The iTools script provides a command-line interface to interact with PowSyBl, available under Linux and Windows (MacOS is not supported yet).

An iTools package is constituted of:

  • a bin directory containing the executable scripts and the binaries
  • an etc directory containing the configuration and the XIIDM schemas
  • a lib directory containing C++ libraries
  • a share/java directory containing Java libraries


The iTools script is available in the bin directory.

$> ./bin/itools
usage: itools [OPTIONS] COMMAND [ARGS]

Available options are:
    --config-name <CONFIG_NAME>   Override configuration file name

Available commands are:

Use this option to overload the default base name for the configuration file. It overrides the powsybl_config_name property defined in the itools.conf file.


The iTools script reads its configuration from the <ITOOLS_PREFIX>/etc/itools.conf property file. The properties defined in this file are used to configure the Java Virtual Machine.

Example of itools.conf file:

# PowSyBl configuration directories

# PowSyBl configuration base name

# Maximum size of the Java memory allocation pool

powsybl_config_dirs: This is an optional property that defines the list of the folders where the configuration files are located. If this property is not set, the configuration files are read from <USER_HOME>/.itools and <ITOOLS_PREFIX>/etc folders. Note that the order of the folder is really import as the PowSyBl configuration is stackable.

powsybl_config_name: This is an optional property that defines the base name of the configuration files. The default value for this property is config.

java_xmx: This is an optional property that defines the maximum size of the memory allocation pool of the JVM. The default value for this property is 8 gigabytes.

The list of the deprecated properties is available here


The iTools script uses logback as logging framework. To configure the logging framework, edit the <ITOOLS_HOME>/etc/logback-itools.xml configuration file. Please refer to the logback manual for the available logging options.

Sometimes, it could be useful for a user to have its own logging configuration to filter unexpected logs or to have more details for some features. The simplest way to proceed is to copy the global configuration file in the <USER_HOME>/.itools folder and then customize it.

Example of logback-itools.xml:

<?xml version="1.0" encoding="UTF-8"?>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
            <Pattern>%d{yyyy-MM-dd_HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern>
    <root level="ERROR">
        <appender-ref ref="STDOUT" />

Available commands

The iTools script relies on a plugin mechanism: the commands are discovered at runtime and depend on the jars present in the share/java folder.
