The list the current supported and unsupported Telemetry platform features are provided in the following topics:
The CVP Telemetry Supported Features table lists the supported features. Review the supported features to ensure you are aware of the features available to you to monitor devices using Telemetry data.
|Real-time monitoring of devices||The Telemetry platform provides interfaces for viewing real-time updates about changes in device state as well as events. You can also view trends in device-state metrics and queries of historical device-state data.|
|Instant state change updates||Changes in the state of a device are instantly streamed to CVP.|
|Full state change data||
All changes in device-state are captured and streamed to CVP for viewing. Types of device-state include:
|Analytics engine||The Telemetry platform provides a robust analytics engine that aggregates the streamed device-state data across devices, monitors device state, and generates events to indicate issues. It also normalizes data so it is easier for other applications to use.|
Device-state and system environment event types are streamed to CVP:
|High performance database||
The Telemetry platform utilizes a high performance Hbase database to store device-state data, including events. Data is stored in compressed format without a loss of resolution.
|Disk space protection||
To prevent telemetry data from consuming too much disk space in the CVP cluster, the Telemetry platform automatically blocks the ingest port for the entire cluster if disk usage exceeds 85% on any node of the cluster.
Once the ingest port is blocked, it remains blocked until disk usage drops below 80% on all nodes in the cluster.
To ensure that the most relevant data is given priority, the Telemetry platform provides automated data management, including:
Periodic clean-up jobs are executed weekly (Saturday at 11:00 P.M.). Old device-state data is purged.
Several commands are provided for:
The CVP Telemetry Unsupported Features table lists the unsupported features. Review the limitations to ensure you do not inadvertently attempt to configure or use unsupported Telemetry features.
|Streamed device-state data||Flexroute is not supported.|
