= IG-MON-4: Infrastructure Device Performance Test = This page captures status for the test case IG-MON-4, which verifies that the rack head node performs well enough to run all the services it needs to run while !OpenFlow and non-OpenFlow experiments are running. For overall status see the [wiki:GENIRacksHome/InstageniRacks/AcceptanceTestStatus InstaGENI Acceptance Test Status] page. ''Last update: 2013/01/29'' = Test Status = This section captures the status for each step in the acceptance test plan. ||'''Step'''||'''State'''|| ''' Ticket ''' || '''Notes''' || || Step 1 || || || || || Step 2 || || || || || Step 3 || || || || [[BR]] || '''State Legend''' || '''Description''' || || [[Color(green,Pass)]] || Test completed and met all criteria || || [[Color(#98FB98,Pass: most criteria)]] || Test completed and met most criteria.

The rack used is the GPO rack and the following experiments are set up before head node device performance is reviewed: - IG-MON-4-exp1: IG GPO non-!OpenFlow experiment with 10 VM nodes, all nodes exchanging traffic. - IG-MON-4-exp2: IG GPO non-!OpenFlow experiment with 1 VM and one dedicated raw-pc, both exchanging traffic. - IG-MON-4-exp3: IG GPO !OpenFlow experiment with 2 nodes in rack exchanging traffic with 2 site GPO !OpenFlow campus resources. - IG-MON-4-exp4: IG GPO !OpenFlow experiment with 2 nodes exchanging traffic with 2 remote IG Utah !OpenFlow nodes. The setup of the experiments above is not captured in this test case, but the RSpec are available [insert_link_here]. Also traffic levels and types will be captured when this test is run. In addition to the 4 experiment listed above the following experiments were running on the GPO IG rack: [Insert_capture for https://boss.instageni.gpolab.bbn.com/showexp_list.php3] While the 4 experiments involving !OpenFlow and compute slivers are running, execute the steps below. == 1. View !OpenFlow control monitoring at GMOC and verify that no monitoring data is missing == == 2. View VLAN 1750 data plane monitoring == Verify the VLAN 1750 data plane monitoring which pings the rack's interface on VLAN 1750, and verify that packets are not being dropped == 3. Verify CPU idle percentage on the server host and the FOAM VM are both nonzero == = Additional Scenarios = This section captures some scenarios that are not in the original test plan, but have been captured as a data point for performance. == Mix of non-OF experiments == The first head node monitoring scenario was captured while the rack had 27 nodes allocated: [[Image(IG-MON-4-w27nodese.jpg)]] Head node the system was mostly idle: {{{ [lnevers@boss ~]$ top last pid: 6455; load averages: 0.05, 0.11, 0.13 up 48+22:16:24 15:19:20 140 processes: 1 running, 138 sleeping, 1 zombie CPU: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Mem: 384M Active, 1241M Inact, 187M Wired, 25M Cache, 93M Buf, 162M Free Swap: 2047M Total, 2420K Used, 2045M Free [lnevers@boss ~]$ ps -eao pcpu,pid,user,args | sort -r -k1 %CPU PID USER COMMAND 0.0 95092 elabman /usr/X11R6/bin/bash --noediting -i 0.0 95089 elabman /usr/X11R6/bin/bash --noediting -i 0.0 95086 elabman /usr/X11R6/bin/bash --noediting -i 0.0 95084 elabman /usr/X11R6/bin/bash --noediting -i 0.0 95083 elabman /usr/X11R6/bin/bash --noediting -i 0.0 95045 elabman dbus-launch --autolaunch=05f048b1db6b246dc4dcc41b00014cac --binary-syntax --close-stderr 0.0 95028 elabman emacs 0.0 94997 elabman bash -login 0.0 91498 elabman bash -login 0.0 90045 elabman bash -login 0.0 84248 elabman ssh pc1 0.0 83886 elabman bash -login 0.0 68989 elabman mysql