I just finished up a manual install of Nagios Log Server on a fresh CentOS 7 VM according to the official instructions. After configuring a couple of our other VMs to send log data to Nagios Log Server, I noticed that nothing was showing up in the UI.

It turns out Logstash is crashing when I try to launch it:

Any ideas?

Can you show me your java -version output?

Can you also share the contents of your /var/log/logstash/logstash.log file?

Posted: **Thu Aug 25, 2016 12:27 pm**

java -version:

Code: Select all

java version "1.7.0_111"
OpenJDK Runtime Environment (rhel-2.6.7.2.el7_2-x86_64 u111-b01)
OpenJDK 64-Bit Server VM (build 24.111-b01, mixed mode)

The logstash.log file is blank.

Do you know if your organization uses a custom repository for their Java distributions? This looks like something specific to the Java environment.

In the file /usr/local/nagioslogserver/logstash/bin/logstash.lib.sh

Around line 35 try adding the following line:

Code: Select all

JAVA_OPTS="$JAVA_OPTS -Djava.ext.dirs=/some/dummy/path"

Save the file and try to start the logstash service. Share a fresh copy of the relevant syslog information also.

No, no custom repositories.

I installed OpenJDK 1.8 from the official repositories, and it works now.

Problem solved.

Very strange. Thanks for sharing your solution though!

Is it alright if I lock this thread and mark the issue as resolved?
