This plugin provides native HAProxy instrumentation for monitoring and metrics collection, including: service health and backend server metrics.

At the moment it's only possible to configure a warning and critical percentage for all services. But if there are 100 backends and 99 backends are UP and all the servers of one backend are down, I would still very much like to get a CRITICAL status.
According to the HAProxy manual for 1.5+:
46. req_rate [.F..]: HTTP requests per second over last elapsed second
47. req_rate_max [.F..]: max number of HTTP requests per second observed
The [.F..] indicates these stats are only available for FRONTENDs, and as such, never get rendered since metrics-haproxy.rb uses:
if line[1] == 'BACKEND'
...
unless line[46].nil?
output "#{config[:scheme]}.#{line[0]}.requests_per_second", line[46]
end
unless line[47].nil?
output "#{config[:scheme]}.#{line[0]}.requests_per_second_max", line[47]
end
...It appears that metrics-haproxy.rb don't check any FRONTEND metrics. Is this intentional?
Command: metrics-haproxy.rb -c /var/lib/haproxy/stats
Even when I provide username and password the result is still:
Unable to fetch stats from haproxy after 3 attempts
When I run the metrics command on the command line it gives me stats perfectly fine, the socket is chmod 755.
Any suggestions? Literally all sensu checks work on this server except this one.
Release 2.0.3 is missing on bonsai.
This release is important to fix compatibility with haproxy 2.4
Some maintainer can publish it ? 🙏
Plugin works fine for 2.2.4 but stopped working after upgrade to 2.3.0.

Is a new release planned ?
That last release is out in April 2016 and 9e28d9f would be very useful for us.

I've pulled down the master branch of this gem, and integrated the plugins to my organization's monitoring cookbook. This deploys the sensu plugins to the clients, and uses the embedded Ruby binary at /opt/chef/embedded/bin/ruby. The current version deployed with Chef Client 12.* is Ruby 2.3.0
I'm getting the following feedback

The above is complaining about metrics-haproxy.rb line 145: https://github.com/sensu-plugins/sensu-plugins-haproxy/blob/master/bin/metrics-haproxy.rb#L145
It should be noted that I'm getting the same error here: https://github.com/sensu-plugins/sensu-plugins-haproxy/blob/master/bin/check-haproxy.rb#L201
So far, the only conclusion I can come to is that Ruby 2.3.0 is not yet supported by this plugin, or there is a bug in this use of CSV for this version. Or, possibly this implementation does not support the latest CSV class itself. Any feedback is much appreciated.

Shouldn't be here comparison to limit instead of max? Because otherwise it triggers CRIT everytime you hit new max which can be still way below limit.

It works fine after changing true to false.
Is there any other way how to run the checks other then editing check files?
