This is normal for the same type-instance for different devices  
(hosts) yes.

As long as the input plugin of both is working, then rrdfiles should  
be updated.

Have you tried to enable another outputplugin , like csv, to check if  
the data is updated there ? If it is not , I would suspect input  
plugins. If it is I would suspect the rrd plugin.

Have you looked at the logfiles ? Debug options of collectd ?

You can also try tcpdumping snmp traffic between your collectd server,  
and snmp hosts that is not updating, to check if snmp get requests  
actually is sent, and data is received. (Assuming you use snmp plugin)
