The Sensu assets packaged from this repository are built against the Sensu ruby runtime environment. When using these assets as part of a Sensu Go resource (check, mutator or handler), make sure you include the corresponding Sensu ruby runtime asset in the list of assets needed by the resource. The current ruby-runtime assets can be found here in the Bonsai Asset Index.

Ruby does not have a good native way without the use of C extensions to grab information on memory usage (outside of running shell commands and parsing out). Because of this
check-ram.rb uses a gem called
vmstat which has a somewhat annoying dependency on a gcc to compile the C extensions. In order to not force people to install gcc if they are not using
check-ram.rb we do not install it by default, and is up to the user to make sure that they install it. This requires two steps and can vary based on your distribution and ruby set up:
gcc. If you are on a debian based system it is located in the
vmstatgem into the path that sensu gems are expected to run from:
sudo /opt/sensu/embedded/bin/gem install vmstat --no-rdoc --no-rior the equivalent for installing sensu gems in your configuration management system
