The default log level is Error. To change the log level, edit the ProxyService.cong.xml le in one of the
directories listed previously. After the log level is changed, HPWSProxyService must be restarted.
If the log level is set to All, HPWSProxyService creates a second log le called DeviceManager.log.

EnableActiveDeviceDetection (HP WS Pro Proxy Agent 10.4.1 and later)
The default value is true. HPWSProxyService actively checks to detect whether printers are attached to
the PC
. This functionality is new in HP WS Pro Proxy Agent 10.4.1. Earlier versions of HP WS Pro Proxy
Agent use only passive listening for Windows event to detect newly attached printers.
The following is an example of a log message:
[ProcessID:4516, Time:6/27/2016 3:16:09 PM, Message]
OnDevicePresenceCheckEvent() fired
When HP WS Pro Proxy Agent detects a new printer, HPWSProxyService is restarted and the following log
message
s are in the log le:
DetectedDeviceCount = 1 HostedDeviceCount = 0
Detected mismatch in detected device count and Proxy hosted device
count. Restarting proxy...
●
LogDetectedPrinterInfo (HP WS Pro Proxy Agent 10.4.1 and later)
If the value of LogDetectedPrinterInfo is changed to
true, the value of LogLevel must be
changed to All. After the changes are made and HPWSProxyService is restarted, the information about
the USB-connected printer tha
t is received from Windows is logged in the DeviceManager.log le.
The fol
lowing is an example of the log data:
[ProcessID:5136, Time:6/27/2016 5:54:11 PM, Message] USB Printer
Name : HP LaserJet Pro M402-M403 n-dne PCL.6

●
LogLedmAdapterClientIPLogging (HP WS Pro Proxy Agent 10.4.1 and later)
After the value of LogLedmAdapterClientIPLogging is changed to true and HPWSProxyService
is restar
ted, the HPWSProxyLog.log le shows the IP address of the requestor, which is normally
HP Web Jetadmin. LogLedmAdapterClientIPLogging is set to the
o state by default because IP
address resolution might cause a delay on an LEDM adapter that receives a lot of requests.
Due to the nature of various network set ups, the IP address might not reect the true IP address of the
source. F
or example, the address in the log might not be the actual address of the HP Web Jetadmin host.
The following is an example of a message:
[ProcessID:5136, Time:6/27/2016 4:58:16 PM, All] Received request from
the (may not be accurate) IP : 10.20.18.196
UIO test tool
HPWSProxyService uses Universal I/O DLLs (UIO DLLs) to communicate with PC-connected devices over USB. You
can use the UIO test tool to determine if a problem is caused by the UIO DLLs, device, or other proxy
components.
