Maybe check the Umbraco source to see how the LogHelper is used there?

Umbraco logging uses log4net, the TYPE should be the type of the object / class you are loggin, usually is used in this way:

//You can specificy the class your are logging
LogHelper.Error(typeof(MyClass), "msg", e);
//Otherwise, you can use this code, that gets type automatically
LogHelper.Error(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType, "msg", e);

Hi Joao,

Thanks for your help. I'm doing my logging within a Razor script so I was unsure what class was being logged. The full script I am testing is:

try
    {
        client.EnableSsl = true;
        client.Send(mail);
        <p><strong>Your contact request has been sent. Someone will be in contact shortly</strong></p>
    }
    catch (Exception ex)
    {
        //LogHelper.Error(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType, "Error creating or sending contact mail", ex.InnerException);
        umbraco.BusinessLogic.Log.Add(umbraco.BusinessLogic.LogTypes.Error, -1, string.Format("Error creating or sending contact mail: {0}", ex.InnerException));
        <p>Error: An error has occured sending your contact details. Please contact us directly using the phone or email listed above.</p>
    }

Even the old way of doing things is not recording an entry in the umbracoLog table so I'm wondering if there is an issue with v6.

Cheers

Hi Paul,

currently I haven't tried the old api for logging on Umbraco V6, but I've used the new one and it works properly.

So I suggest you to just change your code to use the new API, this simple code will work:

LogHelper.Error(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType, "msg", ex);

@Joao, v6 now logs using log4net so take a look in /App_data/logs/ for your log entries and not the DB table. Hope that helps.

Really useful post thanks! I would add that to use the v6 log4net LogHelper you need to reference Umbraco.Core.Logging

e.g in a Razor script:

@using Umbraco.Core.Logging;
@{
LogHelper.Info(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType, "Message"); 
} 

Darren Ferguson has a great blog post on custom logging here.

Maybe not exactly what you need but certainly useful nonetheless.

OK, answering myself, addding

using Umbraco.Core.Logging;

then you can call:

LogHelper.Info(this.GetType(),string.Format("blblb"));
