File check interval
The File Trigger function checks at regular intervals for the presence of files, time stamps, and size modifications, and determines whether creation, deletion, or modification of files has been carried out or not.
The timing of job execution for a check interval of 10 minutes is shown below.
The timing of job execution when monitoring for file creation is shown in the following figure.
Figure 2.50 File Creation Monitoring and Job Execution
The timing of job execution when monitoring for file deletion is shown in the following figure.
Figure 2.51 File Deletion Monitoring and Job Execution
The timing of job execution when monitoring for file modification is shown in the following figure.
Figure 2.52 File Modification Monitoring and Job Execution
The timing of job execution when monitoring for file creation and deletion is shown in the following figure.
Creation and deletion are detected only after monitoring starts, because monitoring is performed based on the file status at the time when monitoring started.
Figure 2.53 File Creation and Deletion Monitoring and Job Execution
The timing of job execution when monitoring for file creation and modification is shown in the following figure.
Figure 2.54 File Creation and Modification Monitoring and Job Execution
The timing of job execution when monitoring for file deletion and modification is shown in the following figure.
Figure 2.55 File Deletion and Modification Monitoring and Job Execution
The timing of job execution when monitoring for file creation, deletion, and modification is shown in the following figure.
Figure 2.56 File Creation, Deletion, and Modification Monitoring and Job Execution
The File Trigger function does not monitor the progress between one check and another, even if there are multiple changes in file status. It determines if there has been creation, deletion, or modification based on the file status immediately prior to the check.
Examples that illustrate cases where a performed operation is not detected are shown below.
When a file is deleted and re-created after the previous check
-
File creation is not detected, even if Monitor Creation is specified for the file.
-
File deletion is not detected, even if Monitor Deletion is specified for the file.
-
If Monitor Modification is specified for the file, it is detected as a modification to the file (if there is a modification to time stamp or file size).
Figure 2.57 Monitoring and Detection When File is Deleted and Re-created
When a file is modified and deleted after the previous check
-
File deletion is detected if Monitor Deletion is specified for the file.
-
File modification is not detected, even if Monitor Modification is specified for the file.
Figure 2.58 Monitoring and Detection When File is Modified and Deleted
When a file is created, modified, then deleted after the previous check
-
File creation is not detected, even if Monitor Creation is specified for the file.
-
File deletion is not detected, even if Monitor Deletion is specified for the file.
-
File modification is not detected, even if Monitor Modification is specified for the file.
