Nagios Support Forum

Same setup as in my other thread: https://support.nagios.com/forum/viewto ... 71#p301982

Nagios Log Server Cluster:
Have added System Profiles from both systems as attachments.

iganagioslog - CentOS release 6.10 (Final)
This is the first system setup when we started using NLS, I believe it was a VMware image from Nagios.
NLS 2.1.3

iganagioslog01 - Red Hat Enterprise Linux Server release 7.7 (Maipo)
Install from downloaded tar file.
Getting the following errors in the logstash log:

Ports below 1024 are privileged and require additional setup on each of the servers in your cluster.

We have a document outlining the procedure

Hmmm Ok, I'll have to take a look at the configs, didn't think I had anything on that port.

Ya, looks like there must be one configured for 514

Code: Select all

protocol=>:tcp, :address=>"0.0.0.0:514",

Found it, thanks. I'll have them change the port sending to if I can, for now just started the system as root as a temp fix.

Thanks
