RE: [nv-l] Routing table pulled

[James Shanks <jshanks@us.ibm.com>]

That's why I asked if you had a problem.   Most people don't configure this
value unless and until they do have one.   But if you are simply worried
you can do it ahead of time.   And as I said, the Help says the default
value is 800, so we wouldn't query 6000 even in the default  or
un-configured case.

But netmon doesn't query the routing table without a purpose, especially
during discovery.  That's an important part of how automated discovery
proceeds.  So I'd say that zero is a little drastic, wouldn't you?
With zero you may halt automated discovery.  Or you may get unconnected
nodes or networks on the map.

Do I need it configured at all?  Apparently, this person's concern was
under HPOV, that when it discovered a router, it made 6000 individual
snmp get statements for each routing statement.

What is the impact of setting this to 0?

This is configurable in xnmsnmpconf, under the field "Number of Route
Entries".

Default is 800 according to the Help, which you can verify yourself.  If
you think a max of 800 is too high you can set something else.

Are you having a problem or just worried about one?

Folks:


Apparently, under hpov, when a router was discovered, the entire routing
table of the router was pulled as well, causing the cpu to spike because
it pulled one route at a time.  Does NV do the same thing when it
discovers a node?


Thanks
