Abstract: Techniques to provide unified logging services are described. An apparatus may comprise a memory to store a diagnostic manager component. A processor may be coupled to the memory, the processor operative to execute instructions for the diagnostic manager component. The diagnostic manager component may be operative to receive diagnostic messages for a diagnostic activity spanning multiple threads within a process, multiple processes or multiple devices, annotate the diagnostic messages with context information to form annotated diagnostic messages, and store the annotated diagnostic messages in a diagnostic log data file. Other embodiments are described and claimed.
