Onboard Failure Logging (OBFL)
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 data is displayed using the show logging onboard command. The message "No historical
data to display" is seen when historical data is not available.
Temperature
Temperatures surrounding hardware modules can exceed recommended safe operating ranges and cause
system problems such as packet drops. Higher than recommended operating temperatures can also
accelerate component degradation and affect device reliability. Monitoring temperatures is important for
maintaining environmental control and system reliability. Once a temperature sample is logged, the
sample becomes the base value for the next record. From that point on, temperatures are recorded either
when there are changes from the previous record or if the maximum storage time is exceeded.
Temperatures are measured and recorded in degrees Celsius.
