Overview of Data Collection and Data Sources
All statistics and monitoring data produced by the NAM are generated by various types of collections. A collection operates on a stream of packets and produces output based on the input stream. In most cases, a collection corresponds directly to MIB tables such as RMON or SMON.
The Collection Definitions table (Table 4-1) defines the different collection types.
Table 4-1 Collection Definitions
|
Collection
|
Definition
|
Corresponds
|
Host |
Examines a stream of packets; produces a table of all network addresses observed in those packets (also known as the collection data). Each entry records the total number of packets and bytes sent and received by that host and the number of non-unicast packets sent by that host. |
RMON2 nlHostTable (the actual implementation of the collection). |
Protocol |
Examines a stream of packets; produces a table of all protocols observed in those packets. Each entry indicates the number of packets and bytes observed for that protocol. |
RMON protocolDistStatsTable (the actual implementation of the collection). |
Capture |
Examines a stream of packets; produces a table of actual packet data (the captureBufferEntries). Each entry contains an exact copy of the data observed in the packet. |
RMON1 bufferTable, filterTable, and channelTable variables. |
Voice
(proprietary) |
Examines a stream of packets; produces tables of data for IP telephony-related protocols: •All IP phones observed in the packet stream. •Individual calls observed in the packet stream. •Statistics (such as jitter and packet loss) for each phone and call entry are recorded. •The worst-quality calls that were observed (determined by several characteristics). |
— |
The stream of packets on which a collection operates is called the collection data source. It might be different for each collection. The data produced by a collection is called the collection data.
Note The collection data is usually in the form of SNMP tables (except in voice collections).
The NAM can support simultaneous combinations of different collections, each operating on different collection data sources.
•The number of potential simultaneous collections is limited only by CPU and memory resources.
•The collection data sources are limited by the SPAN sources. For more information on SPAN sources, see the "Setting Up Data Sources" section.

Configuring Multiple Collections
You can configure multiple collections (such as host, conversation, protocol, ART, and voice) simultaneously on the NAM. Collections are always configured on separate data sources.
Associated with each collection is a specific collection data source that might or might not correspond directly with the SPAN/VACL traffic stream that was configured. Examples of collection data sources include:
•All packets in the SPAN/VACL traffic stream regardless of the port/VLAN or origin (ALL SPAN).
•All packets in the SPAN/VACL traffic stream on a specific
VLAN (VLAN x).
•All packets in the SPAN/VACL traffic stream that were configured to arrive on a specific NAM data port (DATA PORT 1 or DATA PORT 2).
Note These data sources are available only on the WS-SVC-NAM-2 model.
•NetFlow Data Export (NDE) records received by the NAM from either the local Supervisor engine module or other remote NDE sources (such as remote routers).
•Switch engine module (Supervisor) records received by the NAM. You can select any combination of Port statistics, VLAN statistics, and NBAR statistics.
•Router engine module records (Router) received by the NAM. You can select any combination of Interface statistics and NBAR statistics.
Individual collection instances process only those packets in the traffic streams that correspond to their configured data sources. For example, a host collection configured with a data source of VLAN 12 will not be populated with any received NDE flow records. Nor will it be populated with packets in the SPAN/VACL traffic stream that are not tagged for VLAN 12.
Similarly, a conversation collection configured with a data source specifying NDE records from a remote router will not be populated with any packets arriving in the SPAN/VACL traffic stream.
Scenario
You configured the SPAN/VACL traffic stream source to include VLANs 1, 2, and 3. You now want to start an application collection that counts the packets and bytes monitored for each application protocol.
You must specify a collection data source for this collection. The data source could be VLAN 1, VLAN 2, or VLAN 3, or any combination of the three.
If you configure the data source as VLAN 2, the collection generates statistics for those packets received on VLAN 2. However, if you were to specify VLAN 10 as the collection data source, even if VLAN 10 were a valid VLAN ID, the collection would never get populated with data because VLAN 10 was not configured as part of the SPAN/VACL traffic stream.
Note The SPAN/VACL traffic stream represents the aggregate sum of all traffic being sent to the NAM for monitoring as a result of SPAN or VACL configuration on the local Supervisor engine module. In addition to the SPAN/VACL traffic stream, one or more NDE traffic streams might be received from the local Supervisor engine module or remote switches and routers. The data source configured for a specific collection instance must correspond to traffic that appears on one of these traffic streams, or else the collection statistics will not get populated.
Each possible collection data source is represented as an ifEntry in the NAM ifTable (MIB-II). The Data Collection Sources table (Table 4-2) describes the valid collection data sources.
Table 4-2 Data Collection Sources
|
Collection Data Source
|
Limitations
|
All SPAN (aggregate SPAN/VACL traffic stream) |
If no SPAN or VACL traffic sources are configured, the collection is not populated with data. |
Specific VLAN ID |
If the VLAN was not configured as part of the SPAN/VACL traffic stream, the collection is not populated with data. |
NDE data source |
The export parameters must be configured on the device that will export the records to the NAM; otherwise, the collection is not populated with data. Monitoring is limited to a subset of NAM collection types. |
The SPAN, VACL, NDE Traffic Streams and Collection Data Sources illustration (Figure 4-1) shows the relationships between SPAN and NDE data sources and collection data sources.
Figure 4-1 SPAN, VACL, NDE Traffic Streams and Collection Data Sources
You can view real-time data from collections that were configured on the NAM. For more information on setting up collections on the NAM, see the "Configuring Capture Settings" section.

Protocol Auto Discovery
Traffic Analyzer can automatically discover up to 100 unknown protocols. The protocols are displayed according to the parent type and an identifier.
The Auto-Discovered Protocol Types table (Table 4-3) lists the type of protocols that can be automatically discovered and how they are displayed.

Note The automatically discovered protocols are not saved in NVRAM and are lost when the NAM is rebooted. To save an auto-discovered protocol, you can enter it manually into the Protocol Directory. For more information, see the "Creating a Protocol" section.
You can also clear the auto-discovered protocols without rebooting by entering the command no monitor protocol auto-learned in the NAM CLI.

NDE Flow Masks and V8 Aggregation Caches
Depending on the flow mask or aggregation configured at the device, some data fields might not be available in the NDE data structure. As a result, some windows will not display data for a NetFlow data source or will display specific conditions. The Flow Mask and Aggregation Window Conditions table (Table 4-4) lists the display conditions for the windows under the Monitor tab and the flow-mask or aggregation that causes them.
