Real time monitoring of computer for determining speed of various processes
View Patent ↗A system is disclosed for identifying one or more causes of a computer executing one or more processes running slowly, the system includes: apparatus for detecting states of one or more threads of the one or more processes; apparatus for identifying one or more of said one or more processes that have one or more threads with wait states that occur above a threshold to indicate which modules within a process or processes is causing said computer to run slowly. In one embodiment the system as the apparatus for detecting states periodically polls the one or more threads of the processes. The system can also include a data structure to store the states of each of said one or more threads each time said thread is polled. The system can be one in which one or more threads are UI threads.
1. A system comprising at least one processor operatively associated with a computer memory, the processor being configured to identify one or more causes for a slowdown of a computer executing one or more processes, each of said one or more processes comprising one or more threads, the processor being operable to:
detect states of said one or more threads, and identify at least one thread in a wait state;
collect thread performance information of said at least one thread in a wait state, said performance information including data indicative of a performance of different functions of said process;
identify based on said performance information, one or more functions which are the cause for said slowdown;
associate between said identified functions and their respective modules; and identify, based on at least, said performance information of said one or more functions and on data related to their associated respective modules, one or more modules from among said modules, which are the cause for said slowdown in said computer.
2. The system of claim 1 , wherein said processor is configured to periodically poll said one or more threads of the one or more processes, in order to detect said states.
3. The system of claim 1 , also including: a data structure configured to store said thread performance information.
4. The system of claim 1 , wherein said one or more threads are UI threads.
5. The system of claim 1 wherein said processor is configured to utilize hooking of voluntary API calls in order to collect said performance information.
6. The system of claim 5 , wherein said one or more threads are UI threads.
7. The system of claim 1 , wherein said processor is further operable to utilize a knowledge base to store information for translating said performance information into data indicative of one or more functions and respective modules which are the cause for said slowdown.
8. The system of claim 7 , wherein said information stored in said knowledge base includes one or more of: historical, cross-system module baseline information.
9. The system of claim 1 , wherein said processor is configured to utilize an Operating System maintained thread state store in order to detect states of said one or more threads.
10. The system of claim 1 , wherein said performance information is normalized with respect to time.
11. The system of claim 1 wherein said processor is configured to intercept a respective process launch event of said one or more processes, thereby enable to detect states of said one or more threads.
12. The system of claim 1 wherein said processor is configured to poll call stacks of said at least one thread in wait state, in order to collect said performance information.
13. The system of claim 1 wherein said processor is configured to utilize heuristics in order to identify, based on said performance information, one or more functions and their respective modules from among said modules, which are the cause for said slowdown in said computer.
14. The system of claim 1 , wherein said processor is configured to utilize a data storage containing data mapping between functions and respective modules in order to associate between said functions and their respective modules.
15. A method for identifying one or more causes for a slowdown of a computer executing one or more processes, each of said one or more processes comprising one or more threads, the method comprising:
detecting states of said one or more threads, and identifying at least one thread in a wait state;
collecting thread performance information of said at least one thread in wait state, said performance information includes data being indicative of a performance of different functions of said process;
identifying based on at least said performance information, one or more functions which are the cause for said slowdown;
associating between said identified functions and their respective modules; and
identifying, based on at least said performance information of said one or more functions and on data related to their associated related modules, one or more modules from among said modules, which are the cause for said slowdown in said computer.
16. A none-transitory program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for identifying one or more causes for a slowdown of a computer executing one or more processes, each of said one or more processes comprising one or more threads, the method comprising:
detecting states of said one or more threads, and identifying at least one thread in a wait state;
collecting thread performance information of said at least one thread in wait state, said performance information includes data being indicative of a performance of different modulesfunctions of said process;, which are associated with said at least one thread in a wait state; and
identifying based on at least said performance information, one or more functions which are the cause for said slowdown;
associating between said identified functions and their respective modules; and
identifying, based on at least said performance information of said one or more functions and on data related to their associated related modules, one or more modules from among said modules, which are the cause for said slowdown in said computer.
