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 "Data Sources" section on page 3-10.

NAM 4.1 can support a maximum of at least 1,500 data sources.

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).

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. (Available only on NAM-1 and NAM-2.)

Switch engine module (Supervisor) records received by the NAM. You can select any combination of Port statistics, VLAN statistics, and NBAR statistics. (Available only on NAM-1 and -NAM-2.)

Router engine module records (Router) received by the NAM. You can select any combination of Interface statistics and NBAR statistics. (Available only on the NME-NAM.)


Note Data sources persist across all Monitor windows. For example, if you select VLAN2 as a data source, then go to another Monitor window, VLAN2 will be displayed there if it is configured for that collection. If the previously selected data source is not configured for collection on the new Monitor window, the NAM displays the default data source for that window.


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 have 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 within these three VLANs.

You must specify a collection data source for this collection. The data source could be VLAN 1, VLAN 2, or VLAN 3.

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 on page 6-3.

 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.

Table 4-3 Auto-Discovered Protocol Types

Protocol Type
Displays As...

Ether2

ether2-ether-type number

SNAP

snap-ether-type number

IP

ip-protocol type number

TCP

tcp-port number

UDP

udp-port number

SUNRPC

sunrpc-program number



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 New Protocol" section on page 3-70. 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.

Monitoring Response Time Data

NAM 4.1 monitors TCP packet flow between client and server and measures response time data to provide more visibility into application response times (ART) and network latency. NAM 4.1 response time monitoring provides end-to-end response times and to help you locate possible network and application delays.


Note NAM 4.1 does not support IPv6 for response time monitoring.


You can set up the NAM to measure network round trip time (RTT), client response time, server response time, and total transaction time to improve application performance. Figure 4-39 shows the various points in network packet flow where the NAM gathers data and the trip times you can monitor.

Figure 4-39 NAM Application Response Time Measurements

Figure 4-40 shows a representation of total transaction time as opposed to application response time.

Figure 4-40 Transaction Time versus Response Time Measurements

Table 4-40 lists and describes the ART metrics measured by NAM 4.1.

Table 4-40 Application Response Time Metrics 

Metric
Description

Response Time (average)

Response Time is the amount of time it takes a server to send the initial response to a client request as seen by the NAM. This is the initial server think time. Increases in the response time usually indicate problems with server resources, such as the CPU, Memory, Disk, or I/O due to a lack of necessary resources or a poorly written application.

Response Time (minimum)

Response Time (maximum)

Number of responses

Total number of responses observed during the monitoring interval

Number of late responses

Total number of responses that exceed the Max Response Time; see Setting Up Response Time Configuration, page 3-61.

Number of responses by response time

7-bucket histogram; see Setting Up Response Time Configuration, page 3-61.

Client Bytes

Number of TCP bytes sent from a client during the monitoring interval.

Server Bytes

Number of TCP bytes sent from a server

Client Packets

Number of TCP packets sent from a client

Server Packets

Number of TCP packets sent from a server

Number of connections (new sessions)

Number of TCP connections (new sessions) made during the monitoring interval.

Completed Sessions

Number of TCP connections closed

Refused Sessions

Number of TCP connections refused by a server

Unresponsive Sessions

Number of times a server does not reply to TCP SYN requests within a timeout period

Session Duration

Average duration of the TCP sessions

Application Delay (AD) - average

AD is the time it takes a server application (for example, a web server application) to respond to a request. AD is the time between the client request arriving at the server application and the first response being returned by the application.

Application Delay - minimum

Application Delay - maximum

Network Delay (ND) - average

The network round trip (flight time) between a client and a server through the NAM switch or router. ND is equal to the sum of CND and SND. The network round trip (flight time) between a client and a server through the NAM switch or router. ND is equal to the sum of CND and SND. NAM measures the ND using TCP 3-way handshakes. If there are no new TCP connections made during the monitoring interval, this metric is not reported.

