Hi Frederico,
seems I need your help on php/rrd. I tried to add the cpu_wio metrics
to the CPU-Report graphs in graph.php. Below code works fine for
hosts/clusters where cpu_wio.rrd does exist. Unfortunatelly it breaks
for those where cpu_wio.rd does not exist. The graph does not show up.
Is there a way to conditionally just set the cpu_wio values to zero if
cpu_wio.rrd is nonexistent?
Thanks
Martin
