**Kibana version** : 7.4.0 **Elasticsearch version** : 7.4.0 **APM Server version** : 7.4.0 **APM Agent language and version** : APM Agent 1.7.0 **Browser version** : Chrome 78.0.3904 **Original install method (e.g. download page, yum, deb, from source, etc.) and version**: ELK Stack URL Download: [docker.elastic.co/elasticsearch](http://docker.elastic.co/elasticsearch) , Kibana and Beats APM Agent URL Download: [https://repo1.maven.org/maven2/co/elastic/apm/elastic-apm-agent/1.7.0/elastic-apm-agent-1.7.0.jar](https://repo1.maven.org/maven2/co/elastic/apm/elastic-apm-agent/1.7.0/elastic-apm-agent-1.7.0.jar) **Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**: I installed and let the ELK Stack configuration default. After that, i installed APM Agent Java in Tomcat Server and edited the setenv.sh: > export CATALINA\_OPTS="-Xms512M -Xmx3072M" > export CATALINA\_OPTS="$CATALINA\_OPTS -javaagent:/opt/tomcat/elastic-apm-agent-1.7.0.jar" > export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.service\_name=tomcat-appx" > export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.application\_packages=appx" > export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.server\_urls=[http://192.168.0.44:8200](http://192.168.0.44:8200)" I followed the wizard to enable APM Server and add service "tomcat-appx". Some transactions was classified like "GET Unknown route". ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/0/90d1e637e7e74cb54e13cf1a91f950bb8b6c37ea.png) How can i solved this? ---

Hi @dancristian, By default, transactions are named with the Servlet name that handled the request. Thus, if request does not reach a servlet, you get those `unknown route` transactions. There are two possible cases: - your requests reach a servlet but Elastic agent is not properly able to detect those - your requests do not reach a servlet: handled by filter, static resources, ... Regarding detection of Servlets, agent has a 'pre-filter' heuristic to only consider classes which name ends with 'Servlet'. This heuristic can be disabled by setting the internal configuration `enable_type_matching_name_pre_filtering=false`. Please note that this has an impact on all plugins, thus a small extra overhead during application startup time is expected. In the second case, it is possible to change the default transaction naming to use URL path instead. [use\_path\_as\_transaction\_name](https://www.elastic.co/guide/en/apm/agent/java/current/config-http.html#config-use-path-as-transaction-name). The major implication is that it may create lots of duplicate transactions if they have similar paths like `/usr/{id}` where `{id}` is the user ID, you can get as many transactions as there are users. Thus, if required, you can mitigate this by using [url\_groups](https://www.elastic.co/guide/en/apm/agent/java/current/config-http.html#config-url-groups), which will allow to use wildcards in transaction URLs. Another option is to set transaction names using our API: - use [ElasticApm.currentTransaction()](https://www.elastic.co/guide/en/apm/agent/java/current/public-api.html#api-current-transaction) to get current transaction - use [Transaction#setName(String name)](https://www.elastic.co/guide/en/apm/agent/java/current/public-api.html#api-set-name) to set transaction name Also, could you provide us some details about the application ? For example do you have a list of all servlets that should be instrumented ? ---
