1. Collect the data: Specify the devices for which HP Web Jetadmin collects data. The data collection process

causes network trac and requires database space, so you must enable data collection when you want a

report. You can specify which reports HP Web Jetadmin generates based on the type of data collection you

select.

2. Generate the report: Specify the following options:

●

The type of report to generate. The type of data collection specied in step 1 determines which

reports HP Web Jetadmin can generate.

●

The device group or individual devices to include in the report, which might be all of the devices or a

subset of the devices specied in step 1.

NOTE: You can only select devices for which data has been collected.

●

The time frame for the data to be included in the report.

This must be done each time you want the report to run.

Data Collection

Data collections are groups of devices that have specic collection types enabled. You can apply a data collection

type such as Device Utilization to a single device, to multiple devices, or to a device group. When a data collection

is rst applied to a device or devices, HP Web Jetadmin launches a data collection immediately establishing a

data baseline. Once the device is populated under a specic data collection type, data collections occur at some

interval or by way of some trigger.

NOTE: Applying data collection to a device group is done through Group Policies on page 123.

As data is collected, it is stored in tables within the HP Web Jetadmin database. Data retention is set to one year

beyond the initial collection date. This value can be changed in Tools > Options > Shared > Server Maintenance >

Reports (Manage the Report Data on page 52). Data collections for Reports can be retained for up to 5 years.

Data Collection Cycle

Data collection types all have a specic collection cycle that may or may not be dependent on a schedule. The

Device Utilization by User data collections are triggered when printers send job-trap packets into the

HP Web Jetadmin host. All other types are schedule-triggered. All data collections collect data every 24 hours

except for the Hourly Peak Usage data collection which is collected once every hour to provide greater reporting

resolution.

The default start time for the data collection 24 hour cycle is set at 12:00AM at the HP Web Jetadmin host. This

can be congured for each data collection in Tools > Options > Device Management > Reports > Data Collection

Times. When subscribing a device to a data collection, you can choose the time of collection if you prefer a

dierent time. The 24 hour cycle is designed to ensure reporting accuracy. Data within reports will be marked if

the data collected did not represent a full 24 hour cycle.

Initial Data Collection

Activating data collection always launches the specic data collection type on selected devices. This is done to

gather initial or baseline data that is then stored in the database. This is not a user-selectable action. The result

of this initial data collection can be observed in the Results display for any completed data collection.
