Linux CPU Monitor

This tool provides Linux CPU visibility through a lightweight, script-friendly interface. It reports per-core and total CPU usage, 1/5/15 minute load averages, and threshold-based signals to guide capacity planning and incident response for admins, DevOps teams, and SREs across bare-metal, virtualized, and containerized environments.\n\nConceptually, it reads procfs counters from /proc/stat, computes delta values over the sampling interval, derives per-core and global usage percentages, and formats results for easy integration with monitoring stacks. It supports deterministic telemetry with a low memory and CPU footprint suitable for dense hosts.\n\nCore features include configurable sampling interval, per-core breakdown, and export in JSON or CSV. Optional capabilities cover remote data collection via SSH in agentless mode, multi-host collection, and simple hooks for alerting systems or dashboards.\n\nUse cases include capacity verification on new hosts, anomaly detection in production, alert tuning for spikes, and post-incident analysis. It is designed for operators who need reliable CPU telemetry without heavy agents, emphasizing correctness, reproducibility, and low operational overhead.\n\nOutputs are timestamped and can include per-core vectors and load averages, enabling historical trend analysis and capacity forecasting. The tool can persist locally or forward telemetry to external systems, and it supports integration with common formats and automation pipelines.
