Database Query Monitor Settings
Checks that a database is working correctly by connecting to it and
performing a query. Optionally, it can check the results of a database query
for expected content.
Use this page to add the monitor or edit the monitor's properties.
To access: Select the Monitors context. In the monitor tree, right-click a
group, select New > Monitor, and select the monitor from the New
Monitor Page.
Monitors must be created in a group in the monitor tree.
The Database Connection Tool is available when
configuring this monitor to test and verify connectivity
between SiteScope and an external ODBC or JDBC
compatible database (provided you are an administrator in
SiteScope, or a user granted Use monitor tools
permissions). To use the tool when configuring or editing a
monitor, click the Use Tool button. For details on the tool,
see Database Connection Tool.

Database Query Monitor Overview
The monitor specific settings are described below. For
details on the settings common to all monitors, click here.
Database Query Monitor Settings
The following elements are included (unlabeled GUI elements are shown in angle brackets):
Database Enter a URL to a database connection (no spaces are allowed in the URL). One
connection way to create a database connection is to use ODBC to create a named connection
to a database.
Example: First use the ODBC control panel to create a connection called test.
Then, enter jdbc:odbc:test as the connection URL.
Note for using Windows Authentication: If you want to access the database
using Windows authentication, enter jdbc:mercury:sqlserver://<server name or
IP address>:1433;DatabaseName=<database name>;AuthenticationMethod=type2
as the connection URL, and com.mercury.jdbc.sqlserver.SQLServerDriver as
your database driver. Leave the Database user name and Database password
boxes empty, because the Windows user credentials of the account from which
the SiteScope service is running are used to establish a connection to the database.
Enter the java class name of the JDBC database driver.
The default driver uses ODBC to make database connections. SiteScope uses the
same database driver for both primary and backup database connections.
If a custom driver is used, the driver must also be installed in the <SiteScope root
directory>\WEB-INF\lib directory.
Default value: sun.jdbc.odbc.JdbcOdbcDriver
Database Enter the user name used to log in to the database.
user name If you are using Microsoft SQL server and the default driver (Sun Microsystem
JDBC-ODBC bridge driver, sun.jdbc.odbc.JdbcOdbcDriver), you can leave this
blank and choose NT Authentication when you setup the ODBC connection.
With NT Authentication, SiteScope connects using the login account of the
SiteScope service.
Note: The specified user name must have privileges to run the query specified for
the monitor.
Enter a password used to login to the database.
If you are using Microsoft SQL server and the default driver (Sun Microsystem
JDBC ODBC bridge driver (sun.jdbc.odbc.JdbcOdbcDriver), you can leave this
blank and choose NT Authentication when you create the ODBC connection.
With NT Authentication, SiteScope connects using the login account of the
SiteScope service.
Enter the SQL query to test.
Example: select * from sysobjects
Enter a string of text to check for in the query result. If the text is not contained in
the result, the monitor displays no match on content. This works for XML tags as
You may also perform a Perl regular expression match by enclosing the string in
forward slashes, with an i after the trailing slash indicating case-insensitive
Example: /href=Doc\d+\.html/ or /href=doc\d+\.html/i
If you want a particular piece of text to be saved and displayed as part of the
status, use parentheses in a Perl regular expression.
Example: /Temperature: (\d+)/ would return the temperature as it appears on the
page and this could be used when setting an Error if or Warning if threshold.
The search is case sensitive.
You can click the Open Tool button to use the Regular Expression
Test tool to check your regular expressions. For details, see
Regular Expression Tool.
File path
Enter the name of the file that contains the query you want to run. The file should
be in a simple text format.
Use this function as an alternative to the Query text box for complex queries or
queries that change and are updated by an external application.
Enter the field labels for the two columns returned by the query, separated by a
comma (","). These column labels are used as data labels in SiteScope reports for
Database Query Monitors.
Note: The field labels should be two of the labels that are returned by the Query
string entered above.
If you are reporting monitor data to an installation of HP Business Availability
Center, enter a text identifier describing the database server that this monitor is
monitoring. This text descriptor is used to identify the database server when the
monitor data is viewed in an HP Business Availability Center report.
Database Connection Settings
The Database Connection Settings enable you to retrieve, share, and reuse
database connections for database monitors that use any JDBC-compliant
driver. When multiple database monitors use the same database, using a
connection pool instead of an open connection for each monitor improves
monitor performance and optimizes database server resource utilization.
Connections can be shared regardless of monitor type. For example,
SiteScope database logger, database tools (Database Connection, Database
Information), database alerts, and database monitors (Oracle Database,
Database Counter, Database Query, DB2 8.x and 9.x, Technology
Database Integration, and so forth) can share and reuse database
connections in a connection pool.
You can set additional database options that affect all resources that
connect to the database in the JDBC Global Options in Preferences >
General Preferences.

The following elements are included (unlabeled GUI elements are shown in angle brackets):
GUI Element
Use connection
Enables SQL connection sharing. This means that you use a
connection pool rather than open and close a new connection for each
monitor query.
Default value: Selected

count exceeds
are closed rather than returned to the connection pool.
Default value: 10
Idle connection
The maximum amount of time, in seconds/minutes/hours/days, that a
SQL connection remains unused after it has been returned to the SQL
connection pool. When the time is exceeded, the connection is
automatically closed.
Default value: 5 minutes
Query timeout
The amount of time, in seconds/minutes/hours/days, to wait for
execution of a SQL statement. Not all SQL drivers have this function.
If your SQL driver does not support this function, this parameter is
Default value: 1 minute
