Re: [nv-l] MIB data collection questions

[Mark Sklenarik <marksk@us.ibm.com>]

Justin,
In order to set "-u" you will
need to update the option for daemon through "serversetup" configuration
utility.

Do the following:
#. /usr/OV/bin/NVenvironment  
(to source netview environment first, that is "period space /usr..."
#serversetup
   > Configure 
   > Set Options for events
and trap processing  daemons 
   > Set options for snmpCollect
daemon 
   > Collect on unmanaged
nodes? = Yes (change from no to yes) 
   > OK
This will update the configuration of
snmpCollect daemon and restart it with the new option in place.
  > File > Exit  to
leave serversetup

Subject	Re: [nv-l] MIB data collection questions

According to the snmpCollect man page, I should be
able to use the "-u" 
argument to turn on support for data collection from unmanaged nodes, but
when I run "ovstart snmpCollect -u", ovspmd acts like it doesn't
understand the "-u" with error "ovspmd: Object manager -u
is not 
registered.  See ovaddobj(1m)."

So how to I either get this object to be seen as "managed" by
snmpCollect 
(preferred), or worst case tell snmpCollect to collect data regardless?

Thanks Jim. I turned up tracing and verbose and started collecting again
on sysUpTime, and got the following in /usr/OV/log/snmpCol.trace:

Well, offhand I don't see a problem.

What I would do is use xnmcollect (the GUI)  and suspend that collection.
Then issue first "snmpCollect -T" from the command line to turn
on full
tracing, and then "snmpCollect -V" to make it verbose.
Then use xnmcollect again to resume that collection, but lower the 
interval
to 2 minutes (you are testing after all).
Then wait for three minutes and go examine /usr/OV/log/snmpCol.trace.  If
there are problems, he should spell them out in detail.

the

Sorry left a critical piece of info out - I can also do a "test"
SNMP
collection against the sysUpTime value, and it tests fine and I get the
value, and it says it will collect for "0 instances"... which
I find
odd...

does that mean it will never collect even though I have it set to "ALL"
instances in the config? Not sure what I'm missing here...

MIB data collection questions

In addition, I'm having an issue setting up the MIB data collection that
I'm hoping someone has a quick answer to. I've followed the steps in the
Admin Guide, but can't seem to get this to work.

This is Netview 7.1.4 on AIX 4.3.3:

So far I've done the following:

I have a Solaris server running snmpd.
I seeded it and verified it was added to the map
I can do a test SNMP GET on it fine.
I loaded a MIB, host-resources-mib.mib, to collect against.
I configured Collection on a basic MIB value, sysUpTime, set it to
Collect, 5m freq, All instances, Store without Thresholds.
I right-clicked and selected "Manage" on the server object

When I look at snmpCol.trace, the data collection never begins, instead
it
says:

Fri May 20 15:11:19 2005 : Initializing for data collection...

Fri May 20 15:11:19 2005 : Nothing to collect.  If you expect data
to be
        collected, check that the nodes selected for
collection
        support SNMP, are up and managed, respond to
SNMP, and that
        the configured collections are correct and
not suspended.

I triple-checked all of the configuration, and restarted snmpCollect,
netmon several times, and also did an ovstop/kill OV processes/ovstart
to
be sure. Still getting the same message in snmpCol.trace.

What am I missing?

TIA,

MIB data collection questions



You did not say what platform you are running on. I can only really
address Unix (AIX). As for scalability, I think the capacity limitation
is

more on the devices being polled than on the Netview server. How busy are
they, and how much data can they spit out given the timeouts and retries
you specify. A few mib variables every 5 minutes can be a lot what with
today's devices having hundreds of interfaces. Many of the values you are
likely to want to poll are mib expressions like bandwidth utilization,
involving several mib variables, so that's another multiplier.

Netview does a nice job of combining the requests into bundles, and can
limit the size of the request, making multiple trips if necessary. This
makes it relatively efficient.

If you are talking hundreds of devices with hundreds of interfaces each
and want to poll in the 5 minute range, I would not feel positive. In the
15 minute range, I'd say maybe, if the box is big enough for everything
else going on. For thousands of devices and only a couple of mib values
every 15 minutes, that's probably ok too.

I have seldom seen the snmpCollect daemon hogging the cpu unless something

silly was configured.

I will say, however, that I am finding it less usable these days for data
collection on high-speed interfaces. The Counter32 datatypes it supports
cannot handle the rollovers. In fact, at some sites the Counter64
datatypes would not help. I see the rmon mib now has tables for reporting
counter rollovers, so you can monitor those instead of the actual counts.
Amazing.

So, let's hear it, everyone. What are you collecting, on how many
interfaces, how often, on what hardware, and what's the bottleneck?

Does anyone care to share their experiences (good or bad) using Netview
to


poll SNMP nodes for MIB data collection? Specifically, Netview 7.1.4, and
storing the MIB data in a flat file. How scalable was it? How many nodes
at what interval? On what hardware was Netview running?

Any information is appreciated.
