About OBFL

Cisco NX-OS provides the ability to log failure data to persistent storage, which you can retrieve and display
for analysis at a later time. This onboard failure logging (OBFL) feature stores failure and environmental
information in nonvolatile memory on the module. The information will help analyze failed modules.
OBFL stores the following types of data:
• Time of initial power-on
• Slot number of the module in the chassis
• Initial temperature of the module
• Firmware, BIOS, FPGA, and ASIC versions
• Serial number of the module
• Stack trace for crashes
