47.5 million lines over 7 days on about dozen LPARs. 6.78 millions lines per day. That is if no buggy programs are writing noisy messages to it or our TCP/IP printing systems are not complaining too much about dead printers. As it is now, 10:00 nearly all our LPARs have about +/- 500 000 lines since midnight. >Why am I curious? From a previous thread on doing a "tail -f" on the z/OS >SYSLOG.

We use an automation package to 'W X' the SYSLOG every day at 23:30 and keep it on DASD for 7 days and move it to archives. Due to high overhead, I ran scheduled SDSF in batch with command 'LOG' every 4 hours on all LPARs, so when my TSO users try to use SYSLOG on SDSF, they don't have to wait gazillion years for feedback from SYSLOG command. Did I SPOOLed too many messages on IBM-MAIN syslog? ;-D Groete / Greetings Elardus Engelbrecht ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
