Agentless monitoring Infra

[sbarraganp]

Hi, im new with Dynatrace and I want to know if I use agentless installation through the javascript code can Dynatrace detect the infrastructure of the server (hosted in heroku) or what are the limitations of this installation?

Hi Santiago,

Agentless monitoring will not be able to detect the infrastructure of the server. Agentless monitoring only injects into the web page where it gathers performance data from a browser perspective. In order to gather performance data about the infrastructure you will need to install OneAgent on the server.

Hello,

Agentless monitoring won't be able to detect infrastructure components. An agent is needed to detect and report on those. Agentless monitoring should mainly be reserved for situations where one is using AMP or doesn't have access to install the agent on their servers. An additional limitations of this installation is that you'll need to manually insert the RUM JavaScript tag into each application page, which is something that the OneAgent would handle for you. I'll link a document that can help explain some of the limitations and installation steps in more detail.

Hope this helps!

@Santiago B. Agentless monitoring is primarily only used to monitor hosts that cannot be monitored by the oneagent to gain application data. For example, if Easytravel ran on a very old platform, but you wanted to monitor it. You could go with the agentless option. You will gain information at the application level, but not host information like CPU, Memory Etc...
