ID: 11333 Title: aws_agent: enable cache to reduce live data requests Component: Checks & agents Level: 1 Class: Bug fix Version: 2.0.0i1 The first time the AWS agent is executed, it stores data in a cache file and only retrieves live data from the AWS API once the data in this file is considered out-of-date, or the configuration of the agent has changed. This is especially useful, because AWS charges a fee for each query to the API. The mechanism for determining whether the configuration of the agent has changed contained a defect, leading to undeterministic configuration signatures, which the agent erroneously interpreted as a configuration change. This has been fixed.
