I'm struggling to get good results from Thanos queries for large amounts of history, e.g. a "last 90 days" view on the Host overview dashboard:
A few of the graph panels load, but only a few.
The error message shown in the hover is <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>503 Service Unavailable</title> </head><body> <h1>Service Unavailable</h1> <p>The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.</p> </body></html> which looks like a minimal boilerplate 503, not sure exactly where it's coming from, although I suspect internally generated in grafana after some failure in talking to Thanos?
