I was trying to do that; but I cannot find the correct widget?
Turns out all three broken graphs are rendering the aggregate traffic (those interfaces with "Transit" in their description) just the scale varies: "one day", "one week", and "one month" 

When I go to "Add widget", in the traffic section, I only see "Top N" and "Traffic Composition". Not sure what it ought to be called, but there is nothing like "total throughput" or "aggregate graph"; so I can't add yet another example to see what happens.

I deleted one of the 3 broken RRD thinking that maybe it would then reappear in the "add widget" box; but that is not the case.

So I added a traffic comparison widget. And it's also refusing to render with the message "No Auth"

Does that graph work if you recreate it as a new widget?

After studying some more, the device RRD errors are only appearing on a few of the devices and they all have snmp errors (not an Observium problem); so lets forget about that report (they did use to just render blank). 

However, on the default dashboard is refusing to render graphs:

I don't honestly remember what renders in these 3 blocks; but one of them is the aggregate throuput gathered from all the ifdesc labeled with "Transit".

I’m not really sure we’ve changed much that should affect this.

Which graphs specifically?

You’ll often need to shift-refresh after an svn up to clear cached javascript, but that shouldn’t affect the graph auth, because that’s just checking you’re allowed to view those devices/entities, which is immediately short-circuited if you’re a global-view or admin user anyways.

Just finished an update that was a bit overdue (523 --> 540) and now I'm
getting various errors while rendering RRD:

"Draw Error"
"ERROR: can not parse an empty rpn expression"
"RRDTool seems to have generated an empty graph. Please ensure that RRDs
are being populated for this device."

While at the same time, some RRDs do render correctly.

On the dashboard the message is different:

"Permission error
You have insufficient permissions to view this page"

The poller runs as user:group "observium:obervium"
I have run "chown -R observium:observium /opt/observium" out of
paranoia, but it didn't help.

What am I missing?

Thanks for your time.
