Image forming system and image forming apparatus
An image forming system for obtaining a counter value of a requested event comprises an image forming apparatus storing counter reference sequence data and counter values and a terminal apparatus specifying event types for the counter values using the counter reference sequence data and obtaining the counter value of the requested event type.
1. An image forming system comprising:
an image forming apparatus comprising
a counter configured to count a number of event occurrences in the image forming apparatus;
a data storage device in communication with the counter and configured to store the number of event occurrences as counter data and counter reference sequence data, wherein the counter data includes a plurality of counter values corresponding to a plurality of event types and wherein the counter reference sequence data includes a plurality of counter IDs indicating to which of the plurality of event types the counter values correspond, wherein the counter data is stored as a single Management Information Base (MIB) object and the counter reference sequence data is stored as a single MIB object; and
a first communication processor configured to communicate the counter data and the counter reference sequence data with a terminal apparatus via a Simple Network Management Protocol (SNMP); and
a terminal apparatus comprising:
a second communication processor configured to receive the counter data and the counter reference sequence data from the image forming apparatus, wherein the second communication processor is configured to obtain the counter data from the image forming apparatus by a single transmission of an SNMP command and the second communication processor is configured to obtain the counter reference sequence data from the image forming apparatus by a single transmission of an SNMP command; and
a counter value obtaining unit configured to specify the event type of each of the counter values in the counter data obtained by the single transmission of the SNMP command on the basis of a value of each of elements in the counter reference sequence data and obtain the counter value of the requested event type,
wherein the counter IDs of the counter reference sequence data identify one of the plurality of event types as corresponding to one of the plurality of counter values having an index value that is the same as an index value of the counter ID.
2. The image forming system according to claim 1 , wherein the counter value obtaining unit comprises a utility.
3. The image forming system according to claim 2 further comprising a computer in the terminal apparatus configured to execute a program to implement the utility.
4. The image forming system according to claim 1 , wherein the SNMP command comprises a SNMPGET command for obtaining an SNMP object specified by an object identifier (OID).
5. The image forming system according to claim 4 , wherein each of the SNMP commands comprises a SNMPGet command for obtaining an SNMP object specified by an OID.
6. The image forming system according to claim 1 , wherein the image forming apparatus further comprises a printing device, an image reading device, and/or a facsimile device.
7. The image forming system according to claim 1 , wherein the counter reference sequence data comprises reference information corresponding to the counter values.
8. The image forming system according to claim 1 , wherein the counter data comprises sequence data.
9. An image forming apparatus comprising:
a counter configured to count a number of event occurrences in the image forming apparatus;
a data storage device in communication with the counter and configured to store the number of event occurrences as counter data and counter reference sequence data, the counter data being stored as a single Management Information Base (MIB) object and the counter reference sequence data being stored as a single MIB object, wherein the counter data includes a plurality of counter values corresponding to a plurality of event types and wherein the counter reference sequence data includes a plurality of counter IDs indicating to which of the plurality of event types the counter values correspond; and
a communication processor configured to communicate the counter data and the counter reference sequence data with a terminal apparatus via a Simple Network Management Protocol (SNMP), wherein the communication processor is configured to transmit the counter data by a single transmission of an SNMP command, and the communication processor is configured to transmit the counter reference sequence data by a single transmission of an SNMP command;
wherein the counter IDs of the counter reference sequence data identify one of the plurality of event types as corresponding to one of the plurality of counter values of having an index value that is the same as an index value of the counter ID.
10. The image forming apparatus according to claim 9 , wherein the counter data comprises sequence data.
11. The image forming apparatus according to claim 9 , further comprising a printing device, an image reading device, and/or a facsimile device.
12. The image forming apparatus according to claim 9 , wherein the event types comprise a printing event, an image reading event, and/or a facsimile event.
13. The image forming apparatus according to claim 9 , wherein the counter reference sequence data further comprises reference information corresponding to the counter values.
14. The image forming apparatus according to claim 9 , wherein the data storage device is further configured to store counter attribute data in association with the counter reference sequence data.
15. The image forming apparatus according to claim 14 , wherein counter attribute data comprises a counter name and restriction information that are associated with at least one of the plurality of counter IDs.
