About OBFL

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
• CPU hog information
• Memory leak information
• Software error messages
• Hardware exception logs
• Environmental history
• OBFL-specific history information
• ASIC interrupt and error statistics history
• ASIC register dumps

Virtualization Support

You must be in the default virtual device context (VDC) to configure and display OBFL information. See the
Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide for more information on VDCs.
