DT324 Statistics

Time values are always measured in milliseconds and are usually computed as sys+usr if not stated otherwise (sys+usr is a more reliable indicator than real which can differ substantially due to the way it is measured). The time is accumulated for one event, e.g. menu 12, LOAD MV, LOAD MOD. Time that is spent while executing python code without an active event is not considered.

DI004356 Auto-ID

Key field for table 324

DI004367 Session-ID

A unique ID for each session a user starts. Through this parameter, the performance history messages of a session are bundled. This session ID may differ from the Session ID in DT511.

DI004377 MOD

Only for MI-related events: The ID of the associated module.

DI004378 Event ID

ID of event

Special IDs

• MI ID for MI-related events
• N/A for Py-API timers

DI004383 Event type

Type of event

Values

DI010667 Python Timer ID

Only for Py-API-controlled timers: Python ID.

DI004371 Event (real)

Real, wall-clock time

DI004369 Event (user)

Time the processes initiated by the user spent in a specific event

DI004370 Event (sys)

The time system processes spent in a specific event

DI004380 MTS records created

Number of MTS records created

DI004379 DTP records fetched

Number of DTP records fetched from DB

DI004373 Sent bytes

Number of bytes sent (socket level)

DI004372 Received bytes

Number of bytes received (socket level)

DI057710 Unspecified (real)

[virtual field] Unspecified real time = time spent in modes that could not be determined

This is (entire event real time - db wait time - DTP records selection time).

DI057709 Unspecified (usr+sys)

[virtual field] Unspecified computing time = time spent computing in modes that could not be determined

This is entire (event user time + entire event sys time) - all the time columns to the right of DB wait time.

DI004381 DB wait (real)

Time spent waiting for a reply from the database

DI004385 DTP records selection (real)

Time spent selecting & creating records from database results, without db wait time

DI022749 DTP records selection (sys+usr)

Time spent on DTP records selection (temporary switched to real time in order to include DB wait)

DI022750 MTS records creation

Time spent on MTS records creation

DI022746 Sending raw bytes

Time spent sending raw bytes over socket to client

DI004384 Interfacing functions

Time spent inside Python-DB interfacing functions (both db_select() and db_modify() functions)

DI022747 Py value ranges

Time spent in Py-powered value ranges.

DI022748 Py module macros

Time spent in Py-powered module macros

DI040544 Data serialization

Time spent on data serialization (creation of XML message(s))

DI004387 Module

[virtual field] Exit field for displaying the module title for the MOD field

DI004388 Event MP

[virtual field] Exit field for displaying the menu title for the Event ID field
