## Investigate usage spikes with Flamegraph [#flamegraph]

![flamegraph](./images/flamegraph.png "Pixie flamegraph")

Debugging is orders of magnitude easier when you can quickly see what your application is doing. Flamegraph, a Pixie always-on visualization, requires no instrumentation, redeploying, or recompiling. It works for compiled languages - Go, C+, Rust, to name a few. Flamegraph tells you in a glance what functions your application is spending time on, and where you have hot spots. Flamegraph is especially useful for hierarchical resource use, like disk usage and CPU utilization. For more information on how to read Flamegraph, see [the Pixie documentation](https://docs.pixielabs.ai/tutorials/profiler#reading-the-flamegraph).
