Use this command to view OBFL data from the system hardware. The OBFL feature is enabled by
default and records operating temperatures, hardware uptime, interrupts, and other important events and
messages that can assist with diagnosing problems with hardware modules installed in a Cisco router or
switch. Data is logged to files that are stored in nonvolatile memory. When the onboard hardware is
started up, a first record is made for each area monitored and becomes a base value for subsequent
records.
The OBFL feature provides a circular updating scheme for collecting continuous records and archiving
older (historical) records, ensuring accurate data about the system. Data is recorded in one of two
formats: continuous information that displays a snapshot of measurements and samples in a continuous
file, and summary information that provides details about the data being collected. The message "No
historical data to display" is seen when historical data is not available.
This command does not require a license.
Examples This example shows how to display the OBFL boot and uptime information:
