Can investigate each issue from the point where it started, through root cause analysis,
and all the way to its ultimate resolution.
Dynatrace Managed first step
To obtain a Dynatrace Managed license
Dynatrace SaaS first step
Install ActiveGate
ActiveGate
Proxy between Dynatrace OneAgent and Dynatrace Server. ActiveGate is highly
recommended for both SaaS and Managed deployments.
OneAgent
-Collecting all monitoring data within your monitored environment.
-Injects all tags required for UX monitoring into the HTML of your application pages.
-Monitors: servers, applications, services, databases, processes, cloud instances,
hosts, network health, processes, and services.
ActiveGate use cases
-Access sealed networks
-Store memory dumps
-Control load distribution of AWS monitoring
-Collect external logs
-Monitor using an ActiveGate plugin
-Monitor virtualized infrastructure
-Execute local HTTP monitors
8443
-Must be open for HTTPS communication with a Managed node (Cluster/Environment
ActiveGate)
custom.properties file
To configure an ActiveGate setting (for example, proxy, port, or memory dumps) (and
then restart ActiveGate)
Check which Environment ActiveGate version you've installed
Nav menu > Deployment status > Dynatrace ActiveGates tab >
Check which Cluster ActiveGate version you've installed
Management Console > home page > Click a Cluster ActiveGate component
Main functions of ActiveGate
-Message routing
-Buffering and compression
, -Authentication
-Entry point for sealed networks

Data Center
(base level)
-A group of virtual machines running a cloud instance (OR a set of vCenter-based
virtual hosts) that transmit data to Dynatrace via a single security gateway
-Each virtual host must have Dynatrace OneAgent installed
-Needs a security gateway
Host
Physical or virtualized operating centers that provide memory and storage resources
(denoted with OS logo or generic logo)
Process
Visualizations of each node that corresponds to a process (not all displayed maybe)
Services
-Sets of code that accept requests and return results.
-Each node = different service.
Opaque Services
-Services detected on the calling side for which code-level visibility isn't available.
-Can determine how they're processed but can't monitor directly.
-Generic symbol.
Applications
No dependencies b/c of perspective of user
Application score
-Based on application Apdex ratings
-Average of application Apdex value and the percentage of user actions that are not
affected by problems.
Services score
The percentage of service calls that were successful and unaffected by problems
Infrastructure score
Percentage of host time during which no problems were encountered
Metadata
Key/value pairs that are inherent to any monitored entity (shown in the Properties
section of any entity)
Tag
-Labels or markers.
-Not information about an entity and don't belong to one specific entity
-Used to identify certain sets of entities.
Key Request Longevity
0-14 days (1-min)
14-28 days (5-min)
