A computing resource monitoring service receives an executable command to redundantly store a metric pertaining to computing resources provided to the customer by a computing resource service provider. The executable command may comprise a hash key and a hash value for the metric. Based on the hash key included in the executable command, the computing resource monitoring service may select one or more data zones, each of the data zones comprising one or more storage nodes for storing metrics. The computing resource monitoring service may be configured to obtain a schedule of storage nodes from the data zones in order to determine the active storage nodes based at least in part on the hash key. Accordingly, the computing resource monitoring service may identify a storage node from the one or more active nodes based at least in part on the hash key and store the metric in the identified node.
