User quality of experience in a real time communication system is determined by analyzing endpoint performance metric reports correlated with performance factors of each endpoint in an endpoint profile for a more complete view of an audio/video quality of experience. Reports may include endpoint profile reports, which may be sent once at the beginning and then again only if an endpoint attribute changes; session reports, which include measured metric information and are sent at the conclusion of each session; and session interval reports, which also include metric information, but are sent during the session based on a period or a predefined threshold.

Endpoint report aggregation in unified communication systems

Performance of endpoints, client devices and servers within a communication system, is monitored by collecting call quality data from each endpoint. The collected metric data is retrieved periodically from a database, categorized based on endpoint location and metric type, and compared to predefined thresholds for different endpoint types, metric categories, and call configurations. If an alert condition is met indicating a problem with quality of experience in the system, an alert is issued to an administrator.

Techniques for measuring an operating system's boot duration are provided. The techniques include adding a startup application to an operating system's list of startup applications, determining when the startup application was invoked, and calculating a boot duration for the operating system. The techniques further include loading a log file containing indications of system activity occurring during a boot process, identifying a time interval having a peak system activity, identifying another time interval having a fraction of the peak system activity, and indicating that the boot process completes at a time during the second time interval.
