denet: a streaming process monitor
denet /de.net/ v. 1. Turkish: to monitor, to supervise, to audit. 2. to track metrics of a running process.
Denet is a lightweight streaming process monitor. It tracks CPU, memory, I/O, and threads for a running process (and its children), with adaptive sampling and optional GPU / eBPF support.
Installation
pip install denet # Python package
cargo install denet # Rust binary
Or install the conda package from the almost-conductor channel:
# pixi
pixi workspace channel add https://prefix.dev/almost-conductor
pixi add denet
# conda
conda install -c https://prefix.dev/almost-conductor denet
Optional features for the Rust binary:
cargo install denet --features gpu # NVIDIA GPU monitoring (requires drivers; enable per run with --gpu)
cargo install denet --features ebpf # eBPF profiling (Linux only, requires clang)
Usage
# Run a command and monitor it
denet run python train.py
# Attach to an existing process
denet attach 1234
# Save metrics as JSONL
denet --json --out metrics.jsonl run python train.py
# Turn a saved run into a report (timelines, regime detection, eBPF syscalls)
pip install 'denet[report]'
denet-report metrics.jsonl -o report.html
CPU usage follows the top convention: 100% = one fully utilized core, so a 4-core workload shows 400%.
Sampling starts at 100 ms and ramps up to 1 s after 10 s of runtime (adaptive). Override with -i / -m:
denet -i 50 -m 500 run python train.py
