Method Detail

getConfig

public java.util.Properties getConfig()
                               throws ConfigPropertyException

Get the "root" server configuration, that means those keys that have the NULL prefix.

Returns:

Properties

Throws:

ConfigPropertyException

getConfig

public java.util.Properties getConfig(java.lang.String prefix)
                               throws ConfigPropertyException

Get the server configuration

Parameters:

prefix - The prefix of the configuration to retrieve.

Returns:

Properties

Throws:

ConfigPropertyException

setConfig

public void setConfig(AuthzSubject subject,
                      java.util.Properties newProps)
               throws ApplicationException,
                      ConfigPropertyException

Set the server configuration

Throws:

ConfigPropertyException - - if the props object is missing a key that's currently in the database

ApplicationException

setConfig

public void setConfig(AuthzSubject subject,
                      java.lang.String prefix,
                      java.util.Properties newProps)
               throws ApplicationException,
                      ConfigPropertyException

Set the server Configuration

Parameters:

prefix - The config prefix to use when setting properties. The prefix is used for namespace protection and property scoping.

newProps - The Properties to set.

Throws:

ConfigPropertyException - - if the props object is missing a key that's currently in the database

ApplicationException

analyzeNonMetricTables

public long analyzeNonMetricTables()

Run an analyze command on all non metric tables. The metric tables are handled seperately using analyzeHqMetricTables() so that only the tables that have been modified are analyzed.

Returns:

The time taken in milliseconds to run the command.

analyzeHqMetricTables

public long analyzeHqMetricTables(boolean analyzePrevMetricDataTable)

Run an analyze command on both the current measurement data slice and the previous data slice if specified.

Parameters:

analyzePrevMetricDataTable - tells method to analyze previous metric data table as well as the current.

Returns:

The time taken in milliseconds to run the command.

vacuum

public long vacuum()

Run database-specific cleanup routines -- on PostgreSQL we do a VACUUM ANALYZE. On other databases we just return -1. Since 3.1 we do not want to vacuum the hq_metric_data tables, only the compressed eam_measurement_xxx tables.

Returns:

The time it took to vaccum, in milliseconds, or -1 if the database is not PostgreSQL.

getConfigProperties

public java.util.Collection getConfigProperties()

Get all the ConfigPropertys

getGUID

public java.lang.String getGUID()

Gets the GUID for this HQ server instance. The GUID is persistent for the duration of an HQ install and is created upon the first call of this method. If for some reason it can't be determined, 'unknown' will be returned.
