Nagios Support Forum

I have new requirement of monitoring Number of user connection on Citrix server.

Is there any plugin available for achieving this ? Its Windows server.

There are a few plugins that achieve this. You can find them on the Nagios Exchange:

i am using Check_ SNMP_ Citrix plugin.

I have placed this plugin in /usr/local/nagios/libexec/ (NagiosXI Server)

Using NagiosXI, how can i call from XI to remote server (windows). Where i have to look & do the necessary changes or command definition. I am not sure.

Take a look at the Managing Plugins doc in our admin manual, that should cover how to turn a new plugin into a service check:

do i need to installed this snmp4tpc on client machine ? its zip file & after extracting i am getting MIB file.

Looking at this specific plugin it does look like you will need to install the MIB on the Nagios server Admin -> Manage MIBs, as well as follow the install documentation in the ZIP.

I don't have a system to test this on, if you are just looking for the count only you may want to look at one of the other plugins abrist mentioned.

Upload MIB files in nagios. Also followed document.

but when i am trying to run below commnad under /usr/local/nagios/libexec
Got this message
./check_snmp_citrix 10.105.32.96 public WFActive
Timeout: No Response from 10.105.32.96.
USERS OK - users currently logged in |User=;;;

From the XI server can you run If not I would guess that either there is a firewall blocking access to SNMP on 10.105.32.96 or the SNMP service isn't running on 10.105.32.96 or finally, public isn't the SNMP community string...

Done the necessary changes. Now able to communicate with the server & below is output.

# snmpget -v 1 -c public 10.105.32.96 sysUpTime.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (778) 0:00:07.78

But when i run below command under libexec, i am not getting count of users logged in

# ./check_snmp_citrix 10.105.32.96 public WFActive
USERS OK - Such users currently logged in |User=Such;;;

I just looked at the Exchange page for the plugin you are using and there is a review that says the same thing.

You will need to contact the plugin author dudleyperkins_AT_gmail.com this is likely a bug.
