rss feed as a notification method

[Blake Krone]

Steve what I did for this was parse the status.log file for the
different states of the machines. You could then have a PHP script
that does the parsing put all of the "critical" machines into one
array/xml/rss whatever.

For my use this worked great on my help desk website, I just list the
major servers and have an icon for up, critical, warning, and unknown.

Here's some PHP code to read the status log and put all of the servers
into an array that are accessed via the 'hostname'

***This code is from the NagVis project.****

function GetStatus()
   {
   $l="0";
   $x="0";
   $status_dat = file("/var/nagios/status.log");
   while ($status_dat[$l] != "")
     {
     $type = explode(" ",$status_dat[$l]);
     if ($type[0] == "host")
        {
        $hostname = explode("=",$status_dat[$l+1]);
        $host = trim($hostname[1]);
        $state[$host]['service'] = $host_servicename;
        $current_state = explode("=",$status_dat[$l+9]);
        $host_state = trim($current_state[1]);

        if ($host_state == "0")
        {
           $state[$host]['state'] = "UP";
        }
        else if($host_state == "1")
        {
           $state[$host]['state'] = "Warning";
        }
        else if($host_state == "2")
        {
           $state[$host]['state'] = "Critical";
        }
        else
        {
           $state[$host]['state'] = "Unknown";
        }

        $plugin_output = explode("plugin_output=",$status_dat[$l+12]);
        $state[$host]['plug_out'] = trim($plugin_output[1]);
        $l = $l + 42;
     }
   $l++	;
   }
   return($state);
}

So how I use this on my website is like this:

<?php

$status = GetStatus();

$servers[0]['Host'] = 'CTEX01';
$servers[0]['Desc'] = 'Email';
$servers[1]['Host'] = 'CTDC01';
$servers[1]['Desc'] = 'Logon';
$servers[2]['Host'] = 'CTPROD';
$servers[2]['Desc'] = 'E:\ Drives';
$servers[3]['Host'] = 'KAZBEK';
$servers[3]['Desc'] = 'Internet Proxy';
$servers[4]['Host'] = 'CTXFILES';
$servers[4]['Desc'] = 'Mac File Server';
echo <<<_TABLE
      <p>
        <span class="header">Important Systems</span>
        <font size="-2">
        <table border=0 cellspacing=4 cellspadding=0 width="100%">\n
_TABLE;

foreach($servers  as $key=>$server)
{
  $plug_out = $status[$server['Host']]['plug_out'];
  if($status[$server['Host']]['state'] == 'UP')
  {
    $this_status = "<img src=\"images/recovery.png\" alt=\"$plug_out\"
title=\"$plug_out\">";
  }
  else if($status[$server['Host']]['state'] == 'Warning')
  {
    $this_status = "<img src=\"images/warning.png\" alt=\"$plug_out\"
title=\"$plug_out\">";
  }
  else if($status[$server['Host']]['state'] == 'Critical')
  {
    $this_status = "<img src=\"images/critical.png\" alt=\"$plug_out\"
title=\"$plug_out\">";
  }
  else
  {
    $this_status = "<img src=\"images/unknown.png\" alt=\"$plug_out\"
title=\"$plug_out\">";
  }
 echo <<<_ROW
          <tr>
            <td align="left">$server[Desc] ($server[Host])</td>
            <td align="center">$this_status</td>
          </tr>\n
_ROW;

}

echo <<<_TABLE
        </table>
        </font>
      </p>\n
_TABLE;

?>

It just spits out a table like the following:

Email (CTEX01) ----------  <status icon>
Logon (CTDC01) ---------- <status icon>

That is included on the sidebar of my site.

Hope that helps you into the right direction. I was thinking of making
an RSS feed for it also, just haven't had time. If I do I'll try to
remember to send it your way.
