System Configuration

class activelogic.Config

This is the resource that governs the system configuration database of an ActiveLogic system.

A configuration value essentially is a key-value pair, where the key serves as a unique identifier. All values are stored as strings in the configuration database, but config_type determines how it should be handled.

All configuration values comes with a default value as well as a min/max range. All these values may differ for different platforms.


Enforcement of min/max range can be disabled by setting _VERIFY_MINMAX to False. This option is reserved for advanced users. Setting out-of-range configuration values may render the system unusable.

Config is a database-bound resource. Thus changes will not take effect until the database transaction is committed.

async Config.list(cls)

Generic list function for all kind of data that belongs to this resource.


cls – Object type that determines what kind of data to get.


A list of given dataclass type.

  • ValueError – Invalid dataclass type.

  • PLDBNewDataCommitted – Conflict with new data committed by an other session.

The following data can be listed from this resource:

  • ConfigValue: Lists all configuration values.

  • ConfigCategory: Lists all configuration categories.

  • ConfigFlags: List all configuration flags.

List may or may not be cached, depending on if cache_enabled is set.

>>> c.list(ConfigValue)
[ConfigValue(key='ALLOW_FWD_ON_INJECT', value=False), ConfigValue(key='ALWAYS_FORWARD', value=True), ...]
>>> c.list(ConfigCategory)
[ConfigCategory(id=1, name='DRDL'), ConfigCategory(id=2, name='Packet Handling'), ...]
>>> c.list(ConfigFlag)
[ConfigFlag(bit=0, name='Restart Engine'), ConfigFlag(bit=1, name='Restart core services'), ...]

The result can be filtered using Python’s list comprehension syntax. For example, to list all changed configuration values:

>>> [v.key for v in c.list(ConfigValue) if v.value != v.default_value]
class activelogic.ConfigType

Defines a set of numeric constants representing available configuration types:

  • INVISIBLE – Invisible configuration that cannot be set.

  • STRING – String value.

  • INTEGER – Integer value.

  • IPADDRESS – IP address represented as a string.

  • FLOAT – Float value.

  • BOOLEANTrue or False

class activelogic.ConfigValue

Object representing a system configuration value.

  • key (str) – Configuration key.

  • value (str, int, float or bool) – Configuration value.

  • config_type (int) – Configuration type. See activelogic.ConfigType.

  • min_value (str, int, float or bool) – Minimum allowed value for the configuration.

  • max_value (str, int, float or bool) – Maximum allowed value for the configuration.

  • default_value (str, int, float or bool) – Default value for the configuration.

  • description (str) – Configuration description.

  • visible (bool) – Configuration visibility. Hidden configurations typically are reserved for advanced usage or debugging.

  • category (int) – Configuration category.

  • flags (int) – Configuration flags. Typically restart options.

  • modified_by (str) – User that made the most recent modification.

  • modification_date (str) – Modification date.

Reading Configurations

async Config.get(key)

Gets the configuration value object for a given key.


key (str) – The configuration key.


The ConfigValue for the given key.

  • ValueError – Config key was not found.

  • PLDBNewDataCommitted – Conflict with new data committed by another session.

async Config.get_value(key)

Gets the configuration value for a given key.


key (str) – The configuration key.


The configuration value for the given key.

Return type

str, int, float or bool


see Config.get().

Updating Configurations

async Config.update(key, value)

Locks the System Configuration resource on the connected system and updates a configuration with the given value.

  • key (str or ConfigValue) – The key or object to update.

  • value (str, int, float or bool) – The new configuration value.

  • KeyError – The config key was not found.

  • TypeError – Value is of incorrect type.

  • ValueError – Numeric value is not within configuration’s min/max range.

  • PLDBError – The current user lacks write permissions on this resource.

  • PLDBError – Resource is locked for writing by another user.

  • PLDBNewDataCommitted – Conflict with new data committed by an other session.


class activelogic.ConfigCategory

Object representing a configuration category.

  • id (int) – Category ID.

  • name (str) – Category name.

class activelogic.ConfigFlag

Object representing a configuration flag.

  • bit (int) – Bit position in ConfigValue’s flags field.

  • name (str) – Flag description.
