# log4net.Azure
An appender that plugs into the Trace-pipeline w/ the logging that Windows Azure uses.
## Requirements:
* .Net 4.0
* libs from above
## Using it:
First, install it; `install-package log4net.Azure`
Secondly, use it;
```
public class Log4NetSampleWorker : RoleEntryPoint
{
private static readonly ILog _logger = LogManager.GetLogger(typeof (Log4NetSampleWorker));
public override void Run()
{
_logger.InfoFormat("{0}'s entry point called", typeof(Log4NetSampleWorker).Name);
while (true)
{
Thread.Sleep(10000);
_logger.Debug("Working...");
}
}
public override bool OnStart()
{
BasicConfigurator.Configure(AzureAppender.New(conf =>
{
conf.Level = "Debug";
conf.ConfigureRepository((repo, mapper) =>
{
repo.Threshold = mapper("Debug"); // root (defaults to 'All')
});
}));
return base.OnStart();
}
}
```
The configurator gives you access to doing things like this as well;
```
BasicConfigurator.Configure(AzureAppender.New(conf =>
{
/* in this case we say that appender should be in debug mode
* but that we should only transfer logs to storage that is information-level
* or above.
*
* That doesn't make sense unless you're also doing debugging and want the debug
* output in the trace viewer or you have another trace message sink.
*
* Please note the wonderful *three* types of logging levels here! Nice. Not to
* mention that you can do the equivalent of conf.Level = "Debug" in the cscfg file.
*/
conf.Level = "Debug";
conf.ConfigureRepository((repo, mapper) =>
{
repo.Threshold = mapper("Debug"); // root
});
conf.ConfigureAzureDiagnostics(dmc =>
{
dmc.Logs.ScheduledTransferLogLevelFilter = LogLevel.Information;
});
}));
```
## Building:
1. Install libs: http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=28045
2. Run `gem install bundler` (if not already installed)
3. Run `gem install semver2` (if not already installed)
4. Run `rake`.
Assumes your diagnostics connection string is named: `Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString`. It turns out one can't change this in the cscfg files in VS.
Optional Settings (that can also be set through the `ConfigureAzureDiagnostics` method call):
* `Diagnostics.Level` - [level of logging](http://logging.apache.org/log4net/release/manual/introduction.html), unless configured in code. Accepts { 'Debug', 'Info', 'Warn', 'Error', 'Fatal', 'Off', 'All' }. Defaults to 'Info'.
* `Diagnostics.Layout` - [pattern layout](http://logging.apache.org/log4net/release/sdk/log4net.Layout.PatternLayout.html), unless configured in code. Defaults to `"%timestamp [%thread] %level %logger - %message%newline"`
* `Diagnostics.ScheduledTransferPeriod` - transfer period, unless configured in code. [ms] Defaults to 60000 ms.
* `Diagnostics.EventLogs` - event-logs key. Defaults to `Application!*;System!*`
