Abstract

Methods and systems for a storage system are provided. The methods include maintaining a logical object associated with a resource of a storage system by a management console; creating a first policy associated with the logical object; selecting an annotation category associated with the logical object and assigning a value to the annotation category, where the annotation category defines an attribute associated with the logical object; providing a duration for generating an alert when the first policy is violated; assigning a threshold value for first policy violation; and setting an indicator for foregoing an alert associated with a second policy, when the first policy is violated.

Claims

1. A machine implemented method, comprising;

representing by a management console a plurality of resources of a networked storage system with a plurality of infrastructure objects, the plurality of resources used for storing and retrieving data at and from a plurality of storage devices, where each of the plurality of infrastructure objects is associated with a performance counter to monitor resource performance for executing client requests for storing and retrieving data;

selecting an infrastructure object from among the plurality of infrastructure objects, where the plurality of infrastructure objects are managed within a hierarchical structure by the management console;

creating a first policy associated with the selected infrastructure object;

presenting a plurality of selectable annotation categories for the selected infrastructure object, where different annotation categories are selectable for different infrastructure objects;

selecting an annotation category for the selected infrastructure object and assigning a value to the annotation category, where the annotation category uses a default annotation and a custom annotation for selectively generating an alert associated with the selected infrastructure object;

providing a duration for generating the alert when the first policy is violated;

assigning a threshold value for a counter tracking performance of a resource associated with the selected infrastructure object for triggering a first policy violation; and

setting an indicator for foregoing an alert associated with a second policy violation of a second policy associated with the selected infrastructure object, when the first policy is violated based on a counter value of the assigned counter.

2. The method of claim 1, wherein an alert is generated for the second policy violation, when the indicator to forego the alert is not set.

3. The method of claim 1, further comprising:

collecting performance data from the storage system associated with the selected infrastructure object and the selected annotation category; and

generating the alert when the first policy is violated based on the threshold value.

4. The method of claim 1, further comprising:

storing violation of the first policy in a data structure tracking historical policy violations.

5. The method of claim 1, wherein the logical selected infrastructure object represents one of a storage volume, a storage device, a storage array, a storage pool and a virtual machine.

6. The method of claim 5, wherein the storage system maintains a plurality of counters to track performance data for the selected infrastructure object and the management console obtains the performance data only associated with the first policy.

7. The method of claim 1, wherein the first policy is generated using a graphical user interface presented on a display device by the management console.

8. A non-transitory, machine-readable storage medium having stored thereon instructions for performing a method, comprising machine executable code which when executed by at least one machine, causes the machine to:

represent by a management console a plurality of resources of a networked storage system with a plurality of infrastructure objects, the plurality of resources used for storing and retrieving data at and from a plurality of storage devices, where each of the plurality of infrastructure objects is associated with a performance counter to monitor resource performance for executing client requests for storing and retrieving data;

select an infrastructure object from among the plurality of infrastructure objects, where the plurality of infrastructure objects are managed within a hierarchical structure by the management console;

create a first policy associated with the selected infrastructure object;

present a plurality of selectable annotation categories for the selected infrastructure object, where different annotation categories are selectable for different infrastructure objects;

select an annotation category for the selected infrastructure object and assigning a value to the annotation category, where the annotation category uses a default annotation and a custom annotation for selectively generating an alert associated with the selected infrastructure object;

provide a duration for generating the alert when the first policy is violated;

assign a threshold value for a counter tracking performance of a resource associated with the selected infrastructure object for triggering a first policy violation; and

set an indicator for foregoing an alert associated with a second policy violation of a second policy associated with the selected infrastructure object, when the first policy is violated based on a counter value of the assigned counter.

9. The storage medium of claim 8, wherein an alert is generated for the second policy violation, when the indicator to forego the alert is not set.

10. The storage medium of claim 8, wherein the machine executable code further causes the machine to:

collect performance data from the storage system associated with the selected infrastructure object and the selected annotation category; and

generate the alert when the first policy is violated based on the threshold value.

11. The storage medium of claim 8, wherein the machine executable code further causes the machine to:

store violation of the first policy in a data structure tracking historical policy violations.

12. The storage medium of claim 8, wherein the selected infrastructure object represents one of a storage volume, a storage device, a storage array, a storage pool and a virtual machine.

13. The storage medium of claim 12, wherein the storage system maintains a plurality of counters to track performance data for the selected infrastructure object and the management console obtains the performance data only associated with the first policy.

14. The storage medium of claim 8, wherein the first policy is generated using a graphical user interface presented on a display device by the management console.

15. A machine implemented method, comprising:

representing by a management console a plurality of resources of a networked storage system with a plurality of infrastructure objects, the plurality of resources used for storing and retrieving data at and from a plurality of storage devices, where each of the plurality of infrastructure objects is associated with a performance counter to monitor resource performance for executing client requests for storing and retrieving data;

selecting an infrastructure object from among the plurality of infrastructure objects, where the plurality of infrastructure objects are managed within a hierarchical structure by the management console;

creating a first policy associated with the selected infrastructure object;

presenting a plurality of selectable annotation categories for the selected infrastructure object, where different annotation categories are selectable for different infrastructure objects;

selecting an annotation category for the selected infrastructure object and assigning a value to the annotation category, where the annotation category uses a default annotation and a custom annotation for selectively generating an alert associated with the selected infrastructure object;

providing a duration for generating the alert when the first policy is violated;

assigning a threshold value for a counter tracking performance of a resource associated with the selected infrastructure object for triggering a first policy violation;

setting an indicator for foregoing an alert associated with a second policy violation of a second policy associated with the selected infrastructure object, when the first policy is violated based on a counter value of the assigned counter;

collecting performance data from the storage system associated with the selected infrastructure object and the selected annotation category;

generating the alert when the first policy is violated based on the threshold value without generating any alert for the second policy violation; and

storing violation of the first policy in a data structure used for tracking historical policy violations.

16. The method of claim 15, wherein an alert is generated for the second policy violation, when the indicator to forego the alert is not set.

17. The method of claim 15, wherein the logical selected infrastructure object represents one of a storage volume, a storage device, a storage array, a storage pool and a virtual machine.

18. The method of claim 15, wherein the storage system maintains a plurality of counters to track performance data for the selected infrastructure object and the management console obtains the performance data only associated with the first policy.
