[smokeping-users] Smokeping performance tracking

[Jon Greaves]

Hi Tobi,

Just an idea for tracking how smokeping is performing could you get
smokeping to graph the time each probe takes to run. That way you should
get a good indication if you are pushing a single probe to hard.

We have does some basic testing our setup is with 130 groups and around
950 devices with the following results

Setup: 20 ping every 5 mins 1 probe 
Result: the machine struggled to finish 1 full probe cycle under 300
seconds  

Setup 20 pings every 5 mins 1 probe per group (130 probes in total)
Result: waitio time hit 100% and eventually the box crashed

Setup 10 pings every 5 mins 1 probe per group (130 probes in total)
Result: waitio time hit 100% and eventually the box crashed but took
longer than above

Setup 10 pings every 5 mins 10 probes split across the 130 groups
Result: stable but not sure how much overhead we have (see above idea
for tracking)

We are hoping to push the setup up to 2000+ devices monitored once we
get to that I'll post back some additional results.

Current hardware spec
OptiPlex GX520
Intel 1 * P4 HT 3.4gHz
