Preview features¶
Not everything in Vesana is stable yet. Areas still under active development are switched off by default on every instance — completely: no menu entry, no page, no API. They only exist once you enable them in the admin area.
You find the switch under Admin → System → Preview features (super admins only).
What is preview?¶
| Area | What it does | When off |
|---|---|---|
| Policies | Rule-based automation: assign tags, add checks, adjust configuration for every host matching a condition (docs) | Page and API are locked, the policy sync does not touch any host |
| Reports (PDF + SLA) | Scheduled PDF reports by e-mail and SLA evaluations (PDF, SLA) | No report is generated or sent |
| Status Pages | Public status pages at /status/<slug> (docs) |
The public links answer 404 as well |
| Anomaly Detection & Predictions | Z-score anomalies and capacity predictions on host detail pages and as dashboard widgets | Nothing is computed |
Each area has its own switch. A switch takes effect immediately, without a restart — for every user of the instance.
What "off" means exactly¶
- The menu entry is missing, for super admins too. A direct link ends up on the start page.
- The API answers with 404 (
PREVIEW_FEATURE_DISABLED) — not 403. The area simply does not exist on this instance. - The related background jobs pause.
- Data you already created is kept. Policies, report schedules and status pages are back the moment you switch the area on, exactly as you left them.
What happens on update¶
Anyone who was already using one of these areas before updating to v1.9.445 (created policies, report schedules or status pages) keeps it enabled — nothing disappears without a word. Fresh installations start with everything off. Anomaly detection was off by default before; its switch merely moved here (the old "Anomaly Detection" tab redirects).
In the portal layout the affected menu entries carry a Preview badge. As long as an area is off there is no visibility switch for it — it is not there in the first place.
Why so strict?¶
An area that is only missing from the menu but still reachable via URL or API would be cosmetics. Whoever uses a preview should do so deliberately — and report back via the feedback button. Once an area is stable, its switch disappears and it is simply there.
