Nagios Log Server - Logstash not running after upgrade to 2.0

Overview

After upgrading to Nagios Log Server 2.0, the logstash service doesn't remain running.

 

Diagnosis

The /var/log/logstash/logstash.log file will show a message similar to:

{:timestamp=>"2017-11-14T08:24:17.314000-0700", :message=>"Pipeline aborted due to error", :exception=>"LogStash::
ConfigurationError", :error=>"The setting `host` in plugin `elasticsearch` is obsolete and is no longer available. Please use the 'hosts' setting
 instead. You can specify multiple entries separated by comma in 'host:port' format. If you have any questions about this, you are invited to
visit https://discuss.elastic.co/c/logstash and ask.", :backtrace=>

 "/usr/local/nagioslogserver/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.1-java/lib/logstash/agent.rb:491:in `start_pipeline'"],
:level=>:error}

 


 

Problem

Logic in the initially released upgrade script didn't allow logstash config files to be rewritten correctly.

 

 

Solution

The upgrade script has been updated and a new download of the 2.0 software resolves the problem.

It can also be resolved by running the following command in a terminal session as the root user:

/usr/bin/php /var/www/html/nagioslogserver/www/index.php configure/write_configs_for_node

 

This command needs to be executed on each instance in your Nagios Log Server Cluster.
