eth2-grafana

Grafana dashboards for Prysmatic Labs Prysm Eth2 client.

Host stats require node_exporter, ping stats require blackbox_exporter, and ETH price requires blackbox_exporter. Panels requiring these modules can be manually removed from the dashboard after installation if you choose not to install these additional components.

High Level Installation

This installation assumes that you are running Prysm, Grafana, Prometheus, node_exporter, blackbox_exporter, and json_exporter on the same system, and that only default ports are used.

1. Install node_exporter if you would like to see system information, such as CPU utilization, memory use, CPU temperature, disk usage, and network traffic.
2. If you would like to see ping (network latency) information, install blackbox_exporter using the following configuration file.

modules:         icmp:                 prober: icmp                 timeout: 10s                 icmp:                         preferred_ip_protocol: ipv4 

3. Install go
4. Install json_exporter if you would like to see ETH price information. Use the following configuration file.

metrics: - name: ethusd   path: $.ethereum.usd   help: Ethereum (ETH) price in USD 

5. Install Prometheus using the following configuration file.

8. Add the Prysm dashboard to Grafana.

Detailed Ubuntu 20.04 Installation

Adapted from my instructions for setting up a Prysm staking system on Ubuntu 20.04.

Prometheus

Create User Account

sudo adduser --system prometheus --group --no-create-home

Install Prometheus

Find the URL to the latest amd64 version of Prometheus at https://prometheus.io/download/. In the commands below, replace any references to the version 2.22.1 to the latest version available.

cd wget https://github.com/prometheus/prometheus/releases/download/v2.22.1/prometheus-2.22.1.linux-amd64.tar.gz tar xzvf prometheus-2.22.1.linux-amd64.tar.gz cd prometheus-2.22.1.linux-amd64 sudo cp promtool /usr/local/bin/ sudo cp prometheus /usr/local/bin/ sudo chown root:root /usr/local/bin/promtool /usr/local/bin/prometheus sudo chmod 755 /usr/local/bin/promtool /usr/local/bin/prometheus cd rm prometheus-2.22.1.linux-amd64.tar.gz

Configure Prometheus

Create directories that prometheus will be expecting to find.

sudo mkdir -p /etc/prometheus/console_libraries /etc/prometheus/consoles /etc/prometheus/files_sd /etc/prometheus/rules /etc/prometheus/rules.d

Create the prometheus configuration files. Open a new configuration file.

sudo nano /etc/prometheus/prometheus.yml

Copy and paste the following text into the prometheus.yml configuration file:

global:   scrape_interval: 15s  scrape_configs:   - job_name: 'prometheus'     scrape_interval: 5s     static_configs:     - targets: ['127.0.0.1:9090']   - job_name: 'beacon node'     scrape_interval: 5s     static_configs:     - targets: ['127.0.0.1:8080']   - job_name: 'node_exporter'     scrape_interval: 5s     static_configs:     - targets: ['127.0.0.1:9100']   - job_name: 'validator'     scrape_interval: 5s     static_configs:     - targets: ['127.0.0.1:8081']   - job_name: 'ping_google'     metrics_path: /probe     params:       module: [icmp]     static_configs:       - targets:         - 8.8.8.8     relabel_configs:       - source_labels: [__address__]         target_label: __param_target       - source_labels: [__param_target]         target_label: instance       - target_label: __address__         replacement: 127.0.0.1:9115  # The blackbox exporter's real hostname:port.   - job_name: 'ping_cloudflare'     metrics_path: /probe     params:       module: [icmp]     static_configs:       - targets:         - 1.1.1.1     relabel_configs:       - source_labels: [__address__]         target_label: __param_target       - source_labels: [__param_target]         target_label: instance       - target_label: __address__         replacement: 127.0.0.1:9115  # The blackbox exporter's real hostname:port.   - job_name: json_exporter     static_configs:     - targets:       - 127.0.0.1:7979   - job_name: json     metrics_path: /probe     static_configs:     - targets:       - https://api.coingecko.com/api/v3/simple/price?ids=ethereum&vs_currencies=usd     relabel_configs:     - source_labels: [__address__]       target_label: __param_target     - source_labels: [__param_target]       target_label: instance     - target_label: __address__       replacement: 127.0.0.1:7979 

Note: Users of earlier versions of these instructions may have the beacon node job name set to “beacon” instead of “beacon node”. When choosing a Grafana dashboard from this repository, please select this dashboard if you are using “beacon” as the job name, and this dashboard if you are using “beacon node” as the job name.

