Method Detail

name

public MetricsQueryImpl name(String name)

Specified by:

name in interface MetricsQuery

Parameters:

name - The name of the metrics to query for

See Also:

in {@link Metrics} for a list of names which can be used here.

reporter

public MetricsQuery reporter(String reporter)

Description copied from interface: MetricsQuery

Restrict to data collected by the reported with the given identifier

Specified by:

reporter in interface MetricsQuery

startDate

public MetricsQueryImpl startDate(Date startDate)

Description copied from interface: MetricsQuery

Restrict to data collected after the given date (inclusive)

Specified by:

startDate in interface MetricsQuery

endDate

public MetricsQueryImpl endDate(Date endDate)

Description copied from interface: MetricsQuery

Restrict to data collected before the given date (exclusive)

Specified by:

endDate in interface MetricsQuery

interval

public List<MetricIntervalValue> interval()

Description copied from interface: MetricsQuery

Returns the metrics summed up and aggregated on a time interval. Default interval is 900 (15 minutes). The list size has a maximum of 200 the maximum can be decreased with the MetricsQuery#limit method. Paging is enabled with the help of the offset.

Specified by:

interval in interface MetricsQuery

Returns:

the aggregated metrics

interval

public List<MetricIntervalValue> interval(long interval)

Description copied from interface: MetricsQuery

Returns the metrics summed up and aggregated on a time interval. The size of the interval is given via parameter. The time unit is seconds! The list size has a maximum of 200 the maximum can be decreased with the MetricsQuery#limit method. Paging is enabled with the help of the offset.

Specified by:

interval in interface MetricsQuery

Parameters:

interval - The time interval on which the metrics should be aggregated. The time unit is seconds.

Returns:

the aggregated metrics

sum

public long sum()

Specified by:

sum in interface MetricsQuery

Returns:

the aggregated sum

execute

public Object execute(CommandContext commandContext)

Specified by:

execute in interface Command<Object>

offset

public MetricsQuery offset(int offset)

Description copied from interface: MetricsQuery

Sets the offset of the returned results.

Specified by:

offset in interface MetricsQuery

Parameters:

offset - indicates after which row the result begins

Returns:

the adjusted MetricsQuery

limit

public MetricsQuery limit(int maxResults)

Description copied from interface: MetricsQuery

Sets the limit row count of the result. Can't be set larger than 200, since it is the maximum row count which should be returned.

Specified by:

limit in interface MetricsQuery

Parameters:

maxResults - the new row limit of the result

Returns:

the adjusted MetricsQuery
