Surveillance
DB provides a facility to display
an extensive set of predefined windows that provide an immediate
global view of database activity and detailed performance metrics
such as session/process activity, locks, batch contention,
file I/O, and much more. Real-time data from multiple RDBMS
can be viewed simultaneously. Data from each window can be
sorted or filtered while most statistics can be graphed over
time. In addition, each window or graph can be configured to
refresh at either the default collection interval or its own
refresh interval.
Easy
Installation
Surveillance DB installs
in only minutes and is able to be configured to begin monitoring
right away.
Flexible Agent Architecture
Agents can run directly
on the server (native agent) or in a multi-tiered configuration.
This allows you to configure your agents to your business requirements,
and you are not bound to some pre-determined architectural restriction,
such as a centralized console. With Surveillance DB, you
can monitor all of your Oracle, Sybase or SQL Server databases from
either a single or multiple console configuration through an intuitive
graphical user interface.
Real-Time Monitoring
Surveillance DB is a real-time monitoring tool capable of overseeing
your entire database environment. A DBA can view
real-time performance data without writing scripts, reducing
the need for a large, skilled staff to trace problems. The Surveillance
DB Module deploys an analytical drill-down methodology for quick problem
identification.
For example, Surveillance DB for
Oracle provides a set of pre-defined windows that are used to immediately
display real-time information for a variety of performance statistics.
Highlighting an entity under the Oracle agent displays a context
toolbar at the top of the screen. The buttons on this toolbar represent
the primary windows available for real-time monitoring. The buttons
available depend upon the version of the Oracle database that is
highlighted.
If the first button on the context-specific
toolbar was clicked, a Global window would be opened for the corresponding
database on that server, displaying important statistics regarding
the status of the Oracle instance. Double-clicking on a line in
a window allows you to go deeper or to "drill-down" to
start a time-line graph for that statistic.
The Analyzer
Surveillance DB has an extensive alerting and alarming facility
that comes with a large set of pre-defined collections and rules. To
begin monitoring, the DBA uses these pre-defied rules to easily adjust
default values and collection intervals before turning on the
rules to be monitored.
User-defined Collections
The Surveillance DB Collector Agent is responsible
for collecting the performance data from the entity via pre-defined
collections. The data must first be collected by the collector
agent before data can be used by the analyzer or repository agent
for the Event Management and Historical Repository features.
In the past, the end-user was limited to alerting and adding
pre-defined collections to the repository, and was unable to
modify or add new collections. With Surveillance DB,
a facility exists for users to create user-defined collections
that can be used with the Event Management and Historical Repository
features.
User-defined Repositories
The Repository Agent is a process that stores historical
performance or application data from any pre-defined or user-defined
collection. Historical data is retained in named stores, which
have user-specified time intervals and duration. An interval
compression algorithm is used to minimize disk utilization.
Data from the repository is used to
obtain a historical perspective when the Surveillance DB's
Event Management feature detects and alerts the DBA that conditions
are occurring that are negatively impacting performance. Data from
the Repository can be used to trend performance and space utilization
data; or the DBA could use the data to establish baselines for
threshold values in Event Management's rule definitions.
Any ODBC-compliant reporting tool
can be used to query and/or graph the historical data.

Multiple Action Event Handling
Right out of the box,
Surveillance DB can be easily set up to notify multiple DBAs by
e-mail, pager, HP Openview or Tivoli alerts, pop-up windows, or
to record the error in the Windows Event Log. The DBA can also
execute a fix-it job by executing any operating system executable,
including SQL*Plus and ISQL.
Surveillance DB automates
the monitoring process through rules analysis
and event generation. From these events, the system
determines the actions that need to be taken. This process begins
by defining and applying data rules in the Analyzer Agent. When
the agent is started, it loads its rule set, attaches to the appropriate
data collections, and begins a continuous process of evaluating
rules. If a rule has been satisfied (for example, something noteworthy
has occurred) it generates an event that is sent to the local alerter.
The Alerter receives the event, and determines which, if any, Event
Handler is appropriate for handling the event.
Repository
Surveillance DB provides a mechanism for storing data collections
to a repository for reporting and analysis. This process begins by defining
data stores in the Repository
Agent. When the agent is started, it loads its list of
defined data stores, attaches to the appropriate data collections, and
begins its continuous process of storing data.
Data Store
definitions inform the Repository Agent what
to store, how often, and for how long. Data Store definitions
must be specified for the desired server entity and collection.
A Repository Export Program can be
used to export the data obtained in the Repository partitions.
Once the repository data is stored in a comma-delimited ASCII file,
it can be imported to a spreadsheet or database. This facilitates
statistical reporting to analyze the performance data being monitored.
Unlimited Client Installs
With the purchase of the
Surveillance DB Server Agent, you will be able to install
the Client on an unlimited number of machines.
Surveillance Reporting Module
The Surveillance Reporting Module is a combination of several technologies
and features that together provide the customer with a comprehensive
reporting system. There are three major components to this module: the
local host-based repository, the centralized repository, and the reporting
system.
- Local Host Repository Collection
and Reporting
- Surveillance Centralized
Repository
- The Surveillance Reporting
Module
With either added solution, customers
can create their own report specifications and use the predefined
Surveillance report specifications.
