wherein the extraction-result recording portion is configured to output extract resultant data in such a manner that the specified pieces of log data having different recording formats are displayed on a screen at the same time or the specified fields that constitute the specified pieces of log data having different recording formats are displayed on the screen at the same time.

2. The information processing system according to claim 1 , wherein the log file comprises pieces of log data generated from a plurality of apparatuses and having different recording formats.

3. The information processing system according to claim 2 , wherein the pieces of log data having different recording formats are transmitted via a predetermined communication protocol, and recorded in the log file in an order in transmission.

4. The information processing system according to claim 2 , wherein the pieces of log data having different recording formats are transmitted via a network, and recorded in the log file.

5. The information processing system according to claim 2 , wherein the plurality of apparatuses are made by different makers or vendors.

6. The information processing system according to claim 1 , further comprising an output portion including the screen and configured to output the specified pieces of log data extracted by the extraction processing portion or the specified fields that constitute the specified pieces of log data.

7. The information processing system according to claim 1 , further comprising a sort control portion configured to sort, by using a sort key, the specified pieces of log data extracted by the extraction processing portion or the specified fields that constitute the specified pieces of log data.

8. The information processing system according to claim 7 , wherein the sort key is time information at which each piece of the log data to be recorded in the log file is received via a predetermined communication protocol, or time information included in a time stamp that is included in each piece of the log data.

9. The information processing system according to claim 1 , further comprising a work terminal that comprises a user interface configured to set the format information and/or the extraction condition.

10. The information processing system according to claim 9 , wherein the work terminal comprises an output portion including the screen and configured to output the specified piece of log data extracted by the extraction processing portion or the specified field that constitutes the specified piece of log data.

11. The information processing system according to claim 10 , wherein an output format in which a specified field is outputted is different from a format in which a specified piece of log data or the specified field is recorded.

12. The information processing system according to claim 9 , wherein the log file comprises the pieces of log data generated from a plurality of production apparatuses and having different recording formats.

13. The information processing system according to claim 12 , wherein the plurality of production apparatuses comprises a robot and/or a robot hand.

14. The information processing system according to claim 1 , wherein the extraction-result recording portion is configured to output extract resultant data in such a manner that the specified pieces of log data having different recording formats are displayed on the screen at the same time with time information at which each piece of the log data to be recorded in the log file or time information included in a time stamp that is included in each piece of the log data, or the specified fields that constitute the specified pieces of log data having different recording formats are displayed on the screen at the same time with the time information at which each piece of the log data to be recorded in the log file or the time information included in the time stamp that is included in each piece of the log data.

15. An information processing method that extracts specified pieces of log data or specified fields that constitute the specified pieces of log data, from a log file in which pieces of log data having different recording formats are mixed, the information processing method comprising:

preparing, by a control device, format information in which determination conditions to identify recording formats of the specified pieces of log data are contained;

preparing, by the control device, an extraction condition to extract the specified pieces of log data or the specified fields that constitute the specified pieces of log data;

extracting, by the control device, the specified pieces of log data having different recording formats or the fields that constitute the specified pieces of log data having different recording formats, from the log file by using the format information and the extraction condition; and

outputting, by the control device, extract resultant data in such a manner that the specified pieces of log data having different recording formats are displayed on a screen at the same time or the specified fields that constitute the specified pieces of log data having different recording formats are displayed on the screen at the same time.

16. A non-transitory machine readable storage medium storing a program that causes a computer to perform the information processing method according to claim 15 .
