Host Actions Menu¶
Open from host row Actions in the Servers page.

Actions In This Menu¶
- View Details: opens host details drawer.
- Restart Host: queues host reboot flow.
- Configure Auto-Restart: opens restart schedule modal.
- Update Workshop Item: triggers workshop update on this host.
- Install/Uninstall QLFilter: depends on current QLFilter state.
- Re-run Host Setup: re-applies the host configuration playbook on an existing host.
- Delete / Remove: removes host from management (or destroys cloud host).
What QLFilter Is¶
QLFilter is a host-level anti-DDoS filter. It uses eBPF/XDP to drop reflection garbage (DNS, SSDP, and similar noise) at the network driver level before it ever reaches QLDS. One installation covers all instances on the host.
For a full explanation: QLFilter
Operationally:
- Use Install QLFilter on new production hosts.
- Use Uninstall QLFilter only when you intentionally want it removed.
QLFilter Behavior In Menu¶
The QLFilter action changes based on current QLFilter status:
not_installed,error,unknown-> Install QLFilteractive,inactive-> Uninstall QLFilterinstalling,uninstalling-> action shows busy state and is locked
While QLFilter is installing/uninstalling, other host management actions are also blocked.
Update Workshop Item: Practical Use¶
- Open Update Workshop Item from host actions.
- Enter numeric Workshop Item ID.
- Optionally pick running instances for automatic restart after update.
- Submit and monitor instance status.

This is commonly paired with scheduled restart policy: Configure Auto-Restart
Re-run Host Setup¶
Re-run Host Setup re-applies the host configuration playbook to an existing host without reprovisioning it. Use this after a platform update that changes how the host is configured, when a previous setup run failed partway through, or to pick up infrastructure changes on an already-active host.
The action is available when the host status is Active or Error. While it runs, the host enters Configuring status and other management actions are blocked.
Self-hosted hosts — Re-run Host Setup is available but does not modify Redis connectivity (self-host always uses TCP). On cloud and standalone hosts it applies the full setup, including any Redis configuration changes introduced in a platform update.
After the playbook completes, the host returns to Active status.
Running instances are automatically restarted after a successful run. Plan for brief server downtime if you run this on a live host.
