6. Solaris
Hi,
I'm running a multi-process software system on a Solaris 8 machine. When I monitor the memory usage, I see that the free memory is dropping rapidly, but I can't detect a process that uses this memory.
I'm using "top" to get the free memory and the memory usage of processes.
Thanks. (3 Replies)

sa1(8) BSD System Manager's Manual sa1(8)
NAME
sa1 -- Generate a system activity daily data file.
SYNOPSIS
/usr/lib/sa/sa1 [t n]
DESCRIPTION
The sa1 command is a shell script used to invoke the system activity data collector, sadc. The binary sample data is collected at intervals
t seconds apart, in a loop n times. The binary sample data is written to the standard daily data file, /var/log/sa/sadd where the dd repre-
sents the current day of the month.
sa1 is intended to be started by cron.
EXAMPLE CRON ENTRY
# Starting at 8am collect system activity records
# every 20 minutes for 12 hours
# 20 minutes = 1200 seconds
# 12 hours with 3 samples each hour = 36 loops
0 8 * * 1-5 /usr/lib/sa/sa1 1200 36
# After the 12 hour period,
# collect a system activity report
30 20 * * 1-5 /usr/lib/sa/sa2 -A
FILES
/var/log/sa/sadd Default daily activity file that holds the binary sampling data. dd are digits that represent the day of the month.
