It retains either one or two -statistic sets per host. If the client has a clean configuration state, -the most recent (clean) record is retained. If the client has a dirty -configuration state, two records are retained. One record is the last -clean record.

In order to address this, -we opted to use the retention scheme described above. This approach has -several shortcomings: - -* A comprehensive list of reconfiguration operations (with associated - timestamps) isn't retained -* Client results for any given day (except the last one) aren't uniformly - retained. This means that inter-client analysis is difficult, if - not impossible - -We plan to move to a database backend to address the dataset size -problem and start retaining all information. The move to a SQL backend -will allow many more types of queries to be efficiently processed. It -will also make on-demand reports simpler. - -Other sorts of information would also be useful to track. We plan to -add the ability to tag a particular configuration element as security -related, and include this in reports. This will aid in the effective -prioritization of manual and failed reconfiguration tasks. - -Capability Goals (posed as questions) -------------------------------------- - -* What machines have not yet applied critical updates? -* How long did critical updates take to be applied? -* What configuration did machine X have on a particular date? -* When did machine X perform configuration update Y? -- cgit v1.2.3-1-g7c22
