# eBPF-Based Instrumentation

## Supported Versions

Odigos eBPF-Based Java Instrumentation requires a Java Virtual Machine runtime version of **8** through **25**.

<Note>
  Odigos eBPF-based data collection requires, at minimum, platforms that have underlying Linux kernel versions of 5.4.0.

  The required Linux capabilities depend on your kernel version:

  * **Kernel 5.4 – 5.7**: requires `CAP_SYS_ADMIN`.
  * **Kernel 5.8 and later**: requires `CAP_BPF` and `CAP_SYS_PTRACE`.

  We recommend running on kernel 5.8 or later when possible, as the more granular capabilities (`CAP_BPF` and `CAP_SYS_PTRACE`) follow the principle of least privilege compared to `CAP_SYS_ADMIN`.
</Note>

The following JVM runtimes are continuously tested and verified:

| JVM Runtime | Version |
| ----------- | ------- |
| OpenJDK     | 8       |
| OpenJDK     | 11      |
| OpenJDK     | 17      |
| Azul Zulu   | 8       |
| Azul Zulu   | 11      |
| Azul Zulu   | 17      |
