In terms of what could be improved, Elastic APM's visualization is not that great compared to other tools. It's number of metrics is very low. Their JVM metrics are much less while running on CPU memory and on top of that you get a thread usage. They're not giving much on application performance metrics. In that respect, they have to improve a little bit. If you compare that with other tools, such as New Relic, which is also not giving many insights, it would be good to get internal calls or to see backend calls. We are not getting this kind of metric. On the other hand, if you go to the trace view, it gives you a good backend calls view. That backend call view is also capturing everything, and we need some kind of control over it, which it does not have. For example, if I don't want some of the sequence selected, there should be controls for that. Moreover you need to do all these things manually. Nowadays, just imagine any product opted to do conservation manually, that would be really disastrous. We don't want to do that manually. For now this needs to be either by API or some kind of automated procedure. If you want to install the APM Agent, because it is manual we would need to tune it so that the APIs are available for the APM site. That's one drawback. Additionally, the synthetic monitoring and real user monitoring services are not available here. Whereas in New Relic the user does get such services. The third drawback I see is the control site. For now, only one role is defined for this APM. So if I want to restrict the user domain, for example, if in your organization you have two or three domains, domain A, domain B, domain C, but you want to give access to the specific domain or a specific application, I am not sure how to do that here. Both the synthetic and process monitoring should be improved. For the JVM, Java Process Monitoring, and any process monitoring, they have to have more metrics and a breakdown of the TCP/IP, and the tools are giving me - they don't provide many metrics in size. You get everything, but you fail to visualize it. The New Relic only focuses on transactions, and Elastic APM also focuses on similar stuff, but I am still looking for other options like thread usage, backend calls, front end calls, or how many front end and backend calls. This kind of metric is definitely required. We don't have much control. For example, some backend calls trigger thousands of prepared statements, update statements, or select statements, and we don't have any control. If I only want select statement, not update statements, this kind of control should be there and properly supplied. The property file is very big and it is still manual, so if you want control agent properties you need UI control or API control. Nowadays, the world is looking for the API site so they'll be able to develop more smartly. They are looking for these kinds of options to enrich their dashboard creation and management.
