Bonjour,
J’ai installé Nagios sur Debian 6 et ainsi que cacti.
J’ai voulu testé le plugin cactiplug pour améliorer les performances de mon logiciel superviseur.
J’ai donc suivit un tutoriel très complet sur le net pour savoir comment lier cacti et nagios.
Malheureusement, j’ai un petit soucis.
Quand je vais dans Nagios et je clique sur le petit icône représenté par une courbe à côté de l’host, ça me marque que
"Address IP incorrect or hostname incorrect" voici ma configuration :
cacti version 8.7.g
nagios version 3.4.1
cactiplug.php
[quote]$cactiurl=“http://localhost/cacti”;
$database_default = “cacti”;
$database_hostname = “localhost”;
$database_username = “cactiadmin”;
$database_password = “cactipassword”;
##########
function checkip($address) {
if(is_string($address)) {
# Is it IP…?
$ip = ip2long($address);
if( $ip != -1 && $ip !== FALSE) {
return $ip;
}
#…or hostname?
elseif(gethostbyname($address) != $address) {
return $address;
}
}
return false;
}
Main Code
###########
Get the IP ip oh the host (GET method)
if (isset($_GET[“ip”]) && checkip($_GET[“ip”])) {
$ip = $_GET[“ip”];
$address = gethostbyname($ip); # (We already sanitize it in “checkip” function)
} else {
die(“Incorrect IP or hostname”);
}
Connect to the Cacti DB
$link = mysql_connect($database_hostname, $database_username, $database_password)
or die(“Error while connecting to the DB server”);
mysql_select_db($database_default)
or die(“Could not select database”);
Build and execute the SQL request
$query = “SELECT graph_local.id AS local_graph_id, host.id AS host_id, host.hostname AS hostname “
.“FROM (graph_local, host) “
.“WHERE graph_local.host_id=host.id AND host.hostname LIKE '”.$ip.”’ OR host.hostname LIKE '”.$address.”’”;
$result = mysql_query($query)
or die(“Query failed”);
Get the result (the last one)
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$action_url = $cactiurl."/graph_view.php?action=preview&host_id=".$row[“host_id”]."";
}
header("Location: ".$action_url);
}
else {
die(“Host not found, sorry…”);
}
Close the DB session
mysql_free_result($result);
mysql_close($link);
?> [/quote]

Ma configuration dans cacti “global.php”

/* Default database settings*/
$database_type = “mysql”;
$database_default = “cacti”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;

$database_ssl = false;[/quote]
J’espère que vous pourrez m’aider
