Introduction

This document outlines best practices for a successful deployment of Cisco ® Unified Service Statistics Manager (SSM). It documents the initial deployment and ongoing operational environments.
This document is not an alternative to the installation guide or the user guide, as it does not cover all the features and functions of the product. It is a supplement to the installation guide and the user guide. Detailed steps are provided for best practices wherever relevant.

Product Overview

Cisco Unified Service Statistics Manager, which is part of the Cisco Unified Communications Management Suite, provides advanced statistics analysis and reporting capabilities for Cisco Unified Communications deployments. Cisco Unified Service Statistics Manager 8.7 is an easy-to-use web-based software product that features a variety of advanced reports for executive, operations, and capacity planning functions. Cisco Unified Service Statistics Manager provides ready-made reports as well as customizable reports that provide visibility into key metrics including call volume, call quality, resource utilization, and capacity across the Cisco Unified Communications System, including across multiple Cisco Unified Communications Manager (formerly known as Cisco Unified CallManager) clusters, gateways, and related devices. It helps enable users to view information based on network, service, business, and user criteria and to define service-level agreement (SLA) constructs as well as to measure and verify them based on collected Unified Communications statistics. Customizable report templates and automatic report invocation and scheduling provide users with a great deal of flexibility.
Cisco Unified Service Statistics Manager 8.7 can be deployed for statistics analysis and reporting for small, medium-sized, and large Cisco Unified Communications deployments. Cisco Unified Service Statistics Manager 8.7 integrates with and relies on the data collection capabilities of Cisco Prime Unified Operations Manager (UOM) 8.7 and Cisco Prime Unified Service Monitor (USM) 8.7; the latter two products are prerequisites for the deployment of Cisco Unified Service Statistics Manager 8.7. For small and medium-sized deployments (generally up to 10,000 Cisco Unified IP phones), Cisco Unified Service Statistics Manager 8.7, Cisco Prime Unified Service Monitor 8.7, and Cisco Prime Unified Operations Manager 8.7 may be deployed on the same Windows-based server/workstation. For larger deployments, it is recommended that Cisco Prime Operations Manager 8.7 be run on a separate server. Figure 1 shows a sample deployment.

Service Statistics Workflow

Figure 2. Cisco Unified Service Statistics Manager Workflow

Cisco Unified Service Statistics Manager uses the short-term wealth of operational data collected from Cisco Prime Unified Operations Manager and Cisco Prime Unified Service Monitor to perform long-term analysis and reporting (Figure 2). It is therefore mandatory to have Unified Operations Manager and Unified Service Monitor operational prior to deploying Unified Service Statistics Manager.
Service Statistics Manager has the following components:

Service Statistics Manager server: The primary component of Service Statistics Manager. It hosts the database and web interface. It is responsible for talking to remote Service Statistics Manager agents and gathers data from Cisco Prime Unified Operations Manager and Cisco Prime Unified Service Monitor.

Service Statistics Manager agent: Sends data to the Service Statistics Manager server for data mining. Required to be running in all Cisco Prime Unified Operations Manager and Cisco Prime Unified Service Monitor servers.

SSM web user interface: Primary user interface for viewing reports, graphs, and SLAs and for administering the dial plan, call quality, and so on.

SSM administration console: Java console for administering users, groups, and agents. Uses Java Remote Method Invocation (RMI) to communicate with the Service Statistics Manager server. A maximum limit of four instances of the administration console can be installed and used to manage Service Statistics Manager.

Preinstallation Tasks

Server Requirements

• The hardware configuration needed to operate Cisco Unified Service Statistics Manager at different scalability levels and the client requirements are detailed in the Quick Start Guide for Cisco Unified Service Statistics Manager available at http://www.cisco.com/en/US/products/ps7285/prod_installation_guides_list.html.

Hardware requirements for installing Service Statistics Manager on a system with Operations Manager and Service Monitor are provided in the Coresident Guidelines section in the Installation Guide for Cisco Prime Unified Operations Manager 8.7 (Includes Service Monitor).

Postinstallation Tasks

Integrating with Operations Manager and Service Monitor

• This section assumes that installation procedures as specified in the Quick Start Guide (installation guide) have been completed.

