Blade Logical Disks Test

This test auto-discovers the logical disks of the target Cisco UCS Manager and helps you in continuously monitoring the overall health, operability, and availability of each logical server managed by the Cisco UCS Manager, and be alerted to anomalies as soon as they occur. This way, you can initiate required corrective actions before your mission-critical services begin to suffer. In addition, the test also captures critical power and thermal failures experienced by the logical disks. Besides, this test also helps administrators figure out the size of each logical disk and the number of blocks available on each disk. Using this test, administrators can figure out the disks that are frequently encountering failures.

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 logical disk 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.
