checkForNodeError :: [(String, ERpcError a)] -> String -> Maybe RpcErrorSource
getInstanceInfo :: [(String, ERpcError RpcResultAllInstancesInfo)] -> Instance -> ERpcError (Maybe (InstanceInfo, Bool))Source
Retrieves the instance information if it is present anywhere in the all instances RPC result. Notes if it originates from the primary node. An error is delivered if there is no result, and the primary node is down.

Arguments
| :: Bool | Live queries allowed |
| -> ConfigData | The cluster config |
| -> [String] | The requested fields |
| -> [Instance] | The instance objects |
| -> IO [(Instance, Runtime)] |
