7.3 Logging the Trend of the Temperature inside the Chassis
7.3.1 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.
7.3.2 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 7-8 shows the name of each log file.
