type UDPListener added in v1.18.0

type UDPListener struct {
	ServiceAddress string

	// UDPBufferSize should only be set if you want/need the telegraf UDP socket to
	// differ from the system setting. In cases where you set the rmem_default to a lower
	// value at the host level, but need a larger buffer for UDP bursty traffic, this
	// setting enables you to configure that value ONLY for telegraf UDP sockets on this listener
	// Set this to 0 (or comment out) to take system default
	// NOTE: You should ensure that your rmem_max is >= to this setting to work properly!
	// (e.g. sysctl -w net.core.rmem_max=N)
	UDPBufferSize          int `toml:"udp_buffer_size"`
	AllowedPendingMessages int

	// UDPPacketSize is deprecated, it's only here for legacy support
	// we now always create 1 max size buffer and then copy only what we need
	// into the in channel
	// see https://github.com/influxdata/telegraf/pull/992
	UDPPacketSize int `toml:"udp_packet_size"`


	PacketsRecv selfstat.Stat
	BytesRecv   selfstat.Stat

	Log telegraf.Logger
	// contains filtered or unexported fields
