This allows one to use regular expressions to + select interfaces, too. + * ipmi plugin: Handle temporary IPMI error conditions more gracefully. + Thanks to Bruno Prémont for this patch. + * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern + for the patch. + * mysql plugin: Allow connecting to a database via the UNIX domain + socket, too.
