setLogChannelInterfaceFactory

public static void setLogChannelInterfaceFactory(LogChannelInterfaceFactory logChannelInterfaceFactory)

replaceLogCleaner

public void replaceLogCleaner(int maxLogTimeoutMinutes)

init

public static void init(int maxSize,
                        int maxLogTimeoutMinutes,
                        boolean redirectStdOut,
                        boolean redirectStdErr)

Initialize the central log store with optional limitation to the size and redirect of stdout and stderr

Parameters:

maxSize - the maximum size

maxLogTimeoutMinutes - the maximum time that a log line times out in hours

redirectStdOut - a boolean indicating whether to redirect stdout to the logging framework

redirectStdErr - a boolean indicating whether to redirect stderr to the logging framework

init

public static void init(int maxSize,
                        int maxLogTimeoutMinutes)

Initialize the central log store with optional limitation to the size

Parameters:

maxSize - the maximum size

maxLogTimeoutMinutes - The maximum time that a log line times out in hours.

init

public static void init()

init

public static void init(boolean redirectStdOut,
                        boolean redirectStdErr)

Initialize the central log store with arguments specifying whether to redirect of stdout and stderr

Parameters:

redirectStdOut - a boolean indicating whether to redirect stdout to the logging framework

redirectStdErr - a boolean indicating whether to redirect stderr to the logging framework

getInstance

public static KettleLogStore getInstance()

getLastBufferLineNr

public static int getLastBufferLineNr()

Returns:

the number (sequence, 1..N) of the last log line. If no records are present in the buffer, 0 is returned.

getLogBufferFromTo

public static List<KettleLoggingEvent> getLogBufferFromTo(String parentLogChannelId,

Get all the log lines pertaining to the specified parent log channel id (including all children)

Parameters:

parentLogChannelId - the parent log channel ID to grab

includeGeneral - include general log lines

from -

to -

Returns:

the log lines found

getLogBufferFromTo

public static List<KettleLoggingEvent> getLogBufferFromTo(List<String> channelId,
