Abstract

A computer receives a heartbeat message that includes both program reset information and at least one segment, of the heartbeat message, that is configured to indicate whether or not a first program is functioning correctly. The computer determines if the heartbeat message includes the indication that the first program is functioning correctly. If the computer determines that the heartbeat message indicates that the first program is functioning correctly, then the computer sends a data stream to the first program.

Claims

1. A method of monitoring a hierarchy of program components executing on computer hardware, the method comprising:

a computer receiving a heartbeat message that includes both program reset information and at least one segment of the heartbeat message that is configured to store an indication that a first program is functioning correctly;

the computer determining if the heartbeat message includes the indication that the first program is functioning correctly; and

responsive to the determination that the heartbeat message includes the indication that the first program is functioning correctly, the computer sending a data stream to the first program.

2. The method of claim 1, wherein if the first program is functioning correctly, then the at least one segment of the heartbeat message is appended, by the computer, to include the indication that the first program is functioning correctly.

3. The method of claim 1, the method further comprising:

responsive to the determination that the heartbeat message does not include the indication that the first program is functioning correctly, the computer determining that the first program has failed.

4. The method of claim 3, the method further comprising:

responsive to the determination that the first program has failed;

the computer redirecting the data stream to a second program or to an endpoint, wherein the endpoint is a point of termination or completion in a computational process.

5. The method of claim 3, the method further comprising:

responsive to the determination that the first program has failed;

the computer initiating a restart of the first program.

6. The method of claim 1, the method further comprising:

responsive to the determination that the heartbeat message does not include the indication that the first program is functioning correctly, the computer determining if a threshold number of heartbeat messages have not been appended with the indication that the first program is functioning correctly; and

responsive to the determination that the threshold number of heartbeat messages have not been appended with the indication that the first program is functioning correctly, the computer determining that the first program has failed.

7. The method of claim 1, wherein the computer appends the at least one segment using a third program that is configured to monitor and append the heartbeat message.

8. A computer program product for monitoring a hierarchy of program components executing on computer hardware, the computer program product comprising:

one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising;

program instructions to receive a heartbeat message that includes both program reset information and at least one segment of the heartbeat message that is configured to store an indication that a first program is functioning correctly;

program instructions to determine if the heartbeat message includes the indication that the first program is functioning correctly; and

program instructions to respond to the determination that the heartbeat message includes the indication that the first program is functioning correctly, by sending a data stream to the first program.

9. The computer program product claim 8, wherein if the first program is functioning correctly, then the at least one segment of the heartbeat message is appended, by the computer, to include the indication that the first program is functioning correctly.

10. The computer program product of claim 8, the method further comprising:

responsive to the determination that the heartbeat message does not include the indication that the first program is functioning correctly, the computer determining that the first program has failed.

11. The computer program product of claim 10, the method further comprising:

responsive to the determination that the first program has failed;

the computer redirecting the data stream to a second program or to an endpoint, wherein the endpoint is a point of termination or completion in a computational process.

12. The computer program product of claim 10, the method further comprising:

responsive to the determination that the first program has failed;

the computer initiating a restart of the first program.

13. The computer program product of claim 8, the method further comprising:

responsive to the determination that the heartbeat message does not include the indication that the first program is functioning correctly, the computer determining if a threshold number of heartbeat messages have not been appended with the indication that the first program is functioning correctly; and

responsive to the determination that the threshold number of heartbeat messages have not been appended with the indication that the first program is functioning correctly, the computer determining that the first program has failed.

14. A computer system for monitoring a hierarchy of program components executing on computer hardware, the computer system comprising:

one or more computer processors;

one or more computer-readable storage media;

program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising;

program instructions to receive a heartbeat message that includes both program reset information and at least one segment of the heartbeat message that is configured to store an indication that a first program is functioning correctly;

program instructions to determine if the heartbeat message includes the indication that the first program is functioning correctly; and

program instructions to respond to the determination that the heartbeat message includes the indication that the first program is functioning correctly, by sending a data stream to the first program.

15. The computer system of claim 14, wherein if the first program is functioning correctly, then the at least one segment of the heartbeat message is appended, by the computer, to include the indication that the first program is functioning correctly.

16. The computer system of claim 14, the method further comprising:

responsive to the determination that the heartbeat message does not include the indication that the first program is functioning correctly, the computer determining that the first program has failed.

17. The computer system of claim 16, the method further comprising:

responsive to the determination that the first program has failed;

the computer redirecting the data stream to a second program or to an endpoint, wherein the endpoint is a point of termination or completion in a computational process.

18. The computer system of claim 16, the method further comprising:

responsive to the determination that the first program has failed;

the computer initiating a restart of the first program.

19. The computer system of claim 14, the method further comprising:

responsive to the determination that the heartbeat message does not include the indication that the first program is functioning correctly, the computer determining if a threshold number of heartbeat messages have not been appended with the indication that the first program is functioning correctly; and

responsive to the determination that the threshold number of heartbeat messages have not been appended with the indication that the first program is functioning correctly, the computer determining that the first program has failed.

20. The computer system of claim 14, wherein the computer appends the at least one segment using a third program that is configured to monitor and append the heartbeat message.
