Select Delete/Drop to delete the registration of the selected Ark console. Please note that deleting a console registration does not remove the console from the backing database. PEM will confirm that you wish to delete the registration before removing it.
Select Download console logs to download the log files from the selected console.
Select Installation options to open the Installation options dialog and review or modify console deployment properties.
Select Disconnect Server to disconnect from the selected Ark console.

Use options on the console Dashboard panel or context menu to download a zip file that contains the server logs for the underlying application server. You can use the log file to confirm changes to server status or verify server activity. To download a console log you can either:
Highlight a console name in the tree control and navigate to the Dashboard tab; then, select the Download console logs option from the Quick Links panel.
You can also review the console logs via an ssh session. Log files are stored in /var/log/edb-ark; the current log file is /var/log/edb-ark/ark.log. Use the Linux tail utility to display the most recent entries in any of the server logs. For example, to review the last 10 lines in the server log file, use SSH to connect to the console host's backing database and enter:
tail file_name
Where file_name specifies the complete path to the log file. Include the -F option to instruct the tail utility to display only the last 10 lines of the log file, and new log file entries as they are added to the file:
tail -F file_name
The Installation options dialog displays the deployment properties of the selected console. To open the dialog, right-click on a console name and select Installation options from the context menu.
