ATSADC(1) local ATSADC(1) NAME
atsadc, atsa1, atsaftp, atsahttp -- counter-collection SYNOPSIS
atsadc [ t n ] [ ofile ] atsa1 [ t n ] atsaftp atsahttp DESCRIPTION
System activity-data can be gathered on special request of a user [see atsar(1) ] or automatically, on a routine basis, as described here. Usually the kernel maintains statistical counters that are incremented as various system actions occur. These include counters for CPU uti- lization, disk utilization, memory utilization and various network statistics. The program atsadc and the shell-script atsa1 are used to collect, save, and process these counters. The program atsadc (the data collector) samples system data n times with an interval of t seconds between samples, and writes in binary format to ofile or (default) to standard output. The sampling interval t should be greater than 1 second. If t and n are omitted, a special reset-record is written. This facility is used when booting to a multi-user state, to mark the time at which the counters restart from zero. For example, the reset-mark can be added to the daily data by the command: /usr/local/bin/atsadc /var/log/atsar/atsa`date +%d` Note that this entry is written to the /etc/rc.d/init.d/atsar file. The shell-script atsa1 is used to collect and store data in the binary file /var/log/atsar/atsadd where dd is the current day of the month. The arguments t and n cause records to be written n times at an interval of t seconds, or once if omitted. Furthermore this script takes care that log-files older than a week are removed once a day. A file containing following entries should be added to the /etc/cron.d directory to produce records every 20 minutes during working hours and hourly otherwise: 0 * * * 0-6 root /usr/local/bin/atsa1 20,40 8-17 * * 1-5 root /usr/local/bin/atsa1 See crontab(1) for details. The shell-script atsaftp counts the new transfers registered in the FTP-logfile(s) since the previous time this script was activated; the new counters are stored in the /var/log/atsar/ftpstat file in ASCII-format. The names of the FTP-logfiles to be watched are specified in the /etc/atsar.conf configuration-file. The shell-script atsahttp counts the new transfers registered in the HTTP-logfile(s) since the previous time this script was activated; the new counters are stored in the /var/log/atsar/httpstat file in ASCII-format. The names of the HTTP-logfiles to be watched are specified in the /etc/atsar.conf configuration-file. Both scripts must be activated just before the program atsadc is started, which also collects these counters. FILES
