Metric Descriptions


Metric	Description
Active UNDO Tablespace	The name of the last active undo tablespace of the last period when undo statistics were collected (by default: every 10 minutes)
Begin Time	The beginning of the last period when undo statistics were collected
End Time	The end of the last period when undo statistics were collected
Expired Blocks Removed	Number of expired undo blocks stolen from other undo segments
Expired Blocks Reused	Number of expired undo blocks reused within the same undo segments
Expired Blocks Steals	Number of attempts to steal expired undo blocks from other undo segments
Highest Concurrently TNXs	The highest number of transactions executed concurrently within the specified time range
Longest Query	The length, in seconds, of the longest query executed in the instance during the specified time range
Longest Query SQL ID	SQL identifier of the longest running SQL statement within the specified time range
No Space Error Count	The number of times requests for space in the undo tablespace failed to find any free space available
SnapShot Too Old Error Count	The number of times the error ORA-01555 (snapshot too old) occurred
Transactions	The total number of transactions executed within the specified time range
Unexpired Blocks Removed	Number of unexpired blocks removed from certain undo segments so they can be used by other transactions
Unexpired Blocks Reused	Number of unexpired undo blocks reused by transactions
Unexpired Blocks Steals	Number of attempts to obtain undo space by stealing unexpired extents from other transactions
Used Blocks	The total number of undo blocks consumed

Total Summary

The Total Summary collection collects UNDO definitions, storage and retention.

Metric Descriptions


Metric	Description
Active Undo Tablespace	Name of the last active undo tablespace
Actual Undo Size	The size (in megabytes) of the undo tablespace
Autoextensible	Indicates whether the datafile is autoextensible
Current Retention	Specifies (in seconds) the low threshold value of undo retention
Minimum Required Undo Size	The minimum size (in megabytes) of undo space required. This value takes into account transactions rate, undo generation rate and current undo retention.
Optimal Retention	The optimal undo retention, taking into account undo generation rate and actual undo size
Retention Guarantee	Indicates the state of the Undo tablespace retention (GUARANTEE/NOGUARANTEE) Retention value of GUARANTEE indicates that unexpired undo, in all undo segments in the undo tablespace, should be retained even at the cost of failure of forward-going operations that need to generate undo in those segments.
Transactions Count	The rate of transaction executed within the specified time range
Undo Generated Volume	The rate per second (in megabytes) of undo generated within the specified time range
Undo Management	Indicates whether undo management is automatic or manual

Usability

The Usability collection provides retrieved instance usability based on response time and instance availability.

Metric Descriptions

The percentage of time, within the selected time range, during which the database was available:

•

For a RAC node — the percentage of nodes that are up and running

•

For a single instance — the percentage of the time during this period the instance was up and running

Connect Availability

The percentage of time, within the selected time range, during which the connection to the database instance was successful.

Connection Time

The amount of time it takes to establish a connection.

Last error message that was received upon trying to connect to the database (if an unsuccessful connection trial took place).

Listener Error Message

The last error message (if any) for each listener

The listener name for each listener

Listener Status

For each listener: the percentage of time, within the selected time range, during which the listener was available.

IMPORTANT: Retrieving the Listener Status information requires having an OS user with the permission to run the lsnrctl command.

OS Connect Availability

The percentage of time, within the selected time range, during which the connection to the OS was successful.

OS Error Message

The last error message (if any) received upon an unsuccessful connection trial.

The amount of time (in microseconds) used by the active cursor for carrying out parsing/executing/fetching operations

The date and time when the instance started
