Oh. NT. Well, I think all of us have probably had more trouble
with data collection on that platform than on Unix, but it should
not be as bad as you are seeing.
One suggestion. I have sometimes had a problem, even on
AIX, when name resolution has changed. The snmpCollect
daemon does not handle this sort of thing exactly the way
the rest on Netview does. For a node that has been a problem,
try deleting the collection definition for it and re-defining it. That
will let snmpCollect get new information about the name of
the object and its community string.
Two other things to try. One, reduce the deferral period from
the default (an hour?) to something like 5 minutes. Smaller
holes. Also, if you are asking for a variable that occurs in large
numbers, say ifInOctets across all interfaces of a router with 100
interfaces, tell snmpCollect to ask for data in smaller chunks. On
AIX this is one of the snmpCollect configuration options, maxpdus or
something. So I'm sure it is an option on the NT version as well.
Often a device will not be willing to give a 'long answer' but
it will give multiple short answers. This could be the cause of the
problem with snmpCollect, which tries for everything at once,
while snmpwalk still works; snmpwalk is completely different code.

snmpCollect for stats reporting

Sorry this one is sooo late - just found it in my drafts folder - duh
(having some ISP problems)! Thought I'd send it anyway...
I hoped that was the case.
I'm doubting it because it's not working properly - the collections are
either always deferring or returning zero values where there should be
one (deferral is proportionally the worst problem in terms of
occurrance). I've checked with snmpget/walk/nv mib browser from the NV
box that the data is there and accessible & it's all fine. The NV box
CPU/RAM are barely used & since the routers response to snmpget/walk etc
I can't see why snmpCollect defers. I've "tried" tuning snmpCollect,
but to no effect.
I've raised a PMR for it but I was wondering if I was flogging a dead
horse (w2k, sp2, nv 7.1.2/7.1.3).

I wonder why you would doubt it. I can vouch for it. I've used it for
years in about a hundred different customers' networks. For collecting,
that is. It is quite efficient and I would not consider writing a tool
to do it. Dump the data to a relational database for easiest external
reporting with the tool of your choice.

snmpCollect for stats reporting

Hi list,
Just wondering if anyone is reliably collecting SNMP data through
snmpCollect for stats reporting? I'm thinking about doing this on
Solaris with NV 7.1.2. I only need to collect from about 40-50 devices,
approx 15 mins intervals and around 4 mib values per device.
I'm going to feed this into rrdtool to graph up, but a just debating
using snmpCollect or writing some scripts to snmpget the values (or mrtg
depending on how complex that it to setup).
thanks in advance
Karl
