# devopsgym / testgen__elastic__logstash-15000 - taskset: [devopsgym](https://harnessreport.com/tasks/devopsgym.md) - difficulty: hard - category: test-generation - language: - runnable from the site: no - agent timeout: 3000s ## Results by harness _none yet_ ## Instruction ``` The following text contains a user issue (in <issue/> brackets) posted at a repository. Further, you are provided with file contents of several files in the repository that contain relevant code (in <code> brackets). It may be necessary to use code from third party dependencies or files not contained in the attached documents however. Your task is to identify the issue and implement a test case that verifies a proposed solution to this issue. More details at the end of this text. <issue> **Logstash information**: Please include the following information: 1. Logstash version (e.g. `bin/logstash --version`) 8.6 3. Logstash installation source (e.g. built from source, with a package manager: DEB/RPM, expanded from tar or zip archive, docker) .tar.gz 4. How is Logstash being run (e.g. as a service/service manager: systemd, upstart, etc. Via command line, docker/kubernetes) CLI **Plugins installed**: (`bin/logstash-plugin list --verbose`) Nothing additional **JVM** (e.g. `java -version`): Bundled **OS version** (`uname -a` if on a Unix-like system): Macos **Description of the problem including expected versus actual behavior**: Expected behavior according to the [documentation](https://www.elastic.co/guide/en/logstash/current/dead-letter-queues.html#age-policy) is: > The age policy is verified and applied on event writes and during pipeline shutdown. but the Dead Letter Queue is not emptied on shutdown even though the documents retain age is exceeded. **Steps to reproduce**: logstash-sample.conf ``` input { file { path => "/tmp/dlq_test.log" } } output { elasticsearch { index => "dlq_test" cloud_id => "$ID" cloud_auth => "$AUTH" } } ``` logstash.yml ``` dead_letter_queue.enable: true dead_letter_queue.max_bytes: 5333mb dead_letter_queue.storage_policy: drop_older dead_letter_queue.retain.age: 1m ``` ES Index ``` PUT dlq_test { "mappings": { "properties": { "message": { "type": "boolean" } } } } ``` Start Logstash ``` bin/logstash -f ./config/logstash-sample.conf ``` Check DLQ is empty ``` cat data/dead_letter_queue/main/1.log 1% ``` Write into logfile, confirm document is in DLQ ``` echo "Hello world" >> /tmp/dlq_test.log cat data/dead_letter_queue/main/1.log 1c�������y�023-01-23T12:48:35.700302Ze�qjava.util.HashMap�dDATA�xorg.logstash.ConvertedMap�dhost�xorg.logstash.ConvertedMap�dname�torg.jruby.RubyStringxHOST���j@timestamp�vorg.logstash.Timestampx023-01-23T12:48:35.519808Z�clog�xorg.logstash.ConvertedMap�dfile�xorg.logstash.ConvertedMap�dpath�torg.jruby.RubyStringq/tmp/dlq_test.log�����eevent�xorg.logstash.ConvertedMap�horiginal�torg.jruby.RubyStringkHello world���h@versiona1gmessage�torg.jrubelasticsearchCould not index event to Elasticsearch. status: 400, action: ["index", {:_id=>nil, :_index=>"dlq_test", :routing=>nil}, {"host"=>{"name"=>"HOSTl"}, "@timestamp"=>2023-01-23T12:48:35.519808Z, "log"=>{"file"=>{"path"=>"/tmp/dlq_test.log"}}, "event"=>{"original"=>"Hello world"}, "@version"=>"1", "message"=>"Hello world"}], response: {"index"=>{"_index"=>"dlq_test", "_id"=>"CS6s3oUBXiJuXpohWyiN", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse field [message] of type [boolean] in document with id 'CS6s3oUBXiJuXpohWyiN'.
