6.2.3.2 Tivoli NetView Hardware Monitor/NPDA

Tivoli NetView Hardware Monitor, formerly known as the
Network Problem Determination Application (NPDA) product,
provides you with diagnostic and reliability data, including
component error statistics and traffic volumes.  Its online
functions are designed to assist network operations in
resolving problems quickly.

The NetView Hardware Monitor also produces the NetView
reports record, which can be directed to SMF as the type 37
subtype 3 record.  The CA MICS Network Analyzer processes
this SMF record to add diagnostic and reliability data to the
CA MICS database.


DATA TYPES

The information recorded by the NetView Hardware Monitor
consists of the following:

  o  Statistics--records of communications traffic and
     temporary (recoverable) errors

  o  Events (generic and standard)--either specific errors
     reported by communications devices or statistics that
     exceeded the installation-defined threshold for the
     error-to-traffic ratio

  o  Alerts--events that qualify for alert status as a result
     of the analysis by a user-defined Alert recording filter

The installation controls what qualify as events and alerts,
and must define these qualifications so that critical
information is recorded.  The installation also controls the
number of NetView Hardware Monitor/NPDA reports records
produced through the recording filters.
