ross Hinkley wrote:
Adam,
How are these properties getting transformed from a logging call to XML?
Are you asking if there's a way to modify a custom format on the fly and
then turn the custom properties into XML? (I'm thinking of something
like
appending name-value pairs to the log format and having a custom
appender
do
the XML conversion for you. This doesn't seem terribly elegant.)
Maybe I'm over-trivializing, but it seems to me you should be able to
use
custom properties to take care of your current needs, converting your
properties to XML in code, then modifying the ADO appender configuration
to
handle that property appropriately when the logging database is
implemented.
I guess another question would be what sorts of things need to be
serialized? Are they going to be serialized from a class?

Experiencing locks while using AdoNetAppender
Hi, I am using the AdoNetAppender for logging messages from multiple application. All the applications log into one sqllite database.

Reducing the timeout may lead to events getting lost, but I prefer that to our application hanging for the full CommandTimeout waiting for the database to become unlocked. Is it possible to configure the timeout using configuration? or would it be better to choose for a solution like deriving from the AdoNetAppender and add the functionality?

RE: Does log4net support 64-bit Windows environments?
We are running on 64 bit windows here with no problems although our .NET applications are compiled 32-bit (not Any CPU) because they link to 32-bit native DLLs. Which logging appenders are you using? I'm not sure, but some of those might pInvoke out to native code. If the native code that gets invoked is 32-bit, then that will cause something like a BadImageFormatException. You get that exception in the DLL that is referencing the native code though, not the 32-bit native DLL, so it can be hard to track down. It could also be your code that is pInvoking out to 32-bit native DLLs, maybe through 3rd Party components. Personally, I haven't seen any 64-bit issues in .NET programs that weren't related to native interop. Can you describe the issues/exceptions you are seeing? It would be much easier to help you track down the problem.

Ron Grabowski sent a good example of how to do what you want to do, to which you replied. Failing that, just include two rolling fille appeneders in your config file set to look at different levels, i.e. everything for the developers and then a different level for everyone else. I think the biggest question here is what have you tried so far and what problems did you encounter?

Coming to logging. I need to use RollingFileAppenders for both of the Logs. When you say two logs, its one for the Application Developers who needs to get complete information for them to track. And the other log is for the Tivoli server which keeps tracking the information of the logs. And from UI I normally use only one statement saying Private readonly log4net.ILog Log = log4net.logManager.GetLogger() Log.Debug(GetformatedMessage(Application)); Log.Debug(GetformatedMessage(Tivoli)); I was asking you how can we write the information to the different logs.

The suggestions were to either configure two rolling file appenders or log to a DB. Why do you need to include anything in your UI? This is only my position on this, but - why do you want to specify which log you want to use in the UI? Doesnt this reduce the value of your logging by quite some degree?

My requirement is like there will be two log: - Complete Information, which contains data along with the stack trace and many more parameters coming from the exception - Simple information saying There was a error with code and simple details And in this case I need to log them in two different logs at a time. Can you please send me the samples. Thanks in advance.

Re: Experiencing locks while using AdoNetAppender
Not sure if this has changed, but I'm pretty sure there is a database lock on inserts/updates. So only one insert at a time. You might try the BufferedForwardingAppender. It might serialize the inserts for you. On Aug 18, 2009, at 8:36 PM, Ron Grabowski rongrabow...@yahoo.com wrote: I think that's how SQLite works.

asynchronous logging using log4net
Hello, Looking through the archives, I see attempts in the past to add asynchronous logging to log4net, but am not sure if the efforts have gone anywhere. I would appreciate some feedback on how to accomplish what is conceptually a pretty simple task. I would like to do the following: 1) have a logging thread solely responsible for the actual I/O component of logging (in this case, I'm only concerned with logging to console and/or to file). the logging thread would process logging events from some sort of queue 2) a way of having multiple producers append logging events to the logging queue from various producer threads One additional consideration: rendering - I want to be able to control when rendering occurs. Having rendering in the producer threads guarantees that the data rendered is what you actually want to log - assuming you're passing in mutable objects to the logging statements that might change between the time the logging call is made vs. when the logging message is actually rendered. Alternatively, if you are only passing in non-mutable objects or implicitly make the guarantee that nothing will change, rendering the logging message in the logging thread is more efficient. Based on what I want to do and from the googling I've done, I don't believe that writing a custom Appender will do this. Instead, it seems like the way to go is to implement a custom ILog object the proxies Debug / Log / Warn calls by adding the arguments to a queue. However, this is just a guess. Perhaps a better solution already exists. Any help / feedback here would be greatly appreciated. Thanks! Best, John P.S. I accidentally sent this message to the dev thread as well. So my apologies if you see this message there. I didn't mean to spam.
