counters table provides running totals of
events such as reads and writes for specific kernel blocks and
data nodes. Counts are kept from the most recent node start or
restart; a node start or restart resets all counters on that
node. Not all kernel blocks have all types of counters.
The following table provides information about the columns in
counters table. For each column, the
table shows the name, data type, and a brief description.
Additional information can be found in the notes following the
