[smokeping-users] 25 slaves overwhelming master

[Phillip Moore]

Is there more to making speedy work than just replacing perl with is  
as the interpreter for smokeping.cgi? As far as I could tell it does  
not use the speedy perl module at all. The source I found for speedy  
was from 2005 also.

Also, I haven't setup or hard coded any offset for the slaves to run  
as I didn't see any way to do that. Its unclear if they are running  
at the exact same time now, but I end up with a ton of  
smokeping.cgi's stacked up when I wasn't running it with speedy. I've  
yet to get speddy going 100% yet, so we'll see how that goes if I get  
it working. WHen I say not 100%, speedy and the speedy_backend end up  
getting run, but I got some odd errors (that I've lost now) with the  
various web pages on smokeping.cgi. It also complained about the rrd  
files not being compatible when I started using speedy.

I'll keep poking and see if speedy makes this work better.

Thanks,
