7.2 Logging the Trend of the Temperature inside the Chassis
7.2.1 Overview
This function periodically measures the temperature inside the chassis of this equipment and
records the data into a log file. You can adjust the logging interval for the temperature inside
the chassis by using the logging interval setup command. The default setting for the logging
interval is 60 minutes. You can select the setting from three options: 10, 30, and 60 minutes.
7.2.2 Log files
The temperature inside the chassis is recorded in a log file at the specified logging intervals.
When this equipment runs continuously for 8 hours or more, the highest and lowest
temperatures in 8 hours are also recorded every 8 hours. For either file, if the log gets full,
log entries are overwritten from the first entry.
Table 7-1 shows the name of each log file.
