Getting Started with Cisco Prime Unified Service Monitor


Cisco Prime Unified Service Monitor (Prime USM) is a product from the Cisco Prime Unified Communications Management Suite that receives and analyzes Mean Opinion Scores (MOSs) from Cisco Prime Unified Communications Manager (Unified Communications Manager) clusters and sensors—Cisco 1040 Sensors (Cisco 1040s) and Cisco Network Analysis Modules (NAMs)—sending traps when violations occur.


NoteThroughout this document, any reference to Unified Communications Manager can also be understood to refer to Cisco Prime Unified CallManager, unless explicitly noted.

Prime USM documentation refers you to Common Services features and documentation when they are applicable. Common Services documentation and online help mention CiscoWorks LAN Management Solution and its components, which are products that can be installed elsewhere in your network. Common Services documentation also mentions LMS Portal, LMS Setup Center, and other features that are not applicable to Prime USM.


The following topics are included:

Note For information on initially configuring Prime USM, see Configuration Checklists and Tips.


Overview

Prime USM obtains and analyzes MOS from sensors (Cisco 1040s and NAMs) and Unified Communications Manager clusters. Prime USM supports sensors or clusters or both. For more information, see Data Collection and Analysis.

Prime USM analyzes the data that it receives and sends traps when MOS falls below a threshold. Prime USM provides a set of default global thresholds, one per supported codec. Prime USM enables you to change the default global thresholds and to override them by creating threshold groups: sensor threshold groups and cluster threshold groups. For more information, see Thresholds and Traps and Trap Receivers.

Prime USM diagnostic reports display data for calls that occurred during the data retention period (see Configuring and Viewing Other Settings). You can run reports for CVTQ data and sensor data. You can also run reports for the endpoints with the greatest number of violations in a 24-hour or 7-day period. For more information, see Using Reports.

To further analyze, display, and act on Prime USM data, you can use Cisco Prime Unified Operations Manager (Operations Manager), by configuring it as a trap receiver for Prime USM. Operations Manager can generate events for Prime USM traps, display the events on the Service Quality Alerts dashboard, and store and display event history. For more information, see User Guide for Cisco Prime Unified Operations Manager 9.0.

Data Collection and Analysis

Prime USM receives and analyzes MOS from these sources when they are installed in your voice network and configured properly:

Sensors—Cisco 1040s and NAMs compute MOS for each Real-Time Transport Protocol (RTP) stream. Prime USM obtains data at 60-second intervals, as a result of:

Receiving syslog messages that Cisco 1040s send

Polling NAMs for data

CVTQ—Unified Communications Manager collects data from endpoints that support K-factor; MOS is calculated on the endpoints using the CVTQ algorithm. At the termination of a call, Unified Communications Manager stores the data in Call Detail Records (CDRs) and Call Management Records (CMRs).


Note For endpoints that support K-factor and for Unified Communications Manager versions that Prime USM supports, see Cisco Prime Unified Service Monitor 9.0 Compatibility Matrix.


Table 1-1 provides a high-level comparison among the data sources that Prime USM uses. Detailed procedures for performing related tasks are provided throughout this document.

Thresholds and Traps

Prime USM examines the data it receives and compares MOS against the applicable threshold from user-defined threshold group settings or global threshold settings. When MOS drops below the threshold, Prime USM generates SNMP traps and sends them to up to four trap receivers.

You can set thresholds for the following:

Sensor Groups—Select sensors and endpoints and set a MOS threshold value for one or more supported codecs.

CVTQ Groups—Select Unified Communications Manager clusters and endpoints and set a MOS threshold value for one or more supported codecs.

Global Settings—Update default thresholds for one or more supported codecs. Global threshold settings are used when no other thresholds are applicable.

Prime USM also sends a trap when a sensor is unreachable and another when the same sensor becomes reachable again.

Trap Receivers

Prime USM examines the data it receives, comparing MOS against a default or user-specified threshold value for the codec. When MOS drops below the threshold, Prime USM generates SNMP traps and sends them to up to four trap receivers.

