Expected Behavior

If you run a widget on a dashboard and change the search relative time this should be propagated to all nodes.

Current Behavior

The search relative time is not set on all nodes instant. This leads to flipping widgets for different users that are not usable.

Possible Solution

Propagate the changed relative time via cluster event to all nodes in the cluster.

Steps to Reproduce

  1. Loadbalanced Graylog (two nodes behind a load balancer)
  2. Create a Dashboard Widget
  3. Load the Widget Configuration and change time relative time

Context

Having a Load balanced Environment of Graylog Nodes to shift the load of the Web Interface. No sticky connection let the people "jump" between the configured nodes. But every request is then served with the new (changed) relative time or the old that is not propagated to all nodes instant.

Your Environment

  • Graylog Version: 2.X

@dennisoelkers
Invalidating widget result cache cluster wide when a widget changes. 
Before this, a change to a widget done on one node was not reflected
correctly on other nodes, due to the widget being cached in the
WidgetResultsCache.

This change now creates and tracks widget update events cluster-wide and
invalidates the local caches accordingly.

Fixes #2732.
