Cisco IOS Voice Troubleshooting and Monitoring -- Configuring Voice Performance Statistics on Cisco Gateways

From DocWiki

Latest revision as of 18:42, 16 October 2012

This article contains the following procedures:

• Configuring the Duration and Time Periods of Call Statistics on the Gateway (required)
• Configuring the Gateway to Collect Signaling Statistics (required)
• Configuring the Gateway to Collect VoIP AAA Accounting Statistics (required)
• Configuring the FTP Server to Enable Archiving of Statistics from the Gateway (optional)

Note:

If you need to obtain statistical information since reboot, the configuration should be stored in NVRAM before you restart the gateway.

Summary of Configuration Tasks

There are two general areas of configuration-one for the collection of signaling statistics and one for the collection of accounting statistics. The tasks required will depend on whether you configure the gateway to collect signaling statistics only, accounting statistics only, or both signaling and accounting statistics.

Required Task for Collection of All Call Statistics

Configure the duration or time period for when call statistics are collected on the gateway. See the Configuring the Duration and Time Periods of Call Statistics on the Gateway.

Required Task for Signaling Statistics

Configure the gateway to support the collection of signaling statistics. See the Enabling the Gateway to Collect Signaling Statistics.

Optional Task for Signaling Statistics

Configure the call statistics record signaling parameters, changing the default values as needed. See the Configuring the Minimum Call Duration and Signaling Thresholds

Required Tasks for Accounting Statistics (Configured in This Order)

1. Configure the gateway to support the collection of accounting statistics. See the Enabling the Collection of VoIP AAA Accounting Statistics on the Gateway.
2. Configure accounting on the gateway. Refer to the gw-accounting aaa command configuration in the Voice Configuration Library.
3. Specify that the accounting update is new information. Refer to the aaa accounting update new-info command configuration in the Cisco IOS Security Configuration Guide, and the Cisco IOS Security Command Reference.
4. Define the AAA RADIUS server group. Refer to the aaa group server radius command configuration in the Cisco IOS Security Configuration Guide, and the Cisco IOS Security Command Reference.
5. Define a designated broadcast accounting server group (accounting acknowledge broadcast command). See the Configuring a Designated Server Group for a Broadcast Method List.
6. Define the RADIUS server host, port, key, and vendor specific attributes (VSAs). Refer to the Cisco IOS Security Configuration Guide, and the Cisco IOS Security Command Reference.

Optional Tasks for Both Signaling and Accounting Statistics (Configured in Any Order)

Configure the FTP server or syslog server download. See the Configuring the Gateway to Archive Statistics to an FTP Server and the Configuring the Gateway to Archive Statistics to a Syslog Server.

Note:

Before configuring the gateway to archive statistics to an FTP server, you must first configure the FTP server to support the archiving process. See the Configuring the FTP Server to Enable Archiving of Statistics from the Gateway.

Configuring the Duration and Time Periods of Call Statistics on the Gateway

Before you configure the gateway to collect call signaling statistics, VoIP AAA accounting statistics, or Cisco VoIP internal error codes (IECs), you must first configure the duration and time periods for when the call statistics are collected. There are three methods for collecting call statistics: periodic, since the last reset, and for specific times.

Note:

These interval methods are mutually exclusive, meaning that the gateway can be configured for only one collection interval at a time. The collection interval configured applies to all call statistics collected. For example, if you configure the collection interval for a periodic interval, and you configure the gateway to collect both signaling and VoIP AAA accounting statistics, then both types of statistics will be collected on the periodic basis.

To configure the duration and time period of when call statistics will be collected on the gateway, see one of the following sections:

• Configuring the Gateway to Collect Call Statistics on a Periodic Basis
• Configuring the Gateway to Collect Call Statistics Since the Last Reset
• Configuring the Gateway to Collect Call Statistics for a Specific Time Interval

Displaying the Signaling Statistics for Each Aggregation Level

Signaling statistics can be collected and displayed for all aggregation levels. To display signaling statistics for the different aggregation levels, see the following sections:

• Displaying Signaling Statistics for All Aggregation Levels
• Displaying Gateway-Level Signaling Statistics
• Displaying VoIP-Level Signaling Statistics
• Displaying PSTN-Level Signaling Statistics
• Displaying Trunk-Group Level Signaling Statistics
• Displaying Voice-Port Level Signaling Statistics

All commands in this section are entered in privileged EXEC mode. The statistics displayed are based on the time range configured using the voice statistics time-range command. For example, if you set the time range to specify that the gateway collects statistics only since the last reset, then these displays show only the statistics since the gateway was last reset or rebooted.

With these commands, you can specify that the display shows either verbose or concise information. The verbose display shows all fields contained in the call statistics records, while the concise display shows only output that contains total calls, answered calls, and answered call duration. The verbose display mode is enabled by default.

In addition, you can specify that the gateway push the statistics display from the console to an FTP or syslog server. To configure the gateway to support pushing statistics to an FTP or syslog server, see the Managing the Collection of Voice Statistics.

Configuring the Gateway to Collect VoIP AAA Accounting Statistics

Using this feature, statistics can be collected to tally accounting records on billing servers (RADIUS) and on voice gateways based on call legs (both inbound and outbound). The statistics collected track whether calls were successfully accounted for based on the acknowledgement messages from designated billing or accounting servers.

