Foundational
Alert Design and On-Call LoadAn alert exists to change what a human does, so any alert that fires without a decision attached is a false alarm regardless of whether its condition was true. GPU fleets generate a specific set of noisy signals that look serious and are not, and separating those from the ones that need a person at three in the morning is what keeps a rotation sustainable. The measure of an alerting system is the fraction of pages that led to an action.🩺 Fleet Reliability & Observability
Core
DCGM and GPU TelemetryNVIDIA's Data Center GPU Manager reads a GPU's counters, runs its diagnostics and exports both to the monitoring stack, and nearly every fleet's dashboards and alerts are built on it. The skill is knowing which of its hundreds of fields carry signal: the profiling metrics that say whether the tensor cores are busy (not the utilization number everyone reads first), the error counters that predict a failure, the throttle reasons that explain a slow step, and the diagnostic levels that decide whether a node returns to the pool. This page walks those fields, derives an MFU estimate from them, and gives a fleet's alert thresholds.🩺 Fleet Reliability & ObservabilitySign in
