Overview
Chapter 1: netapp 1.1 9
Overview
The NetApp filer also know as NetApp Fabric-Attached Storage (FAS) is a type of disk storage device which owns and controls filesystems, directories, and files present over the network. The NetApp filer uses the Data ONTAP operating system (based on FreeBSD).
NetApp Filers can offer the following:
■ Supports SAN, NAS, FC, SATA, iSCSI, FCoE and Ethernet all on the same platform
■ Supports either SATA, FC and SAS disk drives
■ Supports block protocols such as iSCSI, Fibre Channel and AoE
■ Supports file protocols such as NFS, CIFS , FTP, TFTP and HTTP
■ High availability
■ Easy Management
■ Scalable
The NetApp probe uses the Simple Network Management Protocol (SNMP) to communicate with storage arrays. The probe uses SNMP to discover local and remote NetApp systems. The probe runs specific SNMP queries and extracts the important information from the devices. You can define alarms to be raised and propagated when specified thresholds are breached.
Monitoring Capabilities
Some of the components you can monitor using the NetApp probe:
■ General Product information and System Statistics
■ Cluster status
■ Disk
■ Ethernet interface
■ Aggregates
■ Volumes
■ vFiler
■ SnapMirrors
■ SnapVaults
■ Qtree
■ Quotas

You can add or edit QoS definitions as follows:
■ To edit an existing QoS definition, double-click on it either in the hierarchy on the left, or in the table on the right.
■ To define a new QoS definition, right-click the QoS node in the left pane and choose New QoS from the menu.
Working with Monitors
Chapter 1: netapp 1.1 25
Either way, this action launches the QoS Definition dialog, which contains the following fields:
Name
The name of the QoS definition.
Group
The group the definition belongs to.
Description
Descriptive text about the QoS definition
Unit
The units of the measurement fully spelled out.
Unit Abbreviation
A useful abbreviation for the units of the measurement.
Has Maximum Value
The value will not exceed the given maximum. This sets the maximum value on an axis when the value is graphed.
Working with Monitors
There are three different ways to enable monitors to be measured NETAPP elements:
■ Manually selecting the monitors
This is done by navigating through the hierarchy appearing under agent node. When you select a folder in the hierarchy on the left, the monitors for it are listed on the right. Simply select the ones you want to monitor. See also the section Manually Selecting Monitors to be Measured.
■ Using templates
Templates are a useful for defining monitors to be measured on multiple NetApp systems. See the section Using Templates for further information.
■ Using Auto Configurations
Auto Configurations provide a powerful method for automatically adding monitors to be measured. "Auto Monitors" will be created when new devices come on line, with no need for you to reconfigure the NetApp probe to monitor them.
Example: When new disks are added to the NetApp system, the Auto Configuration feature, if configured, creates Auto Monitor(s) for the new disks and automatically starts monitoring them.
See the section Using Auto Configuration for further information.
Working with Monitors
26 netapp Guide
Manually Selecting Monitors to be Measured
To select a monitor to be measured for a resource, simply select the agent in the left pane and browse the hierarchy appearing under the agent node. Select a folder in this hierarchy to list the associated monitors on the right. Then select the ones you want to monitor.
To Edit Monitor Properties for SNMP Monitor
You can double click the on monitor to open the Monitor Properties dialog.
Working with Monitors
Chapter 1: netapp 1.1 27
This screen contains three sections:
■ Monitor properties
■ Value Properties
■ Active
The Monitor properties section contains the following fields:
Name
This is the name of the monitor. The name will be inserted into this field when the monitor is created, but you are allowed to modify the name.
Type
Displays the type of checkpoint. This field is enabled while configuring Custom Monitors.
Object Identifier (OID)
The Variable name in the format of an Object Identifier
Formula
Displays the formula used to calculate This field is enabled while configuring custom monitors.
Description
This is a description of the monitor. This description will be inserted into this field when the monitor is created, but you are allowed to modify it.
The Value Properties section contains the following fields:
Definition
Defining which value to compare to the threshold value:
Automatic (based on type):
The value is automatically set based on variable type (integer, counter etc.).
When Automatic is chosen, the probe – based on data type— either fetches the current value or makes a delta calculation.
For the following data types a delta calculation is performed: counter32 and counter64.
For all other data types, the current value is fetched.
The current value:
Uses the current (last measured) value
The delta value (current – previous):
Uses the delta value, which is the difference between the current and the previous measured value. Note: The main window displays a 3-second delta computation.
Working with Monitors
28 netapp Guide
Samples
Sampling defines normalized value for a performance object to be monitored.