Network Delay - minimum

Network Delay - maximum

Client Network Delay (CND) - average

CND is the network round trip time (or flight time) between a client and the NAM switch or router.

In WAAS monitoring, CND from a WAE client data source represents the network RTT between the client and its edge WAE, while CND from the WAE server data source represents the WAN RTT (between the edge and core WAEs).

Client Network Delay - minimum

Client Network Delay - maximum

Server Network Delay (SND) - average

SND is the network round-trip time between a server and the NAM switch or router.

In WAAS monitoring, CND from a Server data source represents the network RTT between the server and its core WAE.

Server Network Delay - minimum

Server Network Delay - maximum

Total Delay (TD) - average

TD is the total amount of time from the first packet of a client request until the client receives the first response packet from the application server. Total Delay (TD) is the sum of the Network Delay (ND) and the Application Delay (AD).

Use TD with care because it is not measured directly and mixes the response time metric (SRT) with the connection metric (CND).

Total Delay - minimum

Total Delay - maximum

Total Transaction Time - average

Total amount of time from the first packet of a client request until the client receives the final response packet from the server. TTT is a key indicator for detecting application performance anomalies.

Transaction times might vary depending upon application types. Relative thresholds are useful in this situation.

Total Transaction Time - minimum

Total Transaction Time - max

Number of Transactions

The number of transactions completed during the measurement interval.

Data Transfer Time - average

Average elapsed time from the first server-response packet to the last server-response packet, excluding retransmission time. Data transfer time is always measured in the server-to-client direction and can be used to detect problems for a particular type of transaction of an application.

Number of Packets Retransmitted

Number of TCP packets retransmitted during the monitoring interval. (The metric for the client-to-server direction is not provided.)

Number of Bytes Retransmitted

The number of retransmitted server-to-client bytes. (The metric for the client-to-server direction is not provided.)

Retransmission Delay - average

Average time to retransmit lost packets per transaction.

Round Trip Time (RTT)

Average round trip time for the client to acknowledge (ACK) a server TCP packet.

Time (ms) elapsed from the start of a client request to the completion of server response. Transaction times might vary significantly depending upon application types. Relative thresholds are useful in this situation.

Transaction time is a key indicator when detecting application performance anomalies.

App Response Time

Amount of time it takes a server to send the initial response to a client request as seen by the NAM.

Data Transfer Time

Time from the first server-response packet to the last server-response packet, excluding retransmission time. Data transfer time is always measured in the server-to-client direction and can be used to detect problems for a particular type of transaction of an application.

Average Retransmission Time

Average inter-packet time intervals started by retransmitted packets from server to client in each transaction, measured at server-site.

Bytes Retransmitted

The number of retransmitted server-to-client packets.

Packets Retransmitted

The number of retransmitted server-to-client bytes.

Round Trip Time

Time elapsed from a server-to-client packet to its client-to-server acknowledgement in each transaction. Round trip time is a key indicator for network-caused problems. Check WAN interface utilization, CND, and SND to isolate the problem.

Number of Round Trips

Number of times a server-to-client packet or client-to-server acknowledgement occurs in each transaction.

Connections
(New Sessions)

Number of TCP connections (new sessions) made during the monitoring interval.

Completed Sessions

Number of TCP connections closed

Refused Sessions

Number of TCP connections refused by a server

Unresponsive Sessions

The number of TCP connections unresponsive during the measurement interval, this metric indicates a WAN problem if client-site measurement is significantly large than the server-site measurement. Useful to compare client-side measurements with server-side measurements.

Session Duration

Average duration of the TCP sessions.

Viewing MPLS Traffic Statistics

When data packets containing MPLS tag are spanned to the NAM, the traffic can be monitored by the tag inside the data packet. This feature is especially useful in a network that deploys MPLS/VPN where each VPN is uniquely identified by an MPLS tag. When NAM encounters stacked MPLS tags, only the relevant inner-most tag is used for monitoring.