Change the ownership of the prometheus configuration directory to the prometheus user.

sudo chown -R prometheus:prometheus /etc/prometheus

Data Directory

Make a directory for prometheus files, owned by the prometheus user account, and with appropriate privileges.

sudo mkdir /var/lib/prometheus sudo chown prometheus:prometheus /var/lib/prometheus sudo chmod 755 /var/lib/prometheus

Set Up systemd Service

Set up systemd to automatically start Prometheus. It will also restart the software if it stops.

sudo nano /etc/systemd/system/prometheus.service

Copy and paste the following text into the prometheus.service file.

[Unit] Description=Prometheus Wants=network-online.target After=network-online.target  [Service] User=prometheus Group=prometheus Type=simple Restart=always RestartSec=5 ExecStart=/usr/local/bin/prometheus      --config.file /etc/prometheus/prometheus.yml      --storage.tsdb.path /var/lib/prometheus/      --web.console.templates=/etc/prometheus/consoles      --web.console.libraries=/etc/prometheus/console_libraries  [Install] WantedBy=multi-user.target 

Reload the systemd service file configurations, start prometheus, then enable the prometheus service to have it start automatically on reboot.

sudo systemctl daemon-reload sudo systemctl start prometheus.service sudo systemctl enable prometheus.service

Grafana

Setup and install Grafana using apt-get.

cd sudo apt-get install -y apt-transport-https sudo apt-get install -y software-properties-common wget wget -q -O - https://packages.grafana.com/gpg.key | sudo apt-key add - sudo add-apt-repository "deb https://packages.grafana.com/oss/deb stable main" sudo apt-get update sudo apt-get install grafana-enterprise

Setup systemd

Reload the systemd service file configurations, start Grafana, then enable the Grafana service to have it start automatically on reboot.

sudo systemctl daemon-reload sudo systemctl start grafana-server sudo systemctl enable grafana-server

Login to Grafana at http://XXX.XXX.XXX.XXX:3000/, replacing XXX.XXX.XXX.XXX with the IP address of your server. If you do not know the IP address, run ifconfig.

Default username admin. Default password admin. Grafana will ask you to set a new password.

Setup Prometheus Data Source

1. On the left-hand menu, hover over the gear menu and click on Data Sources.
2. Then click on the Add Data Source button.
3. Hover over the Prometheus card on screen, then click on the Select button.
4. Enter http://127.0.0.1:9090/ into the URL field, then click Save & Test.

Install Grafana Dashboard

1. Hover over the plus symbol icon in the left-hand menu, then click on Import.
2. Copy and paste the dashboard at https://raw.githubusercontent.com/metanull-operator/eth2-grafana/master/eth2-grafana-dashboard-single-source-beacon_node.json into the “Import via panel json” text box on the screen. If you used an older version of these instructions, where the Prometheus configuration file uses the beacon node job name of “beacon” instead of “beacon node”, please use this dashboard instead for backwards compatibility.
3. Then click the Load button.
4. Then click the Import button.

Note: Some panels will not display data until all required software is running. Various portions of this dashboard are directly or indirectly dependent on Prometheus, Prysm beacon chain, Prysm validator, node_exporter, and blackbox exporter.

Final Grafana Dashboard Configuration

A few of the queries driving the Grafana dashboard may need different settings, depending on your hardware.

