The problem continues ...
I have checked a
while 1
do
telnet ganglia port
done
and sometimes the size of telnet output is 0. In this moment, the debug
mode of gmetad showed "Clearing", and seconds later the output size was
growing while the gmetad debug mode showed "Writing or Updating".
Do you know when the "Clear" event is executed ??
Regards
Miguel.
