A computing resource monitoring service receives a request to retrieve measurement data for a metric. The computing resource monitoring service determines, based at least in part on information included in the request, one or more in-memory datastores where the measurement data is stored. If the information indicates that the computing resource monitoring service is to provide an authoritative subset of the measurement data, the computing resource monitoring service limits the data provided in response to the request to the authoritative subset of the measurement data. Otherwise, if the information does not specify this indication, the computing resource monitoring service will provide the measurement data that is available. |

1. A computer-implemented method, comprising:
under control of one or more computer systems of a computing resource monitoring service provided by a computing resource service provider,
receiving, from a customer computer system of a customer of the computing resource service provider, a first application programming interface call to retrieve a first set of measurements for a metric, the first application programming interface call including a fully qualified metric identifier, and specifying a time range for the first set of measurements and a parameter indicating that the first set of measurements are to be authoritative;determining, based at least in part on the fully qualified metric identifier and the specified time range for the first set of measurements, one or more datastores where the first set of measurements are stored;obtaining the first set of measurements from the determined one or more datastores where the first set of measurements are stored;determining if the first set of measurements obtained from the determined one or more datastores are authoritative;as a result of the first set of measurements being authoritative, providing the first set of measurements in response to the first application programming interface call;receiving, from the customer computer system, a second application programming interface call to retrieve a second set of measurements for the metric, the second application programming interface call including the fully qualified metric identifier, and specifying a time range for the second set of measurements and a parameter indicating that the second set of measurements are to be obtained regardless of whether a time period for storage of measurements for the metric has elapsed;determining, based at least in part on the fully qualified metric identifier and the specified time range for the second set of measurements, one or more datastores where the second set of measurements are stored;obtaining the second set of measurements from the determined one or more datastores where the second set of measurements are stored; andproviding the second set of measurements in response to the second application programming interface call. |
