This test reports the current state of each aggregate in the NetApp Cluster.

The default parameters associated with this test are:

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

• Specify the host for which the test is to be configured in the HOST text box.

• The port number to which the selected server is listening has to be specified in the PORT textbox. 

• In the USER text box, specify the name of the user who possesses the readonly role. If such a user does not pre-exist, then, you can create a special user for this purpose using the steps detailed in the eG Measurements Manual.

• In the PASSWORD text box, specify the password that corresponds to the above-mentioned USER.

• Confirm the PASSWORD by retping it here in the CONFIRM PASSWORD text box.

• In order to collect metrics from the NetApp Cluster, the eG agent connects to the ONTAP management APIs over HTTP or HTTPS. By default, this connection is authenticated using the LOGIN_PASSWORD authentication mechanism. This is why, LOGIN_PASSWORD is displayed as the default AUTHENTICATION MECHANISM.

• Set the USE SSL flag to Yes, if SSL (Secured Socket Layer) is to be used to connect to the NetApp Unified Storage System, and No if it is not.

• By default, in most environments, NetApp Cluster listens on port 80 (if not SSL-enabled) or on port 443 (if SSL-enabled) only. This implies that while monitoring the NetApp Cluster, the eG agent, by default, connects to port 80 or 443, depending upon the SSL-enabled status of the NetApp Cluster - i.e., if the NetApp Cluster is not SSL-enabled (i.e., if the USE SSL flag above is set to No), then the eG agent connects to the NetApp Cluster using port 80 by default, and if the NetApp Cluster is SSL-enabled (i.e., if the USE SSL flag is set to Yes), then the agent-NetApp Cluster communication occurs via port 443 by default. Accordingly, the API PORT 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 API PORT parameter, you can specify the exact port at which the NetApp Cluster in your environment listens, so that the eG agent communicates with that port for collecting metrics from the NetApp Cluster.

• In the EXCLUDE AGGREGATES text box, if you wish to exclude certain aggregates from the scope of monitoring, specify a list of comma-separated aggregates in this text box. By default, none will be displayed here.

• In the TIMEOUT text box, specify the duration (in seconds) beyond which the test will timeout if no response is received from the device. The default is 120 seconds.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

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

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
