[smokeping-users] Smokeping performance and scalability on high resolution probes

[Louis Soullière]

Hi,
I'm currently trying to configure a smokeping server for diagnostic of our network.
I have manage to make it work but I'm having a couple of issues :
1) How can I reduce the number of ping without getting this error when smokeping generate the graph (In this example, I have set the config to 10 pings) :
"ERROR: No DS called 'ping11' in <rrd file>
2) The other problem is with the performance of tcpping or fping. The probe is working but it take too long to complete. As my step is 5 second, I need the probe to be as quick as possible.Sure, if I can reduce the number of ping, I will gain some time. The concurentprobes variable is on (tried off too). 
I currently have 30 targets running with Fping, wich complete in 5 sec (limit for the 5 sec of my interval).If I switch to TCPPing, it take 42 sec.
My config: 
*** Database ***step     = 3pings    = 5
# consfn mrhb steps total
AVERAGE  0.5   1  38400AVERAGE  0.5  12  4320    MIN  0.5  12  4320    MAX  0.5  12  4320AVERAGE  0.5 144   720    MAX  0.5 144   720    MIN  0.5 144   720
