Hi,
Sorry for creating a new thread, it could be argued that this should belong
under my previous
thread. It is related, but is also a different query. My home machine pops off
my mail (due to some
mail probs) and I don't have access to the thread here in the office.
I posted the following patch to the users list (it was intended for the coders
list). It solves the
behaviour of collecting the used memory of 64 bit applications when the agent
is compiled as 32 bit
binary.

The problem is that for the sparc,
+ mem = netsnmp_memory_get_byIdx( NETSNMP_MEM_TYPE_PHYSMEM, 0 );
gives correct values, but for the amd/intel machines it gives 0 values
for the sparc,
+ mem = netsnmp_memory_get_byIdx( NETSNMP_MEM_TYPE_PHYSMEM, 1 );
returns zero values and returns correct values for amd/intel
I can add an #ifdef _sparc, but solving the problem might require a more
fundamental change. Is
there someone that can give me advice on how to use this function correctly?
Best regards,
Frans Grotepass
