HP Device Discovery: Enhance Your Network Management with Web Jetadmin Software

<property name="NumDiscoveryLogs"> <type>HP.Imaging.Wjp.Sdk.Core.Framework.ConfigurationItemString </type>

<value>2</value>

</property>

This property is useful when PC-connected device discoveries are performed over a long period of time. The default setting causes HP Web Jetadmin to overwrite a second log file for each new discovery.

5.To increase the number of log files that HP Web Jetadmin creates, change the <value> entry to the required number of log files.

6.Close and save the DiscoveryManager.config.xml file.

7.Restart the HP Web Jetadmin service (HPWJA Service). For instructions, see Restart the HP Web Jetadmin Service Manually on page 21.

CAUTION: Be careful when restarting the HP Web Jetadmin service. Conflicts with existing operations, such as firmware upgrades, alerts, and data collection, might occur.

Each time HP Web Jetadmin contacts an address to determine if a PC-connected device is present, HP Web Jetadmin adds an entry to the log files in the following directory:

C:\Windows\ServiceProfiles\NetworkService\AppData\Local\Hewlett-Packard\HPWebJetadmin\WjaService \config\FileStore\Discovery\Specified

The following are examples of log entries:

●An SNMP error occurred when trying to contact remote server

An SNMP-related error occurred.

●An SNMP Credentials error has occurred

SNMP credentials are required for the device.

●An SNMP Timeout error has occurred

SNMP did not respond within the specified HP Web Jetadmin timeout settings. For more information about the SNMP timeout settings, see Configure the SNMP Settings on page 39.

●The remote server machine does not exist or is unavailable

The remote host does not qualify as a PC-connected host.

●A Timeout occurred trying to contact Remote Host

A timeout occurred while trying to start a WMI session with the host.

●The Remote host could not be contacted

A WMI session could not be started.

●Access is denied

The remote host denied access to a WMI session.

Quick Device Discovery

If you know the IP address or hostname of a network-connected device, you can use the Quick Device Discovery feature to find the device instead of running a full network discovery. To use the IP hostname for the Quick Device Discovery feature, DNS lookups must be enabled. For instructions on enabling DNS lookups, see Configure the DNS Settings on page 40.