Prime USM also stores the call data it receives (from clusters and sensors) in the database for a configurable number of days. (See Report Data Retention Period in Configuring and Viewing Other Settings.) Optionally, Prime USM also stores the call data it receives from sensors to disk files. (See Setting Up the Cisco 1040 Sensor Default Configuration.)

You can configure Cisco Prime Unified Operations Manager (Operations Manager) as a trap receiver for Prime USM. Operations Manager can further analyze, display, and act on Prime USM data. Operations Manager can:

Generate events for Prime USM traps

Display the events on the Service Quality Alerts dashboard

Store and display event history

About Enterprise and MSP Deployment Modes

Prime USM 9.0 can be installed in either of the following modes, based on your requirements:

Enterprise Network Deployment mode

Managed Service Provider (MSP) Network Deployment mode

You can specify the mode when you install the product.


Note In MSP Network Deployment mode, Operations Manager and Service Monitor need to coreside on the same machine, that is, Operations Manager and Service Monitor must be installed on the same virtual or physical machine. MSP Network Deployment mode is not applicable for standalone installations of Service Monitor.


In both modes, Service Monitor always works with a unique Operations Manager instance, where both Operations Manager and Service Monitor manage the same set of Unified Communications Managers.

MSP Network Deployment mode enables you to view and manage multiple customers from a single Operations Manager instance in a service provider deployment. You can perform tasks either across multiple customers or for a single customer.

Prime USM collects and reports CDRs and CMRs from multiple Call Managers. Multiple-customer view support restricts views and actions based on user authorization for the Call Managers that are present in Service Monitor.

Using role-based access control (RBAC), Operations Manager 9.0 provides the ability to authenticate and authorize users based on System Defined Groups used to customize the clusters, applications, and devices per customer.

Customer names defined in Operations Manger are visible in Prime USM. Users logged in with the permission to view the clusters for a customer in Operations Manger can view the same clusters in Prime USM. Users are restricted to viewing and executing only what is allowed for their role. See About RBAC for more details on RBAC.

Prime USM displays the customer name wherever applicable. When Prime USM is installed in MSP Network Deployment mode along with Operations Manager, the Service Monitor home page shows the list of customers managed under the Customer link at the top-right of the home page. See User Guide for Cisco Prime Unified Operations Manager 9.0 for more details on MSP Network Deployment mode and multi-customer views.

In a network deployment where NAT-enabled devices exist, Service Monitor does not need to be configured specially for NAT. As long as Service Monitor works with a coresident or coexistent Operation Manager instance, Service Monitor will be able to monitor the clusters for which NAT is in use. See User Guide for Cisco Prime Unified Operations Manager 9.0 for more details.


Note Cisco 1040 Sensor and NAM are not supported in MSP Network Deployment mode.


About RBAC

Role Based Access Control (RBAC) is a built-in feature in Common Services. Operations Manager 9.0 and Prime USM 9.0 use the RBAC feature to achieve user role-based authentication and authorization to access groups of devices.

You can create device groups and assign users to roles in Operations Manager, via Common Services. The user roles created via Common Services are common to both Operations Manager and Prime USM.

Service Monitor mapping of roles to tasks is shared with Operations Manager. This enables you to do either of the following:

View the tasks assigned to a role

Select tasks when you create new user roles.

When you create new users via Operations Manager, you can view and select the list of Prime USM tasks along with other Operations Manager tasks. When Operations Manager and Prime USM are on the same server, DCR synchronization is automatic, because the Common Services database is shared.

Prime USM supports the following user roles:

Super Admin—All privileges of Network Administrator and System Administrator roles.

System Administrator

Network Administrator

Network Operator

Help desk

See Permissions Report (Administration > Server Administration (Common Services) > Reports > Permissions Report) for a list of task to role mapping.

We recommend that you configure security using Cisco Secure ACS, in Enterprise deployment mode.

The following additional information is available:
