How the agent retrieves information about running processes depends on
the precise O/S you are using.
Checking the code, the 'pr_fname' field only appears to be used on
Solaris kit (reading this from /proc/{pid}/psinfo). Other systems use
a choice of ioctl calls (BSDi), the 'getprocs()' API (AIX), /proc/{pid}/cmdline
or /proc/{pid}/status (Linux), nlist (Ultrix), KVM (alternative on Solaris),
or by parsing the output of 'ps' (everything else).
You may need to do a bit of poking about to check with block of
code is active on your particular kit. See the (various) routines
'sh_count_procs()' in the file mibgroup/ucd-snmp/proc.c
