Getting Started with Service Monitor


Cisco Unified Service Monitor (Service Monitor) is a product from the Cisco Unified Communications Management Suite that receives and analyzes Mean Opinion Scores (MOSs) from Cisco 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 Unified CallManager, unless explicitly noted.

Service Monitor 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 Service Monitor.


The following topics are included:

Overview

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

Service Monitor analyzes the data that it receives and sends traps when MOS falls below a threshold. Service Monitor provides a set of default global thresholds, one per supported codec. Service Monitor 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.

Service Monitor diagnostic reports display data for calls that occurred during the data retention period (see Configuring and Viewing Other Settings, page 3-32). 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, page 2-1.

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

Data Collection and Analysis

Service Monitor 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. Service Monitor 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 Service Monitor supports, see Cisco Unified Service Monitor 8.0 Compatibility Matrix.


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

Compatibility determination

Note For more information, see Cisco Unified Service Monitor 8.0 Compatibility Matrix.

Binary image filename—
SvcMonAB2_102.img

Network Analysis Module Software version—4.x.

NAM hardware:

NME-NAM

NAM-1/NAM-2

NAM 2200 Series Appliances

Unified Communications Manager version

Support on the voice gateway or Cisco Unified IP Phone for the CVTQ algorithm

Configuration in Service Monitor

Add TFTP server

Edit Cisco 1040 Sensor configuration files

Add credentials to Service Monitor

Configuration outside of Service Monitor

See Quick Start Guide for Cisco 1040

Copy configuration files and binary image to TFTP server

Configure http or https server and web admin user on the NAM

Configure NTP server in Network Analysis Module Software

Configure accounts and privileges on Unified Communications Manager servers

Configure parameters and application billing server in Unified Communications Manager

Data collection: Push or Pull

Push—Cisco 1040 sends syslog messages

Pull—Service Monitor polls NAMs

Pull—Service Monitor queries the Unified Communications Manager database

Push—Unified Communications Manager sends information to application billing server

MOS Calculation

Based on R-factor

4.1 or earlier—None; MOS is not calculated

4.2 and later—CVTQ algorithm (sometimes referred to as K-factor in Unified Communications Manager documentation)

Registration or Authentication

Automatic or
manual registration—
Cisco 1040 registers with a Service Monitor

Authentication—Service Monitor uses credentials to access the data source

Reports

Sensor Diagnostic Report with link to Sensor Stream Correlation window—Correlates streams from multiple sensors with call detail records (CDR)

CVTQ Diagnostic Report

CDR Call Report

Sensor Most-Impacted Endpoints

CVTQ Most-Impacted Endpoints

Thresholds

Sensor group

Note Thresholds that you configure in Service Monitor are not propagated to Network Analysis Module software. Likewise, thresholds configured in Network Analysis Module software are not propagated to Service Monitor.

CVTQ group

Note If sensor groups or CVTQ are not defined or not applicable, Service Monitor uses global thresholds.

Time Synchronization

Service Monitor sends hourly time synch to 1040s.

Strong recommendation: Configure NAM to use the NTP server that Service Monitor uses.

Must configure Service Monitor to use the NTP server that Unified Communications Manager uses.

Timing

Data is pushed or pulled every 60 seconds.

Data available after a call completes.

Thresholds and Traps

Service Monitor 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, Service Monitor 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.

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

Trap Receivers

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

Service Monitor 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, page 3-32.) Optionally, Service Monitor also stores the call data it receives from sensors to disk files. (See Setting Up the Cisco 1040 Sensor Default Configuration, page 4-3.)

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

Generate events for Service Monitor traps

Display the events on the Service Quality Alerts dashboard

Store and display event history

For more information, see User Guide for Cisco Unified Operations Manager.

Service Monitor Home Page

The Reports tab is the home page for Service Monitor, appearing after you log in. From the home page, you can generate reports that provide you with MOS statistics for a configurable number of days. For more information, see the following topics:

Starting Service Monitor


Step 1 Enter the address in your browser:

If Secure Socket Layer (SSL) is not enabled, enter http://server_name:1741 in your browser, where server_name is the DNS name or the IP address of the server where Service Monitor is installed.

If SSL is enabled, enter https://server_name:443.


Note If you changed the HTTPS port during Service Monitor installation, replace 443 with the port number that you entered during installation.
