How to run DTRACE tests on VM environment

Note : If you already created dilos_BASE BE according the instruction, and there is no any new tested stable version, just execute the following command:

beadm activate dilos_BASE

In other case if you have already the dilos_ISO_orig BE - make the command:

beadm activate dilos_ISO_orig

Then reboot and start the instruction from the section Step 6. Prepare VM for Tests Running:

reboot

If you have no one of these 2 BEs then start the instruction from the beginning.

Note : Create ztest user if you forgot to do it according the instruction:

sudo useradd -m -d /var/ztest -g staff -s /bin/bash ztest

sudo passwd ztest

echo "ztest ALL=(ALL:ALL) NOPASSWD: ALL" >> /etc/sudoers.d/ztest

Note : If you already did it on the previous step when preparing VM to run, then you can skip this step and go to the next one.

Note : You can run the test using a shell script. It can be created with any text editor or by executing the following command:

ztest@zone:~# cat > test-script.sh <<EOT

#!/bin/bash

ipa=\$(sudo ifconfig | grep -A 1 vmxnet3s0 | sed '1d; s/^[ \\t]*inet[ \\t]*//; s/[ \\t]*netmask.*\$//')

LOG="/var/tmp/dtrace-test.\$(date +%F-%T).txt"

uname -a > \${LOG}

echo "IP Address : \${ipa}" >> \${LOG}

START_TIME=\$(date +%s)

sudo /opt/SUNWdtrt/bin/dtest -d /var/tmp 2>&1 | /usr/bin/tee -a /var/tmp/a.tmp

END_TIME=\$(date +%s)

delta=\$((\$END_TIME - \$START_TIME))

sec=\$((\$delta % 60))

let "amin = \$delta / 60"

let "hour = \$amin / 60"

min=\$((\$amin % 60))

total=\$(grep 'total:' /var/tmp/a.tmp | sed 's/^[ \\t]*total:[ \\t]*//;s/[ \\t]*\$//')

passed=\$(grep 'passed:' /var/tmp/a.tmp | sed 's/^[ \\t]*passed:[ \\t]*//;s/[ \\t]*\$//')

result=\$(echo "scale=1; \${passed}*100.0/\${total}" | bc)

echo "Percent Passed: \${result}%" | /usr/bin/tee -a /var/tmp/a.tmp

printf "Running Time: %02d:%02d:%02d\n" \${hour} \${min} \${sec} | /usr/bin/tee -a /var/tmp/a.tmp

echo "" >> \${LOG}

sed -n '/== TEST RESULTS ==/,/Running Time:/p' /var/tmp/a.tmp >> \${LOG}

echo "" >> \${LOG}

echo "------------------------ FAILED -------------------------" >> \${LOG}

grep 'ERROR:' /var/tmp/a.tmp >> \${LOG}

echo "" >> \${LOG}

echo "---------------------------------------------------------" >> \${LOG}

cat /var/tmp/a.tmp >> \${LOG}

sudo rm -f /var/tmp/a.tmp

EOT

ztest@zone:~# sed -i '/./!d' test-script.sh &&chmod 777 test-script.sh

After running of this script you will find the log in the /var/tmp/dtrace-test.<ISO TIME>.txt file. It will contain information in the format that is used in Test Results.

If you use the SCREEN utility (how it was described earlier), your command will look like this:

ztest@zone:~# screen ./test-script.sh

Then you can disconnect in any time by pressing Ctrl-A d and connect back in the new SSH session by the command:

ztest@zone:~# screen -r

If you do NOT want to use the SCREEN utility, your command will be just:

ztest@zone:~# ./test-script.sh
