Finding out Netty Client's throughput

[Khayam Gondal]

I have above setup. A 3rd party client is sending traffic over 10G link to my netty server and I have to forward it over a 1G link using Netty client. As I can't write very fast, I also need to adjust my read speed. Is there anyway using Netty's API to find out how fast my channel is capable of sending so I can adjust my read server bandwidth.

Hey,

Usually you would use channelWritabilityChanged events to do this.

Set your WriteBufferWaterMark when bootstrap your Channel and then add a ChannelInboundHandler that implements channelWritabilityChanged(…). Depending on if Channel.isWritable() you can either stop or start reading again by either trigger Channel.config().setAutoRead(false|true). Or if you want to be even more flexible you can configure the Channel to not use auto-read at all and manage the calls to Channel.read() by yourself.

Hope this helps,

Norman
