getAvailableValueMetrics

public Set<ValueMetric> getAvailableValueMetrics()

Description copied from interface: RepositoryMonitor

Get the ValueMetric enumerations that are available for use by the caller with RepositoryMonitor.getHistory(ValueMetric, Window).

Specified by:

getAvailableValueMetrics in interface RepositoryMonitor

Returns:

the immutable set of ValueMetric instances; never null but possibly empty if the caller has no permissions to see any value metrics

See Also:

RepositoryMonitor.getHistory(ValueMetric, Window)

getAvailableDurationMetrics

public Set<DurationMetric> getAvailableDurationMetrics()

Description copied from interface: RepositoryMonitor

Get the DurationMetric enumerations that are available for use by the caller with RepositoryMonitor.getHistory(DurationMetric, Window).

Specified by:

getAvailableDurationMetrics in interface RepositoryMonitor

Returns:

the immutable set of DurationMetric instances; never null but possibly empty if the caller has no permissions to see any duration metrics

RepositoryMonitor.getHistory(DurationMetric, Window), RepositoryMonitor.getLongestRunning(DurationMetric)

getAvailableWindows

public Set<Window> getAvailableWindows()

Description copied from interface: RepositoryMonitor

Get the Window enumerations that are available for use by the caller with RepositoryMonitor.getHistory(DurationMetric, Window) and RepositoryMonitor.getHistory(ValueMetric, Window).

Specified by:

getAvailableWindows in interface RepositoryMonitor

Returns:

the immutable set of DurationMetric instances; never null but possibly empty if the caller has no permissions to see any windows

See Also:

RepositoryMonitor.getHistory(DurationMetric, Window), RepositoryMonitor.getHistory(ValueMetric, Window)

getHistory

public History getHistory(ValueMetric metric,
                          Window windowInTime)
                   throws AccessDeniedException

Description copied from interface: RepositoryMonitor

Get the statics for the specified value metric during the given window in time. The oldest statistics will be first, while the newest statistics will be last.

Specified by:

getHistory in interface RepositoryMonitor

Parameters:

metric - the value metric; may not be null

windowInTime - the window specifying which statistics are to be returned; may not be null

Returns:

the history of the metrics; never null but possibly empty if there are no statistics being captures for this repository

Throws:

AccessDeniedException - if the session does not have privileges to monitor the repository

RepositoryMonitor.getAvailableValueMetrics(), RepositoryMonitor.getAvailableWindows()

getHistory

public History getHistory(DurationMetric metric,
                          Window windowInTime)
                   throws AccessDeniedException

Description copied from interface: RepositoryMonitor

Get the statics for the specified duration metric during the given window in time. The oldest statistics will be first, while the newest statistics will be last.

Specified by:

getHistory in interface RepositoryMonitor

Parameters:

metric - the duration metric; may not be null

windowInTime - the window specifying which statistics are to be returned; may not be null

Returns:

the history of the metrics; never null but possibly empty if there are no statistics being captures for this repository

Throws:

AccessDeniedException - if the session does not have privileges to monitor the repository

getLongestRunning

public DurationActivity[] getLongestRunning(DurationMetric metric)
                                     throws AccessDeniedException

Description copied from interface: RepositoryMonitor

Get the longest-running activities recorded for the specified metric. The results contain the duration records in order of increasing duration, with the activity with the longest duration appearing last in the array.

Specified by:

getLongestRunning in interface RepositoryMonitor

Parameters:

metric - the duration metric; may not be null

Returns:

the activities with the longest durations; never null but possibly empty if no such activities were performed

Throws:

AccessDeniedException - if the session does not have privileges to monitor the repository
