Guidelines for Collecting Metrics from Provider Connectivity Assurance Sensor Control

This article provides further engineering guidelines related to metrics collection from the Provider Connectivity Assurance Sensor Control controller.

Assurance Sensor Control Data Retention

Under normal operating conditions, Assurance Sensor Control collects performance metrics and transmits them to Legacy orchestrator for reporting purposes.

In the event of a loss of communications with Legacy orchestrator, the Assurance Sensor Control will persist unsent data to disk. On recovery of the communications channel, persisted data will be transmitted to Legacy orchestrator and normal operations will resume.

The amount of data that can be persisted depends on the session type as well as the disk configuration of the Assurance Sensor Control. The following sections detail the retention times for the various session types of the Assurance Sensor Control.

Maximum Metrics Objects of Assurance Sensor Control

The number of data points that can be retained is driven by the object type generating the metrics. The Assurance Sensor Control has two storage models, a per object model and a shared pool model. The per object model supports a fixed number for data points that can be stored for each instance.

The shared pool model provides data storage that is shared amongst all objects that belong to the pool. The type of storage used by a particular object type is not configurable. The table below describes, for each object type, which storage model is used and the storage capacity available.
