Friends of Eclipse,
Eclipse is an open source community that benefits millions of developers around the world each and every day! During the month of September, we are asking you to give back to our wonderful open source community. All donations will be used to improve Eclipse technology. Your contribution counts!
We thank you for this gesture, and for giving back to our community.
The Usage Data Collector (UDC) collects information about how individuals are using the Eclipse platform. This information is periodically uploaded to servers hosted by The Eclipse Foundation. The intent is to use this data to help committers and organizations better understand how developers are using Eclipse.
The UDC is designed to have a minimal impact on user experience. The impact on performance is negligible.
Once installed, the UDC immediately starts monitoring your use of Eclipse. In particular, it takes note of the views, editors, perspectives, and commands that you use. It also keeps track of when you bring the Eclipse workbench window into focus. At a lower level, the UDC records the bundles (plug-ins) that are loaded by Eclipse. The information collected amounts to the id of the entity (view, editor, perspective, etc.), the symbolic name and version of the bundle that contains the entity, and the time of the event.
We recognize that the data collected may contain sensitive information. Symbolic names for bundles can potentially include company and product names; bundle versions, as well as view, editor, and perspective ids could potentially also contain sensitive information. With this in mind, the UDC includes a filtering framework that can be used to restrict the type of information that is uploaded.
After a configurable period of time (defaults to five days) passes, the UDC asks you for permission to upload.
At this point, you can tell the UDC what you want to do:
The period of time between requests to upload the usage data can be configured by changing the "Upload Period" field on the "Usage Data Collection | Uploading" preferences page.
The target for uploads is a server hosted by The Eclipse Foundation. The data is stored in its collected form in a foundation database.
Two different keys are used to identify the source of the uploaded data. The first key identifies the workstation; this key is stored locally in your "user home" directory. The second key identifies the workspace; this key is stored in the ./.metadata/.plugins/org.eclipse.epp.usagedata.recording directory for the workspace. These keys are uploaded along with the usage data.
