Trace logs In addition to the syslog buffer, FTOS buffers trace messages which are continuously written by various FTOS software tasks to report hardware and software events and status information. Each trace message provides the date, time, and name of the FTOS process. All messages are stored in a ring buffer and can be saved to a file either manually or automatically upon failover. • There are two trace files for CP: software and command-history. • There is one trace file for LP: software. Automatic trace log updates The system automatically saves software trace files to the internal flash. The files are saved to the TRACE_LOG_DIR directory on the flash, and are named so that they can be viewed in a logical order. The first automatic trace file is labeled sw_trace_RPM0CP.0. Up to five trace logs are saved before the system begins overwriting them (sw_trace_RPM0CP.1, and so on until sw_trace_RPM0CP.4). Trace file sw_trace_RPM0CP.0 is not overwritten so that chassis bootup message are preserved. The trace file names are: • CP [SW trace] : • sw_trace_RPM[0|1]CP.0, sw_trace_RPM[0|1]CP.1, sw_trace_RPM[0|1]CP.2, sw_trace_RPM[0|1]CP.3 and sw_trace_RPM[0|1]CP.4 • LP [SW trace] : • sw_trace_LP[0-13].0, sw_trace_LP[0-13].1, sw_trace_LP[0-13].2, sw_trace_LP[0-13].3 and sw_trace_LP[0-13].4 Trace files are saved in the internal flash:/TRACE_LOG_DIR/TRACE_CURR_BOOT. Upon a system reload this directory is renamed flash:/TRACE_LOG_DIR/TRACE_LAST_BOOT, and a fresh empty flash:/TRACE_LOG_DIR/TRACE_CURR_BOOT directory is created. Save a trace log to a file on the flash The trace logs are saved automatically but you can save the contents of a buffer manually with the CLI. The files are named the same whether they are saved automatically or manually. To manually write the contents of a trace log on CP to a file on the flash: Task Write the buffered trace log to flash. Command Syntax upload trace-log cp [cmd-history | sw-trace] Command Mode EXEC Privilege E-Series ExaScale Debugging and Diagnostics | 1125
