[smokeping-users] RRD Command for generating Smokeping graphs via CLI

Fri Jul 13 08:47:31 CEST 2012

Hi Don,
Many thanks for your response and no worries re: being blunt. 

Essentially, you are right - only that the only custom item I require is the title. In other words, the legend and everything else on the graph should remain the same as what's seen in smokeping. Moreover though, I also need to 'automate' this graph generation via CLI/ a perl script.

So to do the above, I thought the best way would be to use the rrdtool directly from CLI; something like:

/usr/bin/rrdtool graph - --imgformat=PNG --start=-31536000 --end=-300 --title="customer abc instead of Navigator Graph"................

What I was after was simply the list of all the parameters I might need to pass to rrdtool so as to generate a graph that looks exactly like the ones generated by smokeping (only with a different title). 

I'll go through the links you provided me with as the second one seems promising. 

The alternative to all the above would be to run something like this from a linux CLI:

[root at foo /]# wget " http://oss.oetiker.ch/smokeping-demo/?displaymode=a;start=2007-08-15%2015:31;end=now;target=Customers.ITIS.otoro"

The above is also fine for me and would be much simpler. The only problem with it is that I don't know if/how I could modify the graph title of the png file generated? Maybe there's some other url parameter I can pass? E.g. ?displaymode=a;start=2007-08-15%2015:31;end=now;target=Customers.ITIS.otoro;title=customer.abc (<-note added parameter).

Thanks for all your help.

Joe

Joe,

My reading of this thread is that you have asked the wrong question. 
Or, at least you have not explained what you requirement is very clearly 
and I wonder if you have also asked on the wrong list.[1]

As a result you are not getting the help you're looking for.

My understanding of your requirement:

* Produce a graph 'image' from an RRDTool database with custom titles 
and legend information on it.

------------

The fact that the "SmokePing" application put the data in to the RRDTool 
database is only coincidental.

So, http://oss.oetiker.ch/rrdtool/

http://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html

http://oss.oetiker.ch/rrdtool/doc/rrdgraph_examples.en.html

Is this more what you're after?

D

[1] Please excuse my blunt, and perhaps rude, break down of the problem 
here.  I do not mean to offend, I just felts you weren't getting 
anywhere and wondered if it's a language problem that's causing 
confusion.  So the best way I could think of to try and help was by 
being a bit more direct and black and white.
