Hi Balbir and Shailabh,
I propose we add the capability to turn ON/OFF the multicase of
taskstats accounting data at do_exit().
This would allow 'chkconfig taskstats' like of control similar
to 'chkconfig acct' for BSD accounting. Sometimes sysadmins would
wish to turn off sending accounting data to the multicast socket.
We have seen many situations that our CSA customers need to turn
off CSA for a period of time.
What happens to other clients listening to the data ? This sort of
configuration option would
again be along the lines of a systemwide change prompted by needs of one
subsystem but affecting
all others - something Andrew had recommended against doing while we
were discussing the per-tgid
turnoff.
The existing way to solve this is for the listeners to close the socket
and reopen again later when they
are interested. If there are no listeners at all, data won't be sent by
the kernel anyway. Won't that work
for you ?

I think this feature is very important to this new interface.
Thanks,
