Sorry,
for
'Dumping data' read 'Dumping,
redundant, useless, pointless, repeated, duplicated, <insert word(s)
here> data'
Flame
off :-)

Ah,
thats where the Network support people earn their corn. I just let them
know there is a problem and they check it out... They have all manner of black
arts available to them - IP accounting - Network probes etc, but mainly
its he who shouts loudest is probably to blame - have a look at their
application server and you normally see alot
of activity, Dumping data onto heavy clients over WAN links must be
my favourite.

Inventory management through NetView
Collin,
Thanks for the kind
info, I'll try using the expressions you specified, one thing how do you
that who is the culprit application? I mean NetView does not work on
application layer how does it recognizes that the specific application is
hogging the bandwidth?

Usman,
For
bandwidth utilisation we use the expressions BandwidthUtilIn and
BandwidthUtilOut to collect utilisation on routers. Setting a
threshold is also a neat feature of the collection we have found it very
useful in catching applications flooding the lines - we set the threshold at
90% utilisation with an E-Mail alert and the re-arm at 80% When the
alert comes in we can catch the offending app 'red handed' its great fun
showing the 'blame monkeys' that its actually their fault...:-)
I saw
a discussion recently on nv-l which may provide more elegant solutions for
management reporting... I will be looking into trying these solutions myself
when I get time - they seem to provide a better solution to the one I am
using now.
If I may be so bold I would recommend that you check out
the solutions outlined in the discussions board (see links below) as a more
permanent solution to your requirements.
http://lists.skills-1st.co.uk/mharc/html/nv-l/2005-04/msg00124.html
and
http://www.nv-l.org/twiki/bin/view/Netview/NvAvail
I
would be slow to share the scripts that I use here as they are unique to my
site, I built them up from very basic alerting scripts into a quagmire of
code calling code reading from logfiles generated by yet more code.
All in all not very portable.
I have included one PERL script that
you may find useful (even as a starting point). It reads from a output
file from graphed data (snmpCollect), formats the timestamp and puts the min
ave max in comma delimited format. (You will probably have to change the
path to the output file)
**NOTE** As I always say I take no
responsibility for the performance of the script and I know that its ugly
and probably inefficent - but I'm not paid to do pretty

Collins,
Hey thanks for the wonderful info on reporting techniques,
actually i 've been searching for a reporting tool for a certain project and
we were considering Magnum's CAP-Trend but the price was redicullious,
you've showed me a new way for that, can you kindly share how do u generate
reports on network performance (availability,downtimes,link utilizations
etc, u know what managment asks for).
Actually its for a customer who has outsourced
their entire IT to us so we need to present them some reports on the
performance of the network for that we are using TEC+DatawareHouse all i
need is to find a way to extract info from the DataWarehouse in form of
NetWork Performance etc.
Can you share your scripts and how you transform
that info into MSExcel? We are using NV 7.1.4FP3 on Windows BOX.
For Bandwidth
utilization are you using ifInOctets, i tried using that but it shows me the
sum of bits coming in/out, (the counter/value is always increasing) am i
missing something, i was trying to monitor our E1 links terminated on a
Cisco 3745 Router!

Usman,
You could try setting Definition 2 to isNode = TRUE
(so the smartset true for sysObjectID AND isNode). If the
isNode does not work I would compare the ovobjprint output for the switch
entry and the vlan entry and look for something unique to either and filter
on that.
As for prettifying the reports for management - ah yes I know it
well - I do not store NetView Data in Datawarehouse so I do not know whether
it would be useful or not. I briefly tried DB2 on the netview server
but performance degradation made me change back to flat files very quickly
(anyway I think that there were licencing issues with how you can use the
data in DB2 for NetView).
What I normally do with any reporting
requirements is to write a script to extract what I need to a csv file and
use MS excel to generate the reports and graphs. We run NetView
without discovery switched on so we manually manage what goes into the map,
hence I do not get many requests for reports on the hardware inventory.
There is only an ongoing requierment for reporting on alerts (network
connectivity and performance). I manage all alerts through inhouse scripts
(fired from trap generated events) so I can format and log exactly what I
need and I use NetViews snmpCollection for ongoing bandwidth utilisation
reporting.
None of which is probably of much use to you but, its good to
share.

Collins,
Thanks dude, i found all the description in
the Manual for UNIX. But i still am facing one problem. We have VLANs
created and for each IP network NetView considers is as separate object and
hence i have multiple entries for One Switch in the Smartset coz the OID is
same for all (obviously), is there a trick around any other way that it
doesn't count it again if it exists already in the database, any other
Unique ID like MAC or something?

Usman,
You can create a smartset and set the SNMP sysObjectID
= 1.3.6.1.4.1.9.324 (the ID for a 2950/24 switch) - You can get the ids for
all cisco kit at www.cisco.com - (I found the 2950s at http://www.cisco.com/en/US/products/sw/cscowork/ps2406/products_device_support_table09186a00800b5e7f.html )
Smartsets 101 (UNIX) If you have not
created a smartset before... From the Tools menu Open Smartset Editor - Add
- (give your smartset a name and discription) - click the modify
button for definition 1 (ensure Definition Type is set to Attribute) Find
the SNMP sysObjectID attribute and set the string attribute value to =
1.3.6.1.4.1.9.324 Then click OK. You can test the definition
(click test) this will give you a list of all matching objects. Click
OK and the new smartset gets created.
If you install the Cisco - NetView
integration kit the smartset editor has a cisco attribute - can be useful
(you also get natty cisco icons for the map - not alot else though, as far
as I can see)
I am sure that other manufacturers also supply the sysObjectID
mib values for their kit too.
Happy smartsetting...

Dear
list,
Can we
keep a track of inventory (switches,routers models) in NetView. I read it
can be done using smartsets but don't know how exactly. Like if i want to
make a smartsets for all Cisco 2950 switches how do i do it? or is there any
other way to keep a track of that?
