Is there a way to tell how close an earthworm message ring is to becoming saturated?

[Stephen Brewer]

Is there a way to tell how close an earthworm message ring is to being saturated? I suppose there may not be a general way, since there is no "time to live" parameter. Messages just stay on a ring indefinitely, until they are pushed off by newer messages? The interest here is to make message rings no larger than necessary. I am thinking that there isn't anything available to measure this sort of thing. I know that for tracebuf? messages you have wftimefilter, gaplist, and ewagent.

thanks, steve.

Hi Steve,

For sniffwave there is now a feature where you can have it run for some fixed number of seconds and collect statistics on the ring.

sniffwave WAVE_RING STA HHZ NC 00 5

where 5 is the number of seconds to run and collect statistics. From that you can do multiple runs and see how much data flow through a ring in some time and get some handle on waveform flow.

There is no equivalent for sniffring, but probably wouldn't be too hard to add that feature in. Perhaps we will do this for our EW class in June.

Cheers,

Paul
