Configuration of NAUSDNFSIOStatsTest

This test auto-discovers the versions of NFS used on the storage system, and reports the following for each NFS version:

  • The status of the NFS server;
  • Whether all NFS messages have been drained from the NFS queue and the server has been disabled;
  • The rate of read-write requests processed by the NFS server and latencies in I/O processing (if any)

Note:

Before attempting to configure this test, ensure that the NetApp Managability SDK (NMSDK) is available on the eG remote agent host. Click here to know more about how to configure the eG agent to use the NMSDK.

The default parameters associated with this test are as follows:

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

  • In the HOST text box, specify the IP address of the storage device for which this test is to be configured.

  • Specify the port at which the specified HOST listens in the PORT text box. By default, this is set to NULL.

  • Specify the name of the user who possess the required privileges to monitor the storage device in the USER text box. If such a user does not pre-exist, then, you can create a special user for this purpose.

  • Specify the password that corresponds to the above-mentioned USER in the PASSWORD text box.

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

  • In order to collect metrics from the NetApp Unified Storage system, 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 Unified Storage system listens on port 80 (if not SSL-enabled) or on port 443 (if SSL-enabled) only. This implies that while monitoring the NetApp Unified Storage system, the eG agent, by default, connects to port 80 or 443, depending upon the SSL-enabled status of the NetApp Unified Storage system - i.e., if the NetApp Unified Storage system is not SSL-enabled (i.e., if the USE SSL flag above is set to No), then the eG agent connects to the NetApp Unified Storage system using port 80 by default, and if the NetApp Unified Storage system is SSL-enabled (i.e., if the USE SSL flag is set to Yes), then the agent-NetApp Unified Storage system 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 Unified Storage system in your environment listens, so that the eG agent communicates with that port for collecting metrics from the NetApp Unified Storage system.

  • A vFiler is a virtual storage system you create using MultiStore, which enables you to partition the storage and network resources of a single storage system so that it appears as multiple storage systems on the network. If the NetApp Unified Storage system is partitioned to accommodate a set of vfilers, specify the name of the vfiler that you wish to monitor in the VFILERNAME text box. In some environments, the NetApp Unified Storage system may not be partitioned at all. In such a case, the NetApp Unified Storage system is monitored as a single vFiler and hence the default value of none is displayed in this text box.

  • Specify the duration (in seconds) beyond which the test will timeout if no response is received from the NetApp Unified Storage system. By default, the timeout period 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.
