Managed execution and expiration of agent commands
Examples provided relate to 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. An exemplary method may include 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:
receiving, at an agent, an agent command comprising an identifier, additional execution parameters, and a command, wherein the agent command is received from a remote administration system;
storing the agent command;
retrieving the agent command; and
determining whether the agent command can be executed by comparing a check-in expiration time parameter that is part of the additional execution parameters and a last check-in time associated with the agent, wherein the check-in expiration parameter indicates whether the agent 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 associated with the agent comprises a duration of time that has elapsed since the agent has last contacted the remote administration system.
3. The method according to claim 2 , wherein the last check-in time associated with the agent is greater than the check-in expiration time parameter, and wherein the agent command is discarded and is not executed.
4. The method according to claim 2 , wherein the last check-in time associated with the agent is less than the check-in expiration time parameter, and wherein agent command is executed.
5. The method according to claim 2 , wherein the additional execution parameters further comprise a scheduled execution time, and wherein the agent command is executed when (i) the last check-in time associated with the agent is less than the check-in expiration time; and (ii) the scheduled execution time is after a current time.
6. The method according to claim 2 , wherein the agent command is executed when (i) the last check-in time associated with the agent is less than the check-in expiration time; (ii) a scheduled execution time is before a current time; and (iii) the additional execution parameters further comprise an additional parameter that indicates that the one or more retrieved commands can be executed.
7. The method according to claim 1 , wherein the remote administration system is located in a cloud computing environment.
8. A non-transitory, computer-readable storage medium, encoded with computer executable instructions that, when executed by at least one processor, perform a method for evaluating one or more commands for execution by an agent, the method comprising:
receiving, at an agent, an agent command comprising an identifier, additional execution parameters, and a command, wherein the agent command is received from a remote administration system;
storing the agent command;
retrieving the agent command; and
determining whether the agent command can be executed by comparing a check-in expiration time parameter that is part of the additional execution parameters and a last check-in time associated with the agent, wherein the check-in expiration parameter indicates whether the agent command is to execute based upon whether the agent checked-in to the remote administration system.
9. The non-transitory, computer-readable storage medium of claim 8 , wherein the last check-in time associated with the agent comprises a duration of time that has elapsed since the agent has last contacted the remote administration system.
10. The non-transitory, computer-readable storage medium of claim 9 , wherein the last check-in time associated with the agent is greater than the check-in expiration time parameter, and wherein the agent command is discarded and is not executed.
11. The non-transitory, computer-readable storage medium of claim 9 , wherein the last check-in time associated with the agent is less than the check-in expiration time parameter, and wherein the agent command is executed.
12. The non-transitory, computer-readable storage medium of claim 9 , wherein the additional execution parameters further comprise a scheduled execution time, and wherein the agent command is executed when (i) the last check-in time associated with the agent is less than the check-in expiration time and (ii) the scheduled execution time is after a current time.
13. The non-transitory, computer-readable storage medium of claim 9 , wherein the agent command is executed when (i) the last check-in time associated with the agent is less than the check-in expiration time; (ii) a scheduled execution time is before a current time; and (iii) the additional execution parameters further comprise an additional parameter that indicates that the one or more retrieved commands can be executed.
14. The non-transitory, computer-readable storage medium of claim 9 , wherein the additional parameter comprises one of:
a dependency parameter;
an override/update parameter; and
a reorder parameter.
15. An apparatus comprising:
at least one processor; and
memory encoding computer executable instruction that, when executed by the at least one processor, perform a method comprising:
receiving, at an agent, an agent command comprising an identifier, additional execution parameters, and a command, wherein the agent command is received from a remote administration system;
storing the agent command;
retrieving the agent command; and
determining whether the agent command can be executed by comparing a check-in expiration time parameter that is part of the additional execution parameters and a last check-in time associated with the agent, wherein the check-in expiration parameter indicates whether the agent command is to execute based upon whether the agent checked-in to the remote administration system.
16. The apparatus of claim 15 , wherein the last check-in time associated with the agent comprises a duration of time that has elapsed since the agent has last contacted the remote administration system.
17. The apparatus of claim 16 , wherein the last check-in time associated with the agent is greater than the check-in expiration time parameter, and wherein the agent command is discarded and is not executed.
18. The apparatus of claim 16 , wherein the last check-in time associated with the agent is less than the check-in expiration time parameter, and wherein agent command is executed.
19. The apparatus of claim 16 , wherein the additional execution parameters further comprise scheduled execution time, and wherein the agent command is executed when (i) the last check-in time associated with the agent is less than the check-in expiration time; and (ii) the scheduled execution time is after a current time.
20. The method of claim 6 , wherein the additional parameter comprises one of:
a dependency parameter;
an override/update parameter; and
a reorder parameter.
