File System reports overview

File System reports include information about the files that are stored on a cluster.

The File System reports information includes the number of files that are stored on the cluster, the types of files that are stored on the cluster, and where files are located.

InsightIQ supports two kinds of File System Analytics reports: Data Usage reports and Data Property reports. Data Usage reports include data about the individual files on a cluster, such as which files have remained unchanged for the longest amount of time. Data Properties reports include data about the overall cluster file system, such as how many files were last changed during a specific period. Data Properties reports can also be compared between two different points in time. For example, you can view the relative changes in file count by physical size.

File System reports can be used to manage storage space among multiple clusters. For example, if you have two clusters, you can view the Data Properties report to compare file utilization. You can compare that the files are changed regularly on one cluster and that the files on the second cluster are modified occasionally. If the Data Properties report reveals that a significant number of files on the cluster have not been accessed in a long time, you can view the Data Usage report to identify the inactive files. To archive storage, consider transferring the inactive files.

You can use a File System report to verify that the file system of a cluster is behaving as expected. For example, if you have a cluster that is designated for archiving data, you can use the data properties report to view the file count by last changed file system module. This report shows you the last change date of the files on the cluster. If the count of files that have been changed is particularly high, you can consider moving those files to a cluster intended for development.

You can also use Files System reports to investigate files. For instance, if you discovered from a Performance report or the InsightIQ Dashboard that you had less capacity remaining than you expected, you can view the data usage File Systems report for that cluster. The Data Usage report includes a report module that can be customized to show the top 1000 largest files on the cluster. You could use this report to verify which files were taking up the most space on the cluster.
