Abstract
A method for tracing function execution includes instantiating, by at least one hardware processor of a computing node, a user-defined function (UDF) server associated with a plurality of configurations. A plurality of child processes of the UDF server are instantiated using the plurality of configurations. A filtering process is configured at an operating system (OS) kernel of the computing node using a child process of the plurality of child processes. The filtering process includes a set of system call categories and a corresponding set of filtering policies. A system call received at the OS kernel and associated with a system call category of the set of system call categories is detected to violate a corresponding filtering policy of the set of filtering policies. A tracing event of the system call is initiated based on the detecting.
