Abstract

A system management tool provides a comprehensive summary of operational information of a storage system. For example, the system management tool presents a digital dashboard (“dashboard”) in a graphical user interface. The system management tool also presents, via the dashboard, views that correspond to different dimensions of the storage system. In response to expansion of a selected view, the system management tool can automatically collapse the other views into a non-expanded views or move the other views to visible areas remaining after expansion of the selected view. Thus, all of the views remain continuously visible via the dashboard despite the modification to the appearance of the selected view.

Claims

1. A method comprising:

collecting, at a memory of a computing device having a processor, operational information about a storage system coupled to the computing device;

presenting, in a graphical user interface (GUI) rendered on a display coupled to the computing device, a digital dashboard presenting the collected operational information by category according to a plurality of views, wherein each of the plurality of views includes a different category of the collected operational information;

displaying, on the digital dashboard, a first view of the plurality of views as an expanded view and a second view of the plurality of views as a non-expanded view, wherein the expanded view includes a different level of detail from the non-expanded view, wherein a collection rate of the collected operational information for the expanded view differs from the collection rate of the collected operational information for the non-expanded view; and

in response to detecting a trigger to expand the non-expanded view, managing presentation of the collected operational information rendered on the display by collapsing the expanded view and rearranging a remaining plurality of views so as to maintain display of all categories of the collected operational information on the dashboard.

2. The method of claim 1 further comprising:

in response to detecting the trigger to expand the non-expanded view, resizing a horizontal dimension of the expanded view of the plurality of views, the expanded view depicted as a timeline graph of the collected operational information; and

reducing a time period of the timeline graph so as to display less of the collected operational information as depicted in the expanded view.

3. The method of claim 1 further comprising:

in response to determining that a value of the collected operational information for a first category exceeds a threshold, displaying in a third view of the plurality of views associated with the first category, an indicator at an initial intensity; and

causing the indicator to fade in intensity over a period of time, after the indicator at the initial intensity is displayed, during which the collected operational information for the first category is below the threshold.

4. The method of claim 1 further comprising:

modifying a refresh rate for the display of the collected operational information for a third view of the plurality of views in proportion to a degree that a value of the collected operational information of the third view approaches a threshold.

5. The method of claim 1 further comprising:

in response to a mouse over trigger event for a first category of the collected operational information of the non-expanded window, displaying an additional view as an overlay, wherein the overlay includes a timeline graph of the collected operational information for the first category.

6. The method of claim 1 further comprising:

performing analytics on a portion of the collected operational information;

predicting a potential failure of a component of the storage system based on the performance of the analytics; and

presenting, in a third view of the plurality of views associated with the component, an indicator of the potential failure.

7. The method of claim 1 wherein collecting further comprises:

caching the collected operational information in the memory, retrieving the displayed operational information from the cache; and

evicting the cached operational information from the memory in accordance with a sliding window of time.

8. The method of claim 1 further comprising:

updating each view of the plurality of views by a respective one of a plurality of independently executing threads on the processor, wherein each respective thread is capable of maintaining a different refresh rate for the collected operational information according to the category of the view.

9. The method of claim 1 wherein managing presentation of the collected operational information further comprises:

in response to the detecting the trigger to expand the non-expanded view, evaluating the trigger against an expansion rule set to determine whether the non-expanded view should be changed in size in response to the trigger.

10. The method of claim 1 further comprising:

synchronizing presentation of the collected operational information for each view of the plurality of views depicting a timeline graph.

11. The method of claim 1 further comprising:

in response to determining that a value of the collected operational information for a first category exceeds a first threshold, displaying in a third view of the plurality of views associated with the first category, a first indicator; and

in response to determining that the value of the collected operational information for the first category exceeds a second threshold, replacing display of the first indicator with a second indicator different from the first indicator.

12. An apparatus comprising:

a processor coupled to a memory;

a storage system coupled to the processor;

a display coupled to the processor; and

a machine-readable medium having program code stored thereon, the program code configured to;

collect operational information about the storage system;

present, in a graphical user interface (GUI) rendered on the display, a digital dashboard presenting the collected operational information by category according to a plurality of views, wherein each of the plurality of views includes a different category of the collected operational information;

display, on the digital dashboard, a first view of the plurality of views as an expanded view and a second view of the plurality of views as a non-expanded view, wherein the expanded view includes a different level of detail from the non-expanded view, wherein a collection rate of the collected operational information for the expanded view differs from the collection rate of the collected operational information of the non-expanded view; and

in response to a detecting a trigger to expand the non-expanded view, manage presentation of the collected operational information rendered on the display by collapsing the expanded view and rearranging a remaining plurality of views so as to maintain display of all categories of the collected operational information on the dashboard.

13. The apparatus of claim 12, wherein the machine-readable medium further has stored therein program code configured to in response to the trigger to expand the non-expanded view:

resize a horizontal dimension of the expanded view of the plurality of views, the expanded view depicted as a timeline graph; and

reduce a time period of the timeline graph so as to display less of the collected operational information.

14. The apparatus of claim 13, wherein the machine-readable medium further has stored therein program code executable by the processor configured to, in response to the trigger to expand the non-expanded view, update each of the plurality of views with the collected operational information.

15. The apparatus of claim 13, wherein the machine-readable medium further has stored therein program code configured to move at least one of the plurality of views that is expanded to a portion of the GUI rendered on the display appearing outside of the digital dashboard.

16. The apparatus of claim 13, wherein the machine-readable medium further has stored therein program code configured to, in response to the trigger to expand the non-expanded view, maintain a relative layout on the dashboard of the plurality of the views.

17. The apparatus of claim 12, wherein the machine-readable medium further has stored therein program code configured to:

provide the collected operational information for each category according to instructions of a set of application program interfaces (APIs) associated with a respective category, wherein the instructions of each API of the set of APIs correspond to a different level of detail of the collected operational information according to a state of expansion of the view associated with the respective category wherein the instructions of at least one API for each set of APIs query an operating system to collect the collected operational information, and wherein the operating system is configured to periodically access sensors of the storage system.
