10 UCHM overview As an IMC service component, Unified Communications Health Manager (UCHM) provides a solution for monitoring the health status of networks deployed with Microsoft Lync Server. Use it to manage network resources including the Lync Servers, PSTN gateways, and Lync client endpoints. Features UCHM provides the following features: Autodiscovery Uses a Topology Builder configuration file to search the network and add all found Lync servers and PSTN gateways to UCHM. This feature eliminates the need for manual device import and prevents import errors. Dynamic Lync client management Dynamically adds Lync endpoints for management by scanning call statistics in the QoEMetrics database. Lync call history Provides the call history and calling quality of Lync endpoints. Real-time network health monitoring Periodically sends NQA probe packets to monitor network link status, network performance, and Lync service quality in real time. UCHM displays the monitoring data in diagrams and tables. Diagnosis and troubleshooting Leverages the NQA protocol in Lync end-to-end tests for diagnosis and troubleshooting purposes.

UCHM can autodiscover new Lync servers and PSTN gateways on the network and dynamically update the Lync server list and the PSTN gateway list. Table 2 Resources you can manage and descriptions Resource Lync server PSTN gateway Lync endpoint Description Use UCHM to view, query, and delete Lync servers. When NTA and APM components are deployed, UCHM works with them to monitor bandwidth usage of the Lync servers and Lync application status. For more information, see "Managing Lync servers." Use UCHM to view, query, and delete PSTN gateways from the PSTN gateway list. For more information, see "Managing PSTN gateways." UCHM dynamically adds Lync endpoints to the Lync endpoint list, and allows operators to view, query, delete, and locate Lync endpoints. For more information, see "Managing Lync endpoints." Network real-time monitoring UCHM provides various functions to monitor in real time the health status of the networks that are running Lync services. Table 3 Network real-time monitoring functions and descriptions Network monitoring function Test tunnels Lync bad calls Description Monitors the link status between two devices by adding a test tunnel between them. UCHM uses NQA probe packets to monitor the test tunnels in real time, and displays the test results on the Test Result page. Operators can add, view, query, and delete test tunnels. For more information, see "Managing test tunnels." UCHM displays low quality Lync calls on the Lync bad call page, and allows operators to view, query, and delete Lync bad calls. For more information, see "Managing Lync bad calls." 2

12 Network monitoring function End-to-end tests Lync alarms Lync call history Description End-to-end tests use NQA probe packets to test the connectivity and call quality between two endpoints. With end-to-end tests, operators can view the topology between tested endpoints, their call history records, and call history quality information. For more information, see "Managing end-to-end tests." Based on the alarm module of the IMC Enterprise and Standard platform, UCHM provides the ability to manage alarms specifically triggered by the UCHM component. Operators can recover, acknowledge, and perform root cause analysis on the alarms. For more information, see "Managing Lync alarms." UCHM records and displays the Lync call history statistics, and allows operators to view, query, and delete Lync call history information. For more information, see "Managing Lync call history."

13 Quick start UCHM service flow When using UCHM for the first time, follow the common service flow. UCHM registration An unregistered UCHM version can be used only for 45 days since the date the service was first started. Functions of an unregistered UCHM version are the same as those of a registered UCHM version except that the autodiscovery function supports a maximum of 25 Lync servers. You can purchase a license to register your UCHM according to the number of Lync servers in the network. For example, purchase a 50-node license for 50 Lync servers. You cannot import more Lync servers than the node limit of a license. Prerequisites for UCHM operation For UCHM to operate correctly, deploy a Lync monitoring server on the monitored Lync network and install the Skype for Business SDN Interface. A Lync monitoring server collects service quality information for Lync calls or video conferences. If a Lync monitoring server is not installed, the details of call records in UCHM might not be complete. The Skype for Business SDN Interface is a programming interface provided by Microsoft to access Lync diagnostic data (for example, Lync call quality information). IMC UCHM 7.3 (E0501) supports only Skype for Business SDN Interface Download Skype for Business SDN Interface and the installation guide at For IMC servers to receive messages from the Skype for Business SDN Interface, you must configure one or more IP addresses after installing the Skype for Business SDN Interface. Skype for Business SDN Interface allows you to configure IP addresses by using the command line interface of the SDN Manager. The following is an example: SDNManager.exe p s imcnms submituri= In this example, imcnms is the subscriber name and :8080 is the IP address of the IMC server. To configure multiple IP addresses, you must define multiple subscribers. For more information, see the document Skype for Business SDN Interface provided when you download the interface.
