Grafana Dashboard

There are several ways to monitor the performance of a Geth node. Insights into a node’s performance are useful for debugging, tuning and understanding what is really happening when Geth is running.


To follow along with the instructions on this page you will need:

  • a running Geth instance.
  • basic working knowlegde of bash/terminal.

This video provides an excellent introduction to Geth monitoring.

Monitoring stack

An Ethereum client collects lots of data which can be read in the form of a chronological database. To make monitoring easier, this data can be fed into data visualisation software. On this page, a Geth client will be configured to push data into a InfluxDB database and Grafana will be used to visualize the data.

Setting up InfluxDB

InfluxDB can be downloaded from the Influxdata release page. It can also be installed from a repository.

For example the following commands will download and install InfluxDB on a Debian based Linux operating system - you can check for up-to-date instructions for your operating system on the InfluxDB downloads page:

curl -tlsv1.3 --proto =https -sL | sudo apt-key add
source /etc/lsb-release
echo "deb${DISTRIB_ID,,} ${DISTRIB_CODENAME} stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
sudo apt update
sudo apt install influxdb -y
sudo systemctl enable influxdb
sudo systemctl start influxdb
sudo apt install influxdb-client

By default,InfluxDB it is reachable at localhost:8086. Before using the influx client, a new user with admin privileges needs to be created. This user will serve for high level management, creating databases and users.

curl -XPOST "http://localhost:8086/query" --data-urlencode "q=CREATE USER username WITH PASSWORD 'password' WITH ALL PRIVILEGES"

Now the influx client can be used to enter InfluxDB shell with the new user.

influx -username 'username' -password 'password'

A database and user for geth metrics can be created by communicating with it directly via its shell.

create database geth
create user geth with password choosepassword

Verify created entries with:

show databases
show users

Leave InfluxDB shell.


InfluxDB is running and configured to store metrics from Geth.

Preparing Geth

After setting up database, metrics need to be enabled in Geth. Various options are available, as documented in the METRICS AND STATS OPTIONS in geth --help and in our metrics page. In this case Geth will be configured to push data into InfluxDB. Basic setup specifies the endpoint where InfluxDB is reachable and authenticates the database.

geth --metrics --metrics.influxdb --metrics.influxdb.endpoint "" --metrics.influxdb.username "geth" --metrics.influxdb.password "chosenpassword"

These flags can be provided when Geth is started or saved to the configuration file.

Listing the metrics in the database verifies that Geth is pushing data correctly. In InfluxDB shell:

use geth
show measurements

Setting up Grafana

With the InfluxDB database setup and successfully receiving data from Geth, the next step is to install Grafana so that the data can be visualized.

The following code snippet shows how to download, install and run Grafana on a Debian based Linux system. Up to date instructions for your operating system can be found on the Grafana downloads page.

curl -tlsv1.3 --proto =https -sL | sudo apt-key add -
echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list
sudo apt update
sudo apt install grafana
sudo systemctl enable grafana-server
sudo systemctl start grafana-server

When Grafana is up and running, it should be reachable at localhost:3000. A browser can be pointed to that URL to access a visualization dashboard.

The browser will prompt for login credentials (use user: admin and password: admin). When prompted, the default password should be changed and saved.

The browser first redirects to the Grafana home page to set up the source data. Click on the “Data sources” icon and then click on “InfluxDB”. The following configuration options are recommended:

Name: InfluxDB
Query Language: InfluxQL

  URL: http://localhost:8086
  Access: Server (default)
  Whitelisted cookies: None (leave blank)

  All options left as their default (switches off)

Custom HTTP Headers

InfluxDB Details
  Database: geth
  User: <your-user-name>
  Password: <your-password>
  HTTP Method: GET

Click on “Save and test” and wait for the confirmation to pop up.

Grafana is now set up to read data from InfluxDB. Now a dashboard can be created to interpret and display it. Dashboards properties are encoded in JSON files which can be created by anybody and easily imported. On the left bar, click on the “Dashboards” icon, then “Import”.

For a Geth monitoring dashboard, copy the URL of this dashboard and paste it in the “Import page” in Grafana. After saving the dashboard, it should look like this:

Grafana 1


The dashboards can be customized further. Each panel can be edited, moved, removed or added. To learn more about how dashboards work, refer to Grafana’s documentation.

Some users might also be interested in automatic alerting, which sets up alert notifications that are sent automatically when metrics reach certain values. Various communication channels are supported.
