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

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
