I try to deploy stx-monitor on 3 nworker nodes with label like this:

```
worker-3       Ready    <none>   2d18h   v1.16.2   beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,elastic-client=enabled,elastic-controller=enabled,elastic-data=enabled,elastic-master=enabled,kubernetes.io/arch=amd64,kubernetes.io/hostname=worker-3,kubernetes.io/os=linux
worker-4       Ready    <none>   2d18h   v1.16.2   beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,elastic-client=enabled,elastic-controller=enabled,elastic-data=enabled,elastic-master=enabled,kubernetes.io/arch=amd64,kubernetes.io/hostname=worker-4,kubernetes.io/os=linux
worker-5       Ready    <none>   2d16h   v1.16.2   beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,elastic-master=enabled,kubernetes.io/arch=amd64,kubernetes.io/hostname=worker-5,kubernetes.io/os=linux
```
When I check logs:

```

What mean the error above?
I just want to know, is stx-monitor stable or still experimental? Because I could not found documentation about it.
