The diskstat check for Linux has been reimplemented from scratch. It now gets much more specific metrics information like average wait time, IO queue length, latency, IOs per seconds und more. Six graphs are being created.

Note: this check is new parametrized by a new rule set in WATO. You need to redo your configuration of this check, sorry. Also if you have a very old legacy setup with two seperate checks for read and write, you also need to rediscover. These checks are not longer supported.
