Abstract

The present disclosure is directed towards systems and methods of configuring a computing environment. A device identifies a template including a declarative language with a first declaration and a second declaration. The device instantiate the template to generate a configuration object corresponding to the first declaration. The device establishes a first configuration of a component using the generated configuration object. The device generates a second configuration of a monitor to monitor a component. The device establishes the monitor to monitor operational state of the component.

Claims

1. A method of configuring a computing environment, comprising:

identifying, by a device, a template comprising a declarative language with a first declaration defining one or more configuration objects to be configured for one or more components of a computing environment, and a second declaration specifying one or more components of the computing environment to monitor;

instantiating, by the device, the template to generate the one or more configuration objects responsive to the first declaration;

establishing, by the device, a first configuration of the one or more components using the generated one or more configuration objects;

generating, by the device responsive to the second declaration, a second configuration of one or more monitors to monitor the one or more components; and

establishing, by the device using the second configuration, the one or more monitors to monitor operational state of the one or more components.

2. The method of claim 1, comprising:

composing the template using one or more pre-existing templates.

3. The method of claim 1, comprising:

storing a master copy of the template on a server remote from the device;

auditing the first configuration of the one or more components on the device to identify a deviation from the master copy; and

generating, responsive to identifying the deviation, an alert.

4. The method of claim 1, comprising:

providing the template with a first parameter corresponding to a number of servers to be used for the one or more components, and a second parameter corresponding to an IP address for each of the servers to be used for the one or more components;

receiving, by the device, a first value for the first parameter and a second value for the second parameter; and

instantiating, by the device, the template using the first value for the first parameter and the second value for the second parameter to generate the one or more configuration objects responsive to the first declaration.

5. The method of claim 1, comprising:

instantiating the template with a first value of a parameter to generate the one or more configuration objects responsive to the first declaration; and

instantiating the template with a second value of the parameter different from the first value to generate a second one or more configuration objects responsive to the first declaration, the second one or more configuration objects different from the one or more configuration objects.

6. The method of claim 1, wherein the one or more configuration objects comprises a second template comprising a third declaration, the method comprising:

instantiating the second template responsive to the device instantiating the first template to generate a second one or more configuration objects responsive to the third declaration.

7. The method of claim 1, comprising:

monitoring, by the one or more monitors established using the second configuration, traffic transactions of the one or more components established using the first configuration.

8. The method of claim 1, comprising:

configuring, using the first configuration, a plurality of components on a plurality of devices in the computing environment; and

aggregating monitored operation state information of each of the plurality of components established using the first configuration.

9. The method of claim 1, comprising:

establishing, via the second configuration, a filter property of the one or more monitors to select a type of operational state information to be collected.

10. The method of claim 1, comprising:

removing the one or more components from the computing environment; and

removing, by the device responsive to removal of the one or more components, the one or more configuration objects from the computing environment.

11. A system to configure a computing environment, comprising:

a compiler executable by a device comprising one or more processors coupled to memory to;

identify a template comprising a declarative language with a first declaration defining one or more configuration objects to be configured for one or more components of a computing environment, and a second declaration specifying one or more components of the computing environment to monitor;

instantiate the template to generate the one or more configuration objects responsive to the first declaration; and

generate, responsive to the second declaration, a second configuration of one or more monitors to monitor the one or more components; and

a configuration engine executable by the device to;

establish a first configuration of the one or more components based on the generated one or more configuration objects; and

establish, based on the second configuration, the one or more monitors to monitor operational state of the one or more components.

12. The system of claim 11, wherein the device is further configured to:

compose the template using one or more pre-existing templates.

13. The system of claim 11, comprising

a server, remote from the device, configured to store a master copy of the template;

the device further configured to;

audit the first configuration of the one or more components on the device to identify a deviation from the master copy; and

generate, responsive to the deviation, an alert.

14. The system of claim 11, wherein the device is further configured to:

provide the template with a first parameter corresponding to a number of servers to be used for the one or more components, and a second parameter corresponding to an IP address for each of the servers to be used for the one or more components;

receive a first value for the first parameter and a second value for the second parameter; and

instantiate the template based on the first value for the first parameter and the second value for the second parameter to generate the one or more configuration objects responsive to the first declaration.

15. The system of claim 11, wherein the device is further configured to:

instantiate the template with a first value of a parameter to generate the one or more configuration objects responsive to the first declaration; and

instantiate the template with a second value of the parameter different from the first value to generate a second one or more configuration objects responsive to the first declaration, the second one or more configuration objects different from the one or more configuration objects.

16. The system of claim 11, wherein the one or more configuration objects comprises a second template comprising a third declaration, the device further configured to:

instantiate the second template responsive to the device instantiating the first template to generate a second one or more configuration objects responsive to the third declaration.

17. The system of claim 11, wherein the device is further configured to:

monitor, via the one or more monitors established using the second configuration, traffic transactions of the one or more components established using the first configuration.

18. The system of claim 11, wherein the device is further configured to:

configure, based on the first configuration, a plurality of components on a plurality of devices in the computing environment; and

aggregate monitored operation state information of each of the plurality of components established using the first configuration.

19. The system of claim 11, wherein the device is further configured to:

establish, via the second configuration, a filter property of the one or more monitors to select a type of operational state information to be collected.

20. The system of claim 11, wherein the device is further configured to:

remove the one or more components from the computing environment; and

remove, responsive to removal of the one or more components, the one or more configuration objects from the computing environment.
