Prometheus Exporter Output Plugin

Description

Prometheus is an open source system for monitoring and alerting based on the collection (pull-based) of metrics in a Time Series Data Base (TSDB).

The plugin developed is an standard prometheus exporter which is exposed as a web service (with endpoint /metrics) to be reached by the prometheus system to pull the alumet's metrics.

Configuration

The plugin can be configured via the alumet's config.toml file with the following options:

[plugins.prometheus-exporter]
host = "0.0.0.0"
prefix = ""
suffix = "_alumet"
port = 9091
append_unit_to_metric_name = true
use_unit_display_name = true
add_attributes_to_labels = true

Examples

The plugin has been tested on both, local environment and a K8s.

Simple local example

The plugin can be tested in a local environment with the Alumet's default configuration for it and results in the ability of downloading the metrics from http://localhost:9091/metrics.

Note that the list of metrics available will vary based on the input plugins used.

For the K8s demo, Alumet was installed with the it's default configuration in the host of a NUC where there was a single-node k3s cluster. After installing the default kube-prometheus-stack, the following manifest was deployed to scrape the exporter:

apiVersion: monitoring.coreos.com/v1alpha1
kind: ScrapeConfig
metadata:
  name: alumet-host-scrape
  labels:
    release: promstack
spec:
  staticConfigs:
    - labels:
        job: alumet-host
      targets:
        - my_host_ip:9091

For the demo, the "stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M" command was used to ensure that data was pulled correctly. This resulted in Grafana and Prometheus to correctly capture the behavior of the system as shown in the figure below.
