EOSMON - monitoring EOS,TELOS,BOS,MEETONE using Node Exporter, Prometheus and Grafana.

Both exporter and the template (Prometheus/Grafana) are public and they demonstrate a possibility to display basic metrics of EOS-like networks such as ( EOS, TELOS, BOS, MEETONE), thus the metrics exporter should be installed and launched for every single network. It’s also planned to expand the number of chain specific metrics, so that we can have a detailed and complete picture of each ecosystem. In this regard, public contribution is welcomed!

You can find an example grafana dashboard for this setup on https://grafana.com/grafana/dashboards/11070

Requirements:

1. Node exporter
2. Prometheus
3. Grafana
4. apt install jq

Start Node Exporter with collector.textfile.directory.

Create directory:

mkdir -p /var/lib/node_exporter/textfile_collector
  
chown node_exporter:node_exporter /var/lib/node_exporter/textfile_collector  

Change service file:

vim /etc/systemd/system/node_exporter.service  
[Unit]  
Description=Node Exporter  
Wants=network-online.target  
After=network-online.target  
  
[Service]  
User=node_exporter  
Group=node_exporter  
Type=simple  
ExecStart=/usr/local/bin/node_exporter --collector.textfile.directory /var/lib/node_exporter/textfile_collector  
  
[Install]  
WantedBy=multi-user.target  

Start script eos_exporter.sh.

This script collect metrics to text file. You need to set variables in eos_exporter.sh. You can use supervisor to start this script. To check Node Exporter use curl http://localhost:9100/metrics.
To get metrics for other cryptocurrencies you need create other scripts. For example bos_exporter.sh.

Import template to Grafana.

You can import template Nodes_metrics.json to Grafana using standard import procedure.
