snmp__rdp_users - Munin plugin to monitor the number of remote users connected to a Microsoft Windows Remote Desktop server.
Microsoft Windows servers running Remote Desktop Services (or Terminal Services, as it used to be known). It requires an SNMP server to be enabled on the machine to be monitored.
As a rule SNMP plugins need site specific configuration. The default configuration (shown here) will only work on insecure sites/devices.
[snmp_*] env.version 2 env.community public
In general SNMP is not very secure at all unless you use SNMP version 3 which supports authentication and privacy (encryption). But in any case the community string for your devices should not be "public".
Please see 'perldoc Munin::Plugin::SNMP' for further configuration information.
The number of users currently logged into the Remote Desktop server.
This plugin requires support for the HOST-RESOURCES-MIB (RFC 2790). It reports the hrSWRunName column of hrSWRunTable.
#%# family=snmpauto #%# capabilities=snmpconf
Unlikely to work on non-Windows RDP servers, since it relies on the name of the server process being 'rdpclip.exe'. But is there even such a thing as a non-Windows RDP server?
