Well, i cannot say fascinated, since i've used it on home computer (fairly complex smartos environment with dozens of machines).
Currently i use Cacti, since i do not wish not to use agent software if
possible.
I just don't trust anyone
Check out the new Cacti, it's quite nice nowdays and even looks fancy.
SNMP is quite enough for 95% of monitoring. To bad is not widely accepted.
For else i have (for now) crontab with various stats* and plot.
This is for drill down analysis if required.
As for Prometheus, i actually love those kind of products you mention.
A lot of options and features, complex.
It's a kind of product you think upfront what you want, then fire and forget.
As for features - if we talk whole stack....
I like API - get graph with URL, inputting what you want directly into url.
When you draw a graph from gui it gives you a nice URL to use as well (or send around).
Language is not strange to me (GO), i personally like it and explored it a bit, should work on just any unix out there.
Alerting API is quite broad. From mails to endpoint API(s) to various stuff.
Last but not least, official client libs for java, ruby, go and scala.
Other unofficial in large numbers.
Include metrics in your apps is something i have yet to see from others
This can lower the debug time and/or expensive software such as dynatrace.
Since you are a ruby fan, take it for a spin
It's really fast with nginx infront(reverse proxy and internal load balancer), even on couple of AMD FM1 cores @ home, running that and dozens of smartos vms in virtualbox.
I'm willing to suggest this product to replace Cacti completely in my work environment, gradually for new projects.
I'm writing this as totally not affiliated with Prometheus or Cacti in any way.

Peasant.

Hi All
I am looking for a script that would collect statistics in a summarised format.

Something that would allow me to profile the environment based on a 1 line output that I could run every 15 min.

ruby-switch
RUBY-SWITCH(1) RUBY-SWITCH(1) NAME
ruby-switch - switch between different Ruby interpreters USAGE
ruby-switch --list ruby-switch --check ruby-switch --set RUBYVERSION ruby-switch --auto DESCRIPTION
ruby-switch can be used to easily switch to different Ruby interpreters as the default system-wide interpreter for your Debian system. When run with --list, all supported Ruby interpreters are listed. When --check is passed, ruby-switch will check which Ruby interpreter is currently being used. If the settings are inconsistent -- e.g. `ruby` is Ruby 1.8 and `gem` is using Ruby 1.9.1, ruby-switch will issue a big warning. When --set RUBYINTERPRETER is used ruby-switch will switch your system to the corresponding Ruby interpreter. This includes, for example, the default implementations for the following programs: ruby, gem, irb, erb, testrb, rdoc, ri. ruby-switch --set auto will make your system use the default Ruby interpreter currently suggested by Debian. OPTIONS
-h, --help Displays the help and exits. A NOTE ON RUBY 1.9.x Ruby uses two parallel versioning schemes: the `Ruby library compatibility version' (1.9.1 at the time of writing this), which is similar to a library SONAME, and the `Ruby version' (1.9.3 is about to be released at the time of writing). Ruby packages in Debian are named using the Ruby library compatibility version, which is sometimes confusing for users who do not follow Ruby development closely. ruby-switch also uses the Ruby library compatibility version, so specifying `ruby1.9.1' might give you Ruby with version 1.9.2, or with version 1.9.3, depending on the current Ruby version of the `ruby1.9.1' package.
