An absolute floor
90 % of 4 TB is not a problem, 90 % of 20 GB is. Next to the percentage there is a minimum amount of free space — plus overrides per mountpoint or device.
Warning and critical kept apart — per object, not per server.
Two-level alerting
A single threshold forces a choice between too early and too late. Uptimo separates warning and critical per rule, with minimum duration, recovery time and repeat interval — a value oscillating around the threshold does not produce an alert storm.

What matters here
Per object, not per host
Filesystems, GPUs, sensors and containers alert individually. A full /var never masks a filling /data.
Escalation without noise
A firing warning that reaches critical sends an escalation. The way back stays quiet until recovery.
Six channels
Email, SMS, webhook, Slack, Teams and Telegram — every delivery logged.
Global or per server
Organisation-wide defaults, per-server overrides, or alerting switched off for one host.
