Consensus and Collection Node Operators,

The Flow Node software now includes additional metrics to help manage Machine Accounts.

Machine Accounts are Flow accounts controlled by the node software and used to send transactions as part of the epoch protocol. (You can find more details in the docs: Machine Account | Flow Developer Portal).

The new metrics help track Machine Account balances.

We highly recommend setting up alerts for the following conditions:

  1. When the machine account balance needs to be funded with additional FLOW:

machine_account_balance < machine_account_recommended_min_balance

  1. When the machine account has a configuration error:

machine_account_is_misconfigured > 0

The full documentation for these metrics can be found here: Monitoring Node Health | Flow Developer Portal

Thank you,
Flow Foundation

If the machine account is misconfigured, (machine_account_is_misconfigured > 0) the node will log detailed log message about what is wrong. The log message will have the substring machine_account_config_validator.
