[Click] How to log Queue size and drops

[Simon Schuetz]

Hi,
I'm using the configuration
FromDevice(eth0) -> Queue(xxxx) -> DelayUnqueue(0.05) -> ToHost(eth0)

I want to adjust the Queue size, but how can I find out about the
highest usage of the Queue? How can I log the high_watermark?

I there any possibility to get some information whether the queue
dropped some packets for any reason (overfull,....)

Thanks
Simon
