AAGM already ships a Prometheus and its Push-GatewayPushgateway. https://apiida.atlassian.net/wiki/spaces/AAGM/pages/7760183321/Installation#Install-using-Docker-Compose
Once set up successfully, everything should connect automatically and start collecting metrics from APIs registered in AAGM.
...
Using an external Prometheus
The url of Prometheus and the Prometheus Pushgateway must be stored in the configuration of AAGM under
...
General settings.
Prometheus must receive the
...
Pushgateway as target as in line 16 above.
Optionally, the database of AAGM can also be added. https://grafana.com/oss/prometheus/exporters/mysql-exporter/
View metrics directly in Prometheus
Here are a few examples of how to retrieve metrics directly in Prometheus.
Example: Nodes
...
cpuLoadPercentage{name="Docker GW 1"}
memoryLoadPercentage{hostPort="host.docker.internal:8444"}
cpuLoadPercentage
...
Example: APIs
...
allRequestsCount{name="APIIDA Metrics API"}
allRequestsCount{job="Docker GW 1 APIIDA Metrics API"}
allRequestsCount{nodeID="2"}
...
...
Jobs, Labels and Metric Names
https://prometheus.io/docs/concepts/data_model/#metric-names-and-labels https://prometheus.io/docs/concepts/jobs_instances/
All possible filters can also be viewed there here or directly on the PushGateway.

Jobs
The name of the job consists of the name of the gateway and the name of the API.
Labels
Enable the Prometheus dimensional data model to identify any combination of labels for the same metric name.
id
Id of the API or Node
name
Name of the API or Node
nodeId
Id of the node on which the API is running
type
Type of job, either “api” or “node”. Influences which metrics are available.
Metric Names
Specify the general characteristic of a system that is being measured
