Use the More and Fewer buttons to get the correct number.
Note: The Fewer button will remove the last criteria you added.
The criteria are set as an AND condition. To change this, define a User Class. Contact ATI support for examples of user
class files on the AlliedView NMS Server.
4. Under Collection Statistics, select the Add radio button, and fill in the fields as described in the following table.
Note: Choosing the type and location of data from the MO is done through the MO’s agent, which is the program
that receives and processes the data request, and the Object Identifier (OID), which is the unique number
that identifies that characteristic for the MO.The list of OIDs is retrieved from the MIB definition of the
device. To view the OIDs for a device, use the MIB Browser tool.

Normally the Data identifiers are lengthy. For the identifiers that have in common the starting n digits, you
can specify that as prefix. For example, assume two Statistics, IfSpeed and IfinOctect. The corresponding
Data identifiers are
.1.3.6.1.2.1.2.2.1.5.1 and .1.3.6.1.2.1.2.2.1.10.1.
You can see the first part .1.3.6.1.2.1.2.2.1 is common to both, so you can specify the common prefix as
.1.3.6.1.2.1.2.2.1. Even if you do not specify the prefix, Performance module will add the prefix to the
identifier.
Default
Polling
Interval
The time interval for periodic data collection. For example, if set to 5, then for all the Data identifiers, data
will be collected once in every 5 seconds. Default value: 300 seconds.
Name Any meaningful string for the Data identifier. Required
OID A unique Object Identifier string that represents a MIB entry. Data is collected for this identifier. An
SNMP-specific Data identifier is called an OID. For example . 2.2.1.16.1 refers to IfInOctects interface
instance 1. Required.
Type This can be set to interface, node, multiple, or none.
Node - Used when Data identifier is of type Scalar. If you choose the type to be Node you must specify the
full OID. For example to collect data for Interface_in_octets instance 1 then choose this type and specify
the data identifier as 2.2.1.10.1.
Interface - Exclusively for IF table entries of RFC 1213 MIB, only. This is used when the data identifier
has many instances.When you want to collect data for all the instances of an OID choose the type to be
Interface. Enter the data identifier as 2.2.1.10. For every instance of the OID, a PolledData will be created.
Multiple - This type can be used to collect data for OIDs that have multiple instances. As Interface type is
specific to IF table entries for other OIDs that have multiple instance you can choose the type as Multiple.
Only one PolledData will be created for the OID specified but data collection will be done for all the
instances.
None - Used when other protocols are used for data collection apart from SNMP.
Default value: None.
Polling
Interval
The time interval for periodic data collection. For e.g. if set to 2, it indicate that for all the Data identifiers,
data will be collected once in every 2 seconds. Default: 300 seconds.
Active If you uncheck the checkbox, data collection will be temporarily stopped for this Data identifier. To
resume data collection you will have to check this checkbox. Default: True (checked).
