I have a question in regards monitoring websocket connections on a production box.

We ususally trust whatever is indicated through the 

$ kamctl fifo get statistics

We've seen that this is what the community contributed munin plugins use. However when trying to monitor web socket connections and using this output we've seen completely different results from the output of

$ kamctl fifo get_statistics

websocket:ws_current_connections

Which seem to indicate current websocket connections and the output of

$ kamctl fifo ws.dump

Which seems to indicate current OPEN connections.

Can anybody shed some light as to what are the differences between both if any, and advice which one is the proper one to monitor for possible file handle exhaustion.

TIA
