[zones-discuss] monitor number of lwp in zone
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 NAMEPRIVILEGE VALUEFLAG ACTION RECIPIENT zone.max-lwps privileged120 - 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 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 ___ zones-discuss mailing list zones-discuss@opensolaris.org
