Failed to flush output scrolling in logstash log

[dworthcsl]

Hi,

I just upgraded to 2015R2.1 running on RHEL 7.1. I am getting the following scrolling in logstash log. Everything looks healthy in admin. Any help would be appreciated.

Code: Select all

it looks like the issue was the wrong cluster uuid in the 999_outputs.cfg. I updated it on the node with the scrolling messages and errors stopped scrolling.

Will this update get over written in the config?

dworthcsl,

No sir - the update that you've made to the outputs file should be persistent. I just submitted a bug that details the following issue:

When a node is added to a cluster, initially the wrong UUID is set in the logstash 999_outputs.conf file. This is resolved by either changing that output file manually or running a single 'Apply Configuration' from the Web GUI.

Best,