geni-cm 0.0 55878 elabman emacs 0.0 49903 root tcppd (perl5.12.4) 0.0 39666 elabman mysql tbdb 0.0 38352 elabman mysql tbdb 0.0 33963 elabman /usr/X11R6/bin/bash --noediting -i 0.0 33959 elabman /usr/X11R6/bin/bash --noediting -i 0.0 33956 elabman /usr/X11R6/bin/bash --noediting -i 0.0 33954 elabman /usr/X11R6/bin/bash --noediting -i 0.0 33953 elabman /usr/X11R6/bin/bash --noediting -i 0.0 25286 elabman emacs -nw GeniCM.pm.in 0.0 16663 elabman bash -login 0.0 7518 lnevers sort -r -k1 0.0 7517 lnevers ps -eao pcpu,pid,user,args 0.0 6453 lnevers bash 0.0 6448 lnevers -tcsh (tcsh) 0.0 1709 root /usr/libexec/getty std.115200 console [lnevers@boss ~]$ uptime 3:27PM up 48 days, 22:25, 6 users, load averages: 0.17, 0.18, 0.15 [lnevers@boss ~]$ iostat tty da4 da1 da2 cpu tin tout KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us ni sy in id 0 3 26.01 0 0.01 20.72 0 0.00 7.91 1 0.01 1 0 1 0 98 }}} Similar results on the OPS node: {{{ last pid: 22804; load averages: 0.10, 0.06, 0.01 up 48+22:20:45 15:23:31 107 processes: 1 running, 106 sleeping CPU: 0.8% user, 0.0% nice, 0.4% system, 0.0% interrupt, 98.8% idle Mem: 166M Active, 871M Inact, 147M Wired, 8460K Cache, 95M Buf, 808M Free Swap: 2047M Total, 852K Used, 2046M Free [lnevers@ops ~]$ ps -eao pcpu,pid,user,args | sort -r -k1 %CPU PID USER COMMAND 0.0 98491 elabman bash -login 0.0 23097 lnevers sort -r -k1 0.0 23096 lnevers ps -eao pcpu,pid,user,args 0.0 23059 lnevers bash 0.0 23054 lnevers -tcsh (tcsh) 0.0 779 root /usr/libexec/getty std.115200 console 0.0 597 mysql /usr/local/libexec/mysqld --basedir=/usr/local --datadir=/var/db/mysql --user=mysql --pid-file=/var/db/ 0.0 530 root /bin/sh /usr/local/bin/mysqld_safe --pid-file=/var/db/mysql/mysqld.pid --user=mysql --log-long-format - [lnevers@ops ~]$ uptime 3:29PM up 48 days, 22:27, 2 users, load averages: 0.28, 0.13, 0.04 [lnevers@ops ~]$ iostat tty da3 da0 da4 cpu tin tout KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us ni sy in id 0 1 20.32 0 0.00 11.07 0 0.01 11.09 0 0.00 0 0 0 0 100 }}} On the FOAM node: {{{ lnevers@foam:~$ top top - 16:04:39 up 47 days, 4:08, 2 users, load average: 0.00, 0.01, 0.05 Tasks: 67 total, 1 running, 64 sleeping, 0 stopped, 2 zombie Cpu(s): 0.3%us, 0.0%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 756268k total, 587192k used, 169076k free, 147864k buffers Swap: 794620k total, 4444k used, 790176k free, 317560k cached lnevers@foam:~$ ps -eao pcpu,pid,user,args | sort -r -k1 %CPU PID USER COMMAND 0.6 12890 lnevers bash 0.1 12758 lnevers -bash 0.0 9 root [khelper] 0.0 8 root [cpuset] 0.0 8674 root /sbin/getty -L hvc0 9600 linux 0.0 8544 root /usr/sbin/sshd -D 0.0 7 root [watchdog/0] 0.0 6 root [migration/0] 0.0 6866 www-data /usr/bin/python /opt/foam/sbin/foam.fcgi 0.0 6858 www-data nginx: worker process 0.0 6857 www-data nginx: worker process 0.0 6856 www-data nginx: worker process 0.0 6855 www-data nginx: worker process 0.0 6854 root nginx: master process /usr/sbin/nginx 0.0 642 root /sbin/getty -8 38400 tty1 0.0 610 daemon atd 0.0 609 root cron 0.0 606 root /sbin/getty -8 38400 tty6 0.0 602 root /sbin/getty -8 38400 tty3 0.0 600 root /sbin/getty -8 38400 tty2 lnevers@foam:~$ uptime 16:06:12 up 47 days, 4:10, 2 users, load average: 0.04, 0.03, 0.05 lnevers@foam:~$ iostat Linux 3.2.0-34-generic (foam) 01/29/2013 _x86_64_ (1 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 0.60 0.00 0.33 0.00 0.00 99.06 Device: tps kB_read/s kB_wrtn/s kB_read kB_wrtn xvda 1.71 0.09 13.25 370717 54001250 dm-0 2.39 0.09 13.25 366389 53996104 dm-1 0.00 0.00 0.00 2324 5104 }}}
