Re: Kerberos on NagiosXI

I tried to login to Nagiosxi home page but its prompting for credentials Nagios XI has it's own back-end authentication system that supersedes the app/web server. I'm not sure this implementation is valid unless authentication within Nagios XI has changed dramatically in the past year. This looks l...

Re: Calling NagiosLog API from Java example

This calls the ElasticSearch API, which isn't super different from the Nagios Log Server API:

Re: Nagios unable to send email via sendmail

I have mailutils installed and when I do "which mail", I get the following: root@ftp:~# which mail /usr/bin/mail All this confirms is that the root user's shell has an appropriate link for the mail command to /usr/bin/mail . The Nagios Core daemon doesn't run in a shell and probably shoul...

Re: Empty dashboard

Ports below 1024 are considered "privileged" in Linux. Did you follow the Nagios Log Server specific documentation for addressing this?

Re: Lost retention.dat

Unless you happen to be running ndoutils, and that database hasn't been overwritten, I'm pretty sure that data is gone.

You could probably parse some of that information out from the Nagios logs, but converting it to a proper retention.dat file would be a pain.

Relevant documentation: https://assets.nagios.com/downloads/nagios-log-server/docs/Alerting-On-Log-Events-With-Nagios-Log-Server.pdf ElasticSearch documents don't really have a concept of "lines" though. You can't simple say "grab line 3 of the message" unless you've broken out e...

Re: Host is Down but service running OK-Nagios XI

Can anyone provide the reason how this is possible? It would 100% depend on how you specifically configured the checks as well as the plugins being used by your checks. A scenario: My host checks are using ICMP pings. My service checks are using check_nrpe. My network team begins blocking ICMP requ...
