Instance_Stats	sga_buffer_cache_size	Number	The total size of the buffer cache for the database instance, in bytes.
Instance_Stats	sga_buffer_hit_limit	Number	The maximum number of number of buffers that can be hit in the database instance without finding a free buffer.
Instance_Stats	sga_data_dict_hit_ratio	Number	The hit-to-miss ratio for the database instance's data dictionary.
Instance_Stats	sga_fixed_area_size	Number	The size of the fixed area (also referred to as the fixed SGA) for the database instance, in bytes.

Instance_Stats	tablespace_used	String	The total amount of tablespace used for the database instance, in bytes.
Session_Info	buffer_cache_hit_ratio	Number	The percentage of logical reads from the buffer during the session (1-physical reads/session logical reads*100).
Session_Info	commits	Number	The number of commits per second performed by the user associated with the session.
Session_Info	cpu_used	Number	The number of CPU centiseconds used by the session. Divide this value by 100 to get the CPU seconds.
Session_Info	cursor	Number	The number of the cursor currently in use by the session.
Session_Info	elapsed_time	Number	The total amount of time elapsed since the user started the session by logging into the database server, in seconds.
Session_Info	logical_reads	Number	The total number of consistent gets and database block gets performed during the session.
Session_Info	machine	String	The name of the logical host associated with the database instance.
Session_Info	memory_sorts	Number	The total number of memory sorts performed during the session.
Session_Info	physical_reads	Number	The total number of physical reads performed during the session.
Session_Info	seconds_in_wait	Number	The description of seconds_in_wait depends on the value of wait_time. If wait_time = 0, seconds_in_wait is the number of seconds spent in the current wait condition. If wait_time has a nonzero value, seconds_in_wait is the number of seconds that have elapsed since the start of the last wait. You can get the active seconds that have elapsed since the last wait ended by calculating seconds_in_wait - wait_time / 100.
Session_Info	session_id	String	The unique id that identifies the session.
Session_Info	session_status	String	The current status of the session.	Online, Offline.
Session_Info	table_scans	Number	Number of table scans performed during the session.
Session_Info	user	String	Name of the database process user.
Session_Info	wait_state	String	Provides the current wait state for the session. Can indicate that the session is currently waiting or provide information about the session's last wait.	WAITING (the session is currently waiting), WAITED UNKNOWN TIME (the duration of the last session wait is unknown), WAITED SHORT TIME (the last session wait was < 1/100th of a second), WAITED KNOWN TIME (the wait_time is the duration of the last session wait).
Session_Info	wait_time	Number	When wait_time = 0, the session is waiting. When wait_time has a nonzero value, it is displaying the last wait time for the session.
Lock_Info	last_call_minute	Number	Represents the amount of time elapsed since the session_status changed to its current status. The definition of this field depends on the session_status value. If session_status = ONLINE, the last_call_minute value represents the time elapsed since the session became active. If session_status = OFFLINE, the last_call_minute value represents the time elapsed since the session became inactive.
Lock_Info	lock_mode	String	The mode of the lock on the object.
Lock_Info	lock_session_id	String	The session identifier of the locked object.
