General Variables

Here are the parameters to configure devices connection and storage system. How parameters are set, read in Wialon Configuration.

Variable Description
ADF_AVL_HW_BIND_ADDR Network interface to listen to devices connections. For example, “ADF_AVL_HW_BIND_ADDR = interface_IP”. Default value is '*', which means 'any interface'.
ADF_AVL_COMM_SERVER Communication server configuration. The format to set the parameter:
<comm-server-name>:<avl-server-host>:<avl-server-port>:<scan-hw_dir>. Default value is '31189'. The parameter scan-hw-dir is optional (by default, its value is '0'). It means enabling autoscanning of new devices types when the system is being initialized.
WIALON_AUTO_CREATE_UNITS If the value is '1', unit which does not exist in the system but sends messages, will be automatically created.
ADF_STORAGE_PATH The path to storage files. Default directory is ./storage (in root directory).
ADF_AVL_UNIT_HISTORY_PERIOD The period to store unit history (in days). Used for database servers only. If not set or the value is '0', unit history is not deleted automatically.
WIALON_DISKSPACE_CHECKER A variable to control free space on the disk with storage. For example, if the variable value is ${ADF_ROOT_PATH}/storage/pd,30G,alert;${ADF_ROOT_PATH}/storage/pd,20G,stop, then when 30GB is left, you will receive an e-mail notification about it, and when 20GB is left, the server will be stopped. By default, the variable is enabled. To disable it, remove it from the configuration file.

IP address can be skipped to listen on all local network interfaces. Default port is 31188. :!: To initialize server part in the trusted mode to any connected user (that is the authorization is not required), the third parameter set as '1' is needed, for example, '31188:*:1'.
