Temperature Log Reduction
Depending on settings and temperature readings, the fan speeds are changed dynamically within the following
ranges: low, med, med-hi, and high. Fan speed changes are determined by temperature thresholds set for
sensors on the management modules, interface modules and switch fabric modules. When a temperature
threshold is crossed upward on any module, the fan speed changes to the assigned fan speed. This occurs even if
the temperature is within the threshold for the slower fan speed on other modules. With previous versions of the
Multi-Service IronWare software, a log message is sent whenever a temperature threshold is crossed on any
module whether the fan speed is actually increased or not. This can result in excessive log messages being sent.
With version 03.2.01 of the Multi-Service IronWare software the default behavior is for a log message to be sent
only when the fan speed is actually changed. This reduces the number of messages sent. In addition, a new CLI
option is available that allows you to log all messages (backward compatibility mode) or have a single log message
sent when any of the temperature thresholds are crossed. The log message has also been improved with this
release to include the speed that the fan has been changed to.
Details about how to set temperature thresholds and default threshold values are described in the “Configuring the
Cooling System” on page 5-6
Configuring Temperature Logging
The following command sets the temperature logging threshold to
which will send a single message whenever any of the thresholds are crossed.
NetIron(config) temp-log-threshold low
Syntax:
temp-log-threshold [verbose | high | low | med | med-hi]
The
verbose
option sets temperature logging to generate logs whenever temperature threshold is crossed. This is
the operational mode of previous versions of Multi-Service IronWare software and provides backward
compatibility.
The
high
option sets temperature logging to generate logs only when the high threshold is crossed.
The
low
option sets temperature logging to generate logs whenever any threshold (low, medium, medium-high or
high) is crossed.
The
med
option sets temperature logging to generate logs only when the medium, medium-high, and high
thresholds are crossed.
The
med-high
option sets temperature logging to generate logs only when the medium-high and high thresholds
are crossed. This is the default setting.
