Trace Logs
In addition to the syslog buffer, Dell EMC Networking OS buffers trace messages which are continuously written by various Dell
EMC Networking OS software tasks to report hardware and software events and status information.
Each trace message provides the date, time, and name of the Dell EMC Networking OS process. All messages are stored in a
ring buffer. You can save the messages to a file either manually or automatically after failover.
Auto Save on Crash or Rollover
Exception information for MASTER or standby units is stored in the flash:/TRACE_LOG_DIR directory. This directory contains
files that save trace information when there has been a task crash or timeout.
On a MASTER unit, you can reach the TRACE_LOG_DIR files by FTP or by using the show file command from the
flash://TRACE_LOG_DIR directory.
On a Standby unit, you can reach the TRACE_LOG_DIR files only by using the show file command from the flash://
TRACE_LOG_DIR directory.
NOTE: Non-management member units do not support this functionality.
Last Restart Reason
If the system restarts for some reason (automatically or manually), the show system command output includes the reason for
the restart.
The following table shows the reasons displayed in the output and their corresponding causes.
