Lync Monitoring

Lync Monitoring

The Lync monitoring role gathers data from Lync endpoints, servers and Lync phones. The data specifies media quality and usage data and stores them in a SQL database. The server also provides access to the data trough a reporting engine.

Requirements

To deploy the monitoring role requires a server (hardware and software spec as per all other Lync roles). A full edition of SQL server is required, which can be the same server as the backend of an Enterprise pool. Message Queuing is required on the monitoring server.

Collocation

The monitoring role can be co-located with the Archiving role. Full details on collocation can be found here.

Capacity

One Monitoring server can be associated with multiple pools. A single Monitoring server can capture data for 250,000 users. Based on the Lync Server user model, the CDR database grows 31.5 KB per user per day, and the QoE database grows 28 KB per user per day.

The Monitoring server database size can be calculated from the following formula

DB size = (DB growth per user per day) * (Number of users) * (Number of days)

Installation

The Monitoring role comprises a number of components:

Data Collection Agent - automatically installed on all FE servers
Monitoring server - collects data sent by FE via Message Queuing and stores it in the database
SQL database - QoEMetrics Schema details and LcsCDR Schema details
Message Queuing - installed on Monitoring server as well as FE server
SCOM management pack (optional)
Monitoring Server Reports (optional)

Installation requires:

Iinstalling and configuring MQ
deploy SQL and SQl Reports Service
define Monitoring roles in the Lync Topology and publish
Install Lync Monitoring servers
Install Monitoring Server reports

SQL 2008 Std/Ent SP1

You can use the following cmdlets to configure Monitoring Server:

To configure CDR settings, use New-, Set-, Get- and Remove-CsCdrConfiguration.
