# Description
|
|
|
|
This sample provides an environment to display and capture metrics from the test-network in real time. It consists of a docker-compose file that starts a prometheus and grafana server setup configured to collect and display metrics for the test network.
|
|
|
|
# Requirements
|
|
|
|
This sample is meant to be used on **linux** in order to fully benefit from its capabilities. However, it can be used and adapted on other systems with some additional work and tweaks.
|
|
|
|
You will need to have installed **docker-compose with version 1.29 or above**.
|
|
|
|
# How to use
|
|
|
|
1. Bring up the test-network
|
|
2. Bring up the Prometheus/Grafana network --> **docker-compose up -d**
|
|
3. Log in: type “< address >:3000” on your web browser -> username=“admin”, password=“admin”
|
|
4. Browse dashboard and analyze results
|
|
Extras: add new queries, modify dashboard & add relevant changes to main repo --> extract json and it to "grafana/dashboards/hlf-performances.json"
|
|
|
|
# Docker Compose
|
|
|
|
Brings up
|
|
- a prometheus sever (port 9090) --> pulls metrics from peers, orderer, system(node exporter) and containers(cadvisor)
|
|
- grafana sever (port 3000) --> collects and display data from prometheus
|
|
- node exporter (port 9100) --> exposes systems metrics
|
|
- cadvisor (port 8080) --> exposes docker conteners metrics
|
|
|
|
# Prometheus "confgaration file"
|
|
|
|
**Prometheus.yml**
|
|
|
|
Fabric metrics targets:
|
|
- peer0.org1.example.com:9444
|
|
- peer0.org2.example.com:9445
|
|
- orderer.example.com:9443
|
|
|
|
System and docker metrics targets:
|
|
- cadvisor:8080
|
|
- node-exporter:9100
|
|
|
|
Check the state of the connections with targets on http://localhost:9090/targets.
