See the table below for minimum permissions for each check.
| Check | Permissions |
|---|---|
| check-mysql-alive.rb | SELECT |
| check-mysql-connections.rb | SELECT |
| check-mysql-disk.rb | SELECT |
| check-mysql-innodb-lock.rb | PROCESS |
| check-mysql-query-result-count.rb | depends on query |
| check-mysql-select-count.rb | SELECT |
| check-mysql-replication-status.rb | SUPER OR REPLICATION_CLIENT (the latter is preferable) |
| check-mysql-msr-replication-status.rb | SELECT |
| check-mysql-status.rb | SELECT |
| check-mysql-threads.rb | SELECT |
| metrics-mysql-graphite.rb | SELECT |
| metrics-mysql-processes.rb | SELECT |
| metrics-mysql-query-result-count.rb | depends on query |
| metrics-mysql-select-count.rb | depends on query |
| metrics-mysql-multiple-select-count | depends on query |
| metrics-mysql-raw.rb | SELECT |
| metrics-mysql.rb | INSERT into sensumetrics.sensu_historic_metrics |
I would recommend using different users when you need to have more than RO access (REPLICATION_CLIENT or using the metrics handler) to limit the potential ramifications of that user being compromised.
The ruby executables are install in path similar to /opt/sensu/embedded/lib/ruby/gems/2.0.0/gems/sensu-plugins-mysql-0.0.4/bin
When used in chef, if the dependencies are missing, an error may abort the chef-client run:
*** 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.This may be fixed by installing the mysql client library before the plugin:
# http://serverfault.com/questions/415392/install-mysql-gem-for-use-in-chef-client
package "libmysqlclient-dev" do
action :install
end
sensu_gem 'sensu-plugins-mysql' do version '0.0.4' end
