Nagios/Naemon check plugin: Checks Netscaler gateway vserver status.

Tested on CentOS 6.x, SCL Python v2.7

Requirements:

• SSL options requires Python 2.7+ to work correctly, this assumes that SCL Python27 is installed.

  yum install -y centos-release-SCL
  yum install -y python27 

• Citrix nitro-python api installed, download it from inside Netscaler appliance located: /var/netscaler/nitro/nitro-python.tgz unpack and install it: python setup.py install or install with SCL: scl enable python27 "python setup.py install"

nagios command template:

• set user macros USER47 and USER48 in resource.cfg, as username and password for Netscaler

 define command {
        command_name    check_netscaler_gateway
        command_line    $USER1$/check_ns_gateway.py --host $HOSTADDRESS$ --user '$USER47$' --password '$USER48$' --gatewayname $ARG1$ 
 }

Templates for HTTPS with/without cert verification, using SCL Python v2.7:

define command {
       command_name    check_netscaler_gateway_ssl
       command_line    scl enable python27 "$USER1$/check_ns_gateway.py --ssl --host $HOSTADDRESS$ --user $USER47$ --password $USER48$ --gatewayname $ARG1$ "
}

define command {
       command_name    check_netscaler_gateway_ssl_noverify
       command_line    scl enable python27 "$USER1$/check_ns_gateway.py --ssl --nosslverify --host $HOSTADDRESS$ --user $USER47$ --password $USER48$ --gatewayname $ARG1$ "
}
