Method Detail

getLatestStats

public List<? extends TimeStampedPojo> getLatestStats(VmRef ref,
                                             long timestamp)

Description copied from interface: VMStatPrintDelegate

Returns statistics gathered by this plug-in newer than the specified time stamp.

Specified by:

getLatestStats in interface VMStatPrintDelegate

Parameters:

ref - - the VM whose statistics to return

timestamp - - the earliest time stamp to return statistics for

Returns:

a list of statistics newer than the time stamp

getHeaders

public List<String> getHeaders(TimeStampedPojo stat)

Description copied from interface: VMStatPrintDelegate

Returns header names for columns this plug-in wishes to add to the vm-stat command.

Specified by:

getHeaders in interface VMStatPrintDelegate

Parameters:

stat - - the first stat returned by VMStatPrintDelegate.getLatestStats(VmRef, long)

Returns:

a list of column headers to append to vm-stat output

getStatRow

public List<String> getStatRow(TimeStampedPojo stat)

Description copied from interface: VMStatPrintDelegate

Returns a row of data for the specified statistic that corresponds to the columns returned by VMStatPrintDelegate.getHeaders(TimeStampedPojo).

Specified by:

getStatRow in interface VMStatPrintDelegate

Parameters:

stat - - the statistic to generate output for

Returns:

a row of text for this statistic separated by column

getOrderValue

public int getOrderValue()

Description copied from interface: Ordered

Defines a value to be used for assigning an order to services. A service with a lower order value will be processed before a service of a higher order value. This ordering is used, for example, to sort views in a client's UI. Please take care to ensure the value returned by this implementation does not collide with other implementations. The order value should be offset from one of the provided constants in this class. Such as Ordered.ORDER_DEFAULT_GROUP.

Specified by:

getOrderValue in interface Ordered

Returns:

the order value
