Cacti Data Query not functioning on second associated graph template

Hello Cacti Users,

I have created an XML Data Query which works for my first associated Graph
Template, but not the second.  The information I'm harvesting are mostly
strings in this case, so I'm using |query_NAME| to display them in a

I've confirmed the second graph has the same associations as the first,
though it only refers to one DQ field and not three DQs like the first
Graph Template.  For kicks, I added another field to the first GT and it is
populated fine, so the data is definitely cached/retrieved (plus I see it
via Verbose Query on Device info).

Is there a reason that a DQ cache is not available to a newly associated
Graph Template?

[ Note: I just tested with the SNMP - Interfaces DQ and have modified a
working graph. So this points to something I'm missing or did in the wrong
order? :-( ]

Timeline:  I've had the DQ XML in place for a few days now and recently
added another "input" field to the XML (which I'd like to display on the
second graph).

Vertical line at 24h before current time


I've increased my RRA Archive display from 86400 to 115200 seconds 
(the 'daily' one) so it shows me last 32 hours. 

(e.g. for net traffic displays it can give us perspective of 
how it went 24h before)

I'm looking for a way to insert a line indicating exactly 24h before
the end of graph (or generally : to insert a line at exactly x seconds
before the end of graph).

So that it effectively displays a vertical line showing us exactly the 
last 24 hours.

Problem is, rrdtool expects HH:MM in VRULE value;

How can I make up HH:MM from anything available in the host system?

(cacti Version 0.8.7i)

Kind Regards

Are the forums down?

It appears that forums.cacti.net is down?

Anyone confirm or know?

Fwd: Bug tracker question

Hi All,

I submitted a Private security-related bug to the Cacti bug tracker
earlier last week and haven't had a response on it yet, though I see
responses have been posted for bugs newer than mine.

Just to confirm, are these bugs visible to developers? If so, shall I
leave it there, or would it be better to contact a developer directly?

Cacti data sources and graphs not created (complex)


General / summary:
One of my data queries doesn't work. It's a new one but the same one works on one host and not on another
(actually doesn't work on a couple of others tried).
>From initial (as far as I could) analysis - the data query does not create the graph and data sources
correctly on the effected host(/hosts) and rrd is not created (nor does poller ever retrieves the data).

How do I see a log of a new graph creation (from device -> data query), not the poller events (that aren't,
there are none).

I've took example of two hosts: "Peach" and "Orange", both trying to add the same generated data queries
(from script server) graphs.
It all works well as expected in "Orange", but does not in "Peach"
I've included everything in screenshots (those are temporary internal lab servers so I don't mind) so
you'd get the full picture.
The two differences I can see tell between the two are:

1.       "Peach"'s (not working) MVSnew dataquery is significantly larger (150 items, 75 rows) vs. "Orange"'s
one (8 items, 4 rows).

2.       Peach has a lot of script server data queires, about 65, vs. very little on Orange.

"Active" and "Rate".

We are allready using spine,
but the balancing from hosts to processes/threads seems not to be the best.

The first 20 seconds, the system will be under heavy load,
but later only two spine processes are running and it will already take about 230 seconds to complete one run.

Do you have any suggestions about optimization?
