I'm working on Logstash setup in a legacy system with no owners in the organisation. Using `ps`, i found the process executing the logstash service: ```auto /usr/bin/java -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -Djava.awt.headless=true -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -Djava.io.tmpdir=/var/lib/logstash -Xmx1g -Xss2048k -Djffi.boot.library.path=/opt/logstash/vendor/jruby/lib/jni -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -Djava.awt.headless=true -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -Djava.io.tmpdir=/var/lib/logstash -XX:HeapDumpPath=/opt/logstash/heapdump.hprof -Xbootclasspath/a:/opt/logstash/vendor/jruby/lib/jruby.jar -classpath : -Djruby.home=/opt/logstash/vendor/jruby -Djruby.lib=/opt/logstash/vendor/jruby/lib -Djruby.script=jruby -Djruby.shell=/bin/sh org.jruby.Main --1.9 /opt/logstash/lib/bootstrap/environment.rb logstash/runner.rb agent -f /etc/logstash/conf.d -l /var/log/logstash/logstash.log ``` I know the config file being used in the logstash service -\> `/etc/logstash/conf.d/ls.conf`. But I want to modify the service to use forked pipelines. But what I assume is the home dir ... `/opt/logstash` doesn't contain any `logstash.yml` or `pipelines.yml`. How do I restart the service to use the `pipelines.yml` I've written? ---

An update: `/opt/logstash/bin/logstash --version` says v2.2.4 ---

It is not possible, version `2.2.4` has no support to multiple pipelines (which is configured through `pipelines.yml`). The multiple pipelines was introduced only in version `6.0`. The only way to use multiple pipelines is to upgrade to a newer version, which you should do as soon as possible as `2.2.X` reached EOL in 2017. ---

Thanks for responding. I'm afraid of all the breaking changes from upgrading to +5 versions. ---

Also, how to find the .sincedb for 2.2.4? How to plan for the upgrade? I'm reading a ../.\*txt input using filebeat + logstash. ---

> [@GitSpree23](#): > > I'm afraid of all the breaking changes Working with the Elastic stack and being afraid of breaking changes is not a good match 😆 Elastic have no fear of introducing breaking changes when they think it provides enough benefit. That said, I realize you have been given a task to complete. What are you trying to do with multiple pipelines? The distributor and collector patterns can be implemented in a single pipeline using if-else blocks in the filter and/or output sections. A forked-path pattern can be implemented using a clone filter plus an if-else based on the type added by the clone filter. The output-isolator pattern cannot be implemented in old versions. ---

I'm working with a single input source (file path =\> "/abc/.\*txt") but want to use two different filter plugins for 2 different outputs - in the future I'm gonna downgrade the RabbitMQ output & persist the Kafka output. So I want to implement a forked path. I should upgrade the system since we're doing an architecture overhaul of the downstream application anyway. Just that I don't know what to tick off before upgrading. I think I should read the sincedb and provide the path in the new installation, but I can't find a '_sincedb_' anywhere in the system! ---

Update: Filebeat is actually reading the input & using 0.0.0.0:5044 as Logstash output. And it's v7.8. If I stop the Logstash service, will I lose events from Filebeat. Or will the last read checkpoint be persisted and read by the new Logstash? ---
