I am currently looking into papertrail and find it very interesting. However my web application will be deployed to web servers that I don't control. The problem is that I use this solution to send logs to papertrail: http://help.papertrailapp.com/kb/configuration/nlog-net-logging
And the way I see it I can't send logs on a website with medium trust level: http://technet.microsoft.com/en-us/library/cc754779.aspx
Is this right? Do you have any experience with using papertrail on medium trust sites?
Yes you are right:
Medium (web_mediumtrust.config) - Specifies a medium level of code access security, which means that, in addition to High Trust Level restrictions, the ASP.NET application cannot do any of the following things by default:
Access files outside the application directory.
Access the registry.
**Make network or Web service calls.**
As far as I can see is the papertrail logger using the network to do the logging to an external site/service.
