Dear List,
with the solaris resource control feature you are able to set the max
number of LWP for a zone
e.g
bash-3.00# prctl -n zone.max-lwps -i zone v0136
zone: 20: v0136
NAME PRIVILEGE VALUE FLAG ACTION
RECIPIENT
zone.max-lwps
privileged 120 - deny
-
system 2.15G max
deny -
with the rctladm you're able to generate warning if the limit was reached:
Apr 26 16:34:52 g0057 genunix: privileged rctl zone.max-lwps (value 120)
exceeded by process 15930 in zone v0136.
is there a "simple" way to get the actual value of the zone(s)?
actual known ways:
prstat:
/usr/bin/prstat -LZ
with sed,grep and awk possible:
/usr/bin/prstat -LZ -n 1,10 1 1 | sed '1,3d' | grep -v Total
0 216 111M 139M 6.8% 0:09:05 0.1% global
20 100 40M 23M 1.1% 0:00:32 0.0% v0136
Potential improvements on that are:
$ ps -Leo zone | sort | uniq -c | sort -n
1 ZONE
110 z1
319 global
$ ps -Lz z1 -o pid= | wc -l
109
The reason that these are improvements are:
- We don't force ps to do any name lookups. If name lookups are broken for some
reason (e.g. ldap server failure), you want to minimize the amount of monitoring
that breaks.
- No use of imprecise grep patterns that could match process names or substrings
of other zones.
- If you have a lot of zones, prstat may not list the least active ones.
kstat:
kstat -p unix:0:lwp_cache:buf_inuse
unix:0:lwp_cache:buf_inuse 319
but I get only the sum of all lwp on the system, not for a special zone
ps:
ps -efZ -o zone,zoneid,lwp,args | grep global | wc -l
219
ps -efZ -o zone,zoneid,lwp,args | grep v0136 | wc -l
105
on Solaris 11 it is possible to get these values by zonestat
e.g.
$ zonestat -p -P zones -r processes,lwps 1 1
interval:processes:system-limit:global:66:0.22%:-:-
interval:processes:system-limit:v0134:30:0.10%:-:-
interval:lwps:system-limit:global:670:0.00%:-:-
interval:lwps:system-limit:v0134:112:0.00%:-:-
but for solaris 10?
any hints are very welcome
regards
Christian
