Server tracing

The most useful way of tracing to my experience. First of all, I want to mention that this tracing module was introduced in Dynamics AX 4.0 and it heavily depends on Events Tracing for Windows subsystem (described in details in http://msdn.microsoft.com/en-us/libr...87(VS.85).aspx) So, if You have some problems with starting server trace, You should check that your AOS Server has appropriate Trace Provider installed. You can do it by running “logman query providers” command in AOS’ command prompt. Resulting output must have a line starting with “AOS Trace”. If your server does not have appropriate query provider, You can try to fix this by going into server’s BIN directory and running ‘mofcomp aos_trace.mof’ command. If your server has UAC turned on, this command must be run from command prompt with elevated privileges.

И еще цикл статей был.

У меня типичная ошибка была
1. Не выполнено "You can try to fix this by going into server’s BIN directory and running ‘mofcomp aos_trace.mof’ command"
2. Недостаточно места на диске (меньше 10 гигов свободного места)
3. Не в той конфигурации аоса прописаны настройки.

Попробуйте. Наверняка у вас примерно то же самое.
