Override kernel version check
editOverride kernel version check
editThe -no-kernel-version-check
flag, or the no-kernel-version-check
key in the Universal Profiling Agent configuration file, controls the kernel version compatibility check during the Universal Profiling Agent’s startup process. The kernel version compatibility check enforces the minimum kernel version supported, and prevents the profiling agent from running on certain kernel versions with known issues. When the no-kernel-version-check
is set to true
, the compatibility check is bypassed, allowing Universal Profiling Agent execution to proceed regardless of the kernel version. By default, this option is set to false
, and the kernel compatibility version check is performed as usual.
Take extra caution when using this configuration option, especially when running the Universal Profiling Agent on older kernels with backported eBPF functionalities. Setting this option to true
on kernels with unfixed eBPF bugs can crash your system.
Host agent configuration example
editThe following example shows how to configure the -no-kernel-version-check
in the Universal Profiling agent CLI:
sudo pf-host-agent/pf-host-agent -no-kernel-version-check=true
