Built-In Metrics

This section describes the NetIM built-in metrics and consists of the following topics:

• “WMI-Specific Built-In Metrics" (including SharePoint-related metrics)

“Deprecated” means that a feature is functional but no longer considered a preferred solution, and is scheduled for removal from the product in a future release.

Descriptions of Built-In Metrics

The following tables list the built-in metrics that NetIM can poll, organized by group and metric class. Additional metric classes can be defined by the user. For more information, see Defining a Metric Class Using the User-Defined Metrics Wizard For details about user-defined classes, contact the NetIM administrator.

For each metric, the tables lists the following information:

• Metric name

• Description

• Units (if any)

• Alertable (whether the metric can be used to trigger alerts)

See “Retention Schemes" to understand how metrics data are consolidated for each metric class.

Interface Status

This metric class contains metrics giving the up or down status of interfaces, and is used to compute “Interface Availability".To collect this metric class using WMI, you must provide WMI credentials with administrative privileges.

timestamp	Time of metric data retrieval.	milliseconds	No
Administrative Status	Administrative status (up, down, or testing).		Yes
Operational Status	Operational status (up, down, or testing).		Yes
Output Queue Length	Length of the output packet queue.	packets	Yes

The Interface Status metric class includes a derived metric called Interface Status. The Interface Status metric is derived from the SNMP OIDs Interface Administrative Status (ifAdminStatus) and Interface Operational Status (ifOperStatus). The purpose of the Interface Status metric is to simplify the 3 states of ifAdminStatus and 7 states of ifOperStatus into 3 simplified states of Up(1), Down(2), and AdminDown(3). The up/down status of the Interface Status metric is meant to indicate whether an interface is administratively configured to be up and is operationally able to pass packets. The Interface Status metric can be used for alerting and is calculated as shown in the following table:

Administrative Status	Operational Status	Interface Status
Up(1)	Up(1)	AdminUp-OperUp(1)
Up(1)	Down(2) \| Testing(3) \| Unknown(4) \| Dormant(5) \| NotPresent(6) \| LowerLayerDown(7)	AdminUp-OperLogicallyDown(2)
Down(2)	Up(1)	AdminDown(3)
Down(2)	Down(2) \| Testing(3) \| Unknown(4) \| Dormant(5) \| NotPresent(6) \| LowerLayerDown(7)	AdminDown(3)
Testing(3)	Up(1)	AdminDown(3)
Testing(3)	Down(2) \| Testing(3) \| Unknown(4) \| Dormant(5) \| NotPresent(6) \| LowerLayerDown(7)	AdminDown(3)

The Interface status metric is one component of NetIM’s Interface Health calculation. Only interfaces that are administratively configured to be up participate in the interface health calculation. Further, only interfaces in the AdminUp-OperLogicallyDown(2) state are in an unhealthy state (Default Alert Major category) because they are configured to be up but are unable to pass packets, as shown in the Alerts wizard:

duration	Time difference between successive metric data retrievals.	milliseconds	No
Timeout	Specifies the duration to wait for a RTT operation completion. The value of this object cannot be set to a value that would specify a duration exceeding rttMonCtrlAdminFrequency. For connection-oriented protocols, this might cause the connection to be closed by the probe. closed, it will be assumed that the connection reestablishment will be performed. To prevent unwanted closure of connections, be sure to set this value to a realistic connection timeout.	milliseconds	No
Jitter Interval	Inter-packet delay between packets. This object is applicable only to jitter probe.	milliseconds	No
Packet Data Request Size	Number of octets to be placed into the ARR Data portion of the request message, when using SNA protocols.
