Hi @ovi ,
I think what your reporting is related to this [Bug]: Lost the possiblity to see individual charts on Single Node view · Issue #654 · netdata/netdata-cloud · GitHub
Now the charts even on Single Node view are context level charts, if you want to see the specific details on the specific devices you need to change the group by option on the chart
After the change the charts shows 7 devices
Please let us know if this worked for you.
Regards,
Hugo
