Field Detail

connectionStartCount

public final int connectionStartCount

connectionEndCount

public final int connectionEndCount

statementStartCount

public final int statementStartCount

statementEndCount

public final int statementEndCount

sqlStatementStartCount

public final int sqlStatementStartCount

sqlStatementExecuteCount

public final int sqlStatementExecuteCount

sqlStatementEndCount

public final int sqlStatementEndCount

sqlStatementRowFetchCount

public final long sqlStatementRowFetchCount

Cumulative number of rows fetched from SQL statements.

sqlStatementExecuteNanos

public final long sqlStatementExecuteNanos

Cumulative time spent executing SQL statements.

sqlStatementCellRequestCount

public final int sqlStatementCellRequestCount

Total, over all SQL statements that are fetching cells into cache, of the number of requested cells that will be satisfied by those SQL statements. Note that a given SQL statement may round out the predicates and bring back a few more cells than it was asked for.

cellCacheRequestCount

public final int cellCacheRequestCount

cellCacheHitCount

public final int cellCacheHitCount

cellCacheMissCount

public final int cellCacheMissCount

cellCachePendingCount

public final int cellCachePendingCount

executeStartCount

public final int executeStartCount

executeEndCount

public final int executeEndCount

jvmHeapBytesUsed

public final long jvmHeapBytesUsed

jvmHeapBytesCommitted

public final long jvmHeapBytesCommitted

jvmHeapBytesMax

public final long jvmHeapBytesMax

segmentCount

public final int segmentCount

The number of segments currently in cache.

segmentCreateCount

public final int segmentCreateCount

The number of segments that have been created since the server started. (Should equal the sum segmentCreateViaExternalCount + segmentCreateViaRollupCount + segmentCreateViaSqlCount.)

segmentCreateViaExternalCount

public final int segmentCreateViaExternalCount

The number of segments that have been created via external since the server started.

segmentDeleteViaExternalCount

public final int segmentDeleteViaExternalCount

The number of segments that have been deleted via external since the server started.

segmentCreateViaRollupCount

public final int segmentCreateViaRollupCount

The number of segments that have been created via rollup since the server started.

segmentCreateViaSqlCount

public final int segmentCreateViaSqlCount

The number of segments that have been created via SQL since the server started.

cellCount

public final int cellCount

The number of cells currently in cache.

cellCoordinateCount

public final int cellCoordinateCount

The sum of the dimensionality of every cells currently in cache.

For example, each cell in the segment (State={CA, TX} * Year={2011}) has two coordinates.

From this, we can compute the average dimensionality of segments in cache, weighted by the number of cells. It gives an idea of the memory overhead for segment axes.
