About Parca
Parca collects profiling data all the time, at low overhead, so you have it when a performance problem appears. The Parca Agent uses eBPF in the Linux kernel to sample running programs with no instrumentation, in any language or framework. Results break down by method name, class name and line number.
The server has built-in storage, a multi-dimensional data model and a label-selector query language. It finds targets through service discovery or static configuration, can push or pull profiles, and can compare profiles over time to show hot paths. It runs as a binary or on Kubernetes.
Strengths
- Zero-instrumentation profiling through eBPF
- Line-level breakdown of CPU and memory use
- Continuous collection at low overhead
- Can compare profiles across time ranges
Limitations
- The eBPF agent requires Linux
- Aimed at server infrastructure rather than desktop use
