Meaning
Independent verification of data streams from remote sensors or software agents confirms the accuracy of reported operational metrics. Use of telemetry auditing prevents the manipulation of performance figures in cloud based service contracts. This process ensures that the billed usage aligns with the actual consumption of resources.
Data Integrity
Software systems must produce consistent and tamper proof logs of their activity to be used for billing purposes. The data integrity of the system is checked by comparing the logs to independent measurements of the same events. If the two sets of data do not match, it indicates a problem with the collection or reporting mechanism.
Audit Verification
Auditors examine the logs to identify discrepancies between the raw data and the summary reports provided to the client. The audit verification of the telemetry involves replaying a sample of the data stream to see if the resulting metrics match the original output. Discrepancies often trigger a deeper investigation into the collection methods used by the service provider.
In many cases, the contract specifies the frequency of these audits and the penalties for persistent inaccuracies. This verification step provides the evidence needed to settle disputes about service level agreements and usage fees.
Signal Accuracy
Precision of the sensors used to collect the data determines the reliability of the entire reporting chain. The signal accuracy of the telemetry ensures that the small events that trigger a billing cycle are recorded correctly.
