HP Systems Insight Manager - Manual (Page 309)

Job logging is enabled by default. The schedulable attribute
specifies whether the tool can be run as a scheduled task. When
schedulable="false" the tool can only run as a "run now" task.
Tools are schedulable by default. The guid attribute specifies a
globally unique identifier (GUID) for the tool. Because the
system generates a GUID for a tool during the add operation, this
field should only be specified during a modify operation. -->
