XIO SC Nodes Test
This test monitors each storage controller of the target EMC XtremIO storage array and reports the overall health of the storage controller along with its contained components. This test also reports the current temperature of the front panel of each storage controller, the journaling state and the connection state between the XMS and each storage controller. Using this test, administrators can figure out the storage controllers that were disconnected from the XMS and the reason behind why the storage controller stopped working.
Target of the test : An EMC XtremIO Storage array
Agent deploying the test : A remote agent
Outputs of the test : One set of results for each Storage Controller node on the target EMC XtremIO being monitored
| Parameter | Description |
|---|---|
|
Test Period |
How often should the test be executed. |
|
Host |
The IP address of the storage device for which this test is to be configured. |
|
Port |
The port number at which the storage array listens. The default is NULL. |
|
XtremIO User and XtremIO Password |
Provide the credentials of a user who has read only privileges to access the XtremIO storage array in the XtremIO User and XtremIO Password text boxes. |
|
Confirm Password |
Confirm the password by retyping it here. |
|
SSL |
The eG agent collects performance metrics by invoking Restful APIs on the target Storage array. Typically, the Restful APIs can be invoked through the HTTP or the HTTPS mode. By default, the eG agent invokes the Restful APIs using the HTTPS mode. This is why, the SSL flag is set to Yes by default. If the target storage array is not SSL-enabled, then the Restful APIs can be accessed through the HTTP mode only. In this case, set the SSL flag to No. |
|
XMS IP |
This parameter is applicable only for EMC XtremIO 4.x. By default, None will be chosen from this list. If the target EMC XtremIO storage array is within a XMS Management Server that is auto-discovered, then the IP or host name of that XMS Management Server will be displayed in this list. Select that particular XMS IP to configure this test. If you wish to monitor an EMC XtremIO Storage Array that is either not an integral part of the auto-discovered XMS Management Server or a brand new EMC XtremIO Storage Array, choose the Other option. This will enable you to add a new XMS Managament Server. To know how to add a new XMS Management Server, refer to Adding a new XMS. |
|
DD Frequency |
Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 2:1. This indicates that, by default, detailed measures will be generated every second time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency. |
|
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:
