Netty4, Camel, Spring, standalone jar how to configure business transcation?

CommunityUser — Tue, 07 Nov 2017 09:55:45 GMT

Hi all,

I want to configure business transcation monitoring for a simple application. The code for it is there - repository.

It has 2 applications - Front and Back. Both applications uses Spring Boot, Netty and Apache Camel. Front application waitng for get request and passed it (using simple Camel route) to back application. Back application responses with hardcoded string.

While monitoring these applications using app dynamics agent, agent does not detect any business transactions.

How to configure agent to monitor whole transaction?

If you do not see a transaction flow in AppDynamics with only the out of the box configuration, it is because your transactions are not hitting any entry point instrumentation. In this case, that is because you are using the v4 netty http client and server, which are not covered by the out of the box instrumentation today.

If you add the following additional configuration to <agent-install-dir>/v4.x.y/conf/custom-activity-correlation.xml (within the <activities> element) you should see your transaction activity.

<producer>
<instrumentation>
<class-name>io.netty.handler.codec.http.HttpObjectEncoder</class-name>
<method-name>encodeHeaders</method-name>
<match-type>MATCHES_CLASS</match-type>
</instrumentation>
<identifiers>
<identifier name="HOST">
<data-gatherer-type>POSITION</data-gatherer-type>
<position>0</position>
<getter-chain>get(Host)</getter-chain>
<transformer-type>GETTER_METHODS</transformer-type>
</identifier>
</identifiers>
<correlation>
<payload-pointer>
<data-gatherer-type>POSITION</data-gatherer-type>
<position>0</position>
<getter-chain>this</getter-chain>
<transformer-type>GETTER_METHODS</transformer-type>
</payload-pointer>
<payload-operation>
<access-type>method</access-type>
<access-method>add</access-method>
<param-types>java.lang.String, java.lang.Object</param-types>
</payload-operation>

</correlation>
</producer>

<producer in-process="true" activity-type="NettyProcess">
<instrumentation>

</producer>

I have the same requirement. And I tried your method, it didnt work. It would be great help if you could help me auto discover Netty framework based proxy application.

Auto discovery for transactions originating in the netty 4 web server is a backlog item currently.

In the short term, you are best off working with support to identify a configuration that works for your environment.

Warm regards,
Peter

I need this instrumentation too.
