Storage quota reports provide a summarized view of the past or present state of the quota domains. After raw reporting data is collected by OneFS, you can produce data summaries by using a set of filtering parameters and sort types. Storage-quota reports include information about violators, grouped by threshold types. You can generate reports from a historical data sample or from current data. In either case, the reports are views of usage data at a given time. OneFS does not provide reports on data aggregated over time, such as trending reports, but you can use raw data to analyze trends. There is no configuration limit on the number of reports other than the space needed to store them.
OneFS provides the following data-collection and reporting methods:
- Scheduled reports are generated and saved on a regular interval.
- Ad hoc reports are generated and saved at the request of the user.
- Live reports are generated for immediate and temporary viewing.
Scheduled reports are placed by default in the /ifs/.isilon/smartquotas/reports directory, but the location is configurable to any directory under /ifs. Each generated report includes quota domain definition, state, usage, and global configuration settings. By default, ten reports are kept at a time, and older reports are purged. You can create ad hoc reports at any time to view the current state of the storage quotas system. These live reports can be saved manually. Ad hoc reports are saved to a location that is separate from scheduled reports to avoid skewing the timed-report sets.
