Trustworthiness index computation in a network assurance system based on data source health monitoring

An apparatus, comprising:

• one or more network interfaces to communicate with a network;
• a processor coupled to the network interfaces and configured to execute one or more processes;
• and
• a memory configured to store a process executable by the processor, the process when executed configured to:
• receive health status data indicative of a health status of a data source in a network that provides collected telemetry data from the network for analysis by a machine learning-based network analyzer;
• maintain a performance model for the data source that models the health of the data source;
• compute a trustworthiness index for the telemetry data provided by the data source based on the received health status data and the performance model for the data source;
• and
• adjust, based on the computed trustworthiness index for the telemetry data provided by the data source, one or more parameters used by the machine learning-based network analyzer to analyze the telemetry data provided by the data source.

A tangible, non-transitory, computer-readable medium storing program instructions that cause a device to execute a process comprising:

• receiving, at the device, health status data indicative of a health status of a data source in a network that provides collected telemetry data from the network for analysis by a machine learning-based network analyzer;
• maintaining, by the device, a performance model for the data source that models the health of the data source;
• computing, by the device, a trustworthiness index for the telemetry data provided by the data source based on the received health status data and the performance model for the data source;
• and
• adjusting, by the device and based on the computed trustworthiness index for the telemetry data provided by the data source, one or more parameters used by the machine learning-based network analyzer to analyze the telemetry data provided by the data source.
