Information About Cisco Performance Monitor

Overview of Cisco Performance Monitor

Cisco Performance Monitor enables you to monitor the flow of packets in your network and become aware of any issues that might impact the flow before it starts to significantly impact the performance of the application in question. Performance monitoring is especially important for video traffic because high quality interactive video traffic is highly sensitive to network issues. Even minor issues that may not affect other applications can have dramatic effects on video quality.

Because Cisco Performance Monitor uses similar software components and commands as Cisco NetFlow and Cisco Flexible NetFlow, familiarity with these products will help you to understand how to configure Cisco Performance Monitor. These products provide statistics on packets flowing through a router and are the standard for acquiring IP operational data from IP networks. They provide data to support network and security monitoring, network planning, traffic analysis, and IP accounting. For more information about Cisco NetFlow and Cisco Flexible NetFlow, see the documents listed in the Additional References section.

For more information about the design, configuration, and troubleshooting of Performance Monitor and other Cisco Medianet products, including a Quick Start Guide and Deployment Guide, see the Cisco Medianet Knowledge Base Portal, located at http://www.cisco.com/web/solutions/medianet/knowledgebase/index.html.

Prerequisites for Configuring Cisco Performance Monitor

The following prerequisites must be met before you can configure Cisco Performance Monitor:

IPv4 Traffic

  • The networking device must be configured for IPv4 routing.
  • One of the following must be enabled on your router and on any interfaces on which you want to enable Cisco Performance Monitor: Cisco Express Forwarding or distributed Cisco Express Forwarding.

Configuration Components of Cisco Performance Monitor

To configure Cisco Performance Monitor, configure many of the same basic elements that you normally configure for Flexible NetFlow:

  • Interface
  • Policy
  • Class
  • Flow monitor
  • Flow record
  • Flow exporter

The figure below shows how these elements are related to each other. The elements at the bottom of the figure are configured first.

Figure 1 Cisco Performance Monitor Components


As shown above, a policy includes one or more classes. Each class has a flow monitor associated with it, and each flow monitor has a flow record and an optional flow exporter associated with it. These elements are configured in the following order:

  1. Configure a flow record to specify the key and non-key fields that you want to monitor. This is configured using match and collect commands. You can also optimally configure a flow exporter to specify the export destination. For Cisco Performance Monitor, you must configure a performance-monitortype flow record.
  2. Configure a flow monitor that includes the flow record and flow exporter. For Cisco Performance Monitor, you must configure a performance-monitortype flow monitor.
  3. Configure a class to specify the filtering criteria using the class-map command.
  4. Configure a policy to include one or more classes and one or more performance-monitortype flow monitors using the policy-map command. For Cisco Performance Monitor, you must configure performance-monitortype policies.
  5. Associate a performance-monitortype policy to the appropriate interface using the service-policy type performance-monitorcommand.

Data That You Can Monitor Using Cisco Performance Monitor

You can monitor the following information by configuring a flow record with collect or match commands for the corresponding non-key fields:

SNMP MIB Support for Cisco Performance Monitor

Cisco Performance Monitor provides support for the use of the industry-standard Simple Network Management Protocol (SNMP) to monitor media streams. This support is implemented with the addition of the following Cisco proprietary SNMP Management Information Base (MIB) modules:

  • CISCO-FLOW-MONITOR-TC-MIB--Defines the textual conventions common to the following MIB modules.
  • CISCO-FLOW-MONITOR-MIB--Defines the framework that describes the flow monitors supported by a system, the flows that it has learned, and the flow metrics collected for those flows.
  • CISCO-RTP-METRICS-MIB--Defines objects that describe the quality metrics collected for RTP streams, similar to those described by an RTCP Receiver Report packet (RFC 3550).
  • CISCO-IP-CBR-METRICS-MIB--Defines objects that describe the quality metrics collected for IP streams that have a Constant Bit Rate (CBR).

For detailed information about these MIBs, and to locate and download MIBs for selected platforms, Cisco IOS releases, and feature sets, use Cisco MIB Locator found at http://www.cisco.com/go/mibs .

This feature also includes two new command-line interface (CLI) commands and one modified CLI command. The commands are as follows:

  • snmp-server host --Enables the delivery of flow monitoring SNMP notifications to a recipient.
  • snmp-server enable traps flowmon --Enables flow monitoring SNMP notifications. By default, flow monitoring SNMP notifications are disabled.
  • snmp mib flowmon alarm history --Sets the maximum number of entries maintained by the flow monitor alarm history log.

For more information about these commands, see the Cisco IOS Master Command List .

How to Configure Troubleshoot and Maintain Cisco Performance Monitor


Note


Many of the Flexible NetFlow commands, keywords, and arguments used in used in these tasks are available in previous releases. For more information about these existing Flexible NetFlow commands, keywords, and arguments, refer to the Cisco IOS Flexible NetFlow Command Reference.

Configuring a Flow Exporter for Cisco Performance Monitor

Flow exporters are used to send the data that you collect with Cisco Performance Monitor to a remote system such as a NetFlow Collection Engine. Flow exporters use user datagram protocol (UDP) as the transport protocol and use the Version 9 export format.

To configure a flow exporter for the flow monitor, in order to export the data that is collected by Cisco Performance Monitor to a remote system for further analysis and storage, perform the following optional task. For Cisco Performance Monitor, flow exporters are configured the same way as they are configured for Cisco IOS Flexible NetFlow. For more information. see Configuring Data Export for Cisco IOS Flexible NetFlow with Flow Exporters.


