Recently i have observed that in APM transactions chart it is not showing me any break down that where time has mostly spent. ![image (1)](https://us1.discourse-cdn.com/elastic/original/3X/6/0/60852f4f52b1fcdfd45683bf277d290667f5dfa7.png) I was expecting the format in this way, but not sure why the break down chart is missing. ![Screenshot from 2023-03-06 11-05-50](https://us1.discourse-cdn.com/elastic/original/3X/8/a/8aff4b629c52dfc8df0fe5dd0c06a6853ed00c92.jpeg) ---

Hi ! Does your Java application relies on one of the [supported technologies](https://www.elastic.co/guide/en/apm/agent/java/current/supported-technologies-details.html) within this transaction ? For example, are you calling a database through JDBC API ? If the APIs you are using are listed ad supported, then you need to check the agent logs, in order to capture them properly you need to use [this procedure](https://www.elastic.co/guide/en/apm/agent/java/current/trouble-shooting.html#trouble-shooting-logging-procedure) with `log_level=debug`. If the APIs/libraries that you use are not supported, then you can still capture some information using the strategies described [here](https://www.elastic.co/guide/en/apm/agent/java/current/java-method-monitoring.html). ---

Issue is fixed, the problem is with CPU load. Once i have upgraded the hardware where APM is running, breakdown chart is showing. ---

Hi ! Thanks for keeping us posted here. From what I understand here, it means that you have enabled the [circuit breaker](https://www.elastic.co/guide/en/apm/agent/java/current/config-circuit-breaker.html) so any high cpu usage on your environment will make the agent self-disable and thus drop some tracing data. Is that correct ? ---

I haven't enabled circuit breaker. I have seen my resource is constantly 99%. Number of nodes when java agent is running is very high like 100. I though of increasing CPU capacity. It worked. ---
