NRPE and captiveportal check

[jfgatineau]

Hello,
I have write a NRPE check to know how many users are active on the captive portal.
Step 1 :Create the file /usr/local/libexec/nagios/check_cpactiveusers with this code :

#! /bin/sh

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin

PROGNAME=`basename $0`
PROGPATH=`echo $0 | sed -e 's,[\\/][^\\/][^\\/]*$,,'`
REVISION=""

. $PROGPATH/utils.sh

print_usage() {
 echo "Usage: $PROGNAME"
}

print_help() {
 print_revision $PROGNAME $REVISION
 echo ""
 print_usage
 echo ""
 echo "This plugin checks active users using the Active Portal package."
 echo ""
 support
 exit 0
}

WC="/usr/bin/wc"
CPLOGFILE="/var/db/captiveportal.db"

case "$1" in
 --help)
  print_help
  exit 0
  ;;
 -h)
  print_help
  exit 0
  ;;
 --version)
    print_revision $PROGNAME $REVISION
  exit 0
  ;;
 -V)
  print_revision $PROGNAME $REVISION
  exit 0
  ;;
 *)
  #Count the Captive portal Active Users
  count=`$WC -l <$CPLOGFILE`
  if [ "$count" = "0" ]; then # no matches, exit with no error
    $ECHO "No active users found on captive portal\n"
    exit 0
  else # Print total count
    $ECHO "$count active users found on captive portal\n"
    exit 0
  fi
  ;;
esac

Step 2 :Made it executable with

chmode +x /usr/local/libexec/nagios/check_cpactiveusers

Enjoy
