RE: [NV-L] How big can a seedfile be

["Kain, Becki \(B.\)" <bkain1@ford.com>]

i had thought about having little seedfiles, in fact, that is what we were initially doing but because there's no "okay, I'm done" message in netview, I'm never certain when to swap out to the next one.

One thing you could try is to take 
the IPs of a small group of devices that aren't being discovered and add them to 
a new seedfile. Then temporarily configure netmon to use that seedfile and see 
what happens. May want to copy all your entries that have polling/processing 
directives as well, just for good measure. 

I'm not really sure what is or isn't standard practise for the majority 
of customers, but I'd say that a "best practise" could be to remove entries from 
the "active" seedfile that have already been discovered (no need to seed them 
anymore). You can always keep a master copy of a seedfile that has every single 
IP you would like to store in a seedfile for some other later use. 

The only entries you need to keep in an 
active seedfile are those with  "directives" such as HSRP (%)  or SNMP 
Status polling ($) or the locking of the SNMP Address (=), etc. All other 
entries can be removed once discovered. 

Cheers, 
Gareth

Subject	Re: [NV-L] How big can a seedfile be

Ford had a PMR opened in 2003 to ask that question 
and the answer was pretty big, as I recall. However I think it is possible that 
the problem is that when you specify every address, then at startup netmon is 
going to check on every address whether it exists or not. I think I would enable 
tracing on netmon, then watch netmon.trace when you do a netmon -y. It posts a 
message when it is done loading that includes the word "sucessfully".  Try 
putting a misspelled node name at the end and see if the reload calls it out. If 
you ping the address you are looking for (from the commandline) and grep it in 
netmon.trace, you will see if netmon is getting around to trying to add it or is 
trying but giving up for some other reason.  It's just not how it was 
intended to be used, so it is not optimized for it. 

As for the link business, I 
just tried it and it worked fine. Moved a seedfile to somewhere else, and added 
a link where it was, and did a netmon -y. The resulting message in netmon.trace 
says it was loaded successfully.

What is the limit, if there is 
one, on the size of a seedfile?  Right now, mine is huge:

-rw-rw----  1 bkain1 bkain1 16783342 May 23 19:07 seedfile (this is on suse linux 9)

And it seems like the addresses that were added at the end are not getting discovered, yet I can snmp walk them.  And can the seedfile a link, as specified in netmon.lrf, or does that have to be the actual file listed?  Thanks_______________________________________________
