settings: do not query ES for settings in non-green status #9308
Conversation
If the ui settings status is not green, that means there is at least one dependency (so elasticsearch at the moment) that is not met in order for it to function correctly, so we shouldn't attempt to determine user settings at all. This ensures that when something like the version check fails in the elasticsearch plugin, Kibana correctly behaves by not attempting requests to elasticsearch, which prevents 500 errors and allows users to see the error status on the status page. We also now periodically check for compatible elasticsearch versions so that Kibana can automatically recover if the elasticsearch node is upgraded to the appropriate version.

is waitForPong needed if we are pinging during the version check now? I don't think this should block, worth taking a look at later.
@jbudz That's a thought. I don't know what the ramifications would be for removing the waiting behaviors, but I think we should do it consistently. So either they all wait or they all don't wait. I'll create a separate issue for it |

These changes LGTM, though I was unable to actually reproduce the error noted in the issue. (es 5.0.1 and kibana 5.1.1 all with x-pack)
@tylersmalley That's interesting... I didn't have to do anything special to get the 500 error to reproduce. |

If the ui settings status is not green, that means there is at least one
dependency (so elasticsearch at the moment) that is not met in order for
it to function correctly, so we shouldn't attempt to determine user
settings at all.
This ensures that when something like the version check fails in the
elasticsearch plugin, Kibana correctly behaves by not attempting
requests to elasticsearch, which prevents 500 errors and allows users to
see the error status on the status page.
We also now periodically check for compatible elasticsearch versions so
that Kibana can automatically recover if the elasticsearch node is
upgraded to the appropriate version.
