Chapter 10 DeviceListX Report

Benefits

•Device Pool

•IP Address

•Real-Time Information

The completed list of data gets formatted into a simple XML object and gets returned in the HTTP Response to the developer.

Benefits

DeviceListX provides access to critical real-time data that was previously unavailable to third-party developers. In particular, the ability to list currently registered devices along with their IP address allows developers to easily build push, broadcast, and CTI-type applications.

Restrictions

Only users with administrative privileges to the Cisco Unified Communications Manager

Administration can access the report.

Note To minimize processing overhead on the Cisco Unified Communications Manager server, access to the DeviceListX report gets rate-limited to once per minute. Any attempt to pull the report more frequently will fail. In practice, the developer application should pull and cache the DeviceListX report, refreshing only as often as required, typically every few hours or daily.

Integration Considerations and Interoperability

The interface allows HTTP 1.1 or HTTP 1.0 GET requests for the report. The report returns data that is encapsulated by using XML version 1.0.

Performance and Scalability

You can run this report on the largest supported Cisco Unified Communications Manager cluster size for the targeted release without impacting core features, such as delaying dial tone. On multiserver Cisco Unified Communications Manager clusters, the report can access only from the publisher server. In large clusters where the publisher is not a Cisco Unified Communications Manager server, no possibility exists of impacting the system performance as perceived by a user.

This report is not intended for use during real time, so this interface should provide a mechanism for developers to poll for the data on a daily or hourly basis. Give consideration to the frequency of polling and the time of day to prevent unnecessary burden on the system during peak usage times.
