Please post your service and command definitions, attach the plugin as well so that we can debug further.
Thank you

It could be a misconfiguration of the service or command definition. What do those look like? What does the full command look like when you run the script from the command line?

The pluggin is designed to Monitoring springboot actuator health services by cURL and get the Json response; that have the status of services.
Code: Select all
#!/usr/bin/php
<?php
define('STATE_OK', 0);
define('STATE_WARNING', 1);
define('STATE_CRITICAL', 2);
define('STATE_UNKNOWN', 3);
$url_aux = getopt(null, ["url:"]);
if ($url_aux == NULL){
echo "Error no has agregado la URL";
$url = NULL;
exit (STATE_UNKNOWN);
}
$url = $url_aux['url'];
$ch = curl_init($url);
#curl_setopt($ch, CURLOPT_URL, '$url');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Accept: application/json'
));
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
$info = curl_getinfo ($ch);
$code = $info['http_code'];
curl_close($ch);
#$json = json_decode($result, true);
#print_r($json);
echo "\nEstado de Servicios\n";
class JSON {
public static function prettify($json)
{
$array = json_decode($json, true);
$json = json_encode($array, JSON_PRETTY_PRINT);
return $json;
}
}
$jsonString = $result;
echo JSON::prettify($jsonString);
if ( $code !== NULL ) {
switch($code){
case 200:
$text = "Servicios OK";
echo "\n$text\n";
exit(STATE_OK);
case 503:
$text = "Servicio DOWN";
echo "$text\n";
exit(STATE_CRITICAL);

I haven't dug into your full script, but I see this right at the top
the blank line is going to give you a blank line of output right at the beginning of the script which is what Nagios will see as the first link of output and CANNOT be blank
I would recommend changing that to
