The profile brings 8 checks. Vesana runs the checks over SSH — from a collector in that network or from the Vesana server itself.
| Check | Via | Default thresholds |
|---|---|---|
| Ping | Ping | |
| DNS port (TCP 53) | TCP port | |
| DNS service | SSH | |
| DNS query response | SSH | warn ≥ 200 · crit ≥ 1000 |
| Upstream resolution | SSH | warn ≥ 1 · crit ≥ 2 |
| Zones loaded (BIND) | SSH | |
| CPU | SSH | warn ≥ 80 · crit ≥ 95 |
| Memory | SSH | warn ≥ 85 · crit ≥ 95 |
Thresholds, intervals and checks can be changed per device without touching code. Profile improvements are published as new versions on the hub; existing installations receive them as an update. Profile data as of 2026-08-23.
