Constructor Detail

MetricsSource

public MetricsSource(String id)

Constructor used to register the metrics

Parameters:

id - Name of the source this class is monitoring

Method Detail

setAgeOfLastShippedOp

public void setAgeOfLastShippedOp(long timestamp)

Set the age of the last edit that was shipped

Parameters:

timestamp - write time of the edit

refreshAgeOfLastShippedOp

public void refreshAgeOfLastShippedOp()

Convenience method to use the last given timestamp to refresh the age of the last edit. Used when replication fails and need to keep that metric accurate.

setSizeOfLogQueue

public void setSizeOfLogQueue(int size)

Set the size of the log queue

Parameters:

size - the size.

incrLogEditsRead

public void incrLogEditsRead()

Increment the number of log edits read by one.

incrLogEditsFiltered

public void incrLogEditsFiltered(long delta)

Add on the number of log edits filtered

Parameters:

delta - the number filtered.

incrLogEditsFiltered

public void incrLogEditsFiltered()

The number of log edits filtered out.

shipBatch

public void shipBatch(long batchSize,
             int sizeInKB)

Convience method to apply changes to metrics do to shipping a batch of logs.

Parameters:

batchSize - the size of the batch that was shipped to sinks.

incrLogReadInBytes

public void incrLogReadInBytes(long readInBytes)

increase the byte number read by source from log file
