Activities Report

Overall ACS Statistics - ACS Section of the Report

For the ACS section of the Activities report, ACS statistics are reported under the following report headings:

ACS ID

is the ACS number of the ACS being reported, the number of SMF records, and the earliest and latest SMF record date (mm/dd/yy or yyyymmdd) and time (hh:mm:ss) found matching the Activities Report verbs duration specification.

LSM

the LSM numbers are listed across the page.

ARM USE

is the mean percent LMU calculated LSM arm busy found in the SMF input matching the duration criteria.

The LMU calculates this value as the amount of time since start of an LMU interval the LSM arm has been in motion divided by the total time in the LMU interval. This value is then summed for all SMF records and divided by the number of SMF records found matching the duration criteria.

The value is reported as a percent and may range from 0 to 100 percent. A value of ‘‘N/A’’ indicates the LSM is not configured. A value of ‘‘X percent’’ indicates that the LSM is configured, but no SMF records matched the duration criteria.

LSM arm motion is used for CAP and audit scans as well as general cartridge movement. This does not include pass-thru port rotation time, but does include time to place the cartridge into the pass-thru port or to remove a cartridge from the pass-thru port.

P-THRU

is the LMU calculated number of master pass-thru operations found in the SMF records matching the duration criteria.

This is recorded by the LMU every LMU interval and is summed by the Activities Report.

The value is reported as a count of pass-thrus and can range from 0 to 99,999 pass-thrus. A value of ‘‘N/A’’ indicates the LSM is not configured. A value of ‘‘X’’ indicates that the LSM is configured, but no SMF records matched the duration criteria.

Each pass-thru port has both a master and a slave LSM. A pass-thru operation involves placing a cartridge into one side of a pass-thru port, rotating the pass-thru port, and removing the cartridge from the other side of the pass-thru port. Each pass-thru operation is counted one time and is only counted by the master side LSM for the pass-thru port.
