OneAgent docker requirements

Hi,

I use Dynatrace Saas to monitor a Web Application deployed on Docker Swarm.

Docker Swarm cluster is composed of several hosts, with different containers each. OneAgent are installed on those hosts.

Could you give requirements per container (and not per host) needed for the OneAgent ? We know that it will use on each container some extra memory and CPU or disk space per container.

Best regards

Memory overhead is described in the help and is typically around 100MB per deep monitored process regardless of the containerization:

Disk space is described in the installation host:

CPU overhead depends on the configuration of Dynatrace, number of request attributes, purepath limit/etc. Typically this is almost unmeasurable (1-2% overhead).
