Volume State Test

This test auto-discovers the volumes on the NetApp Cluster and monitors the current state of each volume. In addition, this test reports if the current state of the volume is Inconsistent/Unrevoverable/Invalid along with throwing insights on whether the NVFAIL flag is enabled on the volume.

Target of the test : A NetApp Cluster

Agent deploying the test : An external/remote agent

Outputs of the test : One set of results for each aggregate on the NetApp Cluster being monitored.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.

Host

The IP address of the storage controller cluster.

Port

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

User

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.

Password

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

Confirm Password

Confirm the Password by retyping it here.

Authentication Mechanism

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.

Use SSL

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.

API Report

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.

Exclude Aggregates

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.

Timeout

Specify the duration (in seconds) beyond which the test will timeout if no response is received from the device. The default is 120 seconds.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

State

Indicates the current state of this volume.

 

The values that this measure can report and their corresponding numeric values have been listed in the table below.

Measure Value Numeric Value
Online 0
Mixed 1
Restricted 2
Offline 3

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the current state of this volume. However, in the graph of this measure, Measure Values will be represented using the corresponding numeric equivalents i.e., 0 to 3.

Is inconsistent?

Indicates whether/not the state of this volume is Inconsistent.

 

This measure reports a value Yes if this volume is inconsistent and No if otherwise.

The values that this measure can report and their corresponding numeric values have been listed in the table below.

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether the volume is inconsistent or not. However, in the graph of this measure, Measure Values will be represented using the corresponding numeric equivalents i.e., 0 or 1.

 

Is invalid?

Indicates whether/not the state of this volume is Invalid.

 

This measure reports a value Yes if the state of this volume is invalid and No if otherwise.
