Daily Usage Report

The Daily Usage Report breaks down system resource utilization by user. A sample of this report follows:

The following table describes the data provided by the Daily Usage Report.

Table 10–3 Daily Usage Report Data


Column	Description
`UID`	User ID number.
`LOGIN NAME`	Login (or user) name of the user. Identifies a user who has multiple login names.
`CPU (MINS)`	Amount of time, in minutes, that the user's process used the central processing unit. Divided into `PRIME` and `NPRIME` (nonprime) utilization. The accounting system's version of this data is located in the `/etc/acct/holidays` file.
`KCORE-MINS`	A cumulative measure of the amount of memory in Kbyte segments per minute that a process uses while running. Divided into `PRIME` and `NPRIME` utilization.
`CONNECT (MINS)`	Amount of time, in minutes, that the a user was logged in to the system, or “real time.” Divided into `PRIME` and `NPRIME` utilization. If these numbers are high while the `# OF PROCS` is low, you can conclude that the user logs in first thing in the morning and hardly touches the terminal the rest of the day.
`DISK BLOCKS`	Output from the `acctdusg` program, which runs the disk accounting programs and merges the accounting records (`daytacct`). For accounting purposes, a block is 512 bytes.
`# OF PROCS`	Number of processes invoked by the user. If large numbers appear, a user might have a shell procedure that has run out of control.
`# OF SESS`	Number of times that a user logged in to the system.
`# DISK SAMPLES`	Number of times that disk accounting was run to obtain the average number of `DISK BLOCKS`.
`FEE`	Often unused field that represents the total accumulation of units charged against the user by the `chargefee` script.
