0x.tools is a set of Linux performance analysis tools (xcapture and xtop) that use modern eBPF to sample thread-level system activity such as sleeps, disk I/O waits, TCP connections, and stack traces. xcapture records samples to CSV/Parquet files, which xtop visualizes in a terminal UI powered by DuckDB.
Use cases
- diagnose why processes or threads are sleeping or waiting on a Linux server
- sample kernel and user-level thread stack traces for performance troubleshooting
- analyze disk I/O waits and per-block-device latency drilldowns
- monitor TCP connection metrics at the thread level
- record always-on low-overhead system activity samples to CSV/Parquet for later analysis
- explore captured performance data interactively in a terminal UI
When to choose
- you need fine-grained, thread-level visibility into Linux system behavior without heavyweight APM agents
- you want low-overhead eBPF-based sampling with offline analysis via DuckDB
- you are troubleshooting production Linux performance issues and need stack traces and wait-state breakdowns
When to avoid
- you are not on Linux or your kernel is older than 5.11/5.14 (xcapture requires modern eBPF features)
- you need a turnkey monitoring dashboard with alerting rather than a sampling and analysis tool
- you need support for legacy kernels or non-Linux systems for live capture
