[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.
For details: http://www.ruby-lang.org/bugreport.html

[1]    15323 abort      ./check-percona-cluster-size.rb --user xxxxxx --password xxxxxx

Please note that using the official mariadb apt repository, libmariadb-dev is installed instead of libmysqlclient-dev.

I'm not a ruby expert, bug i guess it could be related to the using of outdated mysql2 gem (0.4.8 vs 0.5.2)

majormoses commented 6 years ago

I dont have much experience with mariadb vs mysql compatibility issues. I looked at https://github.com/brianmario/mysql2/releases/tag/0.5.0 and there are some breaking changes, I would have to look at what the current supported versions of mysql are and if its something we can can stomach doing (in a major release). Also I note that this is a percona specific repo (although it should have most mysql compatibility) have you tried the more vanilla mysql plugins? https://github.com/sensu-plugins/sensu-plugins-mysql

nervo commented 6 years ago

@majormoses we are both using mysql and percona sensu plugin for their complementarity (such as aliveness on mysql side and galera cluster-size on percona side) If that's the question, we don't have such issue with sensu-plugins-mysql :)

nervo commented 6 years ago

@majormoses feel free to ask me for any tests
