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.

IPv6 Traffic

  • Cisco Express Forwarding must be enabled on your router and on any interfaces on which you want to enable Cisco Performance Monitor. You can use the ipv6 cef command to enable 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-monitor type flow record.

  2. Configure a flow monitor that includes the flow record and flow exporter. For Cisco Performance Monitor, you must configure a performance-monitor type 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-monitor type flow monitors using the policy-map command. For Cisco Performance Monitor, you must configure performance-monitor type policies.

  5. Associate a performance-monitor type policy to the appropriate interface using the service-policy type performance-monitor command.

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 .

Limitations for the Catalyst 6500 Platform

Cisco Performance Monitor has the following limitations on the Catalyst 6000 platform:

  • There are some limitations on which types of interfaces can be monitored. The next two tables list which types of interfaces are supported for ingress and egress monitoring on the Catalyst 6500 platform.

  • Performance monitoring on VRFs is not supported.

  • Performance monitoring of multicast flows is supported on the ingress direction.

  • Routed traffic from a trunk port on a VLAN interface cannot not be monitored because it is not possible to identify the source VLAN interface for the traffic. You will see the following syslog message: “Routed traffic from trunk ports will not be monitored by ingress policy on VLAN interface.”

    For a workaround, you can configure a performance monitoring policy on a trunk interface. This monitoring will result in additional CPU usage.

  • You cannot use match all type Class maps. Only match any type of lookups are supported. If you configure performance monitoring to use match-all type class maps, it will result in the cloning of packet to the CPU. Packets will then again be classified in the CPU when match-all classes are properly applied and packet are dropped if required. This causes higher than expected CPU usage.

  • Performance monitoring policy on the egress of a VLAN interface will not monitor traffic getting bridged within the VLAN. This is due to hardware limitation. Workaround is to apply the policy at the ingress of VLAN interface as well as egress. Policy on the ingress of the VLAN interface will monitor bridged packets.

  • Cloned packets from Egress policies can only be software rate-limited. No hardware-based protection is available for these packets. Therefore, you might see high interrupt CPU usage during scenarios when many flows are being monitored.

  • Egress performance monitoring makes use of a recirculation mechanism on the Catalyst 6500 platform. This introduces several microseconds of additional latency to the frame switching.

  • Performance monitoring is not supported for the packets switched using the Fast (CEF) Path.

  • Lawful intercept and performance monitoring makes use of the same mechanism for cloning the packets. The Lawful Intercept feature takes precedence over performance monitoring. Therefore, performance monitoring does not function when the Lawful Intercept feature is enabled. When this occurs, a syslog message is created.

  • Performance monitoring makes use of same mechanism as other features, such as Optimized ACL logging, VACL Capture, IPv6 Copy, and so on. The feature that is enabled first takes precedence. The other features are blocked from being configured and a syslog message is created.

    When reacts (including media-stop) are configured under a performance monitoring policy and when the traffic is unstable, syslog messages are logged into the buffer and are not printed on the console screen.

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.

      Exits flow record configuration mode and returns to privileged EXEC mode.

       

      Troubleshooting Tips

      To check the configuration and status of your flow record, use the show flow record type performance-monitor command.

      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.

        (Optional) specifies whether statistics are collected for the flow monitor.

         
        Step 7 exporter exporter-name


        Example:
        Device(config-flow-monitor)# exporter export-4
         

        Specifies the flow exporter for the flow monitor.

         
        Step 8 record {record-name| default-rtp| default-tcp|netflow ipv4 original-input}


        Example:
        Device(config-flow-monitor)# record default-rtp
         

        Specifies the flow record for the flow monitor.

         
        Step 9 end


        Example:
        Device(config-flow-monitor)# end
         

        Exits flow monitor configuration mode and returns to privileged EXEC mode.

         

        Troubleshooting Tips

        To check the configuration and status of your flow monitor, use the show flow monitor type performance-monitor command and the show running-config flow monitor command.

        Configuring a Flow Class for Cisco Performance 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 the filter that determines which flow traffic to monitor. The filter is configured using various match commands in class-map mode.

        If you do not already have a flow monitor configured, you can either:


        Note


        Nested class maps are not supported. In other words, you cannot use the class-map command while in class-map configuration mode (config-cmap).

          Troubleshooting Tips

          To check the configuration and status of your flow class, use the show policy-map type performance-monitor or show class-map command.

          Configuring a Flow Policy for Cisco Performance Monitor 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-map command 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 using the flow monitor inline option and specifying which flow record and flow exporter are included.

