Storage

Whenever AFA generates a report, the report is stored on the AFA server. Each AFA report may consume significant amounts of storage (about 75 MB* per report on average, though this can greatly vary). For example, if you have four devices whose policies are changed and analyzed daily, then AFA reports will consume about 4x75 = 300 MB per day, 7x4x75 = 2.1 GB per week. Therefore, you would require an empty 150 GB disk in order to store 70 weeks worth of reports. For more details, see System requirements.

To enable you to efficiently manage your available disk space, and to prevent an overload of data on the AFA server, you can configure AFA to delete old reports, based on deletion criteria you define. You can configure clean-up to run automatically or trigger it manually, as needed.

Note: AFA checks the amount of local disk space remaining after running each report. If the remaining space is less than 10 GB, or if more than 95% of the disk is already used, AFA sends a warning e-mail to the users configured to receive error messages via e-mail notifications. See Configuring Event-Triggered Notifications (see Configure event-triggered notifications). In addition, AFA also sends notifications via the issues center and Syslog messages. For details, see Manage ASMS issues and AFA Syslog messages.

Note: AFA provides an option to only run a scheduled analysis if policy changes were detected since the previous analysis. This option ensures that full analyses will only run when the report will differ from the most recent report, saving both the CPU time needed to produce a report and the disk space needed to store it. To enable this option, select the Run analysis only when policy is changed check box, in the General sub-tab of the Options tab in the Administration area. For more details, see Define AFA preferences.

Note: You can optionally save reports on your remote backup server by including reports in your ASMS backups. See the Backup/Restore (see Backup/Restore) tab.

Configure report cleanup

Do the following:

  1. In the toolbar, click your username.

    A drop-down menu appears.

  2. Select Administration.

    The Administration page appears, displaying the Options tab.

  3. Click Storage.

    The Storage tab appears.

  4. Complete the fields using the information in Storage Fields (see Storage Fields).

  5. Click OK.

    If the number of days to retain reports is greater than the number of days to retain the monitoring information, a confirmation message appears.

    Click OK.

    The settings are changed.

  6. To delete any reports that meet the deletion criteria immediately, rather than wait until the next scheduled clean-up time, do the following:

  7. Click Clean-up now.

    A success message appears.

  8. Click OK.
