public class ServerStats
extends java.lang.Object

ServerStats This class is used to log server events to a file, in Server Statistics files. It can track counts (how many times something was done) and average elapsed times. File writing is controlled by the logging.properties file settings. User-defined events can be added using addServerStatsEvent.

Constructor Detail

ServerStats

public ServerStats()

Method Detail

addServerStatsEvent

public static int addServerStatsEvent(java.lang.String name)

Register an event type. Use the returned int for subsequent calls to the "log" methods. The returned int will always be greater than zero.

Parameters:

name - The name that you want to appear in the server stats file.

Returns:

The index which is used in subsequent calls to logEvent and logTimedEvent.

getCount

public static long getCount(int eventType)

Get the current event count for the specified event type.

Parameters:

eventType - The index of the event

Returns:

count for the specified event

getCurrentStats

public static java.util.Map getCurrentStats(boolean resetCounters)

Gets a hash map of the top-level entries in current (in-memory) statistics. For internal Factory use only.

getKeyIntValue

public static int getKeyIntValue(java.lang.String key)

Gets the int value corresponding to an event name.

Parameters:

key - The name as shown in the server stats file.

Returns:

The integer value for this event (for use in logEvent).

getName

public static java.lang.String getName(int index)

Gets the name corresponding to an event index.

Parameters:

index - The integer index for an event.

Returns:

The name as shown in the server stats file.

getServerStatsLog

public static com.bowstreet.appserver.logmanager.ServerStatsLog getServerStatsLog(boolean resetCounters)

Gets all the current values in format suitable for writing to file. For internal Factory use only.

getStatsAttributes

public static java.lang.String[] getStatsAttributes()

isRunModelOnly

public static boolean isRunModelOnly(int index)

See if an entry is obsolete RunModel

logEvent

public static void logEvent(int eventType)

Increment the counter for an event.

Parameters:

eventType - The index of the event. This can be a predefined event or a user-defined event returned from addServerStatsEvent.

Example:

logEvent(ServerStats.STAT_Regens);

logTimedEvent

public static void logTimedEvent(int eventType,
                                 long elapsed)

Log a single action, with its elapsed clock time.

Parameters:

eventType - The index of the event. This can be a predefined event or a user-defined event returned from addServerStatsEvent.

elapsed - The time for this event.

logTimedEvent

public static void logTimedEvent(int eventType,
                                 long elapsed,
                                 java.lang.String name,
                                 java.lang.String childName)

Log action, with name, sub-name and an elapsed time. See server stats doc for how this is used for model requests, for example.

Parameters:

eventType - The index of the event. This can be a predefined event or a user-defined event returned from addServerStatsEvent.

Example:

ServerStats.logTimedEvent(ServerStats.STAT_ModelRequest, elapsed, modelID, pageID);

setEntry

public static void setEntry(int eventType,
                            long value)

Set the count of an event type to a specific value.

Parameters:

eventType - The index of the event.

value - the value that this event entry be set to.
