Puppet dashboard shows all hosts unresponsive

[Karim]

Hi guys,

I have a strange situation. I've got 1 dashboard MySQL DB accessed from 3 different dashboard hosts. Strangely enough, 2 of them show the right node statuses, and the third one just shows all nodes as unresponsive.

As far as I know, the status comes from the "nodes" table in the DB, so how can this happen? Is there some cache I need to clear? Is there another source for this information?

Dashboard version is 1.2.5.

Thanks!

Karim

The actual display of unresponsive nodes in dashboard is indeed based on the last time a node ran, but it's controlled by a setting in dashboard's settings.yaml file. Not sure what you're on, but on centos, that would be /usr/share/puppet-dashboard/config/settings.yaml, and look for the no_longer_reporting_cutoff setting. If that's set too low, you'll get a lot of unresponsive nodes in dashboard.
