5 Chapter 1: Monitoring Cisco BTS Softswitches Using the ehealth System Broadband Telephony Services Softswitches Broadband Telephony Services (BTS) Softswitches (software switches) provide call-control and service intelligence telephony. A softswitch also serves as a platform for interfacing applications and enhanced service platforms. Softswitch networks carry voice, video, and data traffic more efficiently than existing hardware circuit switches. The ehealth Suite offers support for the Cisco BTS Softswitch. You can monitor Cisco BTS Softswitches using the ehealth system to ensure that your service performs as expected. When performance does not meet expectations, run ehealth reports to help pinpoint the cause of the problem. Cisco BTS Softswitch The Cisco BTS Softswitch provides call-control intelligence for establishing, maintaining, routing, and terminating voice calls. It interacts with enhanced converged voice-and-data services, and application platforms such as voice mail and unified messaging. Three main components comprise the Cisco BTS Softswitch: Call Agent - Serves as a call management system and media gateway controller. All Cisco BTS Softswitch systems use multiple call agents to handle capacity and redundancy requirements. Element Management System (EMS) - Assists the provisioning, administration, reporting, and billing features of the Cisco BTS Softswitch. The EMS is a mediation device between a network management system (NMS) and one or more call agents. Feature Server - Provides an open protocol and flexible framework to introduce new features into a network. It provides various basic telephone service and Centrex, tandem, and Advanced Intelligent Network (AIN) services to the calls controlled by the call agents.

6 License and Software Requirements License and Software Requirements ehealth provides support for Cisco BTS Softswitches running software version Each Softswitch element consumes one universal poller license. Cisco BTS Softswitches are discovered as applications. When you begin the discovery process, select the Application technology in the Discover window. Element Overview The Cisco BTS Softswitch monitors the following element types: BTS VoIP Softswitch- Represents the softswitch as a whole. Call Processing - Contains processing statistics for calls handled by the BTS Softswitch. Announcement Server - Contains announcement server statistics. SIP Processing - Contains Signaling Interface Adaptor related statistics on the Service Initiation Protocol (SIP). Trunk Group Set - Contains usage information on individual Trunk Groups associated with the Cisco BTS Softswitch. Trunk Group - Organizes Trunk Group elements and provides Trunk Group At-a-Glance reports for the performance of the group. ehealth uses the following conventions for naming elements: Element Type BTS VoIP Softswitch Call Processing Announcement Server SIP Processing ehealth Element Name Convention sysname-ah-bts sysname-ah-bts-callprocessing-componentid sysname-ah-bts-announcement-componentid sysname-ah-bts-sip-componentid Trunk Group Set sysname-ah-bts-trunkgroupset Trunk Group sysname-ah-bts- TrunkGroup-componentID-TrkGrpType- TrkGrpID Note: If the default SNMP port number is 161, the port number will not appear in the name. 6 Monitoring the Cisco BTS Softswitch User Guide

7 Element Overview Figure 1 Cisco BTS Softswitch Data Model Live Exceptions Monitoring ehealth offers the Live Exceptions profile BTS Unusual Workload to monitor Cisco BTS Softswitches. The BTS Unusual Workload profile uses Deviation from Normal alarm rules to indicate unusually low or high usage attempts. This can indicate traffic and connection problems. You can apply this profile to ehealth groups (or group lists) that contain Cisco BTS Softswitch elements to raise alarms for unusual workloads.

9 Chapter 2: Reporting Reports ehealth reports provide historical and current information regarding the performance of your entire infrastructure. The following reports can be used to monitor your Cisco BTS Softswitches: At-a-Glance Trend Top N These reports give you the insight necessary to optimize IT performance, plan proactively, recognize trends, and identify potential problems. At-a-Glance Reports At-a-Glance reports contain a set of pre-defined charts that provide insight into the performance of elements. You can use At-a-Glance reports to compare variables on a single page and look for combinations of problems that could indicate problem sources. The following table identifies the At-a-Glance charts that gauge the performance of each Cisco BTS Softswitch element over a specified time period. Element Type Announcement Server Charts Address Incomplete/sec Authorization Code Invalid/sec Call Rejected/sec Cause Unknown/sec Circuit Unavailable/sec Destination Out of Order/sec Directory Number Changed/sec Facility Rejected/sec Feature Not Subscribed To/sec HNPA Area Code/sec No Route to Destination/sec Reporting 9

This enables you to review the performance of related elements. Sample At-a-Glance Report This sample At-a-Glance report displays the three charts for a Call Processing element. The top two charts show the success and failure rate for the total originating and terminating calls per second. The third chart shows the total of both attempts over a 24-hour period by calls attempted and abandoned. If, for example, the number of calls abandoned is too high, this might suggest a potential problem that needs further investigation. 10 Monitoring the Cisco BTS Softswitch User Guide

11 Reports Trend Reports Trend reports allow you to view more granular data on a particular performance variable or set of variables for one or more elements, or for a group of elements. You can view trends over time using both At-a-Glance and Trend reports. When you run a Trend report for an element, select up to 10 variables. You can observe how the variable values change behavior over time, and determine when the changes occur. For directions to access the most current list of available Trend and Top N variables to choose for each element, refer to Trend and Top N Variables on page 13. Reporting 11

12 Reports Sample Trend Report This sample Trend report is a multi-variable report that highlights the performance of three variables on a Call Processing element. These variables are divided by time. Top N Reports Top N reports provide information on groups of elements. These reports use the same variables as Trend reports, but in addition they offer variables such as peak values. When you run Top N reports, select a group of elements and the variables that you want ehealth to compare for each element in that group. Elements are listed in ascending or descending order based on the value of the first variable. Sample Top N Report When you run a Top N report, select a group of elements for which you want to view common values, and then select up to six variables for comparison. This sample Top N report displays the common values for two variables (percentage of originating failed calls and the total originating calls per second) across four elements in the selected group. 12 Monitoring the Cisco BTS Softswitch User Guide

13 Reports Trend and Top N Variables You can use the ehealth Element Variable Report (available from the ehealth Web interface Organization Page) to obtain details about supported Trend and Top N variables for the Cisco BTS Softswitch elements. This sample Element Variable Report shows the Trend variables for a Call Processing element. It illustrates how ehealth combines and evaluates the MIB variables to obtain the data for each Trend variable. Reporting 13
