Nexres Grafana Dashboard is a Grafana base dashboard for Nexres. It aims to provide a simple real-time interface for developers to monitor and diagnose Nexres. The data is stored in the Prometheus time-series database and queried by Grafana using PromeQL. The system usage data is provided by Prometheus third-party exporter Node Exporter.

Requirements

Using Nexres dynamic dashboard requires the installation of Prometheus, Node Exporter, Prometheus-cpp, and Grafana. It has been successfully tested with Bazel building in C++17 on Ubuntu 20.04.4 LTS (Windows 11 WSL) and Visual Studio Code.

Installation

Install Prometheus

go to https://prometheus.io/download/ download prometheus

tar xvfz (your-prometheus-tar-file)

Install node_exporter

go to https://github.com/prometheus/node_exporter download the lastest version of node_exporter from release

tar xvfz (your-node-exporter-tar-file)

Install grafana

wget -q -O - https://packages.grafana.com/gpg.key | sudo apt-key add -
sudo add-apt-repository "deb https://packages.grafana.com/oss/deb stable main"
sudo apt update 
sudo apt install grafana

Start grafana

sudo service grafana-server start
sudo service grafana-server enable

Default grafana port is 3000

Start the dashboard

Prometheus

Default prometheus port is 9090

./prometheus

Node_exporter

Default node exporter port is 9100

./node_exporter

Local Test

  1. Change the exporter endpoint from the prometheus config (example) to the localhost:port port number can be found from the script (e.g. 8090)

  2. Start prometheus, grafana, and node_exporter

  3. Start the KV service using the script: service/tools/kv/server_tools/start_kv_service_monitoring.sh

  4. Open the prometheus to check the service status: http://localhost:9090/targets?search=

  5. Set up your grafana dashboard from http://locahost:3000/ A grafana dashboard template can be found here.

Remote Deploy

  1. Set the exporter endpoint from the prometheus config with each deploy node (example)

  2. Set node_exporter in each of the deploy node

  3. Set the grafana export point in the deploy script scripts/deploy/script/deploy.sh#L21

  4. Deploy the nodes
