2-2 Architecture and Data Flow
This section gives a brief overview of the architecture of OVNPM. The following figure shows the consolidated
data flow between the HP NonStop environment and the Windows workstation or HP Operations management
server provided by OVNPM.

The consolidated view provided by OVNPM architecture helps maximize the availability of the system and
increase the productivity of your operations staff.
The OVNPM component on the HP NonStop Server consists of Basic Collectors, which collect information from
the Measure subsystem and send it to the Collect Manager. One Basic Collector is present per CPU, with the
maximum of 16 CPUs. The Collect Manager aggregates the collected data, builds new counters/matrix as per
the Measure counters, and sends them to the OVNPM Database Server.
The Database Server saves the collected data into the following databases:
• Trend Database
This is the long-term database with the granularity of one hour. One file is created per year for this
database.
• Insight Database
This is the short-term database with a granularity of 30 seconds, based on the collect interval. One file is
created per day for this database.
• Report Database
This presents the current system activity in tabular format. The database contains the most consuming
processes detected during a collect interval.
