Process Element Performance

To optimize the performance of your processes and process elements you can use process element performance statistics to analyze the performance of the engine. This allows you to detect long-running and performance-intensive process elements and processes which you then can optimize.

Engine Cockpit

You can activate and analyze the results of the performance statistics in the Performance view of the Engine Cockpit.

CSV Statistics File

It is possible to configure Axon Ivy Engine to print out performance statistics information periodically into a CSV formatted file. The file contains detailed information for each process element executed since the last dump.

After activation, all performance-related information is collected and written to the log directory of your Axon Ivy Engine installation. The file name has the pattern performance_statistic_yyyy-mm-dd_hh-mm-ss.csv (e.g., performance_statistic_2011-03-15_09-21-05.csv)

Process element performance statistics are not collected by default. They need to be enabled in the ProcessEngine section of the ivy.yaml file.


Time values are in milliseconds. The execution of most process elements gets divided into two categories, internal and external.

Internal Category

The internal category is used for the execution time in the process engine itself, without the external execution time.

External Category

The external category is used for execution time in external systems. In the table below, the process elements that use the external category are listed.

Process Element

Internal Category

External Category

Database Step

Parameter-mapping, caching, output-mapping, and IvyScript execution.

The execution of the SQL statement on the database server.

Web Service Call Step

Parameter-mapping, caching, output-mapping, and IvyScript execution.

The execution of the Web Service on the web server.

E-Mail Step


The interaction with the Mail-Server.

Program Interface

The execution of the defined Java-Class.

An entry in the view is created for each executed process element. The table below shows what information is available.



Entry ID

Entry ID. Useful to order the entries by their first execution.


Application of the process element.

Process Model

PM Version

Process Model Version of the process element.

Process Path

The path to the process.

Element ID

The identifier of the process element.

Element Name

The first line of the process element name (display name).

Element Type

The type of the process element.

Total Time

Total time [ms] of internal and external execution.

Int. Executions

Total internal executions of the process element.

Total Int. Time
