org.opennms.netmgt.telemetry.protocols.nxos.adapter.NxosGpbParserUtil

public class NxosGpbParserUtil
extends Object

Utility to parse any key/value metric from gpb messages. Since there is no easy way to get key/value metrics from repeated data_gpbkv, this utility provides some methods to get values for those metrics without bothering about structure they may follow.
