To use this feature, you need to have LiquidOps enabled with agent version 0.2.0 or higher or enrolled with macaroons.
Channel balance checks perform constant monitoring of your channels´ liquidity and report when the liquidity falls below a certain level. The liquidity is the available balance that can be sent across the channel in one direction as reminded here below (source lnbook)
Liquidity(NodeA) = balance(NodeA) - channel_reserve(NodeA) - pending_HTLCs(NodeA)
The channel i_nbound liquidity_ is the amount of bitcoin that a node can receive through that channel.
The channel o_utbound liquidity_ is the amount of bitcoin that a node can send through that channel.
Note: We make a difference between the inbound/outbound liquidity at a channel level and at a node level. The inbound/outbound liquidity of a node will be the sum of inbound/outbound liquidity of all its channels and can be monitored with node-balance.md trigger.
The channel balance trigger can be configured by selecting 2 parameters :
Liquidity type: Inbound or Outbound
Threshold: expressed in %
