thank you for help

can i modify the source code of weathermap classes and get the value of link bandwidth. In this case which file i should modify.

The DATAOUTPUTFILE command will do that for you:

Code:

DATAOUTPUTFILE filename

You get a file with the data for all nodes and links, in a format that can be read by the wmdata: datasource plugin.

thank you for your reply.

the value of the bandwidth display in the output file is on bits or bytes?

i need to export the bandwidth of a node to text file because i have an application that check this file and when i have a pic of traffic i get the wethermap image.png displayed in the output directory.

just i modified the source code of the weathermap.class.php and i added this section

Code:

var $my_bb_tt_res = array();



$html .= '<div id="bbttel" style="display:none;">';
$bbtt_max = 0;
foreach($this->links as $link){
   foreach($link->my_bb_tt_res as $key => $value){
      if(substr($value, -1) == 'G'){
      if(floatval($value) > $bbtt_max){
         $bbtt_max = floatval($value);
      }
      }
      //$html .= $value . '|';
   }
}
$html .= $bbtt_max;
file_put_contents('output/bbtt_data.txt',$bbtt_max);
$html .= '</div>

in this version of weathermap i can't find the same files and not the same code. can you please help me to adapt this code to weathermap version 0.98

I don't understand. It already does what you want doesn't it? If you just need one value, grep will get it for you.

It looks to me like Cacti's threshold plugin would be better for what you want, also. If it's an alert when a value goes above a threshold.

thank you for your reply, i use cacti for administration purpose of a router which have multiple links the total of bandwidth is displayed on a link between two nodes. the goal is when i have a pic of traffic i can get the map.png file from the output directory of weathermap. so i developped an application to get this map and i check the max-bandwidth from text file named in my case bbtt_data.txt. i modified the weathermap.class.php to get from cacti the max-bandwidth and store this value into text file. the application work fine but recently i installed this version of weathermap 0.98 and i can't find the same files and code.

this is the older code from the weathermap.class.php 0.92 version

Code:

var $my_bb_tt_res = array();

if (!is_null($q1_x))
      {
         $outbound=array
            (
               $q1_x,
               $q1_y,
               0,
               0,
               $this->outpercent,
               $this->bandwidth_out,
               $q1_angle
            );

         $inbound=array
            (
               $q3_x,
               $q3_y,
               0,
               0,
               $this->inpercent,
               $this->bandwidth_in,
               $q3_angle
            );


foreach (array($inbound, $outbound)as $task)
         {
            $thelabel="";

            if ($this->labelstyle != 'none')
            {
               debug("Bandwidth is ".$task[5]."\n");
               
               if ($this->labelstyle == 'bits') { $thelabel=nice_bandwidth($task[5], $this->owner->kilo); $this->my_bb_tt_res[] = nice_bandwidth($task[5], $this->owner->kilo); }
               elseif ($this->labelstyle == 'unformatted') { $thelabel=$task[5]; $this->my_bb_tt_res[] = $task[5];}
               elseif ($this->labelstyle == 'percent') { $thelabel=format_number($task[4]) . "%"; $this->my_bb_tt_res[] = format_number($task[4]) . "%"; }

               $padding = intval($this->get_hint('bwlabel_padding'));      

               if($this->labelboxstyle == 'angled')
               {
                  $map->DrawLabelRotated($im, $task[0],            $task[1],$task[6],           $thelabel, $this->bwfont, $padding,
                     $this->name,  $this->bwfontcolour, $this->bwboxcolour, $this->bwoutlinecolour,$map);
               }
               else
               {
                  $map->DrawLabel($im, $task[0],            $task[1],           $thelabel, $this->bwfont, $padding,
                     $this->name,  $this->bwfontcolour, $this->bwboxcolour, $this->bwoutlinecolour,$map);
               }
               
            }
         }
      }
   }


// this code is inserted in the function MakeHTML

$html .= '<div id="bbttel" style="display:none;">';
$bbtt_max = 0;
foreach($this->links as $link){
   foreach($link->my_bb_tt_res as $key => $value){
      if(substr($value, -1) == 'G'){
      if(floatval($value) > $bbtt_max){
         $bbtt_max = floatval($value);
      }
      }
      //$html .= $value . '|';
   }
}
$html .= $bbtt_max;
file_put_contents('output/bbtt_data.txt',$bbtt_max);
$html .= '</div>';

how can i adapt this code to weathermap 0.98

It has already changed again in 1.0.0.

But the output from DATAOUTPUTFILE will remain the same.

yes but the output from this file is like that:

Code:

L_T4000-Level3-Ouerdia  6679088203.600000   1523.208000
L_T4000-Level3-Ouerdiaa 8230141220.800000   1526.263200

L_CRS_X-node06852a  7841650889.760000   1176446198.640000

i will make a script shell to get the value from this file every poller period. the value displayed of the bandwidth is on float ? :roll:
