of virDomainStatsRecords and store the typed parameters as dict.

+        Report statistics of various parameters for a running VM according to @stats
+        field. The statistics are returned as an array of structures for each queried
+        domain. The structure contains an array of typed parameters containing the
+        individual statistics. The typed parameter name for each statistic field
+        consists of a dot-separated string containing name of the requested group
+        followed by a group specific description of the statistic value.
+
+        The statistic groups are enabled using the @stats parameter which is a
+        binary-OR of enum virDomainStatsTypes. The following groups are available
+        (although not necessarily implemented for each hypervisor):
+
+        VIR_DOMAIN_STATS_STATE: Return domain state and reason for entering that
+        state. The typed parameter keys are in this format:
+        "state.state" - state of the VM, returned as int from virDomainState enum
+        "state.reason" - reason for entering given state, returned as int from
+                         virDomain*Reason enum corresponding to given state.
+
+        Using 0 for @stats returns all stats groups supported by the given
+        hypervisor.
+
+        Specifying VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS as @flags makes
+        the function return error in case some of the stat types in @stats were
+        not recognized by the daemon.
+
+        Get statistics about domains provided as a list in @doms. @stats is
+        a bit field selecting requested statistics types."""
