This test is used to know the VirtualCenter Management server configuration for Mail Sender settings.

This page depicts the default parameters that need to be configured for the VCMailSettings_cf .

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed. 

• To connect to vCenter and extract metrics from it, this test should be configured with the name and password of a user with Administrator or Virtual Machine Administrator privileges to vCenter. However, if, owing to security constraints, you are not able to use the credentials of such users for test configuration, then you can configure this test with the credentials of a user with Read-only rights to vCenter. For this purpose, you can assign the 'Read-only' role to a local/domain user to vCenter, and then specify name and password of this user against the VC USER and VC PASSWORD text boxes.

  vCenter servers terminate user sessions based on timeout periods. The default timeout period is 30 mins. When you stop an agent, sessions currently in use by the agent will remain open for this timeout period until vCenter times out the session. If the agent is restarted within the timeout period, it will open a new set of sessions. If you want the eG agent to close already existing sessions on vCenter before it opens new sessions, then, instead of the 'Read-only' user, you can optionally configure the VC USER and VC PASSWORD parameters with the credentials of a user with permissions to View and Terminate Sessions on vCenter. For this purpose, you can create a special role on vCenter, grant the View and Terminate Sessions privilege to this role, and then assign the new role to a local/domain user to vCenter.

• Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• By default, the vCenter server is SSL-enabled. Accordingly, the SSL flag is set to Yes by default. This indicates that the eG agent will communicate with the vCenter server via HTTPS by default.

• By default, in most virtualized environments, vCenter listens on port 80 (if not SSL-enabeld) or on port 443 (if SSL-enabled) only. This implies that while monitoring vCenter, the eG agent, by default, connects to port 80 or 443, depending upon the SSL-enabled status of vCenter - i.e., if vCenter is not SSL-enabled (i.e., if the SSL flag above is set to No), then the eG agent connects to vCenter using port 80 by default, and if vCenter is SSL-enabled ((i.e., if the SSL flag is set to Yes), then the agent-vCenter 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 vCenter in your environment listens, so that the eG agent communicates with that port for collecting metrics from vCenter.

• Once the necessary values have been provided, clicking on the Update button will register the changes made.

When changing default configurations of tests, the values with "$" indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to "xyz" and $port will be changed to "80" when configuring a test.