This section shows you how to configure the collection of accounting statistics on the gateway. This section documents the following tasks:

• Enabling the Collection of VoIP AAA Accounting Statistics on the Gateway
• Configuring a Designated Server Group for a Broadcast Method List
• Disabling the Collection of VoIP AAA Accounting Statistics
• Displaying the VoIP AAA Accounting Statistics
• Clearing the VoIP AAA Accounting Statistics

Prerequisites

The definition of the AAA method list for accounting, the server groups, and the RADIUS servers should be configured. For more information, refer to Configuring AAA for Cisco Voice Gateways.

Restrictions

You can define "pass" criteria for calls on the basis of method lists but not on the basis of server groups. For broadcast method lists, if the gateway attempts to access multiple server groups simultaneously, additional configuration is needed. See the Configuring a Designated Server Group for a Broadcast Method List.

Note: To enable the collection of both accounting and signaling statistics on the gateway, enter the command without the accounting keyword, as follows: voice statistics type csr.
4.	voice statistics accounting method method-list-name pass {start-interim-stop | start-stop | stop-only} Example: Router(config)# voice statistics accounting method h323 pass stop-only	Configures the method-list pass criteria. Note: The method-list-name argument is the same as that configured using the method command in gateway-accounting AAA configuration mode. You can have multiple method lists configured on a gateway at one time.
5.	voice statistics max-storage-duration {day value| hour value | minute value} Example: Router(config)# voice statistics max-storage-duration minute 60	(Optional) Configures the maximum storage time in system memory of the gateway. The keywords and argument are as follows: day-Number of days. The value argument has a valid range from 0 to 365. hour-Number of hours. The value argument has a valid range from 0 to 720. minute-Number of minutes. The value argument has a valid range from 0 to 1440. Note: This command also applies to the collection of VoIP internal error codes (IECs).
6.	voice statistics display-format separator {space | tab | new-line | char char} Example: Router(config)# voice statistics display-format separator new-line	(Optional) Specifies the way in which displayed information is separated. The default is a comma (,).
7.	exit Example: Router(config)# exit	Exits global configuration mode.

Configuring a Designated Server Group for a Broadcast Method List

This task is required if accounting CSRs need to be collected for a gateway that is configured for a broadcast method list. See Configuring the Gateway to Collect VoIP AAA Accounting Statistics. It is possible to set all the server groups in a method list for monitoring acknowledgements.

Prerequisites

The collection of accounting statistics should be enabled on the gateway. The pass criteria for the method list must already be defined.

SUMMARY STEPS

1. enable
2. configure terminal
3. aaa group server radius name
4. accounting acknowledge broadcast
5. end
6. show voice statistics | begin aaa group server

DETAILED STEPS

 Router> enable   

 Router# configure terminal   

 Router(config)# aaa group server radius billing-grp   

 Router(config-sg-radius)# accounting acknowledge broadcast   

 Router(config-sg-radius)# end   

 Router# show voice statistics | begin aaa group server   

Troubleshooting Tips

Acknowledgements of only designated server groups are considered when deciding whether the accounting for a given call leg is successful. If more than one server group is configured as designated, the gateway considers the response from all server groups in deciding whether the call leg accounting is successful.

Disabling the Collection of VoIP AAA Accounting Statistics

4.	exit Example: Router(config)# exit	Exits global configuration mode.

Displaying the VoIP AAA Accounting Statistics

After the gateway has been configured to collect VoIP AAA accounting statistics, you can display all accounting statistics or accounting statistics for a specific method list.

All commands in this section are entered in privileged EXEC mode. The statistics displayed are based on the time range configured using the voice statistics time-range command. For example, if you set the time range to specify that the gateway to collect statistics only since the last reset, then these displays will show only the statistics since the gateway was last reset or rebooted.

With these commands, you can specify that the gateway push the statistics display from the console to an FTP or syslog server. To configure the gateway to support pushing statistics to an FTP or syslog server, see the Managing the Collection of Voice Statistics.

Troubleshooting Tips for VoIP AAA Accounting Statistics

If any of the following messages is displayed, proceed with the solution shown.

• Message: "Either specific or periodic time-range has existed."

Solution: Delete any previously configured specific or periodic time range.

• Message: "Ending time must be greater than starting time."

Solution: Make sure that the configured end time is later than the start time for the time range configured.

• Message: "Starting time must be future time."

Solution: Make sure that the configured start time is in the future.

If accounting statistics are not being collected properly, the best place to start troubleshooting is by verifying your configurations as follows:

Router# show running-config | include voice statistics
voice statistics type csr
voice statistics accounting method h323 pass stop-only 
! Specifies the pass criteria.
voice statistics time-range since-reset
Router# show running-config | include aaa
aaa new-model
aaa accounting connection h323 start-stop group radius 
! Specifies the method list.
aaa session-id common
gw-accounting aaa 
! Enables accounting on the gateway.
radius-server host 1.6.10.203 auth-port 1645 acct-port 1646 
! Specifies RADIUS server IP address.

If your configurations are correct, turn on debugging with the following debug commands and check the output. You must turn on all three commands:

• debug isdn q931
• debug radius accounting
• debug voip-aaa

As long as accounting and signaling statistics are being collected, the output from these three debug commands will display on the console.

The following sample output shows that the accounting statistics are not being properly collected by the RADIUS server:
