If you don't need your OneAgent to run in the full-stack monitoring mode, you can also use one of the two lightweight modes that provide you with the subset of OneAgent metrics, focusing on your host infrastructure:

The table below shows an overview of available monitoring options for each of the monitoring modes.

For more information on Infrastructure Monitoring and Discovery modes for Application Security, see Application Security and monitoring modes

Discovery mode

OneAgent version 1.281+

OneAgent Discovery mode provides basic metrics enabling you to discover your hosts and processes and learn the potential to extend your monitoring.

We recommend that you deploy OneAgent in Full-Stack Monitoring mode to monitor your business-critical applications. Similarly, we recommend that you monitor critical infrastructure, like databases, queues, and messaging systems with Infrastructure Monitoring. OneAgent in Discovery mode can be deployed across the remainder of your infrastructure for full visibility thanks to its relatively low cost.

Discovery mode is available only if you're using the Dynatrace Platform Subscription model. License consumption is via the Foundation & Discovery capability. To learn more, see Host monitoring.

The following built-in metrics are available in Discovery mode:

CPU

Memory

Availability

Disk

Network

Enable Discovery mode

You enable Discovery mode at the host level, either during or after OneAgent installation.

Code-module injection

For Application Security to work in Discovery mode, code-module injection is required. Code-module injection is disabled by default.

After enabling Discovery mode, you can enable the code-module injection for a single host.

For details on how Application Security works in Discovery mode, see Application Security: Discovery mode.

Infrastructure Monitoring mode

While Full-Stack mode provides complete application performance monitoring, code-level visibility, deep process monitoring, and Infrastructure Monitoring (including PaaS platforms) for use cases where less visibility is required, OneAgent can be configured for Infrastructure Monitoring mode, which provides physical and virtual infrastructure-centric monitoring, along with log monitoring and AIOps.

Enable Infrastructure Monitoring mode

You enable Infrastructure Monitoring mode at the host level, either during or after OneAgent installation.

Process injection

Process injection provides you with additional data for Infrastructure Monitoring. Process injection is enabled by default.

Infrastructure Monitoring mode enables you to monitor any infrastructure component and backing service written in Java. You can monitor backing services supported by default (for example, Kafka or ActiveMQ), and you can also build your own custom JMX and PMI extensions for infrastructure components and use them in Infrastructure Monitoring mode.

Additionally, with process injection, Infrastructure Monitoring mode provides runtime metrics for:

Disable process auto-injection

We don't recommend disabling auto-injection, but if you're required to do so due to strict security requirements, you can choose among a variety options. Note that disabling auto-injection also prevents Dynatrace from discovering vulnerabilities in your environment, even if you have Application Security enabled. You can disable automatic injection at the host or environment level.

Disable auto-injection for a single host

Disable auto-injection for an environment

Filter hosts by injection status

When you disable auto-injection, you can find such hosts using the Auto-injection filter on the Deployment Status page or OneAgent on a host API.

Virtualization monitoring

Dynatrace supports virtualization monitoring. To monitor the virtual components in your environment, you need to complete an extra step beyond initial setup. For full details, see Set up virtualization monitoring.
