Hi Team,
I have a simple lab application built on:
- Node.js application
- PostgreSQL backend
The PostgreSQL database is running as a Docker container service.
Environment details:
- Dynatrace OneAgent version: 1.337
- Full-stack monitoring enabled
- Container was restarted after OneAgent installation
- Using Dynatrace Gen3
Observation:
Dynatrace is able to monitor the container metrics successfully
CPU usage
Memory usage
Container metrics
When I manually stop the PostgreSQL container, I can see the CPU/Memory metrics dropping to zero
However:
Dynatrace is not generating any Problem or Alert when the container goes down
Nothing appears under Problems/Alerts
I also tried:
Process Availability policy
Matching process using:
Executable
Command line
$contains(postgres)
But still no alert is generated when the container stops.
My expectation:
I would like to generate an alert/problem whenever the PostgreSQL container service becomes unavailable/down.
Questions:
- Does Dynatrace Gen3 require additional configuration for container process availability alerts?
- Is Process Availability policy the correct approach for Docker containers?
- Should this be configured through:
Process monitoring rules
Kubernetes/container workload alerts
Custom metric events
Service availability monitoring
Is there any limitation with standalone Docker containers in Gen3?
Any guidance or best practice would be appreciated.
Thanks,
selvam
