add jmeter arg -f

[mohamed-atef2022]

this is th code i use
in which line i should edit
if [ -n "${enable_report}" ]; then
# report_command_line="--reportatendofloadtests --reportoutputfolder /report/report-${jmx}-$(date +"%F_%H%M%S")"
report_command_line="--reportatendofloadtests --reportoutputfolder /report/report-${jmx}-{{workflow.creationTimestamp}}"
fi

The error message wants to tell you, that the sample log file already exists and is not empty.

To fix this, discard the file (save it somewhere?) before starting the test run.

Maybe workflow.creationTimestamp is constant relative to all your test runs?

PS. Why do you use so much "echo 'some shell code'" that seems quite unreadable to me. And instead of disabling a shell-check rule, try to fix the code.

[linvaux]

@mohamed-atef2022 Why you show some shell code? you could add jmeter arg -f to delete logfile before rerun test, such as

jmeter -n -t script.jmx -l result.jtl -e -o ./report -f

[mohamed-atef2022]

i tried to solve it by fixing the echo commands
the report generated but i get this issue which prevent the report from copying in th path

overwrite it

@linvaux while i am using -f in jmeter command i think it doeesnt affect on the report creation or overwrite it

-f while delete the old logfile and try to generate new report, see

jmeter/src/core/src/main/java/org/apache/jmeter/JMeter.java

Line 994 in 3e9af5d

if (deleteResultFile) {

[mohamed-atef2022]

i tried to add the flag itself
jmeter ${param_user} ${param_properties} ${report_command_line} --logfile report-${jmx}-$(date +"%F_%H%M%S").jtl --nongui --forceDeleteResultFile --testfile ${jmx} -Dserver.rmi.ssl.disable=true --remoteexit --remotestart ${slave_list} >> jmeter-master.out 2>> jmeter-master.err
i tried also to delete it explicity from the container
but i get also this

It looks like your report directory is not empty when jemter generating report, could you check the report dir is empty?
by the way could you use markdown to replay when you show your code?

[mohamed-atef2022]

i jus checked it
th report directory has a data called report-template it is copied from /opt/jmeter/bin/report-template
i think it is a files that copied to be filled in by the load test result
but what i am confusing about why the flag of -f doesnt work
to overwrite the data

[linvaux]

@mohamed-atef2022 emm，you want to use jmeter cluster to run test and generate report?
