Device Information

The Device section provides several information about the gateway where Kura is running on. This section can be accessed by selecting the Device option located in the System area.


The Profile tab shows several information about the gateway, organized under the Device, Hardware, Software and Java Information.

Device Profile


This tab lists all the bundles installed on Kura, with details about the name, version, id, state and signature status. The signature value will be true if the corresponding bundle is signed, false otherwise.

The buttons in the upper part of the tab allows the user to manage the listed bundles:

  • Start Bundle: starts a bundle that is in Resolved or Installed state;
  • Stop Bundle: stops a bundle that is in Active state;
  • Refresh: reloads the bundles states list.

Device Bundles


The Containers tab lists the containers and images that are currently managed by the Container Orchestration Service. From this tab, the user can start and stop containers and delete images.

Device Bundles


The Threads tab shows a list of the threads that are currently running in the JVM.

A detailed description of this tab is presented in the Command Service page.

System Logs

The System Logs tab allows downloading a compressed file containing all the relevant log files from the gateway. The download button creates and downloads a compressed file with the following items:

  • all the files in /var/log or the content of the folder defined by the property;
  • the content of the journal for the Kura process (kura-journal.log);
  • the content of the journal for the whole system (system-journal.log).

In addition to this feature, the page also allows the real-time displaying of system logs, if the framework has the availability of one or more components that implement the LogProvider API. The UI also provides a useful button to open a new Kura instance in a new browser window. A reference implementation of the LogProvider API is provided in the org.eclipse.kura.log.filesystem.provider bundle. This bundle exposes in the framework a factory that can be used to read filesystem files. By default, Eclipse Kura creates two log providers at startup: one that reads from /var/log/kura.log and the other that reads from /var/log/kura-audit.log.

Device System Logs

The collected logs are stored in a cache server-side and are collected from the point in time where the log providers get attached to the UI (usually, from the login or after a refresh of the browser's window). When the section "System Logs" is accessed, the new log entries are polled from the server's cache and stored client-side.
