[smokeping-users] smokeping styled graphs from command line

[Rodney Machado]

HI Tom,
 
I will give a try, it seems that indeed I can extract the right sintax from that error output.
 
Now the answer to the why question. The thing here is that I want to have smokeping type of graphs available within Cacti (http://www.cacti.net). There have been a couple implementation of SmokepingLike graphs for Cacti, but, for me after reading the code and how the graph magic have been done, the truth is that they are not close enough to the original smokeping so I decided to write a graph template for Cacti that can produce something more similar to smokeping.
 
Rgds,
--RM

Hello Rodney;

I've found (by accident) that you can trick smokeping.cgi into dumping
the graph invocation by passing it an incorrect slave parameter, e.g. on
the demo site, hitting this URL:

http://oss.oetiker.ch/smokeping-demo/?target=Customers.OP.johan~otoro

...will throw an error that includes the all of the RRDs::graph commands
that would have been used to generate the images.  I'm not sure offhand
how compatible the syntax is with rrdgraph directly, but it should give
you a general idea of what's happening under the hood.

I'm curious as to why you want to create the graphs manually; are you
aware that you can generate the graphs on the command line by invoking
smokeping in static mode (using --static, naturally)?
