Memory Analysis.

A Dynatrace ActiveGate acts as a secure proxy between Dynatrace OneAgents and Dynatrace Clusters or between Dynatrace OneAgents and other ActiveGates—those closer to the Dynatrace Cluster

Types of ActiveGates—Environment ActiveGates or Cluster ActiveGates

OneAgent is responsible for collecting all monitoring data within your monitored environment. A single OneAgent per host is required to collect all relevant monitoring data—even if your hosts are deployed within Docker containers, microservices architectures, or cloud-based infrastructure

If I enable memory dump analysis on multiple ActiveGates, which ActiveGate will perform the memory dump?

ActiveGates have a priority assigned automatically. If there is more than one ActiveGate with the same priority, an endpoint will be selected randomly.

What happens if a file transfer to an ActiveGate fails?

OneAgent attempts to send the dump list to all available endpoints until it finds one that works. This process is retried until it's successful or until the dumps are deleted by aging tasks (for example, if there are too many or if they are too old).

What happens if ActiveGate runs out of space for memory dumps?

ActiveGate will first delete outdated dumps. If there are no outdated dumps, ActiveGate will delete the oldest dumps first.

Difference between Elapsed Time, Self Time, Duration :-

Elapsed time shows the time the instrumented point in code started execution (calculated from the beginning of the purepath, so first entry will have zero time)

Self-time shows the duration of the code itself (the instrumented row), excluding subcalls

Duration shows the duration of the code itself including subcalls.

Synthetic Monitoring :-  you can troubleshoot with accuracy using detailed object-level, page, connection and host data across multiple browsers. It provides detailed diagnostics including DNS, connect time, SSL, first byte and content download times and errors, for every object on every page, and stored for postmortem and routine review.

Types of synthetic monitors: single-URL browser monitors, browser clickpaths, and HTTP monitors.
