Re: [NV-L] Netview Recommendation Required!

The issue you will have if you need MLMs is that neither the Linux nor
the Windows NetView Server support configuration of an MLM.  The AIX and
Solaris flavours have both a menu option to bring up a menu-driven way
of configuring an MLM of any architecture (smconfig tool)  AND AIX and
Solaris have the APM machanism for configuring remote MLMs and
distributing these configurations.

That said, if all you want your MLMs for is to drop unwanted TRAPs, then
your MLM configuration job shouldn't be too horrendous.  I suggest you
look at the MLM manual (it's a separate book) and also look at a default
MLM  config file - you would typically find this under
/var/adm/smv2/mlm/config.  Basically you will have to hack the MLM
config file manually and you will need to develop a mechanism for
getting the appropriate config file to each remote MLM.

Cheers,
Jane
