Yeah, that is one file my server can still access and read, and it does reveal the RO status: /dev/mapper/ubuntu--vg-ubuntu--lv / ext4 ro,relatime,data=ordered 0 0 |

I have a server with Netdata installed which had it's root drive begin to fail, and so Ubuntu mounted the drive as read-only to avoid further corruption, which seems to be the default behavior of Ubuntu.
However, Netdata seems unable to determine anything about that and did not report to me what is occurring or flag the node as being in an error state.
Here is what it looks like, on the left in the terminal I am SSH'd into the node trying to diagnose the issue, on the right you can see that every individual chart is in an error state, but Netdata is not throwing any errors for the node as a whole.
I also am unable to access my nodes local dashboard whatsoever, hitting :19999 on the nodes internal IP gives me nothing, but works just fine for all my other nodes.
I feel that if a node does enter this state, somehow Netdata should be able to determine that, and probably flag it as a Red Error.
