Sometimes at HA startup a Netdata integration fails to create sensors.
Checking an availability of a corresponding Netdata node (like curl -X GET "http://SOME_IP:19999/api/v1/data?chart=disk_space._&points=2&options=jsonwrap") is OK.
Restarting a Netdata container on the corr. node does not help.
The only way to restore a connection is to reboot HA.
Is it supposed to work like this?
Is there any way to reload Netdata integration?
This is happening to me as well.
Right now I have to keep reloading Home Assistant until eventually they all work. Then it’s fine until I have to restart it at a later date, such as for updates.
Still no love for the netdata integration?
It’s not even possible to create more or change sensors through reloading the whole YAML configuration.
We still have to restart HA?
The countless “reload” services don’t seem to be made for this (or at least it’s not documented).
Or is using the netdata integration considered riding a dead horse?
The Netdata integration was introduced in Home Assistant 0.35, and it's used by 3 active installations.
Really?
I had the same intuition 
Maybe since there’s only 3 of us using this, there’s not a lot of love shown. I would love a reload feature for this integration for the same reasons above.
Probably a “reload” functionality will become available when the integration will be moved to UI.
But I do not appreciate a trend “move from yaml to UI”.
