This might also apply to the mdc1 server, but I can't get to the web interface of that to check (will file a separate bug for that if one isn't already on file).

Error: Cannot open log file '/var/log/nagios/nagios.log' for reading!

[Keegan Ferrando [:fauweh]]

This appears to be a bug introduced with Nagios 4 [1]. The nagios log is being created 0600 instead of the old standard of 0644 so httpd cannot open the log. I have manually chmod'ed the log to 0640 and it can now be read, for at least the next few hours until the log is rolled again.

TLDR; We'll need to Nagios 4.3.0 to be released in epel for a permanent fix but we may be able to get a cron job to change the permissions after log rotate, for now. Will follow with ryanc about this option.
