Well this step below that I took is not documented anywhere. But based on your documentation which explains how to sensu-install disk check - i applied same anology to install mysql checks on my sensu -client
here is the command given on my debian 8 system
sensu-install -p mysql
- I got the following error
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
What could have gone wrong here?
