> In order to check drill state information, the following tables are to be implemented:
> 1. Memory: a query such as
> select * from sys.drillmemory;
> should return a result set like the following:
> +------------+------------+--------------+------------+------------+
> | drillbit | total_sys_memory |heap_size | direct_alloc_memory |
> +------------+------------+--------------+------------+------------+
> | node1:port1 | 24596676k | 15200420k | 1012372k |
> +------------+------------+--------------+------------+------------+
> | node2:port2 | 24596676k | 15200420k | 2012372k |
> +------------+------------+--------------+------------+------------+
> 2. Threads:
> For each node in a cluster, we need counts of threads of the drillbits. A query like this:
> select * from sys.drillbitthreads;
> should return a result set like the following:
> +------------+------------+--------------+------------+------------+
> | drillbit | pool_name | total_threads | busy_threads |
> +------------+------------+--------------+------------+------------+
> | node1:port1 | pool1 | 8 | 2 |
> +------------+------------+--------------+------------+------------+
> | node2:port2 | pool2 | 10 | 5 |
> +------------+------------+--------------+------------+------------+
