Abstract

A library of performance monitor recordings is maintained according to pathologies. The library is indexed to provide a facility to diagnosis poorly performing data processing systems, by capturing performance statistics and comparing these statistics against known problematic statistics. Remote diagnosis can easily be provided by a user capturing a performance session, saving to a file, and transferring the file to a central facility for comparison against its pathological libraries.

Claims

1. A method, in a network having a plurality of data processing systems, of allowing a user to graphically determine performance diagnostics for at least one of said data processing systems said method comprising the steps of:

creating, for a first one of said data processing systems, a console window having at least one instrument window, said at least one instrument window having an instrument graphical context, and said console window having a console graphical context;

generating time sampled values from at least one statistic for a second one of said data processing systems;

graphically displaying on said first data processing system, using said console window, said time sampled values according to said instrument graphical context;

storing, during said displaying, said console window and said time sampled values;

retrieving said stored console window and said stored time sampled values; and

graphically displaying on said first data processing system, with said retrieved console window, said retrieved time sampled values using said retrieved instrument graphical context so that said retrieved time sampled values appear as live data.

2. The method of claim 1 further comprising the step of:

creating a data supplier daemon for providing said time sampled values from said second data processing system.

3. The method of claim 2 further comprising the step of:

designating said at least one instrument window for displaying said time sampled values.

4. The method of claim 2 wherein said step of graphically displaying on said first data processing system, with said retrieved console window is performed at an increased rate for said time sampled values.

5. The method of claim 2 wherein said step of graphically displaying on said first data processing system, with said retrieved console window is performed at a decreased rate for said retrieved time sampled values.

6. The method of claim 2 wherein said console window graphical context includes position, size, type, and name, and said instrument graphical context includes position, size, type, presentation style, and name.

7. The method of claim 6 wherein said step of graphically displaying on said first data processing system, using said console window, includes the step of:

graphically displaying on said first data processing system, using said console window, said time sampled values according to said presentation style.

8. The method of claim 7 wherein said step of graphically displaying on said first data processing system, with said retrieved console window, includes the step of:

graphically displaying on said first data processing system, with said retrieved console window, said retrieved time sampled values according to said presentation style.

9. The method of claim 7 further comprising the step of:

dynamically changing said presentation style during said displaying of said time sampled values.

10. A method, in a network having a plurality of data processing systems, of allowing a user to graphically determine performance diagnostics for at least one of said data processing systems, said method comprising the steps of:

maintaining a library of stored console windows and a plurality of stored sets of time sampled values for statistics reflecting defective conditions occurring on a data processing system, each one of said stored console windows having a console graphic context and at least one instrument window having an instrument graphic context;

receiving notification of a defective condition occurring on a first one of said data processing systems;

creating, in a second one of said data processing systems, a first console window having at least one instrument window, said at least one instrument window having an instrument graphical context, and said first console window having a console graphical context;

graphically displaying on said second data processing system, using said first console window, a set of live time stamped values for at least one statistic associated with said defective condition, said set of live time stamped values being displayed according to said instrument graphical context of said second one of said data processing systems;

retrieving one of said stored console windows, having at least one instrument window, and one of said stored plurality of sets of time sampled values from said library; and

graphically displaying on said second data processing system, with said retrieved console window, said retrieved one of said stored plurality of sets of time sampled values according to said retrieved at least one instrument graphical context, thereby allowing a user to graphically correlate said first, console window and said retrieved console window, to diagnose said defective condition.

11. An apparatus for allowing a user to graphically determine performance diagnostics for at least one of a plurality of data processing systems in a network, said apparatus comprising:

means for maintaining a library of stored console windows and a plurality of stored sets of time sampled values for statistics reflecting defective conditions occurring on a data processing system, each one of said stored console windows having a console graphic context and at least one instrument window having an instrument graphic context;
