EMC Centera Uptime Test

In most production environments, it is essential to monitor the uptime of critical systems in the infrastructure. By tracking the uptime of each of the systems, administrators can determine what percentage of time a system has been up. Comparing this value with service level targets, administrators can determine the most trouble-prone areas of the infrastructure. In some environments, administrators may schedule periodic reboots of their systems. By knowing that a specific system has been up for an unusually long time, an administrator may come to know that the scheduled reboot task is not working on a system.

This test included in the eG agent monitors the uptime of the target EMC Centera.

Target of the test : An EMC Centera storage system.

Agent deploying the test : A remote agent

Outputs of the test : One set of result for target storage system

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed.


The host for which the test is to be configured.


The port number at which the specified host listens. By default, this is NULL.

User and Password

In order to monitor an EMC Centera Storage, the eG agent has to be configured with the credentials of a read only user. Specify the login credentials of such a user in the User and Password text boxes.

Confirm Password

Confirm the password by retyping it here.

CerteraViewer JAR Path

Path of CenteraViewer on agent host. CenteraViewer is installed along with CenteraCLI. By default the installation path is C:\Program Files\EMC\Centera\2_4\SystemOperator\lib\CenteraViewer.jar

Timeout Seconds

Specify the time duration (in seconds) beyond which this test should time out in the TIMEOUT text box. The default is 120 seconds.

Measurements made by the test
Measurement Description Measurement Unit Interpretation


Indicates the time since last reboot.



Is rebooted

Indicates If the storage has been rebooted.


The Is Rebooted value of 0 indicates that a reboot is due, you may need to plan a reboot soon.

The values that this measure can report and their corresponding numeric values are tabulated below:

Measure Value Numeric Value
No 0
Yes 1


By default, this measure reports the above-mentioned Measure Values while indicating the status. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
