ERROR: No active message processor! on nodes


On my three node setup two nodes arent processing messages. When i access them directly there is no pipeline processor in them showing this error:

ERROR: No active message processor!

How to enable them?

Part of my messages is not being processed in pipelines :frowning:

What’s the configuration of these Graylog nodes?
What’s in the logs of these Graylog nodes?

nothing connected to pipeline in server log

Please provide all the information I’ve asked for. Otherwise we’re unable to help you.


Graylog 2.3.2+3df951e on localhost (Oracle Corporation 1.8.0_131 on Linux 3.10.0-514.26.2.el7.x86_64)

rpm -Uvh
yum install graylog-server

Can You specify which part of log are You interested in? Need to get rid of sensitive data :frowning:

There is no ERROR type message in server log, I cant see any exceptions too

Everything from the first startup of Graylog.

Which plugins (with exact version string) are installed in your Graylog nodes?
You can check this in the web interface at System / Nodes / Details.


On the slave nodes:

This node has not any installed plugins.

On master node:

Anonymous Usage Statistics 2.3.2 Graylog, Inc. A plugin for collecting anonymous usages statistics about Graylog nodes and clusters. Website
Collector 2.3.2 Graylog, Inc. Collectors plugin Website
Elastic Beats Input 2.3.2 Graylog, Inc. Input plugin for Elastic Beats (Beats/Lumberjack protocol). Website
Enterprise Integration Plugin 2.3.2 Graylog, Inc Provides basic integration with Graylog Enterprise Website
MapWidgetPlugin 2.3.2 Graylog, Inc. Map widget for Graylog Website
Pipeline Processor Plugin 2.3.2 Graylog, Inc Pluggable pipeline processing framework Website

seems like this is the problem.

Had an error in plugin path. Fix + restart solved problems. Thx for help
