ID: 15577 Title: elasticsearch_nodes: Check plugin didn't consider ruleset Component: Checks & agents Level: 1 Class: Bug fix Version: 2.3.0b1 The parameter name in the WATO ruleset and in the check plugin were different. Because of that the check plugin didn't consider the values from the ruleset. This has now been fixed and the check plugin now considers the ruleset values.
