Overview of Network Monitoring, Reporting, and Diagnostics
Cisco Prime Collaboration is a comprehensive video and voice service assurance and management system with a set of monitoring, reporting, and diagnostic capabilities that help ensure end users receive a consistent, high-quality video and voice collaboration experience.
Prime Collaboration offers the following benefits:
•Provides provisioning, monitoring, reporting, and diagnostic capabilities for Unified Communications Systems.
•Supports timely, end-to-end visibility and isolates voice and video-related issues for sessions (calls), endpoints, and the network.
•Reduces time to troubleshoot and recover from service-affecting problems.
•Provides detailed analysis of the media (voice and video) path with critical fault and performance statistics that enable you to isolate network devices that cause service degradation.
•Delivers reports that enable you to track usage and problem history.
Prime Collaboration Dashboards
The Prime Collaboration Dashboards enable you to monitor your collaboration network end-to-end.
The following dashboards are available from the Prime Collaboration home page:
Information about sessions and alarms.
Information about endpoints and how they are utilized.
Information about conferencing devices, management devices, call and session devices, and video ports.
Information about pending orders, device synchronization status, and deployment status. This dashboard is available only when Assurance and Provisioning servers are converged.
For more information about dashboards, see the Prime Collaboration Dashboards chapter.
Prime Collaboration provides a detailed analysis of the end-to-end media path, including specifics about endpoints, service infrastructure, and network-related issues.
Prime Collaboration enables you to monitor all voice and video collaboration sessions. These sessions can be ad hoc, static, or scheduled with one of the following statuses:
Prime Collaboration periodically imports information from:
•The management applications and conferencing devices on the scheduled sessions.
•The call and session control devices, such as Cisco Unified Communications Manager (CM) and Cisco TelePresence Video Communication Server (VCS), on the registration and call status of the endpoints.
Note You can monitor the sessions only when the endpoints are registered to Cisco Unified CM or Cisco VCS, and managed in Prime Collaboration.
Prime Collaboration manages multiple call and session control clusters. It monitors sessions within a cluster and among clusters (intracluster and intercluster sessions). You must ensure that the cluster IDs and cluster names are unique.
You can perform the following session management tasks:
•Check the session topology and the participant status. The session topology contains details on collaboration endpoints and call and session control devices.
•Monitor the quality of service for the endpoints that are part of a session that is in progress.
•Import the scheduled sessions from the application manager and multipoint switches.
•Collect the session statistics (video and audio) for a session that is in-progress and for past sessions.
•Collect the endpoint details, such as peripheral, session, and inventory.
•Identify the alarms that are associated with the session.
•Troubleshoot a session that is in-progress.
•Add a session to the watch list. Prime Collaboration performs automatic troubleshooting when a session is added to the watch list.
See the Monitoring Sessions chapter to learn how to keep the session details updated, monitor a session fault, and troubleshoot a session.
Prime Collaboration enables you to monitor the status of all managed endpoints. It displays the following details for managed endpoints:
•Alarms (Critical, Major, Minor)
•Status (In use, Not in Use)
•System details (software version, CPU utilization, physical memory utilization, and so on)
•Peripheral details (IP phones, camera, microphone, and so on)
For information about the endpoints data that is collected by the Prime Collaboration server, see the Monitoring Video Endpoints chapter.
You can use the Prime Collaboration reports to identify problem areas, locate poorly utilized systems, and determine ideal locations and required endpoint types for future deployment.
You can generate the following report types:
See the Prime Collaboration Reports chapter to learn how to generate reports.
Prime Collaboration enables you to troubleshoot sessions that are in progress. Automatic troubleshooting is triggered when a major alarm is raised (due to packet loss, jitter, and latency), or when a session is added to the watch list.
In point-to-point and multisite sessions, troubleshooting is performed between the endpoints. In a multipoint session, troubleshooting is performed between the active endpoints and the conferencing devices.
Prime Collaboration discovers the complete path trace between the endpoints during the troubleshooting workflow. It also provides the capability to facilitate the readiness assessment of a network to deploy Cisco Video or TelePresence systems (using VSAA).
The troubleshooting data for a session is retained in the Prime Collaboration database, and you can export this data.
Session Troubleshooting with Cisco Medianet
Prime Collaboration uses Cisco Medianet to provide enhanced path computation, statistics collection, and synthetic traffic generation. When network devices are Mediatrace-enabled, Prime Collaboration provides:
•Detailed flow-related information along with the video path.
•Snapshot views of all traffic at network nodes using Cisco Performance Monitor.
•Ability to initiate synthetic video traffic from network devices, using IP SLA video operations to assess video performance on a network.
While performing the troubleshooting for a session, you can cross-launch Cisco Prime Network Analysis Module (NAM) and Cisco Prime LAN Management Solution (LMS) applications to further analyze the issues on the network devices that are connected between the endpoints.
See the Diagnostics for Video Endpoints chapter to learn how to troubleshoot sessions and networks.
Troubleshooting for Phones
You can collect the troubleshooting data for phones using the UC Topology and Diagnostic Views.
The UC Topology and Diagnostic Views provide the following information:
•Registration status of IP telephony and voice gateway devices.
•SRST status of SRST-enabled devices.
•Logical relationship between all voice devices.
•High-level summary of the faults on all Unified CM clusters.
•Number of calls attempted and completed over the last 24 hours in each Unified CM cluster.
•Summary of the batch, synthetic, and phone tests.
•Summary of events across all the devices in a cluster.
•High-level cluster information
