Validators Monitoring

Prerequisites

First install Grafana (opens in a new tab) and Prometheus (opens in a new tab) on your machine.

Enable tendermint metrics

To enable metrics, you'll have to make an adjustment in the node's config.toml file by setting the prometheus option to true:

sed -i 's/prometheus = false/prometheus = true/g' /home/zetachain/.zetacored/config/config.toml

To apply the modification, it's necessary to restart the node. You should then have the capability to reach the tendermint metrics, which are set as the default on port port 26660: http://localhost:26660 (opens in a new tab)

Configure prometheus targets

Locate the prometheus.yml file and add the following job entry under the scrape_configs section:

- job_name: "zetachain"
  static_configs:
    - targets: ["localhost:26660"]
      labels:
        instance: "validator"

On Linux machines, you can typically find the prometheus.yml file at the following path: /etc/prometheus/prometheus.yml

Reload Prometheus and Restart Zetachain

Reload Prometheus configuration:

curl -X POST http://localhost:9090/-/reload

Restart Zetachain Node:

sudo systemctl restart zetacored

Configure Grafana

By default, Grafana usually runs on port 3000. You can access Grafana by navigating to the following URL: http://localhost:3000.

The default username and password is admin.

Add your Prometheus Data Source:

Click on Save & test to test the configuration, if everything is alright you'll see the green message Data source is working.

Import grafana dashboard

Copy and paste the Grafana Dashboard ID (opens in a new tab) 11036 and click on Load to complete importing.

Select your Prometheus as Data Source and click Import.

At this point, you should be able to monitor your validator node.