Network Traffic Configuration

To ensure that network traffic is correctly reflected on your Grafana dashboard, update the network interface in the Network Traffic widget. Run the following command to find your Linux network device.

ifconfig

Output of the command should look like the following:

eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500         inet 192.168.1.10  netmask 255.255.255.0  broadcast 192.168.1.255         inet6 fe80::1e69:7aff:fe63:14b0  prefixlen 64  scopeid 0x20<link>         ether 1c:69:7a:63:14:b0  txqueuelen 1000  (Ethernet)         RX packets 238936  bytes 78487335 (78.4 MB)         RX errors 0  dropped 1819  overruns 0  frame 0         TX packets 257824  bytes 112513038 (112.5 MB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0         device interrupt 16  memory 0x96300000-96320000  lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536         inet 127.0.0.1  netmask 255.0.0.0         inet6 ::1  prefixlen 128  scopeid 0x10<host>         loop  txqueuelen 1000  (Local Loopback)         RX packets 39805  bytes 29126770 (29.1 MB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 39805  bytes 29126770 (29.1 MB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 

Of the two entries shows above, the first lists my IP address on the second line, network interface eno1. Find the entry that represents the network connection you want to monitor and copy the device name, which is the part before the colon on the first line of each entry. In my case the value is eno1.

1. Go to the Grafana dashboard previously installed
2. Find the Network Traffic widget, and open the drop down that can be found by the Network Traffic title.
3. Click Edit.
4. There will be four references to eno1 in the queries that appear. Replace all four with the name of the network interface you found in the ifconfig command.

node_exporter

Node exporter allows Prometheus to record system data, such as CPU utilization, memory use, CPU temperature, and disk usage.

Setup and install node_exporter using apt-get.

Create User Account

sudo adduser --system node_exporter --group --no-create-home

Install node_exporter

cd wget https://github.com/prometheus/node_exporter/releases/download/v1.0.1/node_exporter-1.0.1.linux-amd64.tar.gz tar xzvf node_exporter-1.0.1.linux-amd64.tar.gz sudo cp node_exporter-1.0.1.linux-amd64/node_exporter /usr/local/bin/ sudo chown node_exporter:node_exporter /usr/local/bin/node_exporter rm node_exporter-1.0.1.linux-amd64.tar.gz

Set Up System Service

Set up systemd to automatically start node_exporter. It will also restart the software if it stops.

Reload the systemd service file configurations, start node_exporter, then enable the json_exporter service to have it start automatically on reboot.

sudo systemctl daemon-reload sudo systemctl start json_exporter.service sudo systemctl enable json_exporter.service

Optional

blackbox_exporter

I use blackbox_exporter to provide ping (network latency) data between my staking system and two DNS providers. This can also be used to see network downtime.

The Grafana dashboard in these instructions includes a panel with a ping time graph. If you choose not to install blackbox_exporter, simply remove that panel from your Grafana dashboard. It will not show data.

Create User Account

sudo adduser --system blackbox_exporter --group --no-create-home

Install blackbox_exporter

cd wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.18.0/blackbox_exporter-0.18.0.linux-amd64.tar.gz tar xvzf blackbox_exporter-0.18.0.linux-amd64.tar.gz sudo cp blackbox_exporter-0.18.0.linux-amd64/blackbox_exporter /usr/local/bin/ sudo chown blackbox_exporter:blackbox_exporter /usr/local/bin/blackbox_exporter sudo chmod 755 /usr/local/bin/blackbox_exporter

Gives blackbox_exporter special network packet creation abilities to allow for pinging servers.

sudo setcap cap_net_raw+ep /usr/local/bin/blackbox_exporter

Remove the original blackbox_exporter package.

rm blackbox_exporter-0.18.0.linux-amd64.tar.gz

Configure blackbox_exporter

sudo mkdir /etc/blackbox_exporter sudo chown blackbox_exporter:blackbox_exporter /etc/blackbox_exporter

Edit the blackbox_exporter configuration file.