By default, the sampling process is not enabled. The samples box is also not available. To perform the sampling process, select the Calculate average based on check box. The samples box becomes available, which displays default samples set in the General Setup Properties dialog. For example, in the following image, it is six.
You can change the number of samples. Enter a value other than zero or one in the samples box, to override the default sample value for any variable. This value has higher precedence than the default value of the number of samples, set in the General Setup Properties dialog for a probe.
If you enter number of samples equal to one, then sampling process is not performed. As a result, average value of the variable samples is not calculated.
Similarly, if you enter number of samples equal to zero, then sampling is not calculated. Next time when you open the Variable dialog, it displays the default number of samples.
You cannot keep the samples box blank. The OK button becomes unavailable if you keep the number of samples blank.
Calculate value using ratio
Select this check box to multiply the variable value with a number (ratio):
E.g. a ratio of 0, 1 (value * 0, 1) means 10 % of the value. Enter the ratio value in the box.
Force the variable value as a numeric value type
Select this option to force the probe to treat a data type as a numeric value.
E.g. The string:"2.5" will be treated as the numeric value 2.5 if this option is ticked.
The Active section activates the monitoring of the probe and contains the following fields:
Enable Monitoring
Selecting this option activates the monitoring.
Note that the monitor will also be selected in the list of monitors in the right window pane when this option is selected, and that you can enable/disable monitoring of the checkpoint from that list.
Rule / Extend Rule tabs
These tabs are activated when the option Enable Monitoring is selected (see above).
The fields on these tabs define the alarm and QoS conditions for the variable.
You have the option to use one or two levels of alarm triggering rules:
Working with Monitors
Chapter 1: netapp 1.1 29
You define a set of alarm triggering rules on the Rule tab and alternatively also a set of additional alarm triggering rules on the Extended Rule tab.
See the EXAMPLE later in this table.
IMPORTANT: Rule has to trigger before the extended rule is checked.
Note also that the Extended Rule tab is disabled if selecting the operator = in the Rule tab.
Operator
Select from the drop-down list the operator to be used when setting the alarm threshold for the measured value. Generally speaking, exact equalities are not useful for values that vary with time.
Example:
=> 90 means alarm condition if the measured value is above 90.
= 90 means alarm condition if the measured value is exactly 90.
Threshold
The alarm threshold value. An alarm message will be sent if this threshold is exceeded.
Alarm severity level
The severity level of the alarms issued when the specified threshold value is breached. You may choose between five severity levels (from Information to Critical).
Message String
Select the alarm message to be issued if the specified threshold value is breached. These messages are kept in the message pool. The messages can be modified as noted in the Managing Messages section.
Note that you can use variables message string to create a message that provides an operator with specific information about the condition.
Using variables is simple: as you type in the Message String, at the point where you want to use a variable, enter a dollar-sign ($). A dialog pops up with the available variables.
Advanced tab Subsystem ID
Allows you to define a subsystem ID on the NAS), which is included in the alarm message.
Advanced tab Message String On Clear
Allows you to define your own message to be issued when an alarm is cleared. This message overrules the default message.

Creating custom monitors
You can only create and edit custom monitors. Perform the following steps to create a custom monitor.
1. In the tree view, navigate to the Custom Monitor.
2. Right-click in the right-hand pane and select New Monitor option from the context menu.
Working with Monitors
34 netapp Guide
Following fields are enabled while creating Custom Monitors. For rest of the fields, please refer To Edit Monitor Properties Section.
Type
Enter the Type of Checkpoint you want to monitor.
Type has following values:
Static: Target OID where no Dynamic Indexing is required
Example: System Time Up
Static + Formula: Static checkpoint where formula is involved
Dynamic: Target OID where Dynamic Indexing is required
Example: Disk Usage
Dynamic + Formula: Dynamic checkpoint where formula is involved
Object Identifier (OID)
The Variable name in the format of an Object Identifier
Formula
Provide the formula to get the OID values in desired format.
For Example: If you have 2 OID’s having No 1 and 2 and if you require the sum of its values then you can simply specify
$1+$2.
Similarly, you can use any mathematical formulas to get the desired result.
Working with Monitors
Chapter 1: netapp 1.1 35
Specify the Dynamic Index Tracking details if the OID you want to monitor changes index.
Note: These fields will be enabled only when you are creating Custom Monitor in which Type selected is Dynamic or Dynamic + Formula
You should look for a value in a specified SNMP MIB Table and use the index of the entry that matches a specific value.
If you have the required MIBs loaded, you may specify the "MIB Table" using the symbolic (textual) form. Alternatively, you can use the numerical form (e.g., .1.3.6.1.2.1.2.2.1.2 that translates to IF-MIB: ifDescr).
