What software can be used to monitor website setups

When I have a network of multiple websites that can span different domains. What software solutions are available that can check if everything is set up correctly?

I would like to have features like this:

• The software can be started with a list of domain names that should be checked

• It then opens the index.html websites of all these domains and collects a list of all files that are available under these domains by crawling through the content.

• It checks for broken links (also to external websites) and reports them

• It checks if all the certificates are set up correctly.

• It scans the Javascript code for Websocket connections and checks if it can make a connection

• It collects the hashes of all file and remembers them. If started a second time it lists all files that have changed since the last time. (As well as all new files and all files that have been deleted).

• It checks if all servers are available with ipv4 and ipv6
