[Question] About "cluster health" command.

Hi All,

After a cluster started in a single node, I executed "cluster health" command.

```
[root@rh73-01-crmsh ~]# crm_mon -1 -Af
Stack: corosync
Current DC: rh73-01-crmsh (version 1.1.15-11.el7_3.2-e174ec8) - partition with quorum

Log patterns:

WARNING: rh73-01-crmsh: No log rotation configured for corosync.conf

```

After having executed a command, "health-report" was made nowhere.

```
[root@rh73-01-crmsh ~]# find / -name health-report -print

```

After having executed a command with d option, "health-report" was made.
Is the difference in this movement right?
```
[root@rh73-01-crmsh ~]# crm -d cluster health