The following are valid symbolic forms for the OID .1.3.6.1.2.1.2.2.1.2:
■ IF-MIB::ifDescr
■ ifTable.ifEntry.ifDescr
■ ifDescr
The probe will do a snmpwalk of the specified table, and search for the specified value. The comparison of values is case insensitive. The index found for the value match will be used as the index for the specified OID when doing the snmpget operation.
The Index will be updated on each poll interval. First, the last known Index is tried. If there is no match anymore (i.e. value has changed), the probe does a snmpwalk of the specified SNMP MIB table and updates the Index with a new one (if the specified value can be found at another index).
You can use the "Test" button to check the current Index and to confirm whether you have specified a valid MIB Table and/or value to search.
The probe GUI has no restrictions on entering invalid values.
Note: Use the Missing OID Alarm in order to receive alarms, which indicate that the OID cannot be found (i.e. OID is missing).
Using Templates
Templates are useful tools for defining monitors to be measured on the various elements of a NetApp system:
You may create templates and define a set of monitors belonging to that template. These templates can be applied to a folder or element by dragging and dropping the template on the node in the tree where you want to measure the monitors defined for the template. You may also drop a template on a resource in the tree structure, and the template will be applied to all elements for the resource.
Working with Monitors
36 netapp Guide
To Create a Template
You can create a Template in following manner:
■ Right click the Templates node in the browser pane, and choose New Template from the menu.
In the resulting Template Properties dialog, specify a Name and a Description for the new template.
Note that you can also edit an existing template: Select one of the templates defined under the Templates node in the browser (left-side) pane, right-click it, and select Edit from the menu.
Working with Monitors
Chapter 1: netapp 1.1 37
Applying Default Templates to the Profile
If you want the probe to apply the default monitoring templates provided with the probe to the new profile:
1. Click the Default Templates Settings button.
The Default Templates Settings dialog opens containing a list of all the default templates.
2. Select the check box for the templates that you want the probe to apply to the new profile. Clear the check box for the templates that you want the probe to remove from the new profile.
Note:
■ A default template named NetApp Basic Monitors is selected by default. This monitor is applied even if you do not click the Default Templates Settings button while creating a new profile. Clear the checkbox to remove this default template from the profile.
■ The Apply to auto configuration checkbox allows the probe to add the selected default templates to the Auto Configuration node. This check box is selected by default. Clear this check box if you do not want to add the selected templates to the Auto Configuration node.
3. Click OK. The selected default templates are added to the new profile.
Working with Monitors
38 netapp Guide
To Add Monitors to the Template
To add a monitor (checkpoint) to a template, drag it from the right pane and drop it on the template in the left pane.
You can then edit the properties for the monitors in the template, as described in the To Edit Monitor Properties section.
Working with Monitors
Chapter 1: netapp 1.1 39
To Apply a Template to a NetApp System
Drag and drop the template onto the NetApp system in the Agent hierarchy. This assigns the monitors defined in template to the corresponding NetApp components.
You can drag and drop the template onto auto configuration node to apply relevant dynamic monitors in the template to be Automonitors. See the section Using Auto Configuration for further information.
Working with Monitors
40 netapp Guide
Using Auto Configurations
Auto Configurations provide a powerful method for automatically adding monitors to be measured. Auto Monitors will be created for devices that are currently NOT monitored.
Example:
When new Disks are added to the NetApp system, the Auto Configuration feature will, if configured, create Auto Monitor(s) for the new Disks and automatically start monitoring them.
The Auto Configuration feature consists of two nodes located under the resource node in the left pane:
■ Auto Configurations
One or more checkpoints (or templates) can be added to this node, using drag and drop. When this is done, you must click the Apply button and restart the probe to activate the changes.
The probe will search for the appropriate types of objects. Auto Monitors, representing the monitor(s)/template(s) added under the Auto Configuration node will be created (and listed under the Auto Monitor node, see below) for devices that are currently NOT monitored.
NOTE: Adding many monitors/templates to the Auto Configurations node may result in a very large number of Auto Monitors (see below).
■ Auto Monitors
This node lists Auto Monitors created for previously unmonitored devices, based on the contents added to the Auto Configuration node. The Auto Monitors will only be created for devices that are currently NOT monitored.
You can add or edit Auto Configurations as follows:
■ To edit an existing Auto Configuration, double-click it either in the hierarchy on the left or in the table on the right and choose Edit from the menu.
■ To define a new Auto Configuration, right click the Auto Configuration node in the left pane, and choose New Auto Configuration from the menu.
Either way, this action launches the Monitor Properties dialog. For details about this dialog, see the To Edit Monitor Properties section.
This dialog lets you define auto configurations for any type of object.