Note


Each flow exporter supports only one destination. If you want to export the data to multiple destinations, you must configure multiple flow exporters and assign them to the flow monitor.

Configuring a Flow Monitor for Cisco Performance Monitor

The basic concepts for configuring a flow monitor for Cisco Performance Monitor are the same as flow monitors for Flexible NetFlow. Each flow monitor has a separate cache assigned to it and requires a record to define the contents and layout of its cache entries.

When you configure a flow monitor, you must use either:

  • An existing flow record that you configured
  • One of the following default predefined records:
    • The default RTP record (default-rtp)
    • The default TCP record (default-tcp)
    • Flexible NetFlow's "NetFlow IPv4 original input"

Note


To modify a flow record, you must remove it from all flow monitors it is associated with.

Troubleshooting Tips

To check the configuration and status of your flow policy, use the show policy-map type performance-monitorcommand.

Configuring a Flow Policy for Cisco Performance Monitor Without Using an Existing Flow Monitor

The basic concepts and techniques for configuring a class for Cisco Performance Monitor are the same as for any other type of class. The class specifies which flow monitor is included. The only significant difference is that, for Cisco Performance Monitor, the policy-mapcommand includes type performance-monitor.

If you do not already have a flow monitor configured or do not want to use any of your existing flow monitors for a new class, you can configure it under the class configuration mode, by specifying which flow record and flow exporter are included.

Table 2 show performance monitor status and show performance-monitor history Field Descriptions

Field

Description

history bucket number

Number of the bucket of historical data collected.

counter flow

Number of flows collected.

counter bytes

Total number of bytes collected for all flows.

counter bytes rate

Average number of bytes processed by the monitoring system per second during the monitoring interval for all flows.

counter bytes rate per flow

Average number of bytes processed by the monitoring system per second during the monitoring interval for each flow.

counter bytes rate per flow min

Minimum for the average number of bytes processed per second for each flow.

counter packets

Total number of IP packets processsed for all flows.

counter packets rate per flow

Avrage number of IP packets processed by the monitoring system per second during the monitoring interval for each flow.

counter packets dropped

IP packet drops by monitoring system for this flow.

routing forwarding-status reason

Forwarding status is encoded using eight bits with the two most significant bits giving the status and the six remaining bits giving the reason code.

Status is either unknown (00), Forwarded (10), Dropped (10) or Consumed (11).

The following list shows the forwarding status values for each status category.

Unknown

  • 0

Forwarded

  • Forward 64
  • Forwarded Fragmented 65
  • Forwarded not Fragmented 66

Dropped

  • Unknown 128
  • Drop ACL Deny 129
  • Drop ACL drop 130

  • Terminate For us 195

interface output

Outgoing interface name.

interface input

Incoming interface name.

monitor event

Bit 1 indicates that one of the thresholds specified by a react statement for the flow was crossed at least once in the monitoring interval. Bit 2 indicates that there was a loss-of-confidence in measurement.

ipv4 dscp

IPv4 differentiated services code point (DCSP).

ipv4 ttl

IPv4 time-to-live (TTL).

application media bytes counter

Number of IP bytes from media applications processed for a specific media stream.

application media packets counter

Number of IP packets from media applications processed for a specific media stream.

application media bytes rate

Average media byte rate (Bps) for all flows during the monitoring interval.

application media bytes rate per flow

Average media byte rate (Bps) for each flow during the monitoring interval.

application media bytes rate per flow min

Minimum rate of application media bytes, in Bps, collected per flow.

application media bytes rate per flow max

Maximum rate of application media bytes, in Bps, collected per flow.

application media event

Bit 1 is not used. Bit 2 indicates that no media application packets were seen, in other words, a Media Stop Event occured.

transport rtp flow count

Number of RTP flows collected.

transport rtp jitter mean

Mean deviation of the difference in packet spacing at the receiver compared to the sender for a pair of packets.

transport rtp jitter minimum

Minimum deviation of the difference in packet spacing at the receiver compared to the sender for a pair of packets.

transport rtp jitter maximum

Maximum deviation of the difference in packet spacing at the receiver compared to the sender for a pair of packets.

transport rtp payload type

Code for the payload format. Payload type codes can be defined dynamically or codes for default audio and video format can be used as defined in RFC 3551. An RTP source can change the payload type during a session, but a receiver MUST ignore packets with payload types that it does not understand. Therefore, some measurements taken during monitoring may not be accurate.

transport event packet-loss counter

Number of loss events (number of contiguous sets of lost packets).

transport event packet-loss counter min

Minimum number of packet loss events.

transport event packet-loss counter max

Maximum number of packet loss events.

transport packets expected counter

Number of packets expected.

transport packets lost counter

Number of packets lost.

transport packets lost counter minimum

Minimum threshold for the number of packets lost.

transport packets lost counter maximum

Maximum threshold for the number of packets lost.

transport packets lost rate

Rate of packets lost, in percent .

transport packets lost rate min

Minimum threshold for the percent of packets lost.

transport packets lost rate max

Maximum threshold for the percent of packets lost.


Displaying the Performance Monitor Cache and Clients

To display the cache and the clients for Cisco Performance Monitor, perform the following optional task.

SUMMARY STEPS

1.    enable

2.    show performance monitor cache [policy policy-map-name class class-map-name][interface interface name]

3.    show performance monitor clients detail all


DETAILED STEPS
Step 1   enable

The enable command enters privileged EXEC mode (enter the password if prompted).



Example:
Router> enable
Router#
Step 2   show performance monitor cache [policy policy-map-name class class-map-name][interface interface name]
