INSTALLATION ERROR!
===================
Installation step failed - exiting.
Check for error messages in the install log (install.log).

If you require assistance in resolving the issue, please include install.log
in your communications with Nagios Enterprises technical support.

The step that failed was: 'prereqs'

[mcapra]

Can you share the output of the following command executed from the CLI of your Nagios Log Server machine:

Code: Select all

ntpdate -u pool.ntp.org

Is this environment offline or behind a proxy? Does your organization use an internal NTP server? The ntpdate command may need to be modified.

Issue is now ok. fixed by updating the ntpdate -u pool.ntp.org.
Thanks!