            If no value is set but the application name is configured as a key field, then the system uses the value for the threshold that it finds in the default map. If no value is set and the application name is not configured as a key field, then the default value is used for the threshold.

            If more than one react command is configured for the same policy and class but only one of the react configurations has threshold values set, then the values of the configured react take precedence and the rest of the threshold values are ignored.

            If more than one react command is configured for the same policy and none of them have the threshold value configured, then the default threshold value is applied for the configuration with the lowest react ID.

              If no value is set but the application name is configured as a key field, then the system uses the value for the threshold that it finds in the default map. If no value is set and the application name is not configured as a key field, then the default value is used for the threshold.

              If more than one react command is configured for the same policy and class but only one of the react configurations has threshold values set, then the values of the configured react take precedence and the rest of the threshold values are ignored.

              If more than one react command is configured for the same policy and none of them have the threshold value configured, then the default threshold value is applied for the configuration with the lowest react ID.

              Device(config-pmap-c-react)# end
               

              Exits the current configuration mode and returns to privileged EXEC mode.

                  What to Do Next

                  To check the configuration and status of your service policy, use the show performance monitor statuscommand and show performance monitor historycommand.

                  Verifying That Cisco Performance Monitor Is Collecting Data

                  To verify that Cisco Performance Monitor is collecting data, perform the following optional task.


                  Note


                  Flows are correlated so that if the same policy is applied on the same input and output interface, the show command will display a single flow for the input and output interfaces and the interface name and direction for the flow are not displayed.


                  If no data is being collected, complete the remaining tasks in this section.

                  Before You Begin

                  The interface to which you applied the input flow monitor must be receiving traffic that meets the criteria defined by the original flow record before you can display the flows in the flow monitor cache.

                  where filter = {ip {source-addr source-prefix | any} {dst-addr dst-prefix | any} | {tcp | udp} {source-addr source-prefix | any} {[eq| lt| gt number| range min max| ssrc {ssrc-number | any} | {{dst-addr dst-prefix | any} eq| lt| gt number| range min max| ssrc {ssrc-number | any}}

                    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.

                        Displaying the Current Status of a Flow Monitor

                        To display the current status of a flow monitor, perform the following optional task.

                        Before You Begin

                        The interface to which you applied the input flow monitor must be receiving traffic that meets the criteria defined by the original flow record before you can display the flows in the flow monitor cache.

                        SUMMARY STEPS

                          1.    enable

                          To verify the configuration commands that you entered, perform the following optional task.

                          Before You Begin

                          The interface to which you applied the input flow monitor must be receiving traffic that meets the criteria defined by the original flow record before you can display the flows in the flow monitor cache.

                            1.    enable

                            2.    show running-config flow monitor


                          DETAILED STEPS
                            Step 1   enable

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



                            Example:
                            Device> enable
                            Device#
                            
                            Step 2   show running-config flow monitor

                            The show running-config flow monitor command shows the configuration commands of the flow monitor that you specify.

                                    Enabling Debugging

                                    To enable debugging for Cisco Performance Monitor, perform the following optional task in privileged EXEC mode.

                                    SUMMARY STEPS

                                      1.    debug performance monitor {database | dynamic | event | export | flow-monitor | metering | provision | sibling | snmp | tca | timer}


                                    DETAILED STEPS
                                    debug performance monitor {database | dynamic | event | export | flow-monitor | metering | provision | sibling | snmp | tca | timer}

                                    The debug performance monitor command enables debugging for the following performance monitor components:

                                    • Flow database

                                    • Dynamic monitoring

                                    • Performance events

                                    • Exporting

                                    • Flow monitors

                                    • Metering layer

                                    • Provisioning

                                    • Sibling management

                                    • SNMP

                                    • TCA

                                    • Timers

                                    The following example shows how to enable debugging for dynamic monitoring:



                                    Example:
                                    Device# debug performance monitor dynamic 
                                    

                                    Configuration Example for Cisco Performance Monitor

                                    Example Monitor for Lost RTP Packets and RTP Jitter

                                    This example show a configuration that monitors the number of lost RTP packets, the amount of RTP jitter, and other basic statistics for the gig1 interface. In this example, Cisco Performance Monitor is also configured to make an entry in the syslog when the any of the following events occur on the interface:

                                    • The percentage of lost RTP packets is between 5 percent and 9 percent.

                                    • The percentage of lost RTP packets is greater than 10 percent.

                                    • A media stop event has occurred.
