These messages are called trace messages and are primarily used for debugging and to provide lower-level information then event messages, which system administrators primarily use. Dell EMC Networking OS retains executed trace messages for hardware and software and stores them in files (logs) on the internal flash.

• NV Trace Log — contains line card bootup trace messages that Dell EMC Networking OS never overwrites and is stored in internal flash under the directory NVTRACE_LOG_DIR.
• Trace Log — contains trace messages related to software and hardware events, state, and errors. Trace Logs are stored in internal flash under the directory TRACE_LOG_DIR.
• Crash Log — contains trace messages related to IPC and IRC timeouts and task crashes on line cards and is stored under the directory CRASH_LOG_DIR.
