Tool or scripts to check configurations

We have several web servers and weblogic nodes that we need to make sure configurations between them are matching since they are clustered the configurations in each group match.
What does everyone use for making sure system configurations match?
Currently I use puppet for somethings to make sure ntp, chrony, sysctl.conf type settings are set within puppet on our Satellite server.
Management is wanting something that is automated to say if systems match and if configurations changed between them.
They do understand there will be a few differences with IP and network. The big piece is application differences and such.
Our nodes are mixed between RHEL 7 and 6 most are RHEL 7

Thanks in advance
