  I used OpenView extensively for 9 months last year (until I left my former 
  company).  I developed an management system for data acquisition systems that
  was demoed at last summers IEEE Summer Power Meeting.  I felt it is 
  an excellant product and pretty solid, even though I
  started with pre-release versions.  I know they have a least 1 newer version 
  that may make it easier to develop managers and applications.  It is very 
  powerful but big.  An analogy I use is that is comparable to Xlib what we need
  is an Xt layer with widgets on top of the current system.

  I was working on this by encapsulating OpenView inside of C++ classes.  My
  two main classes were ObjectManager and ManagedObject.  I was pretty close to
  getting it working before I left my old company.

  HP was considering building a code generator for the managed objects.  I hope
  that they still provide a simpler programatic interface for those of us who
  would rather roll our own.

  I don't know about products but that was the problem I was working on.
  I was designing a system to manage our applications and servers.  Most of
  our servers are NCS based so I defined an interface that all servers must
  support.  Then the server manager takes the OpenView requests and turns around
  and makes an NCS request to the appropriate server.  The server manager handle
  requests for starting servers, killing them, etc.

  I felt this approach was reasonable to avoid having to put OpenView support
  in our servers or NCS support in our management applications.

    I have no idea about this.

>(3) What ever became of CMOT? Do any agents speak that protocol?

   OpenView uses CMOT and SNMP through the same interface.  In some configuration
   file you define attributes for the managed objects, one of the attributes is
   whether it supports SNMP or CMOT. Hp's snmpd will connect to the OpenView
   server if one is running.

   I think supporting both protocols is a real benefit, I believe that it will
   allow smoother integration of managed objects whos agents speak SNMP, CMOT, 
   or CMIP (when it comes).

Although this should have been at the top of my message, I haven't used OpenView
since the end of january so I may have forgotten some things or unaware of 
recent upgrades.  I do feel that is an excellant product and should be seriously
considered.
