Health Score
The Health Score is a single 0–100 number per server, rolled up across your fleet. It’s built to be honest about what Demerzel actually knows.
Factors and coverage
The score combines several factors — for example Capacity (disk, memory), Updates (pending and security patches) and Availability (service state). Each factor reports both a value and a coverage: how much evidence backs it.
Null is not zero. A factor with no evidence lowers coverage rather than scoring 0. A server Demerzel can’t see clearly is reported as low-coverage, never as falsely healthy.
Bands
| Band | Score | Meaning |
|---|---|---|
| Healthy | 90–100 | Nothing needs attention. |
| Warning | 75–89 | Worth a look soon. |
| Critical | below 75 | Needs attention now. |
The fleet score is coverage-weighted, so a well-observed server counts more than one you’ve barely started monitoring. Open any server to see the full per-factor breakdown.
