I'm running mysql in a zone and wanted to look at the memory usage of
the db zone using prstat:
# prstat -t -z db
NPROC USERNAME SWAP RSS MEMORY TIME CPU
2 mysql 60M 48M 1.2% 0:16:26 0.0%
1 daemon 3744K 5752K 0.1% 0:00:00 0.0%
12 root 181M 135M 3.3% 0:01:11 0.0%
but since I run with most services disabled, it looked like the
resident memory size was a bit high, so I took a look at all the
processes in the db zone:
# prstat -s rss -z db
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
6755 mysql 69M 45M sleep 1 0 0:16:26 0.0% mysqld/12
459 root 10M 9008K sleep 59 0 0:00:21 0.0%
svc.configd/14
457 root 9308K 8172K sleep 29 0 0:00:10 0.0%
svc.startd/11
569 root 6648K 3280K sleep 59 0 0:00:37 0.0% nscd/26
671 root 3524K 1768K sleep 1 0 0:00:00 0.0% syslogd/11
713 root 4060K 1632K sleep 59 0 0:00:00 0.0% sshd/1
455 root 2432K 1484K sleep 1 0 0:00:02 0.0% init/1
676 root 2300K 1404K sleep 59 0 0:00:00 0.0% ttymon/1
668 root 2256K 1324K sleep 59 0 0:00:00 0.0% ttymon/1
654 root 2784K 1240K sleep 59 0 0:00:00 0.0% cron/1
561 daemon 3996K 1124K sleep 29 0 0:00:00 0.0% kcfd/2
663 root 1940K 1084K sleep 59 0 0:00:00 0.0% sac/1
6738 mysql 1312K 1000K sleep 1 0 0:00:00 0.0%
mysqld_safe/1
667 root 1252K 772K sleep 1 0 0:00:01 0.0% utmpd/1
443 root 0K 0K sleep 60 - 0:00:00 0.0% zsched/1
The RSS column for root sums up to 31168K - so where did "prstat -t"
get its 135M from?
cheers,
/Martin
