<div dir="ltr"><span style="font-family:arial,sans-serif;font-size:13px">Hahaha word, Mr. Fedde. Nagios is awesome at what it does, but the configuration is pretty daunting. The default installation comes with a ton of examples which, while ultimately edifying, make it pretty hard to figure out where to start. Nagios is necessarily very flexible, but that flexibility also leads to all kinds of bizarre configurations and functionality. If you've ever looked at an unfamiliar Nagios installation, you've almost definitely wondered what drug addict set it up, and I'm sure that anyone who looks at mine thinks the same.</span><div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">It would have been really nice to have had a minimal configuration, so I made one for CentOS that check's <a href="http://cluedenver.org/" target="_blank">cluedenver.org</a> for 'Who is CLUE?' every 15 and e-mails Dave if it can't find the string (after retrying and failing 1 minute later). It's <a href="http://noltechinc.com/files/nagios-cfg.tgz">here</a>. Dave, you can thank me later, when everyone on this list adds this configuration to a server, forgets about it, and bombards you when the site's down.</div><div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">Another great thing to have known about when I first started using Nagios is "nagios -v /etc/nagios/nagios.cfg". It has extremely useful error messages, including that the permissions are wrong on the attached configuration (chown -R root:nagios /etc/nagios/objects && service nagios restart).</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Thu, Sep 4, 2014 at 8:29 PM, Chris Fedde <span dir="ltr"><<a href="mailto:chris@fedde.us" target="_blank">chris@fedde.us</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">What the world needs is a monitoring system that is built out of a bunch of simple scripts that is not nagios.<div><br></div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><br><div class="gmail_quote">On Thu, Sep 4, 2014 at 12:16 PM, Philipp Giddings <span dir="ltr"><<a href="mailto:webmaster@continentalbook.com" target="_blank">webmaster@continentalbook.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">free monitoring service send email on failure<br>
