Monitoring Validators

There is a Grafana dashboard compatible with all the cosmos-sdk and tendermint based blockchains.

Preview​

Let's set it up for our network.

Prerequisites​

First install Grafana and Prometheus on your machine.

Enable Tendermint Metrics​

sed -i 's/prometheus = false/prometheus = true/g' <YOUR-NODE-HOMEDIR>/config/config.toml

After restarting your node, you should be able to access the tendermint metrics(default port is 26660): http://localhost:26660

Configure Prometheus Targets​

Find prometheus.yml file and append the following job under the scrape_configs:

  - job_name: archway
    static_configs:
      - targets: ['localhost:26660']
        labels:
          instance: validator

Note: On linux machines this file can be found under this path: /etc/prometheus/prometheus.yml

Resolving Port Conflicts​

If you run your archway network and Prometheus on the same machine, you will see one of them cannot run due to a port conflict. Let's resolve it.

Open the ./node-main/config/app.toml file and look for

[grpc]
address = "0.0.0.0:9090"

Then change the port to something else like this:

[grpc]
address = "0.0.0.0:9095"

Restart Prometheus​

sudo service prometheus restart

Check the status if the prometheus service is running properly:

systemctl status prometheus.service

If you see some output like this, it means it is running without an issue:

● prometheus.service - Monitoring system and time series database
     Loaded: loaded (/lib/systemd/system/prometheus.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2021-10-06 15:32:48 CEST; 17min ago
       Docs: https://prometheus.io/docs/introduction/overview/

      Tasks: 21 (limit: 37746)
     Memory: 48.3M
     CGroup: /system.slice/prometheus.service
             └─457917 /usr/bin/prometheus

Configure Grafana​

if you have grafana installed on your machine, you can access it via navigating to this address: http://localhost:3000

The default username and password is admin.

Click on config, then add a data source.

Then select Prometheus from the list and add its URL.

If you have installed it on your machine, the default URL is: http://localhost:9090

Click on Save & test to make sure everything is alright.

Import Grafana Dashboard​

Copy and paste the Grafana Dashboard ID 11036 and click on Load to complete importing.

Now you should be able to monitor your validator node.
