Data Collection Custom Collection Time

HP Web Jetadmin has a custom collection time feature that allows you to specify the time zone of the devices

you are collecting for and the hour to perform the collection. The data collection start time is 12:00AM local

server time. The default collection time for the Web Jetadmin server can be altered through Tools > Options >

Device Management > Reports > Data Collection Times (see Congure the Data Collection Times for Reports

on page 82). You can specify the time zone and custom hour when setting up data collection (see Add Devices to

Data Collection on page 227) or when creating data collection templates (Create a Data Collection Template

on page 228), For example:

Joy has devices in the Pacic time zone. Her HP Web Jetadmin server is in the mountain time zone. The devices

that Joy manages are not turned on until 8AM. Pacic time. Data collection at 12AM Mountain time would not

capture any data for the devices since they are turned o at the end of the business day. When Joy sets up data

collection for the devices, Joy can specify that she would like the collection to run in the Pacic time zone and at

9:00AM. The data collection would start on the HP Web Jetadmin server at 10AM Mountain time which is 9AM

Pacic time.

HP Web Jetadmin will continue to use a 24 hour data collection cycle for all devices.

Device Utilization by User and Data Collections

The Device Utilization by User data collection type uses SNMP traps to trigger the HP Web Jetadmin host data

collection. Every time a print job is completed by the device, a trap is sent and HP Web Jetadmin runs a complete

query of the device’s job table. Any new entries in the job table are stored in the HP Web Jetadmin database; all

old entries that were previously stored are discarded.

HP Web Jetadmin uses UDP port 27892 as the traps listener port for alerts and any reports that are based on

by-user collections.

Device Utilization by User accuracy may be limited by two things:

●

the device’s ability to store only a limited number of jobs in the job table.

●

the device’s ability to trap when multiple print jobs are queued.

Both of these are dependant on device printer model and rmware. Device Utilization by User and Reporting

should never be used as a substitute for job accounting. HP Web Jetadmin Reports features are designed for

trending and analysis purposes.

NOTE: For devices that don’t support job-traps, HP Web Jetadmin will collect the device’s job table once every

24 hours.

Device and Printer Driver Support for Device Utilization by User

Job logging features are not available on all HP printers. Check your printer documentation to be sure these

device-based features exist.

End of job trapping is not supported on all HP printers. In the case where end of job trapping is not supported,

HP Web Jetadmin will query the job tables once per collection period (24 hours). This may impact the accuracy of

by-user reporting due to the limited size of the device job log.

Windows print drivers supplied by HP are known to support device job log entries. Windows print drivers

available through Microsoft Windows operating systems may not support job log entries. Be sure to use

HP model-specic drivers or the HP Universal Print Driver (UPD) when by-user tracking is required.
