error while reading config.toml: Config File \"config\" Not Found

[Throbac-Labs]

Having an issue with running the solana_mc.service

It looks like the service cannot locate my config.toml when the execution begins.

here's the error:

Apr 12 18:10:13 solana2 solana-mc[219813]: time="2022-04-12T18:10:13Z" level=fatal msg="error while reading config.toml: Config File \"config\" Not Found in \"[/ /home/$USER/.solana-mc/config]\""

here's the systemd file located in /lib/systemd/system/solana_mc.service:

[Unit]
Description=Solana-mc

[Install]

Current solana-mc script was built using:

 $ go build -o /home/$USER/go/bin/solana-mc 

and my config.toml

The script works just fine when i type "solana-mc" into the command prompt, and I see metrics in grafana via prometheus.

I examined the config.go file within the repos config directory and see where the error is coming from, but I am still unsure where & exactly what i need to do to fix the config path error.

Things i tried:

• cp example.config.toml /home/$USER/config.toml -- to create config.toml in the /home/user location
• export CONFIG_PATH="/home/$USER"
• tried adding a --config flag to the exec function inside the systemd file
• tried using the repo path for the exec "/home/monitoring/solana-mission-control/solana-mc"
  • used this when i built the go script "solana-=mc" inside this repo

Running Ubuntu 20.04 with a validator on Solana Devnet.

Any help is appreciated!

UPDATE:

Was able to solve by adding a "Working Directory" variable to the /lib/systemd/system/solana_mc.service

[Unit]
Description=Solana-mc
After=network-online.target

[Service]
User=$USER 
Environment="SOLANA_BINARY_PATH=/home/sol/.local/share/solana/install/active_release/bin/solana"
WorkingDirectory=/home/$USER
ExecStart=/home/$USER/go/bin/solana-mc 
Restart=always
RestartSec=3
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target

Might be worth adding to the repo, def a little confusing trying to make sure the service can access the necessary config. I was not able to get 'export CONFIG_PATH="/home/$USER"' to work. I'm sure I'm missing something, but hopefully this helps others!
