Following on from Paul's excellent Tivoli Support Technical Exchange
presentation on NetView discovery, I asked a question about the use of
@limit_discovery in a netmon seedfile. Does anyone know definitively
what it does??
My understanding goes like this:
There is a "master" auto-discovery on/off switch that can be applied on
a Unix NetView from Options -> Topology status Polling. If
auto-discovery is set to off then netmon only discovers EXPLICIT entries
in the seedfile; wildcards and ranges will have no effect.
If auto-discovery is on then wildcards and ranges can be used in the
seedfile. The IMPLICIT imperative in a seedfile with any wildcard or
range is that anything OUTSIDE the explicit entries, wildcards and
ranges will NOT be discovered. As Paul pointed out, a wildcard or range
does not actively go out and find anything - it simply means that if the
auto-discovery process finds a node that is included in a wildcard or
range, then it will be permitted into the NetView object database.
If these 2 understandings are correct, why use @limit_discovery? Either
turn the "master" auto-discovery switch off and simply find explicit
entries in the seedfile, or, if you want to use ranges with the master
switch on, how does @limit_discovery in the seedfile limit discovery
beyond the normal exclusion of objects as described above?
If we get a good thread running on this, perhaps we could move it to the
NetView Tivoli User Group website for more in-depth discussions?
Cheers,
Jane
