It prints information about cluster's health and checks whether a rebalance done using **hbal** would help. This information can be presented in both human-readable and machine-readable way. Note that it does not take any action, only performs a rebalance simulation if necessary. For more information about the algorithm details check **hbal**\(1). OPTIONS ------- \--no-simulation Only perform checks based on current cluster state, without trying to simulate rebalancing. For a detailed description about the options listed above have a look at **htools**\(1), **hspace**\(1) and **hbal**\(1). .. vim: set textwidth=72 : ..
