You probably have something like:
```auto
ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
127.0.0.1 19 97 17 2.17 mdi * Iv2LGj-
```
The name is `Iv2LGj` in my case. I guess that in your case it's something like `2XK4x5`?

Actually `2XK4x5 **** ` is not a node id. It looks like a parent task id here.
The node is `Qb03E91zSCG1tBvhmfWqzg` which in your case is:
```auto
Qb03 10.11.10.xx
```
