  • Publication number: 20250068545
    Abstract: A computing environment determines, by an initialization process, a monitor instance identifier of an instance of an application, wherein the initialization process initializes monitoring of the instance of the application. The computing environment generates, by the initialization process, a system call argument based on a pseudo-randomly generated identifier. The computing environment makes, by the initialization process, a system call comprising the system call argument. The computing environment determines, by a kernel-space Berkeley packet filter (BPF), to monitor the instance of the application based on the system call. The computing environment extracts, by the kernel-space BPF, the pseudo-randomly generated identifier from the system call argument to obtain the monitor instance identifier. The computing environment stores, in a watch list, the monitor instance identifier and the pseudo-randomly generated identifier.
