Abstract

In one embodiment there is a system and method for harvesting data from at least one device, such that there is stored on a particular device, prior to the start of each harvesting session, an application program, which enables the harvesting of certain data from the device. At the conclusion of a harvesting session, the application program is removed from the device. In one embodiment the application is in the form of a chailet.

Claims

1. A method for harvesting data from at least one device, said method comprising:

storing on said at least one device an application program, said storing occurring prior to the start of a harvesting session, wherein said application program is a chailet including code interpreting between JAVA Virtual Machine and SNMP;

enabling said stored application program to harvest certain data front said at least one device;

prior to said storing step, determining if said certain data is obtainable from SNMP;

inhibiting said storing and enabling steps if it is determined that said certain data is obtainable from SNMP, and obtaining said certain data using SNMP;

communicating said harvested data to an application common to said least one device; and

removing said stored application program from said at least one device at the conclusion of said communicating step.

2. The method of claim 1 further comprising:

if it is determined that said certain data is not obtainable from SNMP, then determining if said at least one device supports JVM.

3. The method of claim 1 wherein said common application is the SNMP application.

4. The method of claim 1 wherein said at least one device is a printer.

5. The method of claim 1 further comprising:

repeating said storing, enabling, communicating and removing steps for said at least one device; and

storing harvested data in a database in relationship to said at least one device from which said harvested data was communicated.

6. The method of claim 5 further including:

transmitting said stored harvested data to a processing center.

7. The method of claim 6 wherein said transmitting step occurs only when data has been harvested from a plurality of said at least one devices.

8. A system for harvesting data from at least one device, said system comprising:

means for storing within said at least one device a chailet sent from a source external to said at least one device, wherein said chailet includes code interpreting between JAVA Virtual Machine and SNMP

means, including said stored chailet, for harvesting certain data from said at least one device;

means, operable if said certain data from said at least one device is obtainable from SNMP, for inhibiting said storing means and said means, including said stored chailet, for harvesting certain data, and harvesting said certain data using SNMP instead of the chailet;

means for communicating said harvested data to a database remote from said at least one device; and

means for removing said stored chailet from said at least one device at the conclusion of said harvesting of said certain data from said at least one device.

9. The system of claim 8 wherein said storing means includes at least a portion of a memory device resident within said at least one device, said memory device primarily used by said at least one device for tasks other than storing said chailet.

10. The system of claim 8 further comprising:

means for determining if said at least one device supports JVM and if said certain data is not obtainable from SNMP, for enabling said storing means with respect to said at least one device.

11. The system of claim 8 wherein said at least one device is a printer.

12. The system of claim 8 further comprising:

means for storing communicated certain data from said at least one device in a database in relationship to said at least one device from which said data was harvested.

13. The system of claim 12 further comprising:

means for transmitting said stored communicated data to a processing center.

14. The system of claim 13 wherein said transmitting means is only enabled when said certain data has been harvested from a particular group of said at least one devices.

15. The system of claim 8 wherein said storing means includes volatile memory resident within said at least one device.

16. A method of periodically harvesting data from at least one peripheral device containing limited volatile memory, said method comprising:

storing within said volatile memory a relatively small amount of code, wherein said code interprets between JAVA Virtual Machine and SNMP;

harvesting data from said at least one peripheral device, said harvesting facilitated by said stored code;

prior to said storing step, determining if said data is obtainable from SNMP;

inhibiting said storing and harvesting if it is determined that said data is obtainable from SNMP, and harvesting the data using SNMP instead of the small amount of code;

communicating said harvested data from said at least one peripheral device to a storage location; and

removing said code from said volatile memory on a periodic basis.

17. The method of claim 16 wherein said code is stored at the beginning of each harvesting session with respect to said at least one peripheral device and removed at the end of said harvesting session.
