Telemetry Setup Instructions for Heimdall (Mumbai Nodes)

Polygon Testnets Mumbai Testnet
1

These are the instructions to setup telemetry for heimdall to monitor the nodes in https://heimdall-mumbai.vitwit.com/

  1. Clone and setup the config
git clone https://github.com/vitwit/matic-telemetry.git
cd matic-telemetry
mkdir -p ~/.telemetry/var/lib/heimdalld/config
cp example.config.toml ~/.telemetry/var/lib/heimdalld/config/config.toml
  1. Update the config for your node located in ~/.telemetry/var/lib/heimdalld/config/config.toml Update the [stats_details] block in config.Secret key and net stats ip will remain same as mentioned below. Update the node key with the name of your node.
[stats_details]
secret_key = "heimdall_testnet"
node = "<node-name>" 
net_stats_ip = "heimdall-mumbai.vitwit.com:3000"

Please use the following naming convention for node name:

3.*<entity_name>-<network_name>–<unique_identifier>**Eg:

  • vitwit-mumbai-sentry-ip10_0_0_1
  • infura-mumbai-explorer-1unique_identifier is just an identifier for you to distinguish between different nodes you are running (if you have multiple nodes).
  1. Build the binary (from the matic-telemetry directory)
go mod tidy
go build -o telemetry
mv telemetry $GOBIN
  1. Create a service (You can use a different service name to resolve conflicts with your local system if any. If you do so, make sure you use that name in subsequent commands below)
echo "[Unit]
Description=Telemetry
After=network-online.target
[Service]
User=$USER
ExecStart=$(which telemetry)
Restart=always
RestartSec=3
LimitNOFILE=4096
[Install]
WantedBy=multi-user.target" | sudo tee "/lib/systemd/system/telemetry.service"
  1. Start the telemetry service
sudo systemctl enable telemetry.service
sudo systemctl start telemetry.service
  1. You can monitor the service using journalctl. If everything works well, it should start exporting metrics.
journalctl -u telemetry -f
  1. Ensure that your node name is listed in https:// heimdall-mumbai.vitwit.com
