Hi,

I had sensu server and client running on different machines and are properly communicating as I had few checks are working .

When I installed mongodb plugin fron github (https://github.com/sensu-plugins/sensu-plugins-mongodb) and I can execute ruby script manually from client .But from sensu server is not executing the script and throwing the below error:

{“timestamp”:“2015-12-07T06:25:56.325382+0000”,“level”:“info”,“message”:“publishing check result”,“payload”:{“client”:“internal._dev0.sensuclient.2”,“check”:{“name”:“Mongodb_Metrics”,“issued”:1449469525,“command”:"/usr/bin/env /etc/sensu/plugins/metrics-mongodb.rb",“executed”:1449469555,“duration”:0.571,“output”:"/opt/sensu/embedded/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require': cannot load such file -- mongo (LoadError)\n\tfrom /opt/sensu/embedded/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire’\n\tfrom /etc/sensu/plugins/metrics-mongodb.rb:33:in `’\nSensu::Plugin::CLI: [“Not implemented! You should override Sensu::Plugin::CLI#run.”]\n",“status”:3}}}

I tried all the possibilities but could not resolve it,Please help me out

Sounds like you need to install the mongo rubygem:"

This is a dependency of this gem:

          s.add_development_dependency 'rubocop',                   '0.32.1'

I recommend plugins using /opt/sensu/embedded/gem install sensu-plugins-mongodb
to ensure that gem installs a plugin with all its dependencies if
using the embedded ruby like that.
