DESCRIPTION |
47 |
----------- |
48 |
|
49 |
hcheck is the cluster checker. It prints information about cluster's |
50 |
health and checks whether a rebalance done using **hbal** would help. |
51 |
|
52 |
This information can be presented in both human-readable and |
53 |
machine-readable way. |
54 |
|
55 |
Note that it does not take any action, only performs a rebalance |
56 |
simulation if necessary. |
57 |
|
58 |
For more information about the algorithm details check **hbal**\(1). |
59 |
|
60 |
OPTIONS |
61 |
------- |
62 |
|
63 |
\--no-simulation |
64 |
Only perform checks based on current cluster state, without trying |
65 |
to simulate rebalancing. |
66 |
|
67 |
For a detailed description about the options listed above have a look at |
68 |
**htools**\(1), **hspace**\(1) and **hbal**\(1). |
