Abstract A system resource monitor is provided to capture a data processing system's internal resource utilization, such as memory, CPU, or peripheral device availability/utilization. The captured 'state' of the data processing system's resources is maintained in real-time, while the impact on the system's performance in providing such information is kept to a minimum. This is accomplished through a combination of various techniques, including specialized device drivers for the respective devices coupled with a unique data reduction technique. Such techniques include filtering only events which are of interest and combining similarly related events to reduce data processing requirements. This real-time support provides an immediate and accurate representation of the internal operations of the data processing system. Further, these resources can monitored at the process level of a multiprocessing system. This captured data can be used by an application or control program to identify, isolate, and fine-tune the data processing system's resources to improve the overall efficiency of the system being monitored.
A method for capturing and reducing resource data in real time in a data processing system, comprising the steps of: receiving resource events generated by a data processing system; determining, based upon said resource event, whether to filter or pass said resource event; and processing said passed resource events and combining similarly related of said resource events into a single event.
Claim 2
Dependent Claim
11 words
The method of Claim 1 wherein said resource events are bi-modal.
Claim 3
Dependent Claim
20 words
The method of Claim 1 further comprising the step of including at least one timestamp value to said single event.
Claim 4
Independent Claim
33 words
A method as claimed in any preceding claim for capturing and reducing resource data in a multiprocessing system, wherein said single event represents corresponding pre-hook and post-hook events occurring in said multiprocessing system.
Claim 5
Dependent Claim
15 words
The method of Claim 4 wherein said single event represents a plurality of interrupt events.
Claim 6
Dependent Claim
16 words
The method of Claim 4 wherein filtering or passing said resource event has process level granularity.
Claim 7
Dependent Claim
20 words
The method of Claim 6 further comprising the step of including at least one timestamp value to said single event.
Claim 8
Independent Claim
70 words
A system for capturing and reducing resource data in real time in a data processing system, comprising: receiving means for receiving multiprocess resource events generated by a data processing system; determining means for determining, based upon said mulitiprocess resource event, whether to filter or pass said multiprocess resource event; and processing means for processing passed multiprocess resource events to combine similarly related of said resource events into a single event.
Claim 9
Dependent Claim
20 words
The system of Claim 8 further comprising including means for including at least one timestamp value to said single event.
Claim 10
Dependent Claim
15 words
The system of Claim 8 wherein said single event represents corresponding pre-hook and post-hook events.
Claim 11
Dependent Claim
15 words
The system of Claim 8 wherein said single event represents a plurality of interrupt events.
Claim 12
Dependent Claim
13 words
The system of Claim 8 wherein said resource event has process level granularity.
Claim 13
Dependent Claim
20 words
The system of Claim 12 further comprising including means for including at least one timestamp value to said single event.
