Hi, hope i can find answer here.
I’m using prometheus+grafana to monitor my system. It ran well before today. In the morning, I find grafana cannot show data/trend. On each panel ,there is one red “!” and the erros msg is that " cannot read property ‘result’ of undefined". I didn’t make any change on prometheus and grafana! It just happend.
At this time, prometheus works well. I can search the tag and get the trend in prometheus.
The version of prometheus is: 2.0.0, and grafana is 4.6.2.
Can anyone help?
Thanks a lot.
