DESCRIPTION

-----------

hcheck is the cluster checker. 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**\(7), **hspace**\(1) and **hbal**\(1).
