Hi there,  
there is a logstash filter plugin called elapsed.

> **[Elapsed filter plugin | Logstash Reference \[7.8\] | Elastic](https://www.elastic.co/guide/en/logstash/7.8/plugins-filters-elapsed.html)**

  
I put (also) this into a config:  
elapsed {  
unique\_id\_field =\> "reqid"  
start\_tag =\> "TranBegin"  
end\_tag =\> "TranEnd"  
new\_event\_on\_match =\> false  
}  
and made just for a test:
## bin/logstash -f /home/m0001637/test/logstash-7.8.1/config/logstash2.conf --config.test\_and\_exit

The result was:  
[2020-12-21T06:55:20,407][ERROR][logstash.plugins.registry] Tried to load a plugin's code, but failed. {:exception=\>#\<LoadError: no such file to load -- logstash/filters/elapsed\>, :path=\>"logstash/filters/elapsed", :type=\>"filter", :name=\>"elapsed"}  
[2020-12-21T06:55:20,415][FATAL][logstash.runner] The given configuration is invalid. Reason: Unable to configure plugins: (PluginLoadingError) **Couldn't find any filter plugin named 'elapsed'**. Are you sure this is correct? Trying to load the elapsed filter plugin resulted in this error: no such file to load -- logstash/filters/elapsed  
[2020-12-21T06:55:20,419][ERROR][org.logstash.Logstash] java.lang.IllegalStateException: Logstash stopped processing because of an error: (SystemExit) exit

Why so? Logst. could not find that filter, but such filter does exist if you see the documentation. I am running 7.8.1.

Any help is appraciated.  
Thanks.

Found the reason: it is not a deafult plugin.  
`bin/logstash-plugin install logstash-filter-elapsed`  
cheers
