Daily Command Summary

The daily command summary report shows the system resource utilization by command. With this report, you can identify the most heavily used commands and, based on how those commands use system resources, gain insight on how to best tune the system. The daily command and monthly reports are virtually the same except that the daily command summary reports only on the current accounting period while the monthly total command summary reflects the data accumulated since the last invocation of monacct.

These reports are sorted by TOTAL KCOREMIN, which is helpful for calculating ``drain'' on a system.

``Sample Daily Command Summary'' shows a sample daily command summary.

Sample Daily Command Summary

The data provided includes the following:

COMMAND NAME

The name of the command. All shell procedures are lumped together under the name sh because only object modules are reported by the process accounting system. Monitor the frequency with which you see program names such as a.out, core, or any other name that does not seem right. By doing so, you may spot programs written for private use (such as someone's favorite version of online backgammon) hidden behind innocuous names. acctcom also helps determine who executed a suspiciously named command and whether it was executed with the UID or GID set to root.

NUMBER CMDS

The total number of invocations of this particular command.

TOTAL KCOREMIN

The total cumulative measurement of the amount of kilobyte segments of memory used by a process per minute of run time.

TOTAL CPU-MIN

The total processing time this program has accumulated.

TOTAL REAL-MIN

Total real-time (wall-clock) minutes this program has accumulated.

MEAN SIZE-K

The mean of the TOTAL KCOREMIN over the number of invocations reflected by NUMBER CMDS.

MEAN CPU-MIN

The mean derived between the NUMBER CMDS and TOTAL CPU-MIN.

HOG FACTOR

The ratio of system availability to system utilization, shown by the total CPU time divided by the elapsed time. This gives a relative measure of the total available CPU time consumed by the process during its execution.

CHARS TRNSFD

The total count of characters transferred by the read and write system calls. (Because of overflow, this number may be negative.)

BLOCKS READ

The total count of the physical block reads and writes performed by a process.
