### Checking cluster health for maintenance

You may query the cluster probe endpoint to check if the node which received the request can be taken down for maintenance, if the server replies back '412 Precondition Failed' this means you will lose HA. '200 OK' means you are okay to proceed.

```

its face to see what was the matter with it.  There could be no
doubt that it had a VERY turn-up nose, much more like a snout
than a real nose; also its eyes were getting extremely small for
a baby:  altogether Alice did not like the look of the thing at
all.  `But perhaps it was only sobbing,' she thought, and looked
