Managed execution and expiration of agent commands
Methods and apparatus for managing the expiration and execution of commands sent from a remote system having administration functions to an agent residing on a computer system are disclosed. An exemplary method includes receiving, at an agent, one or more commands, storing the one or more received commands, retrieving the one or more stored commands, and determining whether the one or more retrieved commands can be executed by comparing at least one time parameter associated with the agent to at least one time parameter associated with the one or more retrieved commands.
1. A method of evaluating one or more commands to be executed, the method comprising:
retrieving, by an agent, one or more stored commands, wherein at least one command of the one or more stored commands comprises a check-in expiration time parameter; and
determining whether the at least one command of the one or more retrieved commands can be executed by comparing the check-in expiration time parameter and a last check-in time associated with the agent, wherein the check-in expiration parameter indicates whether the at least one command is to execute based upon whether the agent checked-in to the remote administration system.
2. The method according to claim 1 , wherein the last check-in time comprises a duration of time that has elapsed since the agent has last contacted a remote system.
3. The method according to claim 2 , wherein when the last check-in time is greater than the check-in expiration time parameter, preventing the at least one command from executing.
4. The method according to claim 2 , wherein when the last check-in time is less than the check-in expiration time parameter, executing the at least one command.
5. The method according to claim 1 , wherein the one or more commands are received from a remote system.
6. The method according to claim 1 , wherein the one or more commands are received from a remote system located in a cloud computing environment.
7. The method according to claim 2 , wherein the at least one command of the one or more stored commands further comprises a scheduled execution time parameter that defines a scheduled execution time for the at least one command to be executed, and wherein the at least one command is executed when (i) the last check-in time is less than the check-in expiration time and (ii) the scheduled execution time is met.
8. The method according to claim 2 , wherein the at least one command further comprises an additional parameter, and wherein the at least one command is executed when (i) the last check-in time is less than the check-in expiration time; (ii) a scheduled execution time is before a current time; and (iii) the additional parameter indicates that the at least one command can be executed.
9. The method according to claim 8 , wherein the additional parameter comprises at least one of:
a dependency parameter;
an override/update parameter; and
a reorder parameter.
10. A non-transitory, computer-readable storage medium, encoded with processor readable instructions to perform a method for evaluating one or more commands for execution by an agent, the method comprising:
retrieving, by an agent, one or more stored commands, wherein at least one command of the one or more stored commands comprises a check-in expiration time parameter; and
determining whether the at least one command of the one or more retrieved commands can be executed by comparing the check-in expiration time parameter and a last check-in time associated with the agent, wherein the check-in expiration parameter indicates whether the at least one command is to execute based upon whether the agent checked-in to the remote administration system.
11. The non-transitory, computer-readable storage medium of claim 10 , wherein the last check-in time comprises a duration of time that has elapsed since the agent last contacted a remote system.
12. The non-transitory, computer-readable storage medium of claim 11 , wherein when the last check-in time is greater than the check-in expiration time parameter, preventing the at least one command from executing.
13. The non-transitory, computer-readable storage medium of claim 11 , wherein when the last check-in time is less than the check-in expiration time parameter, executing the at least one command.
14. The non-transitory, computer-readable storage medium of claim 11 , wherein the at least one command of the one or more stored commands further comprises a scheduled execution time parameter that defines a scheduled execution time for the at least one command to be executed, and wherein the at least one command is executed when (i) the last check-in time is less than the check-in expiration time and (ii) the scheduled execution time is met.
15. The non-transitory, computer-readable storage medium of claim 11 , wherein the at least one command further comprises an additional parameter, and wherein the at least one command is executed when (i) the last check-in time is less than the check-in expiration time; (ii) a scheduled execution time is before a current time; and (iii) the additional parameter indicates that the at least one command can be executed.
16. A system comprising:
at least one processor; and
memory encoding computer executable instructions that, when executed by the at least one processor, perform a method comprising:
retrieving, by an agent, one or more stored commands, wherein at least one command of the one or more stored commands comprises a check-in expiration time parameter; and
determining whether the at least one command of the one or more retrieved commands can be executed by comparing the check-in expiration time parameter and a last check-in time associated with the agent, wherein the check-in expiration parameter indicates whether the at least one command is to execute based upon whether the agent checked-in to the remote administration system.
17. The system according to claim 16 , wherein the last check-in time comprises a duration of time that has elapsed since the agent has last contacted a remote system.
18. The system according to claim 17 , wherein the at least one command of the one or more stored commands further comprises a scheduled execution time parameter that defines a scheduled execution time for the at least one command to be executed, and wherein the at least one command is executed when (i) the last check-in time is less than the check-in expiration time and (ii) the scheduled execution time is met.
19. The system according to claim 17 , wherein the at least one command further comprises an additional parameter, and wherein the at least one command is executed when (i) the last check-in time is less than the check-in expiration time; (ii) a scheduled execution time is before a current time; and (iii) the additional parameter indicates that the at least one command can be executed.
20. The system according to claim 17 , wherein the additional parameter comprises at least one of:
a dependency parameter;
an override/update parameter; and
a reorder parameter.
