Abstract: A baseboard management controller (BMC) installed in a server or other hardware device may perform operations to monitor and safeguard metering data for one or more hardware component of a server that includes the BMC. The BMC may periodically transmit a metering data message over a network to an event destination, where the metering data message includes the utilization levels of the hardware component during a period of operation. In response to detecting a loss of communication with the event destination, the BMC may perform lossy compression of the monitored utilization levels for the hardware component, wherein the lossy compression produces a utilization value that is representative of the monitored utilization levels, but uses less data storage capacity. The utilization value may be transmitted to the event destination instead of the monitored utilization levels in response to determining that communication with the event destination has been reestablished.