The Quick Start Guide for Cisco Unified Service Statistics Manager provides a checklist (Table 10, Configuration Checklist) of installation procedures. Make sure that the installer has checked all the items on the checklist (for example, things to do in Cisco Prime Unified Operations Manager and Cisco Prime Unified Service Monitor - make sure Cisco Voice Transmission Quality is turned on, make sure that Cisco Prime Unified Operations Manager polling is being done and displayed for desired statistics, and so on) before using Cisco Unified Service Statistics Manager.
After Cisco Unified Service Statistics Manager has been installed, integration with Operations Manager and Service Monitor will have to be configured. To accomplish this:
1. Log in to the Cisco Unified Service Statistics Manager GUI through Error! Hyperlink reference not valid., where hostname is the name of the machine running SSM. See Figure 3.

Figure 38. SLA Capacity Trends Report

Troubleshooting

Note: Cisco Unified Service Statistics Manager collects data from Cisco Prime Unified Operations Manager and Cisco Prime Unified Service Monitor. Ensure that Operations Manager and Service Monitor (optional) are running first and are operational prior to troubleshooting Service Statistics Manager.

Service Statistics Manager could run separately on its own server (standalone mode), or it could run on the same server with Operations Manager and Service Monitor (coresident mode).
If Service Statistics Manager is running in standalone mode, make sure to install Service Statistics Manager Agents in the Operations Manager and Service Monitor servers. Service Statistics Manager Agent is installed automatically if deployed in coresident mode.
Service Statistics Manager log files are located in <Install Directory>\pw\pronto\logs\. It is recommended to zip and forward these logs when opening a Cisco Technical Assistance Center (TAC) service request.

Installation Failing

• Service Statistics Manager Installer automatically checks for system requirements prior to the start of installation. This is to help ensure that the target server complies with Service Statistics Manager's minimum system requirements.

• The TCP ports listed in Table 1 are in use by Service Statistics Manager and must be available and exempted from firewall inspections.

The following logs are useful when troubleshooting Service Statistics Manager installation issues: <Install Directory>\pw\pronto\bin\SSMPreinstall.log, proactivenet_server_install.log and proactivenet_agent_install.log

Logon Failure

• Check whether Cisco Prime Unified Operations Manager is reachable from Cisco Unified Service Statistics Manager. Try launching the Operations Manager web interface from the Service Statistics Manager server; that is, open a browser to http://CUOM:1741.

• Check whether the Service Statistics Manager agent is running in the remote Operations Manager server. Windows Control Panel > Services > Agent must be running.

• Check whether the Operations Manager admin password has been changed. To synchronize the Operations Manager password with Service Statistics Manager, run <Install Directory>\pw\pronto\bin\ runjava scripts.ssm.UpdateOMPassword. The script will ask for the new Operations Manager password. Then restart Service Statistics Manager from Start > Programs > SSM > Stop/Start shortcuts.

• Check the Service Statistics Manager log file at \pw\pronto\logs\ProactiveNet.log. If the log file shows multiple SSL handshake errors, run this script at \pw\pronto\bin\ConfigureSSMToSSLOM <CUOM_IP_Address>. Then restart Service Statistics Manager.

Autodiscovery

• Make sure that the Operations Manager IP address and password are correct and that the Service Statistics Manager agent is running on that remote Operations Manager server.

• If Monitor Types are not getting created, make sure Performance Polling is enabled in Operations Manager. On how to enable performance polling in Operations Manager, refer to http://www.cisco.com/en/US/partner/docs/net_mgmt/cisco_unified_operations_manager/2.3/user/guide/cfgPT.html#wp1546763.

• If call volume and call quality monitors are not getting created, check whether Service Monitor is configured in Operations Manager > UC Management tab > Service Monitor.

• If new devices are added in Operations Manager or Service Monitor, make sure to rerun discovery from Service Statistics Manager.

• To further troubleshoot autodiscovery issues, enable Service Statistics Manager detailed logging by running the following in the command line: pw debug -p jserver -s SSMAutoDiscovery. Log files will be stored in the \pw\pronto\logs\Debug folder.

Data Collection Failure

• Check whether Service Statistics Manager processes are still running. Run \CUSSM\serverstatus.bat. If Service Statistics Manager processes are not in the running state (that is, are stopped), you may restart Service Statistics Manager.

• Check whether Operations Manager and Service Monitor are operational. Try rediscovering Operations Manager and make sure discovery succeeds.
