[Users] SNMPstats module not returning data

Hi list. I have installed Openser 1.2.0, with Net-snmp version 5.4 to support the SNMPstats module. I have configured the subagent according to the instructions on the documentation, but I am not being able to obtain any data. I am running both products on Solaris 10 Sparc. # /opt/net-snmp/bin/snmpwalk -v 2c -c community sipserver .1.3.6.1.4.1.27483.3.1.1.1.1.1.1 SNMPv2-SMI::enterprises.27483.3.1.1.1.1.1 = No Such Object available on this agent at this OID # /opt/net-snmp/bin/snmpwalk -v 2c -c community sipserver openserSIPProtocolVersion SNMPv2-SMI::enterprises.27483.3.1.1.1.1.1 = No Such Object available on this agent at this OID Is there any other thing I should do after compiling and configuring? Thanks in advance for your attention Kind Regards. Sergio Gutiérrez
