NetApp Clone Operations Test

The cloning feature is based on WAFL block sharing and provides fast and almost 100% space efficient file and sub-file cloning, which can also be applied for LUN and sub-LUN cloning.

This test reports the number of clone operations that are currently running and the number of clone operations that have failed in the NetApp Unified Storage system.

Target of the test : A NetApp Unified Storage

Agent deploying the test : An external/remote agent

Outputs of the test : One set of results for the NetApp storage system being monitored.

Configurable parameters for the test
Parameters	Description
Test Period	How often should the test be executed.
Host	The host for which the test is to be configured.
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 following privileges: login-http-admin,api-aggr-check-spare-low,api-aggr-list-info,api-aggr-mediascrub-list-info,api-aggr-scrub-list-info,api-cifs-status,api-clone-list-status,api-disk-list-info,api-fcp-adapter-list-info,api-fcp-adapter-stats-list-info,api-fcp-service-status,api-file-get-file-info,api-file-read-file,api-iscsi-connection-list-info,api-iscsi-initiator-list-info,api-iscsi-service-status,api-iscsi-session-list-info,api-iscsi-stats-list-info,api-lun-config-check-alua-conflicts-info,api-lun-config-check-cfmode-info,api-lun-config-check-info,api-lun-config-check-single-image-info,api-lun-list-info,api-nfs-status,api-perf-object-get-instances-iter,api-perf-object-instance-list-info,api-quota-report-iter,api-snapshot-list-info,api-vfiler-list-info,api-volume-list-info-iter*. 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 Privileges Required for Monitoring the NetApp Unified Storage.
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 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.
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 Port	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.
vFilerName	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.
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.
DD Frequency	Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Running operations	Indicates the number of clone operations that are currently running in this storage system.	Number	The detailed diagnosis of this measure lists the Operation ID, UUID of the cloned volume, type of the cloning operation (may be a file, sub file, LUN or the sub LUN of the NetApp Unified Storage), and percentage completion for each of the running cloning operation.
Failed operations	Indicates the number of clone operations that have failed during the last measurement period.	Number	Cloning may fail due to insufficient disk space, permission issues etc., This failure information will be stored in a metadata file in the disk and have to be manually cleared. If the metadata file has been cleared during a measure period, this measure will be zero even if a cloning failure had occurred prior to the file getting cleared during the same measure period. The detailed diagnosis shows the Operation ID, UUID of the cloned volume, type of the cloning operation (may be a file, sub file, LUN or the sub LUN of the NetApp Unified Storage), reason for the failure, error code, and the percentage completion for each failed cloning operation.
