        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

        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.

      • 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.

      • stack

        public final String stack
        A printout of the stack trace which represents the code stack when the event was created. Useful for debugging purposes and identifying orphaned connections and statements.
