Hi and thanks for trying out our APM solution! > [@fangfhm](#): > > 2019-01-21 09:50:22.910 [http-nio-9014-exec-6] INFO com.socialBureau.common.filter.UserInfoFilter -===========userValue===============\>null Looks like `com.socialBureau.common.filter.UserInfoFilter` is catching the NPE and prints an INFO message. Is that a ServletFilter? The Java agent reports errors for Transactions/Spans that end with an Exception. A ServletFilter is invoked within a FilterChain, which we instrument to capture transactions so if the Exception is caught without being rethrown within the chain, we don't have visibility to it. I hope this makes sense. Eyal. ---

hello,Thank you very much for your answer I don't quite follow you Can you give me a case ---

The Java agent is instrumenting methods in order to trace them. One of things we instrument in order to trace transactions is `javax.servlet.FilterChain#doFilter`. This method runs all registered servlet Filters as a chain, then runs the actual servlet (eg Spring's `FrameworkServlet` or `DispatherServlet`), which delegates execution to the relevant controller. If the controller is throwing an Exception and this Exception is caught quietly before the `FilterChain#doFilter` method execution finishes, we don't report this as error. The rationale is that only unhandled Exceptions are reported, but maybe we need to rethink this. What would you expect to get? All errors in controllers being reported? ---

Exceptions handled by try are not considered false? ![%E5%9B%BE%E7%89%87](https://us1.discourse-cdn.com/elastic/original/3X/e/e/ee63861736260be7a9e3c376eb7000bae80dd133.png) ---

We can't see handled Exceptions. For something like that, we may decide to add instrumentation to APIs such as the `R.error` from the above. However, you don't need to wait for something like that, you can [capture such errors programatically using our public API](https://www.elastic.co/guide/en/apm/agent/java/master/public-api.html#api-span-capture-exception) 🙂 . I hope this helps. Eyal. ---

I want to get all the error information. Is it ok ---
