Joe,
Thanks for your reply.
I did turn on the trace and looked at the trace file. The only useful
message was
"hostname doesn't reply to xx(number) object PDU, but responds to sysUpTime.
Be sure timeouts are not set too small (SNMP interval 20.00s retry:3)."
I have checked the manual, it only says the definition (and the defaults)
but no consequences (or examples).
Regards,
David

David,
I suggest you turn on tracing of snmpCollect with the -T switch if you do
not already have it on, and then look at the trace file snmpCol.trace,
which is in /usr/OV/log. Check what happens as you increase the number of
collection instances.
snmpCollect parameters are documented in the man page which is in
/usr/OV/man/man8. I had a quick look at a Solaris system here and it seems
to me the NetView environment script does not get the path right for the
man pages.
