Bar chart showing the total number of STA alerts for drives, media, libraries, CAPs, and PTPs generated over a selected date range.

Alerts are generated based on user-defined alert policies. Because the number of alert policies and their criteria and severity are entirely user-defined, this graph does not necessarily indicate issues with your tape library system environment.

Line graph showing the total number and severity of STA alerts each day over a selected date range.

Alerts are generated based on user-defined alert policies. Because the number of alert policies and their criteria and severity are entirely user-defined, this graph does not necessarily indicate issues with your tape library system environment.

Line graph showing the total amount of data read and written over a selected date range.

Area chart showing, by drive model, the total number of dismounts each day over a selected date range.

Bar chart showing, by drive model, the total number of drives with each Drive Health Indicator as computed by STA.

Line graph showing, by drive model, the average Drive Suspicion Level each day over a selected date range.

To compute the daily value for a given model, STA averages the suspicion levels of all installed drives of that model, regardless of how many were actually used that day. If a drive was not used on a given day, its suspicion level is carried forward from the day before.

Line graph showing the average percentage of time the drives were occupied each hour, day, week, or month. You can filter by drive location (complex, library, or rail, for example) and by date range.

Values shown in this pane are updated at the end of each hour, so are not real-time.

Line graph showing the total amount of data read and written each hour, day, week, or month over a selected date range.

Line graph showing, by library component type (robots, CAPs, elevators, and pass‐through ports), the average daily condition over a selected date range.

The conditions are as reported by the library, not by STA.

Bar chart showing, by library component type (robots, CAPs, elevators and pass‐through ports), the current total number of components with each reported condition.

The conditions are as reported by the library, not by STA.

Pie chart showing the current distribution of installed drives by type and empty drive slots.

Pie chart showing the current distribution of occupied media slots by media type and empty slots.

Bar chart showing, by library model, the current total number of libraries with each Top-Level Indicator as reported by the library.

Line graph showing, for each hour, day, week, or month over a selected date range, the total time-to-mount of the single exchange that took the longest time to mount. The value plotted is the total time from the start of the exchange to the start of the mount.

Line graph showing, for each hour, day, week, or month over a selected date range, the piece of media with the longest time since the last exchange. The value plotted is the total time since the last exchange. Only media that have had exchange activity are included.

Values shown in this pane are updated at the end of each hour, so are not real-time.

Bar chart showing, by media type, the total number of media with each Media Health Indicator as computed by STA.

Line graph showing, by media type, the average Media Suspicion Level each day over a selected date range.

To compute the daily value for a given media type, STA averages the suspicion levels of all available media of that type, regardless of how many were actually used that day. If a media was not used on a given day, its suspicion level is carried forward from the day before.

Line graph showing the total times media were entered, ejected, or otherwise moved each hour, day, week, or month over a selected date range. "Other" movements include moves by robots, elevators, or PTPs.

Values shown in this pane are updated at the end of each hour, so are not real-time.

Line graph showing the minimum and maximum media slots available each hour, day, week, or month over a selected date range

Line graph showing an estimate of average media utilization each hour, day, week, or month over a selected date range. Media utilization is the percentage of the total media capacity that has been used by data—that is, the "fullness" of the media. Only media that have had exchange activity are included.

Values shown in this pane are updated at the end of each hour, so are not real-time.

Line graph showing an estimate of the number of media bands, or utilization ranges, used each hour, day, week, or month over a selected date range. A band appears on the graph only if there are media with utilization values in that range.

The <0001% band includes both media that is literally blank and media that is effectively blank because it has an internal label but no real data.

Values shown in this pane are updated at the end of each hour, so are not real-time.

Line graph showing the total number of media validations, and the total passed, failed, and unknown for the selected time period.

Line graph showing the total number of mounts each hour, day, week, or month over a selected date range. The value plotted is the number of mounts, not dismounts.

Bar chart showing the current number of robots by Robot Health as computed by STA.

Bar chart summarizing the total number of rails on which a media travels to complete a dismount request as part of an exchange. This includes movements by robots, elevators, and PTPs. If a media crosses a rail without stopping, the rail is not included in the count. For example:

• For a media moved from a drive to a media slot on the same rail, the count is "1."

• For a media moved from a drive on rail #4 to a media slot on rail #1, the count is "2."

• For a media moved from a drive on rail #4, to a PTP on rail #3, to a drive on rail #1 in a different library, the count is "3."

For libraries managed by StorageTek ACSLS, if the media float option is enabled, dismount move efficiency will be "1" whenever media slots are available within the same LSM as the drive.

• For a media moved from a media slot on rail #1 to a drive on rail #4, the count is "2."
• For a media moved from a drive on rail #1, to a PTP on rail #3, to a drive on rail #4 in a different library, the count is "3."
