Availability and uptime tracking
While outages are something you report, availability is recorded automatically. Whenever a monitored device or server goes offline and comes back, JOATOS logs the window — so you can see real downtime and uptime percentages without lifting a finger.
The Availability tab
On the Status page, open the Availability tab. It has two parts:
- Currently Offline — anything down right now, each row showing the entity, its site, type, and a live "Offline for Xh Ym" counter.
- Outage History — closed downtime windows, newest first, each showing the entity, how long it was down for, a Resolved badge, and how long ago it recovered. Use Load more to page through.
Filter both by All types, Devices, Servers, Services, or Monitors.
How it's tracked
Each time an entity goes offline, JOATOS opens an availability record with the offline time; when it recovers, it stamps the online time and computes the duration. This runs off the same monitoring that powers status — you don't configure anything.
Uptime percentage
JOATOS can calculate an uptime % for an entity over a date range (downtime versus total time in the period). This underpins availability reporting and per-entity uptime figures.
Uptime is measured over what was actually monitored
An uptime percentage is calculated over the period JOATOS was actually watching, not the whole window you asked for. A device added three days ago, viewed over 60 days, reads "monitored 3d of 60d" rather than claiming a perfect 60-day record.
Where nothing was observed at all, you'll see Not monitored instead of a number. That's deliberate: a newly added device has no uptime history, and reporting 100% would be a lie that looks like good news.
Notes & tips
- Availability covers devices, servers, services and uptime monitors. A service counts as down when it's degraded, not only when it's fully out. For external websites, see Uptime Monitoring.
- A long-running Currently Offline entry is your cue to investigate — select it to jump to the device or server.
