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? Regds, Usman Taokeer
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 Regs Colin M. -----Original Message----- From: owner-nv-l@lists.us.ibm.com [mailto:owner-nv-l@lists.us.ibm.com] On Behalf Of usman.taokeer@s-iii.com Sent: 14 July 2005 15:55 To: nv-l@lists.us.ibm.com Subject: RE: [nv-l] Inventory management through NetView 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! Regards, Usman Taokeer Si3.
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.

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? Regards, Usman Taokeer Si3.
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...

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?
