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.

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 Taokeer

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.

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...

Subject: [nv-l] Inventory
management through NetView
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?
