Looking for ideas here on a modern way of documenting an enterprise IT
infrastructure. Ideally, no cost / open source. Something like MediaWiki
but perhaps with features that show system depencencies & relationships
(network services, storage, OS, backups, SNMP or similar, monitoring, etc.)
Main focus is documenting the infrastructure, perhaps to include
screenshots, graphics, schematics, code boxes for conf files & scripts, etc.
Suggestions of useful, reliable, non-free tools will be considered.
Would be cool if it had a dashboard for management.
