Free up disk space
This topic provides an overview and instructions to use the workflow to enable triage and remediation for freeing up disk space on a computer.
Overview
When an event indicating that the disk space on a server has reached the threshold (as defined in the infrastructure policy) appears in TrueSight Presentation Server, operators can launch the Free up disk space orchestration action. This triggers the relevant workflows in TrueSight Orchestration, which verify whether the disk space has crossed the threshold levels and then free up the disk space by deleting certain files on the computer. A post-remediation workflow confirms whether the disk space now adheres to the threshold and sends a notification back to the Presentation Server. Thus, the triage and remediation of event is complete.
By default, TrueSight Orchestration does not create incidents. Incidents are created using TrueSight Operations Management integration with BMC Remedy IT Service Management (ITSM). TrueSight Orchestration only updates incidents during the event orchestration process. Since cleaning up the disk space requires deleting files, by default, a change is created in the ITSM application. Only after a change is approved, the remediation action is performed.
You can automate the process of launching the orchestration action and performing the triage and remediation actions by enabling the Automate Orchestration Action option in the orchestration policy for the Disk Space Full event.
What do I need to get started?
- Add TrueSight Orchestration as a component to integrate with Presentation Server.
- Ensure that the user that you provide to integrate with TrueSight Operations Management is a part of the AoAdmin group in Remedy Single Sign-On.
- Ensure that you have the permission to view and initiate Orchestration actions from events. This permission is governed by the Allow Orchestrator Actions permission on the Administration > Roles page.
(Optional) If you plan to integrate with BMC Remedy IT Service Management, ensure that Presentation Server 11.3.03 is integrated with BMC Service Resolution (BSR) or Proactive Service Resolution (PSR).
Note
The ability to set up and use Proactive Service Resolution will be available with the release of TrueSight Operations Management version 11.3.03.
- (Optional) To automate the event orchestration process for restarting the server, see Managing Orchestration policies.
For more information, see Using Orchestration actions to enable triage and remediation of events.
- Ensure that Event Orchestration runbook is installed on the compatible TrueSight Orchestration Platform.
See Installing the Event Orchestration runbook. Ensure that the following adapters and modules required for this use case are configured and enabled on the TrueSight Orchestration peer.
Is there a way to configure and enable content in one go?
Yes. You can configure and enable the adapters and modules from the installation wizard. After the installation is complete, the adapters and modules are already configured and enabled on the grid. You can only update the configuration if it is required for a use case.
For more information, see Installing the Event Orchestration runbook.
How to free up the disk space?
To free up disk space on a server, you must launch an Orchestration action for a given event in TrueSight Presentation Server.
- On the TrueSight Presentation Server console, go to the Monitoring > Events page.
Click the action menu of the desired event and select Launch Orchestration Actions > Free up disk space.
A status message indicating whether the action initiation was successful is displayed at the top of the page.To view the event orchestration process performed for this action, see the related events.
Related events describe the end-to-end process that starts with initiating triage and ends with the event orchestration completed status.
Where to go next?
You have successfully used the out-of-the-box workflow to delete files to free up disk space. To add orchestration actions for events that match your requirements, see Adding a custom use case to enable Orchestration actions.
