We have several monitoring tools for specialized purposes - HyperIC,
AppDynamics, Splunk, SiteScope, PRTG, and now Nagios. I'm not a DevOps
guy, just a seasoned *nix system admin, but I like the DevOps idea (as long
as the devs don't get access to directly modify production servers).
I have recently been extremely impressed by the puppet collections magic
that Example42.com's puppet-nagios [1], and puppet-nrpe [2] modules
provide. I don't mean to advertise someone's puppet modules but I'm quite
new to using Nagios. I've been gunshy of it in the past because it's so
config-file driven.
In a few months, I've been able to do some pretty cool stuff with nagios -
like writing a puppet module to integrate Ex42's config with pnp4Nagios
[3], [4] to provide graphing on services that have performance data, build
nagios contact/groups from Foreman's Host Owner information, and I'm
working toward building Nagios Host Groups from Foreman's Hostgroups.
Ultimately, even though I'm only managing 30-40 systems now, I am very
confident enough in this tool combination to manage large numbers of
systems. Using Foreman and Puppet, I'm still amazed at the massive number
of scripts I've tried to write to accomplish and automate so many complex
tasks in the past (never fully succeeding) and this all just works
auto-magically with a little care and feeding that doesn't increase
linearly with the number of hosts managed.
Best of all, the price is right, as I'm just running Nagios Core. I know
there will eventually be scale issues that arise within Nagios, but we've
got a long way to go in this current environment before I need to migrate
Nagios from a VM to real bare metal or worry about scaling out.

Hello,
having deployed some Nagios monitoring appliances in the last decade, I
wonder what is the current top tools for DevOps these days. I quickly
searched with Google and it still looks that Nagios is the top
monitoring solution. I have been using Cacti for a while and I know
basics of Zabbix, but haven’t touched any monitoring for a while now.
I am seeking for a lightweight and easy to configure monitoring of very
basic resources and services. But I want on-line graphs. Was wondering
what is the best tool that could maybe be worth integration into Foreman
(as plug-in).
So what DevOps use?
Thanks for tips and experiences.
