Process management
View Patent ↗A technique for managing a plurality of processes is disclosed. The technique includes reading a process manager configuration file and executing a set of actions according to the timing and conditions specified in the process manager configuration file. The process manager configuration file is a markup language-based specification of the timing and conditions of the execution of the processes.
1. A method of managing a plurality of processes, including:
reading a process manager configuration file associated with a plurality of network services processes that are being simultaneously managed by a process manager, wherein the network services associated with the plurality of network services processes include two or more of the following: Network Time Protocol (NTP), Secure Shell (SSH), Simple Network Management Protocol (SNMP), Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Remote Authentication Dial In User Service (RADIUS), and Apache;
using a process manager to execute a set of actions according to the timing and conditions specified in the process manager configuration file;
wherein the process manager is configured to:
a) execute a first data monitor action specified in the process manager configuration file as one of the set of actions based at least upon:
1) a current data value associated with a current state of a network service process, and
2) a change indication associated with whether a previous state of the network service process has changed with respects to the current state of a network service process; and
b) execute a second data monitor action specified in the process manager configuration file as one of the set of actions based at least upon:
1) a configuration value associated with a network service configuration file, and
2) an active configuration value associated with an active network service configuration file;
wherein each data monitor action specifies a network services command comprising a shell script or a binary executable associated with the network service process;
restarting the network service associated with the network service configuration file, in the event that the network service configuration file and the active network service configuration file are different; and
wherein the process manager configuration file is a markup language-based specification of the timing and conditions of the execution of the network services processes.
2. The method as recited in claim 1 , wherein the process manager configuration file is an XML file.
3. The method as recited in claim 1 , wherein a process manager performs the reading and the executing of the process manager configuration file.
4. The method as recited in claim 1 , wherein one of the actions is executed when a process manager starts.
5. The method as recited in claim 1 , wherein one of the actions executes conditionally.
6. The method as recited in claim 1 , wherein one of the actions executes periodically.
7. The method as recited in claim 1 , wherein one of the actions executes when a process manager ends.
8. The method as recited in claim 1 , wherein one of the actions specifies a command.
9. The method as recited in claim 1 , wherein one of the actions specifies a command and the command specifies an executable.
10. The method as recited in claim 1 , further including executing an executable specified in the process manager configuration file.
11. The method as recited in claim 1 , wherein executing includes:
reading a value of a specified variable; and
executing an action based on whether the value meets a condition.
12. The method as recited in claim 1 , wherein executing includes:
reading a value of a specified variable; and
executing an action based on whether the value has changed.
13. A system for managing a plurality of processes, including:
a processor; and
a process manager configured to:
read a process manager configuration file associated with a plurality of network services processes that are being simultaneously managed by a process manager, wherein the network services associated with the plurality of network services processes include two or more of the following: Network Time Protocol (NTP), Secure Shell (SSH), Simple Network Management Protocol (SNMP), Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Remote Authentication Dial In User Service (RADIUS), and Apache;
execute a set of actions according to the timing and conditions specified in the process manager configuration file;
wherein the process manager is configured to:
a) execute a first data monitor action specified in the process manager configuration file as one of the set of actions based at least upon:
1) a current data value associated with a current state of a network service process, and
2) a change indication associated with whether a previous state of the network service process has changed with respects to the current state of a network service process; and
b) execute a second data monitor action specified in the process manager configuration file as one of the set of actions based at least upon:
1) a configuration value associated with a network service configuration file, and
2) an active configuration value associated with an active network service configuration file;
wherein each data monitor action specifies a network services command comprising a shell script or a binary executable associated with the network service process;
restarting the network service associated with the network service configuration file, in the event that the network service configuration file and the active network service configuration file are different; and
wherein the process manager configuration file is a markup language based specification of the timing and conditions of the execution of the network services processes.
14. The system as recited in claim 13 , wherein the process manager configuration file is an XML file.
15. The system as recited in claim 13 , wherein one of the actions is executed when a process manager starts.
16. The system as recited in claim 13 , wherein one of the actions executes conditionally.
17. The system as recited in claim 13 , wherein one of the actions executes periodically.
18. The system as recited in claim 13 , wherein one of the actions executes when a process manager ends.
19. The system as recited in claim 13 , wherein one of the actions specifies a command.
20. A computer program product for managing a plurality of processes, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
reading a process manager configuration file associated with a plurality of network services processes that are being simultaneously managed by a process manager, wherein the network services associated with the plurality of network services processes include two or more of the following: Network Time Protocol (NTP), Secure Shell (SSH), Simple Network Management Protocol (SNMP), Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Remote Authentication Dial In User Service (RADIUS), and Apache;
using a process manager to execute a set of actions according to the timing and conditions specified in the process manager configuration file;
wherein the process manager is configured to:
a) execute a first data monitor action specified in the process manager configuration file as one of the set of actions based at least upon:
1) a current data value associated with a current state of a network service process, and
2) a change indication associated with whether a previous state of the network service process has changed with respects to the current state of a network service process; and
b) execute a second data monitor action specified in the process manager configuration file as one of the set of actions based at least upon:
1) a configuration value associated with a network service configuration file, and
2) an active configuration value associated with an active network service configuration file;
wherein each data monitor action specifies a network services command comprising a shell script or a binary executable associated with the network service process;
restarting the network service associated with the network service configuration file, in the event that the network service configuration file and the active network service configuration file are different; and
wherein the process manager configuration file is a markup language-based specification of the timing and conditions of the execution of the network services processes.
21. The computer program product as recited in claim 20 , wherein the process manager configuration file is an XML file.
