zcashd_exporter

The zcashd_exporter will poll a zcashd node's rpc endpoint, retreive data, then preent it for prometheus to scrape.

Getting started locally

go get -v github.com/zcash-hackworks/zcashd_exporter
go install github.com/zcash-hackworks/zcashd_exporter
$GOPATH/bin/zcashd_exporter --help

Getting Started With docker-compose

Create zcashd direcotries

Decide where you want to store (or refence existing ) zcashd data.

For example, create 2 new directories:

sudo mkdir -p /srv/zcashd/.zcash
sudo mkdir -p /srv/zcashd/.zcash-params

Make uid 2001 owner of the directories. This is the uid of user zcashd runs as.

sudo chown -R 2001 /srv/zcashd/.zcash
sudo chown -R 2001 /srv/zcashd/.zcash-params

Create .env from .env.exmaple

cp .env.exmaple .env

Edit .env if you have any specific changes.

Install loki docker loging driver

docker plugin install  grafana/loki-docker-driver:latest --alias loki --grant-all-permissions

Start docker-compose

Start with

docker-compose up -d

Check that everything started

$ docker-compose ps
              Name                            Command               State                         Ports

zcashdexporter_zcashd_exporter_1   zcashd_exporter --rpc.host ...   Up      0.0.0.0:9100->9100/tcp  

Check status

zcashd

docker logs zcashd_exporter_zcashd_1

zcashd_exporter

docker logs zcashd_exporter_zcashd_exporter_1

If that's looking good, check prometheus for metric collection

http://localhost:9090/targets

If that looks good too, start querying

http://localhost:9090/graph

Start typing and metric names will auto-suggest
