setHistoryEntriesForAttribute

void setHistoryEntriesForAttribute(String pMBean,
                                   String pAttribute,
                                   String pPath,
                                   String pTarget,
                                   int pMaxEntries)
                            throws MalformedObjectNameException

Deprecated. use setHistoryLimitForAttribute(java.lang.String, java.lang.String, java.lang.String, java.lang.String, int, long) instead

Switch on history tracking for a specific attribute. If pMaxEntries is 0 history tracking is switched off.

Parameters:

pMBean - MBean object name

pAttribute - attribute name

pPath - inner path (optional)

pTarget - remote target or null for a local mbean

pMaxEntries - max last entries to remember, if 0 history tracking is switched off.

Throws:

MalformedObjectNameException - if the given name is not proper object name

setHistoryLimitForAttribute

void setHistoryLimitForAttribute(String pMBean,
                                 String pAttribute,
                                 String pPath,
                                 String pTarget,
                                 int pMaxEntries,
                                 long pMaxDuration)
                          throws MalformedObjectNameException

Switch on history tracking for a specific attribute. If pMaxEntries and pMaxDuration is 0 then history tracking is switched off. If either pMaxEntries or pMaxDuration 0, then the given limit applies. If both are != 0, then both limits are applied simultaneously.

Parameters:

pMBean - MBean object name

pAttribute - attribute name

pPath - inner path (optional)

pTarget - remote target or null for a local mbean

pMaxEntries - max last entries to remember, if 0 history tracking is switched off.

pMaxDuration - maximum duration the maximum duration for how long to keep a value (in seconds)

Throws:

MalformedObjectNameException - if the given name is not proper object name

setHistoryEntriesForOperation

void setHistoryEntriesForOperation(String pMBean,
                                   String pOperation,
                                   String pTarget,
                                   int pMaxEntries)
                            throws MalformedObjectNameException

Deprecated. use setHistoryLimitForOperation(java.lang.String, java.lang.String, java.lang.String, int, long) instead

Switch on history tracking for an operation. If pMaxEntries is 0 history tracking is switched off. The return value of the operation will be tracked.

Parameters:

pMBean - MBean object name

pOperation - operation to track

pTarget - remote target or null for a loal mbean

pMaxEntries - max last entries to remember, if 0 history tracking is switched off.

Throws:

MalformedObjectNameException

setHistoryLimitForOperation

void setHistoryLimitForOperation(String pMBean,
                                 String pOperation,
                                 String pTarget,
                                 int pMaxEntries,
                                 long pMaxDuration)
                          throws MalformedObjectNameException

Switch on history tracking for an operation. If pMaxEntries and pMaxDuration is 0 history tracking is switched off. The return value of the operation will be tracked. If either pMaxEntries or pMaxDuration 0, then the given limit applies. If both are != 0, then both limits are applied simultaneously.

Parameters:

pMBean - MBean object name

pOperation - operation to track

pTarget - remote target or null for a loal mbean

pMaxEntries - max last entries to remember, if 0 history tracking is switched off.

pMaxDuration - maximum duration the maximum duration for how long to keep a value (in seconds)

Throws:

MalformedObjectNameException

resetHistoryEntries

void resetHistoryEntries()

Remove all history entries and switch off history tracking globally.

debugInfo

String debugInfo()

Get latest debug information if debugging is switched on. The returned output will not take more than getMaxDebugEntries() lines.

Returns:

debug info in plain ascii.

resetDebugInfo

void resetDebugInfo()

Reset all debug information stored internally

getHistorySize

int getHistorySize()
            throws IOException

Get the size in bytes which the history mechanism requires in total if serialized.

Returns:

size of the complete history in bytes

Throws:

IOException - if serialization (which is required for the size determination) fails.

getHistoryMaxEntries

int getHistoryMaxEntries()
