nexellia-stratum-bridge

Nexellia Stratum Adapter

This is a lightweight daemon that allows mining to a local (or remote) Nexellia node using stratum-base miners.

This daemon is confirmed working with the miners below in both dual-mining and Nexellia-only modes (for those that support it) and Windows, Linux, macOS and HiveOS.

Features

Shares-based work allocation with miner-like periodic stat output:

Grafana UI

The grafana monitoring UI is an optional component but included for convenience. It will help to visualize collected statistics.

detailed instructions here

Many of the stats on the graph are averaged over a configurable time period (24hr default - use the 'resolution' dropdown to change this), so keep in mind that the metrics might be incomplete during this initial period.

Prometheus API

If the app is run with the -prom={port} flag the application will host stats on the port specified by {port}, these stats are documented in the file prom.go. This is intended to be use by prometheus but the stats can be fetched and used independently if desired. curl http://localhost:2114/metrics | grep kls_ will get a listing of current stats. All published stats have a kls_ prefix for ease of use.

Install

Build from source (native executable)

Install go 1.18 using whatever package manager is appropriate for your system.

cd cmd/nexelliabridge
go build .

Modify the config file in ./cmd/nexelliabridge/config.yaml with your setup, the file comments explain the various flags.

./nexelliabridge

To recap the entire process of initiating the compilation and launching the nexellia dridge, follow these steps:

cd cmd/nexelliabridge
go build .
./nexelliabridge

Docker (all-in-one)

Best option for users who want access to reporting, and aren't already using Grafana/Prometheus. Requires a local copy of this repository, and docker installation.

Install Docker using the appropriate method for your OS. The docker commands below are assuming a server type installation - details may be different for a desktop installation.

The following will run the bridge assuming a local nexelliad node with default port settings, and listen on port 5555 for incoming stratum connections.

git clone https://github.com/GRinvestPOOL/nexellia-stratum-bridge.git
cd nexellia-stratum-bridge
docker compose -f docker-compose-all-src.yml up -d --build

These settings can be updated in the config.yaml file, or overridden by modifying, adding or deleting the parameters in the command section of the docker-compose-all-src.yml file. Additionally, Prometheus (the stats database) and Grafana (the dashboard) will be started and accessible on ports 9090 and 3000 respectively. Once all services are running, the dashboard should be reachable at http://127.0.0.1:3000/d/x7cE7G74k1/klsb-monitoring with default username and password admin.

These commands builds the bridge component from source, rather than the previous behavior of pulling down a pre-built image. You may still use the pre-built image by replacing docker-compose-all-src.yml with docker-compose-all.yml, but it is not guaranteed to be up to date, so compiling from source is the better alternative.

Docker (bridge only)

Best option for users who want docker encapsulation, and don't need reporting, or are already using Grafana/Prometheus. Requires a local copy of this repository, and docker installation.

Install Docker using the appropriate method for your OS. The docker commands below are assuming a server type installation - details may be different for a desktop installation.

The following will run the bridge assuming a local nexelliad node with default port settings, and listen on port 5555 for incoming stratum connections.

git clone https://github.com/GRinvestPOOL/nexellia-stratum-bridge.git
cd nexellia-stratum-bridge
docker compose -f docker-compose-bridge-src.yml up -d --build

These settings can be updated in the config.yaml file, or overridden by modifying, adding or deleting the parameters in the command section of the docker-compose-bridge-src.yml

These commands builds the bridge component from source, rather than the previous behavior of pulling down a pre-built image. You may still use the pre-built image by issuing the command docker run -p 5555:5555 nexellianetwork/nexellia_bridge:latest, but it is not guaranteed to be up to date, so compiling from source is the better alternative.
