Dashboard data not showing


i have 4 graylog server nodes in a cluster.
on one of them i cannot see the dashboard data and instead i see “N/A”

How is the configuration of the problematic Graylog node different from the working Graylog nodes?


configuration is the same

What does that mean exactly?
What’s in the logs of the Graylog node and the Elasticsearch nodes at the time the problem is happening?
