Heres version 2

A few improvements with the output
added some of the Holt-Winters stuff (possibly more to come if theres interest)
added a rough filesize estimator (I don't know what the overhead is for a rrd but this is within a few Kb)

This version isn't as clean and the javascript is probably the most inefficient way of doing things, but it works. Feel free to make improvements or post here with bugs.

Trying to create RRD archive for 1 minute patterns, the calculator generate such command

Code: Select all

rrdtool create newdata.rrd --step 60 \
DS:data:GAUGE:120:U:U \
RRA:AVERAGE:0.5:0.5:86400 \
RRA:AVERAGE:0.5:30:17520 \

but it give me "ERROR: Invalid step 0.5: value has trailing garbage" with RRDtool 1.8.0
This could be fixed by change second '0.5' value in first archive definition from

Code: Select all

0.5

to

Code: Select all

1

What could be wrong?

That appears to be a bug. Not sure how the step was set to 0.5. The minimum step is 1.

Your Data Source Profile > Edit page should look something like below. Notice the Steps leads off with 1.

I dont use Cacti, but scripting rrdtool directly. Found this thread is in the source of calculator, that is why I am asking here.

That is why I am writing it here, this only known contact to author

As you can probably tell by the dates I haven't touched this in a very long time. @TheWitness is correct, it's a bug.
