Dynamically-updatable deep transactional monitoring systems and methods
Provided herein are system, method and computer program products for providing dynamically-updatable deep transactional monitoring of running applications in real-time. A method for monitoring a target software application operates by injecting a software engine into a new thread within a target process of the target software application. The method then retrieves a monitoring script and initiates execution of the monitoring script within the software engine. The monitoring script determining the address functions and calls to the functions and inserts a trampoline call within the one or more functions. The trampoline saves the execution state of the target process and calls a corresponding monitoring function that to retrieves data associated with the target process. The method then restoring the execution state of the target process and resumes execution of the target function.
1 . A computer-implemented method of modifying a target application executing in a target process including one or more target threads, the computer-implemented method comprising:
creating a monitoring thread in the target process different than the one or more target threads during runtime of the target process;
starting execution of a software engine in the monitoring thread in the target process, during the runtime of the target process, to execute one or more monitoring scripts during the runtime of the target process, wherein the one or more monitoring scripts executing in the monitoring thread are configured to access memory within the target process and the target application executing in the one or more target threads are configured to access the memory within the target process;
modifying, by execution of the one or more monitoring scripts, executable code of the target application during the runtime of the target process, wherein the modified executable code is configured to generate monitoring data from the runtime of the target process and to store the monitoring data into the memory during the runtime of the target process, wherein the modifying operation includes modifying one or more instructions in a target function of the target application during runtime of the target process to include instructions that call monitoring interceptor code within the one or more monitoring scripts; and
accessing, by the one or more monitoring scripts in the monitoring thread, the monitoring data in the memory after the monitoring data is stored into the memory.
2 . The computer-implemented method of claim 1 , further comprising:
updating the one or more monitoring scripts from a source external of the target process without restarting the target process.
3 . The computer-implemented method of claim 1 , wherein the one or more monitoring scripts identify one or more functions of the target application to monitor and data from the one or more functions to monitor.
4 . The computer-implemented method of claim 1 , wherein the one or more monitoring scripts send monitored data to an agent external of the target process.
5 . A computerized system for modifying a target application executing in a target process including one or more target threads, the computerized system comprising:
memory configured to store executable program code and data; and
at least one hardware processor configured to create a monitoring thread in the target process different than the one or more target threads during runtime of the target process, execute a software engine in the monitoring thread in the target process, during the runtime of the target process, to execute one or more monitoring scripts during the runtime of the target process, wherein the one or more monitoring scripts executing in the monitoring thread are configured to access the memory within the target process and the target application executing in the one or more target threads are configured to access the memory within the target process, modify, by execution of the one or more monitoring scripts, executable code of the target application during the runtime of the target process, wherein the modified executable code is configured to generate monitoring data from the runtime of the target process and to store the monitoring data into the memory during the runtime of the target process, and access, by the one or more monitoring scripts in the monitoring thread, the monitoring data in the memory after the monitoring data is stored into the memory, wherein the at least one hardware processor modifies one or more instructions in a target function of the target application during runtime of the target process to include instructions that call monitoring interceptor code within the one or more monitoring scripts.
6 . The computerized system of claim 5 , wherein the at least one hardware processor further updates the one or more monitoring scripts from a source external of the target process without restarting the target process.
7 . The computerized system of claim 5 , wherein the one or more monitoring scripts identify one or more functions of the target application to monitor and data from the one or more functions to monitor.
8 . The computerized system of claim 5 , wherein the one or more monitoring scripts send monitored data to an agent external of the target process.
9 . One or more tangible non-transitory processor-readable storage media embodied with instructions for executing on one or more processors and circuits of a computing device a process for modifying a target application executing in a target process including one or more target threads, the process comprising:
creating a monitoring thread in the target process different than the one or more target threads during runtime of the target process;
starting execution of a software engine in the monitoring thread in the target process, during the runtime of the target process, to execute one or more monitoring scripts during the runtime of the target process, wherein the one or more monitoring scripts executing in the monitoring thread are configured to access memory within the target process and the target application executing in the one or more target threads are configured to access the memory within the target process;
modifying, by execution of the one or more monitoring scripts, executable code of the target application during the runtime of the target process, wherein the modified executable code is configured to generate monitoring data from the runtime of the target process and to store the monitoring data into the memory during the runtime of the target process, wherein the modifying operation includes modifying one or more instructions in a target function of the target application during runtime of the target process to include instructions that call monitoring interceptor code within the one or more monitoring scripts; and
accessing, by the one or more monitoring scripts in the monitoring thread, the monitoring data in the memory after the monitoring data is stored into the memory.
10 . The one or more tangible non-transitory processor-readable storage media of claim 9 , further comprising:
updating the one or more monitoring scripts from a source external of the target process without restarting the target process.
11 . The one or more tangible non-transitory processor-readable storage media of claim 9 , wherein the one or more monitoring scripts identify one or more functions of the target application to monitor and data from the one or more functions to monitor.
12 . The one or more tangible non-transitory processor-readable storage media of claim 9 , wherein the one or more monitoring scripts send monitored data to an agent external of the target process.
