I always liked administering nagios. It was sometimes hard to understand since so many tutorials were only concerned with setting up sensors on the nagios server. ssh to localhost? What? Once I had it sorted out, it was satisfactory. I could turn off alert
emails from knotheaded processes while I sorted them out. It was an extra step to turn off alerts from machines that were getting offline maintenance. I think you are right that some people who are charged with administrating Nagios, just want to look at
the pretty web front end. That is like you saying you administer the Gmail servers because you have a mail account. lol<br>

So the issue wasn't Nagios - it was the folks managing it.<br>
<br>
Nagios is a great tool and we use it in Production. As you sort of allude to it is configurable so you don't have to use defaults. Not only that it allows you to create your own monitors easily. We've created some very esoteric monitors for various purposes
such as snmp checks for air handlers, web checks for a variety of different scenarios (they're not all as simple as seeing if the web page is responding) and determining which node of a cluster has the actual service running at this moment. You can use
snmp checks or you can do full scripting on your various servers by adding nrpe (UNIX/Linux) or NSClient++ (Windows).<br>
<br>
The benefit to using a monitoring system is you set it not for your "properly" configured but rather for what occurs when it quits behaving "properly". It is much the same as performance tuning. You set up things the way you expect them to work then adjust
for the reality of what you're actually observing.<br>
<br>
The problem you describe happens with any monitoring system in which people managing the tool don't actually manage it. At a Fortune 500 company I used to work at we had a rather pricey monitoring system in place and it was somewhat annoying because all it
really did was page me endlessly in the middle of working on a problem. Nagios at least allows end users to acknowledge problems once they occur which:<br>
a) Lets others who see the alert see also that it has been acknowledged.<br>
b) Stops sending out needless emails and pages until the issue clears.<br>
<br>
It is amusing to me that we have a group here that complains they don't want our Nagios alerts because they say they do their own monitoring but I often have to let them know when something is down because I see it in Nagios and they don't have a clue it is
an issue until I tell them.<br>

My experience with Nagios in production was a bad one but only because the people who were doing it paid no attention to the nominal operating behavior of the servers being monitored and relied on dead-stupid broad-brush configurations that alarmed all the
time uselessly. And they wouldn't revisit their configurations in any sort of reasonable way because, well, that was *work*; you had to *think*! The moral is that in typical (by which I mean over-servered in the extreme) environments, in order to use Nagios
effectively you wind up having to put in the kind of thought and effort that would have best been put into setting up reliable systems in the first place. It's a bit like a racing team putting half their effort into the efficiency of their tow trucks. :)<br>
<br>
A Puppet set up I encountered as my IT career was ending had a similar problem, but it tended to hold everything back; whenever you wanted to advance anything - change to a new version of a Linux distribution (if you're stuck in that kind of goat-rope) or introduce
a new distribution<br>
- you had to drag the Puppet implementation along collaterally and it seemed as though people would rather run ancient versions of stuff and suffer those consequences than do the dragging. If anything, it seemed to me that Puppet and the like get used to facilitate
practices that shouldn't be occurring in the first place: server overprofileration.<br>
