• Configure Prometheus for collecting metrics from mini-node-exporter
• Configure Prometheus as a Grafana datasource
• Create a Grafana dashboard for showing the metrics provided by mini-node-exporter, in any forms

Orcherating the monitroing stack and mini-node-exporter application by kubernetes

Build a web app that listens on 0.0.0.0:23333, and expose the following endpoints:

• /info/hostname show the hostname with plain text
• /info/uptime show the uptime of the system in seconds with plain text
• /info/load show the load average in 1m, 5m and 15m with JSON, example {"1m": 0.57, "5m":0.80, "15m":0.77}
• /metrics expose metrics that could be scraped by prometheus

Required metrics that should be exposed in /metrics:

• node_load: load average, with a label for three duration
• node_uptime: uptime of the system in seconds

# TYPE node_load gauge
node_load{duration="1m"} 0.57
node_load{duration="5m"} 0.80
node_load{duration="15m"} 0.77
# TYPE node_uptime gauge
node_uptime 9246.58

• Build a docker image for the application
• Publish it on DockerHub
