Adding the SHIFT parameter

[thehemi]

See this thread...

Graph Data X over Two Time Ranges
http://forums.cacti.net/viewtopic.php?t=9101

To sum the thead up...

DEF:a="cpu.rrd":cpu:AVERAGE
DEF:b="cpu.rrd":cpu:AVERAGE:end=now-XXX:start=end-XXX
SHIFTXXX

now/end are going to be already known variables.
If there was a way to include XXX and allow the
SHIFT parameter to be an available option when
adding Graph Template Item, Cacti would support
graphing current vs old data on the same graph...

Not sure how easy/hard this is... but it would rock!

Do we, the lowly users, get any clues on which features
you might be considering? I'd be curious to know if my
request is going to get any thought, if it was just tossed,
or if there's any additional information I can provide that
might help in the decision/developmental making process.

If RDDTool supports it, I would say it's possible, but I don't know if it does.

The RRDtool absolutely supports this SHIFT function.
That's why I was suggesting the feature be added to
Cacti. I'm able to create these graphs by hand with
RRDtool, but we'd love to be able to do it with Cacti.

Hello,

searching in this forum for the feature exactly described above, I would like to know if one can use CACTI now in this way. I would like CACTI to generate rrdtool graph code like

Code: Select all

DEF:a="somefile.rrd":traffic_in:AVERAGE \
DEF:b="somefile.rrd":traffic_in:AVERAGE[b]:end=now-1d:start=end-1d \
SHIFT:b:86400 \[/b]
LINE1:a#FF0000FF:"Inbound"  \
LINE1:b#00FF00FF:"Inbound[b] - 1 Day[/b]"  \

Is this feature planned or implemented by now?

Thanks in advance,

Daniel

It is planned. We do plan to support all available rrdtool parameters. Currently there's not an exact timeframe when we will support which parameter.
The most complicated part is the verification of valid rrdtool commands because it depends strongly on the rrdtool version used.
We were already thinking about allowing for some "free format text field" to allow for a custom string passed to rrdtool. This would be on your own risk. But we do not love this approach because it will increase "support requests"

Thank you for your response

[gandalf]

It's in! See upcoming 088 version
R.

[nazagoth]

So, there any plans to launch the 088?

I'm searching shift options to graph with shadow

any ideas?

[gandalf]

We don't have an exact schedule yet. But please tell me how you want to implement that shadow thingy using SHIFT
R.

[nazagoth]

like this:

but I need this on cacti :/

[gandalf]

I apologize, but for that graph the new support is in fact required.
You may want to download current code and verify, that it does what you need. But that code is by far not production-ready
R.

[nazagoth]

hmm, thanks for the answers by the way

can you say if the new version will be launched this semester at least? or another forecast like this?

[gandalf]

Unfortunately, my latest assumptions all failed. So I refrain from getting more frustration like that.

[nazagoth]

hahaha allright (: thanks again
