Chassis Fans Test

A Cisco Blade Server Chassis contains the following components:

Cisco UCS Fabric Extenders—Up to two fabric extenders (FEX), each FEX provides four ports of 10-Gigabit Ethernet, Cisco Data Center Ethernet, and Fibre Channel over Ethernet (FCoE)
SFP+ transceiver choices that include copper and fiber optic
Power supply units—Up to four 2500 W hot-swappable power supply units
Fan modules—Eight hot-swappable fan modules
Cisco UCS Blade Servers —Up to eight half-wide blade servers or four full-width blade servers, each holding RAID capable hard drives

This test monitors the overall health of each fan present in each chassis managed by the Cisco UCS manager, and proactively alerts users to the following:

Fans that are in an abnormal operational state;
Fans that are in a critical performance/thermal/voltage state;
Fans in a degraded/errored power state;
Fans operating at abnormal speeds.

Target of the test : A Cisco UCS manager

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each fan in each chassis managed by the Cisco UCS manager being monitored.

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed.
Host	The IP address of the host for which the test is being configured.
Port	The variable name of the port at which the specified host listens.
UCS User and UCS Password	Provide the credentials of a user with at least read-only privileges to the target Cisco UCS manager.
Confirm Password	Confirm the password by retyping it here.
SSL	By default, the Cisco UCS manager is SSL-enabled. Accordingly, the SSL flag is set to Yes by default.
Web Port	By default, in most virtualized environments, Cisco UCS manager listens on port 80 (if not SSL-enabeld) or on port 443 (if SSL-enabled) only. This implies that while monitoring Cisco UCS manager, the eG agent, by default, connects to port 80 or 443, depending upon the SSL-enabled status of Cisco UCS manager - i.e., if Cisco UCS manager is not SSL-enabled (i.e., if the SSL flag above is set to No), then the eG agent connects to Cisco UCS manager using port 80 by default, and if Cisco UCS manager is SSL-enabled (i.e., if the SSL flag is set to Yes), then the agent-Cisco UCS manager communication occurs via port 443 by default. Accordingly, the WebPort parameter is set to default by default. In some environments however, the default ports 80 or 443 might not apply. In such a case, against the WebPort parameter, you can specify the exact port at which the Cisco UCS manager in your environment listens, so that the eG agent communicates with that port for collecting metrics from the Cisco UCS manager.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
