What you need to know about your disk space but were afraid to ask
Robot/SPACE helps you manage your disk space. This article covers some common questions users have and how Robot/SPACE helps you answer them.
Can I tell which job is using my temporary storage?
Robot/SPACE has a monitor job (SPCJTSMON) that monitors job temporary storage. You set the thresholds for both logging and notification. To view all jobs that have exceeded the thresholds, right-click on the Job Temporary Storage Monitor from the Robot/SPACE Explorer and select Threshold History. You can sort the data by Date/Time, Peak Temporary Storage Used, Job Name, and so on.
How do I tell which user profile is responsible for using the most disk space?
The easiest way to find out who is using the most disk space is to display a graph using the Graphs/Trends feature. Right-click on Graphs/Trends and select Display. Select a collection group for the data and choose how to summarize it. Choose Summarize Total Size By Owner to view a pie chart showing the profiles using the most disk space.

Tip: Float your cursor over any piece of the pie chart to display the total amound of disk space used by that profile.
How can I determine where the disk space has gone?
Use the Critical Storage Investigator (CSI). The CSI uses a logical progression to find the source of disk space problems.
1. Open the Critical Storage Investigator by selecting its icon in the toolbar menu. The CSI displays overall ASP utilization levels and any sudden growth.
2. View job temporary storage to see if an out-of-control job is consuming your temporary storage and causing a sudden increase in ASP usage.
3. Review collection statistics to see whether a library or IFS directory has grown more than expected.
4. Run a collection group for current object size statistics.
5. If you haven’t found the problem, run the System Health report. This report lists every system object that has grown by the amount you specify and allows you to pinpoint unusual object growth. It summarizes each library by listing the current size, previous size, previous date, percentage change, and size change.
Can I be notified if an iASP or ASP has grown too quickly?
Robot/SPACE has an ASP monitor job (SPCASPMON) that runs in the RBTSLEEPER subsystem and continually checks ASP and iASP growth. If any thresholds are reached, Robot/ALERT can notify you by sending a message to an e-mail address, cell phone, PDA, or other device. Robot/SPACE can also send a message to a message queue, or send a Robot/NETWORK status message. You can monitor up to three different ASP percent usage thresholds, a growth rate threshold (such as ASP usage grew 15% over the last hour), and unprotected storage use.
Do I have any large unused *SAVF objects?
Robot/SPACE has a storage audit task to delete unused save files. Right-click in the Storage Audit section to add a storage audit. Select the tasks button and select “Delete unused save files.”
Or, you can print the results of the storage audit instead of actually deleting the unused save files. To do this, make sure the “Corrective Action” check box is set to None and the check box to print results from this audit task is selected.
How can I easily copy library statistical data to Excel?
Right-click on a collection to view Collection History. Select the date for which want statistical data and click on the Libraries section. The right panel displays detailed library information. Right-click on the library data and choose Select All. Right-click again and select Copy to Clipboard. You can keep the labels, or not, and paste the results into a blank Excel spreadsheet!
