Alert rules
Settings → Alert rules manages built-in rules. operator and admin can enable,
disable and edit them.
Catalog
Threshold rules cover GPU temperature, CPU, memory, storage, SMART health and clock skew. Toggle rules cover node, container, BMC, ECC, GPU, network, fabric link, error-log, version-drift and MAC backend conditions. Upgrades add new rules and keep your edits.
Clock skew warns above 30 seconds; sync the master and agents with NTP or chrony.
Fabric Congestion
The default Fabric congestion rule warns while a congestion event is open. It names the node of the associated MangoBoost RNIC, or no node when none is attached. An overlapping RNIC and switch-port event raises one alert. The rule uses the event evaluator; editing a threshold does not change its episode detection. MAC shows alerts in the dashboard; it does not send email or external notifications.
GPU Temperature
| Vendor | Sensor | Warning | Critical |
|---|---|---|---|
| NVIDIA | Core | above 80°C | above 90°C |
| AMD | Junction/hotspot | at or above 95°C | at or above 100°C |
Edit Conditions
Open a rule's edit control. Set an operator and a number for a threshold rule, or a
severity (critical, warning or info) for a toggle rule.
Container Allowlist
When enabled, only containers matching its glob patterns (default mac-*) raise
container alerts.
Export and Reset
Export CSV saves the rules. Reset to defaults restores every built-in rule. If an expected alert is missing, check whether its rule is disabled.
