[rrd-users] Re: Front-end suggestions ? - comments

[James Schnack]

Thanks a lot to Don and Mark for their insight. I will keep in mind your 
opinions & suggestions.

I have some questions regarding Mark's comments:

>(heh)
I have. And I have.  ;-)

>-  I found that it was best for me to write my own frontend to rrdtool.
What was the best way you found to do that ? Did you use rrdcgi ? Or maybe 
the RRDs module and "regular" perl cgi scripts ? (This sounds to me as more 
efficient and orderly way to do it.)

>- Each server/metric combination is its own rrd file
Ok. I like that.

>- alarms - this is likely a function of the data collector, not rrdtool,
Mmmm, yes, you're right. So I guess I could include threshold checking in my 
data-collecting perl scripts, which will be using 'snmpget' and 'rrdtool 
update' to do the job. Does this make sense ?

Yeah, but I was planning to leave MRTG out of the picture.

Cool!

>hope this helps
Sure did!


Thanks a lot for your help!
