Abstract

Implementations of the present disclosure provide methods including executing a profiling session to profile one or more applications running on a virtual machine executed on a server, collecting profiling data over a first time interval during the profiling session, receiving user input generated at a client device, the client device being in communication with the server, in response to the user input, generating a snapshot corresponding to a subset of the profiling data, the snapshot being identified based on a second time interval that is within the first time interval, and transmitting the profiling data to generate a snapshot view for display on a client device, the snapshot view corresponding to the subset of the profiling data.

Claims

1. A computer-implemented method, comprising:

executing a profiling session to profile one or more applications running on a virtual machine executed on a server;

collecting profiling data over a first time interval during the profiling session;

receiving user input generated at a client device, the client device being in communication with the server, the user input being received during the profiling session;

in response to the user input, generating, by the server, a first snapshot marker within the profiling data based on the user input, generating a second snapshot marker within the profiling data, wherein a second time interval is defined between the first and second snapshot markers, and generating a snapshot corresponding to a subset of the profiling data, the snapshot being generated during the profiling session and being identified based on the second time interval that is within the first time interval;

transmitting, from the server and to the client device, only the subset of the profiling data to generate a snapshot view for display on the client device, the snapshot view corresponding to the subset of the profiling data; and

receiving, by the server, a user selection of a called methods entry point, and in response, providing a list of methods called during the snapshot.

2. The computer-implemented method of claim 1, further comprising receiving user input indicating one or more logical filter definitions, wherein the snapshot is generated based on the one or more logical filter definitions.

3. The computer-implemented method of claim 2, wherein the one or more logical filter definitions comprise one or more of a class name, a method name, a thread name, an application name, a user name, and an execution path.

4. The computer-implemented method of claim 1, further comprising receiving second user input during running of the application, wherein the second snapshot marker is generated based on the second user input.

5. The computer-implemented method of claim 1, further comprising:

determining a report interval, the report interval indicating a frequency for generating a status report of an application;

generating a plurality of status reports based on the report interval, wherein each status report and a corresponding time are provided in the profiling data; and

determining the second time interval based on a time corresponding to a first status report of the plurality of status reports and a time corresponding to a second status report of the plurality of status reports.

6. The computer-implemented method of claim 5, wherein each report status comprises at least one of a processing unit load, a number of performed garbage collections, and a time stamp.

7. The computer-implemented method of claim 1, wherein the snapshot is generated in response to an application performing a specified event.

8. The computer-implemented method of claim 1, further comprising generating a second snapshot corresponding to a subset of the profiling data associated with the snapshot, the second snapshot being generated based on applying a logical filter to the profiling data associated with the snapshot.

9. Anon-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

executing a profiling session to profile one or more applications running on a virtual machine executed on a server;

collecting profiling data over a first time interval during the profiling session;

receiving user input generated at a client device, the client device being in communication with the server, the user input being received during the profiling session;

receiving user input generated at a client device, the client device being in communication with the server, the user input being received during the profiling session;

in response to the user input, generating, by the server, a first snapshot marker within the profiling data based on the user input, generating a second snapshot marker within the profiling data, wherein a second time interval is defined between the first and second snapshot markers, and generating a snapshot corresponding to a subset of the profiling data, the snapshot being generated during the profiling session and being identified based on the second time interval that is within the first time interval;

transmitting, from the server and to the client device, only the subset of the profiling data to generate a snapshot view for display on the client device, the snapshot view corresponding to the subset of the profiling data; and

receiving, by the server, a user selection of a called methods entry point, and in response, providing a list of methods called during the snapshot.

10. The non-transitory computer-readable storage medium of claim 9, wherein the operations further comprise receiving user input indicating one or more logical filter definitions, wherein the snapshot is generated based on the one or more logical filter definitions.

11. The non-transitory computer-readable storage medium of claim 10, wherein the one or more logical filter definitions comprise one or more of a class name, a method name, a thread name, an application name, a user name, and an execution path.

12. The non-transitory computer-readable storage medium of claim 9, wherein the operations further comprise receiving second user input during running of the application, wherein the second snapshot marker is generated based on the second user input.

13. The non-transitory computer-readable storage medium of claim 9, wherein the operations further comprise:

defining a report interval, the report interval indicating a frequency for generating a status report of a back-end application;

generating a plurality of status reports based on the report interval, wherein each status report and a corresponding time are provided in the profiling data; and

determining the second time interval based on a time corresponding to a first status report of the plurality of status reports and a time corresponding to a second status report of the plurality of status reports.

14. The non-transitory computer-readable storage medium of claim 13, wherein each report status comprises at least one of a processing unit load, a number of performed garbage collections, and a time stamp.

17. A system, comprising:
