Jmeter JTL ans statiscts file parsing with Logstash and elasticsearch, you can find image on Docker Hub, statistics.json file is generated with jmeter html report.
- Where to get help:
- Parse Standard JTL (CSV Format).
- Possibility to filter requests based on regex filter (include and exclude filter) .
- Flag samplers generated by TransactionController based on regex (by default '.+').
- For TransactionController, calculate number of failing sampler and total.
- Add relative time to compare different Executions, variable TESTSTART.MS should be logged with property sample_variables
- Add Project name, test name, environment and executionId to organize results and compare different execution.
- Split Label name to have multi tags by request (by default split by '/').
- Flag subresult, when there is a redirection 302,.. Subrequest has a have a suffix like "-xx" when xx is the order number
- Supporting ElasticSearch and can be adapted for other tools.
- can also index custom field logged in file with property : sample_variables

The jmeter-logstash
images come in many flavors, each designed for a specific use case.
The images version are based on component used to build image, default use elasticsearch output:
- Logstash Version: 7.17.9 -> default for 7.17.
- Create Optional docker network (Called jmeter). If not used remove "--net jmeter " from all following docker command and adapt Elasticsearch url.
docker network create jmeter
- Start elastic search container , Or use any Elasticsearch instance you have already installed.
docker run --name jmeter-elastic --net jmeter \
-p 9200:9200 -p 9300:9300 \
-e "ES_JAVA_OPTS=-Xms1024m -Xmx1024m" \
-e "xpack.security.enabled=false" \
-e "discovery.type=single-node" \
docker.elastic.co/elasticsearch/elasticsearch:8.4.1
- Start Kibana and connect it to elastic search Using environnement variable ELASTICSEARCH_HOSTS.
docker run --name jmeter-kibana --net jmeter -p 5601:5601 -e "ELASTICSEARCH_HOSTS=http://jmeter-elastic:9200" docker.elastic.co/kibana/kibana:8.4.1
- In the project folder create a folder named 'input' or you can use any input folder in your machine.
- If you choose to use a different input folder, you should change "${PWD}/input" on the following command by your input folder.
#Run Image
docker run --rm -it --net jmeter -e "ELASTICSEARCH_HOSTS=http://jmeter-elastic:9200" -v ${PWD}/input:/input/ anasoid/jmeter-logstash

- To exit after all files parsed use (-e "FILE_EXIT_AFTER_READ=true") should be used with ( -e " FILE_READ_MODE=read") ..
- To not remove container logstash after execution not use --rm from arguments.
- Logstash keep information on position f last line parsed in a file sincedb, this file by default is on the path /usr/share/logstash/data/plugins/inputs/file, if you use the same container this file will be persisted even you restart logstash cotainer, and if you need to maintain this file even you remove container you can mount volume folder in the path (/usr/share/logstash/data/plugins/inputs/file)
- To have relative time for comparison test start time should be logged : in user.properties file (sample_variables=TESTSTART.MS,...) or add properties with file using -q argument or directly in command line with (-Jsample_variables=TESTSTART.MS,..) see Full list of command-line options
Run Logstash without remove container after stop.
docker run -it --net jmeter -e "ELASTICSEARCH_HOSTS=http://jmeter-elastic:9200" \
-v ${PWD}/input:/input/ \
anasoid/jmeter-logstash
Run Logstash and remove file after the end of reading.
docker run --rm -it --net jmeter -e "ELASTICSEARCH_HOSTS=http://jmeter-elastic:9200" \
-v ${PWD}/input:/input/ \
-e "FILE_READ_MODE=read" \
-e "FILE_COMPLETED_ACTION=delete" \
anasoid/jmeter-logstash
Run Logstash with external sincedb folder.
```shell
docker run --rm -it --net jmeter -e "ELASTICSEARCH_HOSTS=http://jmeter-elastic:9200" \
-v ${PWD}/input:/input/ \
-v ${PWD}/.sincedb:/usr/share/logstash/data/plugins/inputs/file \

- Logstash instance can't parse CSV file with different header Format, as first header will be used for all file, if you have files with different format you should use each time a new instance or restart the instance.
- Change sincedb file can't done on logstash with Elasticsearch without building image.
- Label with suffix '-{number}' will be considered as subresult, so don't prefix label with '-{number}' or disable subresult flag with PARSE_WITH_FLAG_SUBRESULT.
