Configure the Device Monitoring¶

PLOSSYS 5 is able to monitor the physical statuses of devices via IPP. For this, the device has to have an IPP interface.

The IPP data requested from the device is stored in the database object physical and will be overwritten whenever the device is checked.

In PLOSSYS Administrator, the device status can be displayed in an extra column and can be updated manually via menu item. The details of the device status are displayed in an extra dialog.

By default, the device monitoring is deactivated (NEVER). The status of the device can be checked after specific actions, for example, after printing a job (AFTER_PRINT).

Activate the Device Monitoring¶

For activating the monitoring for all devices, set the PRINTER_MONITOR_MODE service key to the action when the devices are to be checked.

For activating the monitoring for a specific device, set the monitorMode printer key to the action when the specific device is to be checked.

Relevant Keys¶

The following printer keys are relevant for the device monitoring:

connection: URL of the printer connection
monitorConnection: IPP URL of the device for monitoring its status
monitorMode: If and when the status is checked for the specific device

The following service key is relevant for the device monitoring:

PRINTER_MONITOR_MODE: If and when the devices' statuses are checked; this value is overwritten by the printer-specific monitorMode printer key.

Evaluation of the IPP URL¶

The IPP URL required for the device monitoring is evaluated in the following steps:

If the monitorConnection printer key is specified, this IPP URL is used for monitoring the status.
Otherwise, it is checked if the connection printer key contains an IPP URL. If yes, this IPP URL is used for monitoring the status.
If the connection printer key does not contain an IPP URL, the following modifications of connection are tried. If one of these modifications can be used for the device monitoring, the value is saved as monitorConnection:
- http://<connection_server_name>:631
- https://<connection_server_name>:443
- https://<connection_server_name>:631
- http://<connection_server_name>:631/ipp
- https://<connection_server_name>:443/ipp
- https://<connection_server_name>:631/ipp
- http://<connection_server_name>:631/ipp/printer
- https://<connection_server_name>:443/ipp/printer
- https://<connection_server_name>:631/ipp/printer
If no IPP URL can be evaluated for the specific device, the monitoring for this device is disabled, that means the monitorMode printer key is set no NEVER.
