Aggregate Space Test

How often should the test be executed.

The IP address of the storage controller cluster.

Specify the port at which the specified host listens in the Port text box. By default, this is NULL.

Here, 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 Creating a New User with the Role Required for Monitoring the NetApp Cluster.

Specify the password that corresponds to the above-mentioned User.

Confirm the Password by retyping it here.

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.

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.

The eG agent by default, executes the API commands in order to query the aggregates in the target environment. In critical infrastructures spanning large number of aggregates, a single execution by the eG agent may query(or download) a sizeable amount of monitoring data, thereby adding to the cluster load. To avoid this, you can tweak the Records Per Call parameter to enable the eG agent to obtain monitoring data iteratively in chunks instead of retrieving the entire amount of monitoring data in a single go. Say for example, the eG agent is required to query 1000 aggregates, then specifying the value 100 in this text box will enable the eG agent to query 100 aggregates at a time for 10 times to obtain monitoring data from all the aggregates. By default, the value of this parameter is 10.
