Kernel Reader Data Hierarchy

Table A-1 lists the Kernel Reader data hierarchy. The first column identifies whether the parameter is a node (N) or a property (P). A node in the hierarchy is a starting point for a branch of the hierarchy, similar to the point where a branch meets the trunk of a tree. All properties that belong to a node appear below the node and are marked with a P. For example, the cpu.busy and cpu.user properties fall under the cpu node.

The second column contains the name of the node or property.

The third column contains two values. The first value is a two-prong value set off in parentheses, such as (R.f). This value identifies the type of value and the data type.

Solstice SyMON generates five types of values:

• (I) Instant value at the sample time
• (S) Summary over the last sample or report interval
• (A) Average value over last sample or report interval
• (%) Percentage value as float (100.0 == 100%) over the last sample or report interval
• (R) Rate (per second) value over the last sample or report interval

Note that there is no value type or data type for nodes. Data types include f (float), i (integer), and s (string [text]).

The second value in the third column is a brief description of the node or property.
