Reason

Client action

INVALID_REQUEST  (42)

Log an error and stop pushing metrics. This is viewed as a problem in the client implementation of metrics serialization that is not likely to be resolved by retrying.

INVALID_RECORD  (87)

Broker failed to decode or validate the client’s encoded metrics.

Log an error and stop pushing metrics. This is viewed as a problem in the client implementation of metrics serialization that is not likely to be resolved by retrying.

TELEMETRY_TOO_LARGE  (NEW)

Client sent a PushTelemetryRequest larger than the maximum size the broker will accept.

Reduce the size of the metrics payload so its size does not exceed GetTelemetrySubscriptionResponseGetTelemetrySubscriptionsResponse.TelemetryMaxBytes.

UNSUPPORTED_COMPRESSION_TYPE  (76)

Client’s compression type is not supported by the broker.

Immediately send a GetTelemetrySubscriptionRequest GetTelemetrySubscriptionsRequest to get an up-to-date list of the broker's supported compression types (and any subscription changes).
