Method Details

header

public static ByteBuffer header(String AuthenticatedUser,
 String EffectiveUser,
 String ProcessInfoId)

of

public static ProcessMetricsLoggerCoreV2 of(boolean flushOnLog,
 MultiPartitionWriter writer,
 DateTimeFormatter partitionFormatter)

Initialize a logger for the DbInternal.ProcessMetricsLogCoreV2 table, with log format 1. The returned logger will own a byte array buffer of size 2 MiB (`bufferSize`) when flushOnLog == false, otherwise 1 MiB (`maxEntrySize`).

Parameters:

flushOnLog - if the returned logger should be flushed on every log call

writer - the writer for this logger

partitionFormatter - A datetime formatter for time based partition using the Timestamp column.

Returns:

the logger

log

public void log(byte flags,
 long Timestamp,
 String Name,
 String Interval,
 String Type,
 long N,
 long Sum,
 long Last,
 long Min,
 long Max,
 long Avg,
 long Sum2,
 long Stdev)
         throws IOException

Encodes the data into this logger's buffer. If the remaining size of the buffer after logging is less than 1 MiB (`maxEntrySize`), this logger will be internally flushed.

Parameters:

flags - the flags for this row, which start and end transactions

Timestamp - the Timestamp value, in millis from the epoch

Name - the Name value

Interval - the Interval value

Type - the Type value

N - the N value

Sum - the Sum value

Last - the Last value

Min - the Min value

Max - the Max value

Avg - the Avg value

Sum2 - the Sum2 value

Stdev - the Stdev value

Throws:

IOException

loggerInfo

public static LoggerInfo<ProcessMetricsLoggerCoreV2> loggerInfo()

The basic logger information.

Returns:

the basic logger information

toString

public String toString()

Overrides:

toString in class Object
