Number of port users logged in - 2.1-RELEASE

[skron]

Thanks, this still works (2.3.4)

I implemented it differently, but using your script. I uploaded the script in the captive portal and my cacti-install gets the value via https from https://pfsensehost:8003/captiveportal-cpcount.php and graphs the output… works great! Finally CP count monitored.

An OID for SNMP would be great though.

Hello, here is my version of the script :

<?php
	require_once("/etc/inc/util.inc");
	require_once("/etc/inc/functions.inc");
	require_once("/etc/inc/captiveportal.inc");

	/* read in captive portal db */
	/* determine number of logged in users */
	$count_cpusers = 0;
	/* Is portal activated ? */
	if (is_array($config['captiveportal'])) {
		//only one zone
		if(isset($_GET["cpzone"])){
			$cpzone=$_GET["cpzone"];
			$count_cpusers = count(captiveportal_read_db());
		}
		else {

			/* For every zone, do */
			foreach ($config['captiveportal'] as $cpkey => $cp) {
				/* Sanity check */
				if (is_array($config['captiveportal'][$cpkey])) 
					/* Is zone enabled ? */
					if (array_key_exists('enable', $config['captiveportal'][$cpkey])) {
						$cpzone = $cpkey;
						/* Zone selected -> count users and add */
						$count_cpusers += count(captiveportal_read_db());
					}
			}
		}
	}

	echo $count_cpusers;
?>

Here is how i check it with centreon :

#!/bin/bash
url=$1
libelle=$2
warningvalue=$3
criticalvalue=$4

if [ $# -eq '4' ]	
	then

        #get the value
	value=$(curl -sk $url)

        # UNKNOWN
         if [ -z "$value" ]
         then
                echo "UNKNOWN - unable to establish the value returned"
                exit 3

        # OK
         elif [ $value -lt $warningvalue ]
	 then
		echo "OK  - $value $libelle| value=$value"
		exit 0

        # WARNING
         elif [ $value -gt $warningvalue ] && [ $value -lt $criticalvalue ]
	 then
		echo "WARNING - $value $libelle| value=$value"
		exit 1

	#CRITICAL
	 else
	 	echo "CRITICAL - $value $libelle| value=$value"
		exit 2
         fi


else
	echo "Usage $0 url \"description of the value\" warningvalue criticalvalue"
	exit 1

fi

this script is used like this :

check_http_value https://10.11.0.1:8005/captiveportal-count-online-users.php?cpzone=captive_portal_r "users connected" 150 200
OK  - 127 users connected| value=127

maybe it is possible to improve this with using the $HOSTADRESS$...

and here is the final result in centreon :
