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.
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

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...

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?
