I have followed the following document and everything has worked up until 'Delete Removed Instance' section
https://assets.nagios.com/downloads/nag ... luster.pdf

This happens, and it wont delete

What version of NLS is this? What OS?

I'd like you to navigate to the page where the old node is seen and then run this on the command line:

Code: Select all

tail -f /var/log/httpd/*
and click the delete icon. Please provide anything that is generated in terminal when you take this action.

I'd also like to see a tcpdump taken while you do the same thing. This can be done with:

Code: Select all

yum -y install tcpdump
tcpdump -s 0 -i any -w output.pcap
Then click delete and use CTRL+C to stop it. You can PM me the log files as well as the output.pcap created by the tcpdump.

Finally, provide me with a copy of the nagioslogserver index and I'll be able to provide you commands to remove the entry from the command line. This can be exported to a file by running:

Code: Select all

curl -XPOST http://localhost:9200/nagioslogserver/_export?path=/tmp/nagioslogserver.tar.gz
The file it creates and that we'd like to see is /tmp/nagioslogserver.tar.gz.

Hi cdienger

NL 2.1.5
Centos 6.9

I have also tried clearing internet cache, and using different browsers, same error.

Here is a copy of all logs in /var/log/httpd/ while executing the command to remove the instance

The output and other tar.gz I will PM to you now.

Everything below have been sanitised, real server names and IP changed

Thank you

Thanks for the data. I'll look into the cause but in the meantime I've sent you a command to remove the node.
