thanx Howie,

You are right, DS names are in and out and not traffic_in,traffic_out...
I 'll try to modify these settings according to your advice and i tell you about the result...

Is 0.9 version available?

i 've change the following code (Weathermap.class.php file) from traffic_in and traffic_out to in and out (my DS names):

function ReadFromRRD($target, $in_ds = "traffic_in", $out_ds = "traffic_out")
{
$inbw=-1;
$outbw=-1;

// we store the original TARGET string, and line number, along with the breakdown, to make nicer error messages later
$newtarget=array
(
$target,
'traffic_in',
'traffic_out',
$linecount,
$target
);

Here is the output of the latest log entries:

The syntax you told me which is TARGET path_to_rrd.rrd:DSNAME1:DSNAME2 is correct

I have installed Version 0.82 as standalone and not as cacti plugin to control error messages better...and it worked

Let's say i'm interested in representing only the percentage of link utilisation...
RRD holds values from snmpget that is cells...is there a place in code where i can modify and transform the MAX Bandwidth of the link which is given in bytes and transform it automatically to cells (by diving it by 53)and get the correct percent? (1 cell= 53 bytes)

as a standalone it works for sure..
In cacti the most likely scenario is that when i used the editor i forgot to add the DSNAME1:DSNAME2 after rrd so it's not application's fault...

I 'm polling an ATM switch so all the results are in cells.In particular i want to graph the ATM trunks between ATM switches..
So i have their maximum bandwidth in cells (353207 - STM-1) and i also have the cells that passed through the interface.
Do you have an idea on how i could take this number as a percentage?
It's easy to take it in Cacti by applying a CDEF function..
Do you think that i could use the max number of cells in the field (in editor) that expects bits?

Just in case anyone runs into the same problem I did (a few posts back) where weathermap works from the commandline, but not through cron:

In my case it was a bit complicated. I have two different versions of PHP installed on the system to deal with some incompatiblities with some applications. In any case, poller.php was set to use one, and weathermap was set use the other. Why that caused an issue, I have no idea. After setting them both the same -- no problems.

Hello Howie,

everything works just fine!
The tricky part was to multiply by 8 (thank God you remembered it correctly). Considering bits as cells i get exact the same values as from Cacti with the CDEF function.

Thanx for you help!

hi i'm using cacti 0.8.6h with plugin patch installed. i'm trying to make weathermap editor run but all i get is this (see below) it happens when i try to click on the first page the "simple.conf" file. PHP Weathermap version 0.82 is the one i got.

Fatal error: Call to undefined function imagecreatetruecolor() in c:\Inetpub\wwwroot\cacti\plugins\weathermap\Weathermap.class.php on line 2962

what could be causing it? thanks for the help.
