I patched the source file of bcc-tools (function bcc_usdt_enable_probe and deeper), compiled and installed this custom version with some printfs to trace why it's failing and it turns out that when parsing the probes list, the probe defined in my program was seen as string with additional quotes, something like this: ""probe-main"". BCC - Tools for BPF-based Linux IO analysis, networking, monitoring, and more - iovisor/bcc * Allow argdist to enable USDT probes without a pid The current code would only pass the pid to the USDT class, thereby not allowing USDT probes to be enabled from the binary path only.
