Timo reported that we have the following issues on PANIC Prod:

• Arbitrum, Avalanche (evm node monitors), Tgrade and E-money (cosmos node monitors), zeitgeist (substrate system monitor) failures are failing and restarting all the time.
• Slack error:

alerter_1 | Failed to send a request to Slack API server: <urlopen error [Errno -3] Temporary failure in name resolution>

For chains issue:

• Go on the panic installer hosted on the panicprod vm and add nodes for the mentioned chains
• sudo docker-compose logs -f alerter and check out the alerter logs to see the issues as they come in

For slack issue:

• Perform sudo docker-compose logs -f alerter on the vm
