Hi Alan,
I'm afraid you missed the mailing list. :)
Finally I have managed to show the measurement in LAVA, though the unit is still missing:
https://validation.linaro.org/dashboard/streams/anonymous/botao-sun/bundles/...
https://validation.linaro.org/dashboard/attachment/791281/view
I tested the regular expression on a website and locally, it works well on both, for example:
1. Tested on a third-party website: https://pythex.org/?regex= ^%28%3FP%3Ctest_case_id%3Efio_\w%2B%29%3A\s%28%3FP%3Cresult%3E\w%2B%29\s%28%3FP%3Cmeasurement%3E[0-9.]%2B%29\s%28%3FP%3Cunits%3E\w%2B%29.*&test_string=fio_read%3A%20PASS%201105%20IOPS%0Afio_read%3A%20PASS%200%20NA%0Afio_read%3A%20FAIL%200%20NA%20-%20Command%20ran%20failed%20on%20%2Fdev%2Fsda&ignorecase=0&multiline=1&dotall=0&verbose=0
2. Tested locally:
#!/usr/bin/env python import re
test_string_pass = testcase_name + ": PASS" + " " + iops_result + " " + "IOPS" print test_string_pass test_string_pass_simple = testcase_name + ": PASS" + " 0" + " NA" print test_string_pass_simple test_string_fail = testcase_name + ": FAIL" + " 0" + " NA" + " - Command ran failed on /dev/sda" print test_string_fail
pattern = '^(?P<test_case_id>fio_\w+):\s(?P<result>\w+)\s(?P<measurement>[0-9.]+)\s(?P<units>\w+).*'
print re.findall(pattern, test_string_pass) print re.findall(pattern, test_string_pass_simple) print re.findall(pattern, test_string_fail)
The output is:
fio_read: PASS 1105 IOPS fio_read: PASS 0 NA fio_read: FAIL 0 NA - Command ran failed on /dev/sda [('fio_read', 'PASS', '1105', 'IOPS')] [('fio_read', 'PASS', '0', 'NA')] [('fio_read', 'FAIL', '0', 'NA')]
As you can see all four groups are captured there.
Any idea?
Thanks.

Hi Botao;
I've had the most luck using the lava test shell api "lava-test-case", have you tried it?
Senthil/LAVA team, do we have some examples of using parsers and measurements?

Hi,
I'm recently working on some test cases which involve the measurement, but have no idea how to handle it after several failures occurred. For example:
https://validation.linaro.org/scheduler/job/126298
<LAVA_SIGNAL_STARTRUN fio-ubuntu db652397-5831-4cc3-b2b3-1246879ac696> echo LAVA_ACK /root test_case_id:fio_device_existence result:PASS which fio The FIO binary location is: /usr/bin/fio test_case_id:fio_existence result:PASS sudo fio -filename=/dev/sda -rw=read -direct=1 -iodepth 1 -thread -ioengine=psync -bs=4k -numjobs=1 -runtime=10 -group_reporting -name=fio_read > fio_read.txt 2>&1 0 The IOPS number in fio_read test is: 1104 test_case_id:fio_read result:PASS measurement:1104 units:persecond <LAVA_SIGNAL_ENDRUN fio-ubuntu db652397-5831-4cc3-b2b3-1246879ac696> <LAVA_DISPATCHER>2014-05-13 12:30:39 PM WARNING: Invalid measurement <LAVA_DISPATCHER>2014-05-13 12:30:39 PM WARNING: Invalid measurement
The regular expression I'm using is:
"^test_case_id:(?P<test_case_id>fio_\w+)\sresult:(?P<result>(PASS|FAIL))\s*(measurement:)*(?P<measurement>\d*)\s*(units:)*(?P<units>\s*)\s*"
which if convert it to a solid one would be:
"^test_case_id:fio_\w+\sresult:(PASS|FAIL)\s*(measurement:)*\d*\s*(units:)*\s*\s*"
And it has been tested locally which can capture following 3 different results (sample):
test_case_id:fio_read result:PASS measurement:1105 units:persecond test_case_id:fio_read result:PASS test_case_id:fio_read result:FAIL - Command ran failed on /dev/sda
A local test script in Python is:
#!/usr/bin/env python import re
pattern_solid = "^test_case_id:fio_\w+\sresult:(PASS|FAIL)\s*(measurement:)*\d*\s*(units:)*\s*\s*" testcase_name = "fio_read" iops_result = "1105"
test_string_pass = "test_case_id:" + testcase_name + " result:PASS " + "measurement:" + iops_result + " units:persecond" test_string_pass_simple = "test_case_id:" + testcase_name + " result:PASS" test_string_fail = "test_case_id:" + testcase_name + " result:FAIL" + " - Command ran failed on /dev/sda"
print re.search(pattern_solid, test_string_pass) print re.search(pattern_solid, test_string_pass_simple) print re.search(pattern_solid, test_string_fail)
So would you provide an example about how to deal with the measurement in LAVA?
Thanks.
