components and present some similar information but are typically used for slightly different
purposes:
•
You use the Dashboard client to monitor queries and system resources on the Neoview
platform and to reveal, as soon as possible, if some aspect of system performance is outside
an acceptable range. The Dashboard client is a graphical user interface (GUI) that displays
current and recent data on color-coded graphs and accompanying grids. It includes a
Command and Control facility with which you can kill a running query.
•
You use Repository queries to study patterns of resource utilization over time, for example
to find out how many queries from each of several data sources occurred during specific
time intervals.
Runtime statistics for queries are synchronized in the two products; in fact, the data collection
interval is configured in the Dashboard. Similarly, much of the data available for Tables and
Disk entities is initially obtained by statistics gathering processes (SGPs) in the Dashboard, and
the Dashboard configuration affects which Tables and Disks are represented in the Repository.
If any of the QueryRTS, Table, or Disk SPGs are turned off in Dashboard, there will be no data
in the Repository for the corresponding Repository entity. As the Repository receives all the data
from Dashboard for these entities, the configuration of Dashboard will affect the Repository.
NOTE:
Because the Query Runtime Statistics feature updates the Repository as new query
statistics information is received from the Dashboard, you can now use a standard SQL interface
(such as the Neoview Command Interface) to monitor running queries on a Neoview platform.
The figure labeled
illustrates, at a very high level, the architectural relationship and
interfaces of the Dashboard and Repository. This manual describes only the user interface of the
Repository, which allows you to create and display the results of Repository queries on any
standard SQL interface. HP Support has access to additional tools for managing the Repository
configuration.
