49 hcheck is the cluster checker. It prints information about cluster's
50 health and checks whether a rebalance done using **hbal** would help.
52 This information can be presented in both human-readable and
55 Note that it does not take any action, only performs a rebalance
56 simulation if necessary.
58 For more information about the algorithm details check **hbal**\(1).
64 Only perform checks based on current cluster state, without trying
65 to simulate rebalancing.
67 For a detailed description about the options listed above have a look at
68 **htools**\(7), **hspace**\(1) and **hbal**\(1).
