  • Constructor Details

    • Stats

      public Stats(StreamInput in) throws IOException
      Throws:
      IOException

    • Stats

      public Stats(long indexCount, long indexTimeInMillis, long indexCurrent, long indexFailedCount, long indexFailedDueToVersionConflictCount, long deleteCount, long deleteTimeInMillis, long deleteCurrent, long noopUpdateCount, boolean isThrottled, long throttleTimeInMillis, long totalIndexingTimeSinceShardStartedInNanos, long totalIndexingExecutionTimeSinceShardStartedInNanos, long totalActiveTimeInNanos, double recentIndexingLoad, double peakIndexingLoad)

  • Method Details

    • add

      public void add(IndexingStats.Stats stats)

    • getIndexCount

      public long getIndexCount()
      The total number of indexing operations

    • getIndexFailedCount

      public long getIndexFailedCount()
      The number of failed indexing operations

    • getIndexFailedDueToVersionConflictCount

      public long getIndexFailedDueToVersionConflictCount()
      The number of indexing operations that failed because of a version conflict (a subset of all index failed operations)

    • getIndexTime

      public TimeValue getIndexTime()
      The total amount of time spend on executing index operations.

    • getIndexCurrent

      public long getIndexCurrent()
      Returns the currently in-flight indexing operations.

    • getDeleteCount

      public long getDeleteCount()
      Returns the number of delete operation executed

    • isThrottled

      public boolean isThrottled()
      Returns if the index is under merge throttling control

    • getThrottleTime

      public TimeValue getThrottleTime()
      Gets the amount of time in a TimeValue that the index has been under merge throttling control

    • getDeleteTime

      public TimeValue getDeleteTime()
      The total amount of time spend on executing delete operations.

    • getDeleteCurrent

      public long getDeleteCurrent()
      Returns the currently in-flight delete operations

    • getNoopUpdateCount

      public long getNoopUpdateCount()

    • getWriteLoad

      public double getWriteLoad()
      Returns a measurement of the write load.

      If this IndexingStats.Stats instance represents a single shard, this is ratio of the sum of the time taken by every index operations since the shard started to the elapsed time since the shard started.

      If this IndexingStats.Stats instance represents multiple shards, this is the average of that ratio for each shard, weighted by the elapsed time for each shard.

    • getRecentWriteLoad

      public double getRecentWriteLoad()
      Returns a measurement of the write load which favours more recent load.

      If this IndexingStats.Stats instance represents a single shard, this is an Exponentially Weighted Moving Rate based on the time taken by indexing operations in this shard since the shard started.

      If this IndexingStats.Stats instance represents multiple shards, this is the average of that ratio for each shard, weighted by the elapsed time for each shard.

    • getPeakWriteLoad

      public double getPeakWriteLoad()
      Returns a measurement of the peak write load.

      If this IndexingStats.Stats instance represents a single shard, this is the highest value that getRecentWriteLoad() would return for any of the instances created for this shard since it started (i.e. the highest value seen by any call to InternalIndexingStats.stats(boolean, long, long, long, long, long, double)).

      If this IndexingStats.Stats instance represents multiple shards, this is the average of that value for each shard, weighted by the elapsed time for each shard. (N.B. This is the average of the peak values, not the peak of the average value.)

    • getTotalActiveTimeInMillis

      public long getTotalActiveTimeInMillis()

    • getTotalIndexingExecutionTimeInMillis

      public long getTotalIndexingExecutionTimeInMillis()
      The total amount of time spend on indexing plus writing indexing buffers.

    • writeTo

      public void writeTo(StreamOutput out) throws IOException
      Description copied from interface: Writeable
      Write this into the StreamOutput.
      Specified by:
      writeTo in interface Writeable
      Throws:
      IOException

    • toXContent

      public XContentBuilder toXContent(XContentBuilder builder, ToXContent.Params params) throws IOException
      Specified by:
      toXContent in interface ToXContent
      Throws:
      IOException

    • equals

      public boolean equals(Object o)
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object
