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). https://nagios1.private.releng.scl3.mozilla.com/releng-scl3/cgi-bin/history.cgi?host=all Error: Cannot open log file '/var/log/nagios/nagios.log' for reading!
This appears to be a bug introduced with Nagios 4 . 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.  - https://github.com/NagiosEnterprises/nagioscore/issues/303
